Description
Technical Field
The application relates to the technical field of natural gas and petroleum exploitation, in particular to a downhole applier and a downhole tool assembly.
Background
Currently, when a downhole tool is lowered into an oil and gas well, a release tool is coupled to the downhole tool by a pin, and then the release tool moves the downhole tool to a predetermined location within the oil and gas well. After reaching the predetermined location, the pin is broken by jolting, thereby leaving the downhole tool in the predetermined location in the hydrocarbon well. The above-described dispensing process is not suitable for use in large-well-deviation oil and gas wells. When the application tool drives the downhole tool to move to a position with larger inclination in the oil and gas well, the vibration force cannot be effectively transmitted to the joint of the application tool and the downhole tool, so that a pin connecting the application tool and the downhole tool cannot be broken, and the downhole tool cannot be separated from the application tool.

Example 1:
FIG. 1 is a cross-sectional, physical view of a downhole applier 100 according to the present embodiment, showing the stop member 120 in a stop position. FIG. 2 is a schematic cross-sectional view of the downhole applier 100 according to the present embodiment, showing the stop member 120 in the expanded position.
Referring to fig. 1 and 2 in combination, an embodiment of the present application provides a downhole applier 100 including a base 110, a limiting member 120, a applier member 130, an elastic member 140, and a connecting member 150.
The base 110 is cylindrical and the upper end of the base 110 is adapted to be coupled to a fishing assembly so that the downhole applier 100 can move up and down in the well. The base 110 is provided with a working chamber 111 extending along its axis. The working chamber 111 extends upward from the lower end of the base 110. A radially extending working hole 112 is provided in the outer peripheral surface of the lower end of the base 110. The working hole 112 communicates the working chamber 111 with the outside.
Two stop members 120 are movably disposed within the working chamber 111. The two stop members 120 are configured to reciprocate radially between a stop position (shown in fig. 1) adjacent one another and an expanded position (shown in fig. 2) spaced apart from one another. It should be noted that the number of the limiting members 120 is not limited to two, and in other embodiments, three or more limiting members 120 may be provided. It should also be noted that the stop member 120 may be movably disposed within the working chamber 111 in a variety of ways. In this embodiment, the limiting member 120 is rotatably disposed within the working chamber 111. Specifically, the downhole applier 100 further includes a shaft 101. The rotary shaft 101 is fixedly connected with the base 110, and the rotary shaft 101 is disposed at the upper portion of the working chamber 111. The upper part of the limiting member 120 is rotatably coupled to the rotation shaft 101. When the stop members 120 move from the expanded position to the stop position, the lower portions of the two stop members 120 move radially inward and toward each other. When the spacing members 120 are moved from the spacing position to the expanded position, the lower portions of the two spacing members 120 move radially outwardly and away from each other.
The application member 130 has a columnar shape extending in the axial direction of the base 110. An application member 130 is axially movably disposed within working chamber 111. The application member 130 is disposed below the stop member 120. The application member 130 is reciprocally movable between a locked position (shown in FIG. 1) and a released position (shown in FIG. 2). The locking position is located below the release position.
The elastic member 140 applies an elastic force to the application member 130 such that the application member 130 always has a tendency to move toward the release position. Specifically, in the present embodiment, the elastic member 140 is a spring, and the elastic member 140 is sleeved on the applying member 130. The upper end of the elastic member 140 acts on the application member 130, and the lower end acts on the base 110. The elastic member 140 is always in a compressed state, thereby applying an elastic force to the application member 130, so that the application member 130 always has a tendency to move toward the release position.
The connection member 150 is disposed in the working chamber 111 and corresponds to the working hole 112. When the application member 130 is in the locked position, a portion of the connecting member 150 protrudes from the working aperture 112 to the outside of the base 110 under compression of the application member 130. When the application member 130 is in the release position, the connecting member 150 can be forced completely into the base 110 by external forces. In this embodiment, the connection member 150 is a sphere, and the diameter of the connection member 150 is larger than that of the working hole 112, so that the connection member 150 is separated from the base 110. The spherical connecting member 150 can be moved out of the base 110 by the pressing of the applying member 130 more easily, and can be returned to the base 110 completely by the external force more easily.
When the spacing member 120 is in the spacing position, the lower end of the spacing member 120 abuts the upper end of the application member 130 to maintain the application member 130 in the locked position. With the application member 130 in the locked position, the application member 130 presses against the connecting member 150 such that a portion of the connecting member 150 extends outside the base 110 through the working aperture 112. The downhole applicator 100 is capable of being coupled to a downhole tool to move the downhole tool to a predetermined location within a hydrocarbon well through a coupling member 150 extending outside of the base 110. When the limiting members 120 are positioned at the expanded position, the accommodating spaces 120a are formed between the limiting members 120, and the applying member 130 enters the accommodating spaces 120a and moves to the release position under the action of the elastic member 140. With the application member 130 in the release position, the connecting member 150 can be forced completely into the base 110 by external forces. At this point, the connection member 150 can be fully advanced into the base 110 under compression by the downhole tool, thereby allowing the downhole tool to be disengaged from the downhole applier 100. The downhole applier 100 provided in this embodiment can apply a downhole tool without jolting by only moving the stop member 120 from the stop position to the expanded position. This allows the downhole applier 100 provided by the present embodiment to be adapted to large deviated wells and to apply the downhole tool to a more inclined location within the well.
The movement of the stop member 120 between the stop position and the extended position may be controlled by a motor or other power means. To simplify the structure and also to improve reliability, in this embodiment, the stop member 120 is urged to move from the stop position to the expanded position by the application member 130. Specifically, the downhole applier 100 further includes a locking mechanism 160, the locking mechanism 160 being configured to transition between a locked state and an unlocked state. When the locking mechanism 160 is in the locked state, the limiting member 120 is maintained at the limiting position; when the locking mechanism 160 is in the unlocked state, the stop member 120 is moved to the expanded position by the urging of the application member 130.
In order to enable the application member 130 to more smoothly push the stopper member 120 to the expanded position, in the present embodiment, the lower end of the stopper member 120 is provided with a contact slope 121, and the contact slope 121 is configured to abut against the upper end of the application member 130. When the locking mechanism 160 is in the unlocked state, the limiting member 120 can smoothly push the limiting member 120 to move to the expanded position by contacting the inclined surface 121.
Further, in the present embodiment, the upper end of the application member 130 is tapered to mate with the contact slope 121. By the tapered upper end of the application member 130 being in contact with the contact slope 121, the sensitivity of the movement of the stopper member 120 and the application member 130 can be further improved, so that the stopper member 120 can be smoothly moved to the expanded position and the application member 130 can be smoothly moved to the released position.
Further, in this embodiment, the downhole applier 100 includes two locking mechanisms 160, one locking mechanism 160 being coupled to each of the stop members 120. The two locking mechanisms 160 are configured to cooperate with each other when the spacing member 120 is in the spacing position to maintain the spacing member 120 in the spacing position; the two locking mechanisms 160 are configured to separate from each other under the force of an external force when mated to enable movement of the stop member 120 to the expanded position.
Further, in the present embodiment, the base 110 is provided with an operation port 113 that communicates with the working chamber 111 and the outside in the radial direction. The locking mechanism 160 extends to the outside of the base 110 through the operation port 113.
Further, in the present embodiment, the locking mechanism 160 includes a fixed shaft 161 and a locking body 162; the fixed shaft 161 is fixedly connected to the limiting member 120, and the locking body 162 is rotatably engaged with the fixed shaft 161. The locking body 162 is provided with a locking groove 162a; the fixing shaft 161 of one locking mechanism 160 can be fitted into the locking groove 162a of the locking body 162 of the other locking mechanism 160 to maintain the two limiting members 120 at the limiting positions close to each other. The locking body 162 of one locking mechanism 160 can be separated from the fixed shaft 161 of the other locking mechanism 160 under the action of external force so that the limiting members 120 can be separated from each other; the locking body 162 extends to the outside of the base 110 through the operation port 113. Specifically, when the two locking mechanisms 160 are fitted to each other, the locking groove 162a of the locking body 162 of one locking mechanism 160 is fitted to the fixed shaft 161 of the other locking mechanism 160 in the bottom-to-top direction. When the downhole applier 100 is lowered in the hydrocarbon well, the inner wall of the portion of the locking body 162 located outside the base 110 rubs against the hydrocarbon well, and the generated force makes the fixing shaft 161 always unable to be separated from the locking groove 162a engaged therewith. After the downhole applier 100 reaches a predetermined position in the hydrocarbon well, the downhole applier 100 is lifted upward, at this time, the inner wall of the hydrocarbon well at the position where the locking body 162 is located outside the base 110 is rubbed, the locking body 162 is rotated in a direction away from the fixed shaft 161 engaged therewith by the generated force, the locking body 162 is disengaged from the fixed shaft 161 engaged therewith, the two locking mechanisms 160 are separated from each other, and the limiting member 120 can be moved to the expanded position.
Example 2:
The present embodiment provides a downhole tool assembly 010. Fig. 3 is a schematic cross-sectional view of the downhole tool assembly 010 according to the present embodiment. The downhole tool assembly 010 includes the downhole applicator 100 and the downhole tool 200 described in example 1. The upper end of the downhole tool 200 is provided with a receiving slot 210, and the lower end of the base 110 of the downhole applicator 100 is inserted into the receiving slot 210. The inner wall of the receiving groove 210 is provided with a connection hole 211 corresponding to the working hole 112. When the spacing member 120 is in the spacing position, the coupling member 150 is inserted into the coupling hole 211, thereby coupling the downhole applier 100 and the downhole tool 200 together. As the stop member 120 is moved to the expanded position, the upward movement of the application member 130 provides room for the radially inward movement of the connecting member 150. Because the downhole applier 100 is lifted upward at this point, the downhole applier 100 and the downhole tool 200 co-squeeze the coupling members 150, moving the coupling members 150 radially inward and out of the coupling holes 211, thereby enabling the downhole tool 200 to be disengaged from the downhole applier 100. The downhole tool assembly 010 provided in this embodiment can apply the downhole tool 200 without jolting by only lifting the downhole applicator 100 upward to move the spacing member 120 from the spacing position to the expanded position. This allows the downhole tool assembly 010 provided by the present embodiment to be adapted for use in a large deviated well and to be able to apply the downhole tool 200 to a location of greater inclination within the well.
The above description is only a few embodiments of the present application and is not intended to limit the present application, and various modifications and variations will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
