Definitions

  • ABSTRACT Device for energizing operating members of a submerged installation such as a well head, comprising storage means for a pressurized working fluid, circuit means in communication with said storage means for actuating said operating members by action of the working fluid passing therethrough, and means for pressurizing the working fluid in said storage means, actuated by a pressurized auxiliary fluid such as the drilling fluid.
  • Such an arrangement involves hydraulic pipes connecting the surface installation to the members to be operated.
  • these hydraulic pipes are not only of a high cost, resulting in a significant investment, but are also responsible of troubles for the user.
  • these hydraulic pipes require a permanent maintenance and checking as well as the use of suitable devices for their connection to the well heads.
  • the surface installation must provide an additional power in order to compensate for the pressure losses through the pipes connecting the well head to the surface installation, these pressure losses being in proportion of the pipe length.
  • a device for the storage and use of hydraulic and/or pneumatic power comprising a storage tank for a hydraulic or pneumatic fluid, means for pressurizing said fluid, means for storing and using said pressurized fluid, said means for pressurizing the hydraulic fluid being actuated through a pressurized auxiliary fluid.
  • One of the advantages of the present invention is to make possible the omission of all connections between the well head and the surface installation other than the drill string and the drilling fluid circulation lines.
  • Another advantage of the present invention is to suppress from the surface installation any power generating device required only for the actuation of the drilling well head members.
  • valves 30, 311 designates an oil and air accumulator of any known type, e.g., with a piston or a deformable membrane.
  • This accumulator is connected, through a pipe 2 and valves 3a, 3b, to operating hydraulic devices 40, 4b, respectively, which actuate members, not shown, forming part of the well head equipment, such as blow out preventers, valves etc
  • the control of valves 30, 311 may be achieved, from the surface installation, through any known means, particularly through remote control means (not shown) associated to the well head, the remote control being, for example performed by means of acoustic waves transmitted from the surface installation.
  • the accompanying drawing only shows two operating devices 4a, 4b and their respective control valves 3a, 3b, but this number is by no way limitative and depends exclusively on the member of members of the well head equipment to be controlled.
  • These operating devices are connected through a pipe 5 to the tank 6 of the hydraulic circuit.
  • a non-return valve 7 allows the hydraulic fluid to flow in a single direction, from the operating device to the tank 6.
  • a pipe 8 connects the tank 6 to the accumulator 1 through a non-return valve 9 preventing the discharge of the accumulator 1 into the tank 6.
  • a floating piston 10 slidable in the body 1 1 of tank 6, which tightly separates the upper part from the lower part of said tank 6. This piston may come into abutment against a shoulder 12 at the upper part of tank 6.
  • This tank 6 is surrounded with a cylindrical chamber 13 wherein is slidably mounted a piston 14 having its face, on the side of tank 6, provided with a push-rod 15.
  • a spring 16 maintains piston 14 to its upper position in chamber 13.
  • chamber 13 communicates with the external medium 17 through one or more orifices 18.
  • this external medium is sea water wherein the device is submerged.
  • chamber 13 communicates, on the one hand, with the external medium 17 through a discharge pipe 19 and a valve 20, and, on the other hand, with a pipe 21 through a pipe 22 and a valve 23.
  • Valves 20 and 23 are, for example, hydraulic valves controlled through one-stroke jacks 26 and 27, against the action of repelling devices. Jacks 26 and 27 are respectively fed through pipes 24a and 24b, connected to pipe 2.
  • pipe 21 is connected to a duct 25 for the circulation of the drilling muds.
  • This pipe may be one of the two pipes called in the art choke line and kill line.
  • the well head is necessarily connected to the surface installation through pipes for circulation of the drilling fluid, the pressure of said drilling fluid is used, according to the invention for operating the hydraulic power generating device in a manner which will be stated hereinafter.
  • the pressure of said drilling fluid is used, according to the invention for operating the hydraulic power generating device in a manner which will be stated hereinafter.
  • the device is operated as follows:
  • the device is thus in the state shown in FIG. 1, all the valves such as 3a, 312 being closed.
  • valve 3a When it is desired to actuate a member of the well head, there is transmitted, through a control device (not shown), an order which produces the opening of the valve feeding the corresponding operating device. For example the valve 3a is opened and the hydraulic fluid flows, thereby actuating the operating device 4 a, from accumulator l to tank 6 through pipe 2, valve 3 0, operating device 4 a, pipe 5 and non-return. valve 7.
  • Repelling means 28 actuate valve 20 to a position of closure of pipe 19 and repelling means 29 actuate valve 23 to a position of opening, establishing communication between pipes 22 and 21.
  • the drilling mud which is at a pressure P, is supplied through pipes 25, 21 and 22 to the body 13 where it exerts on the upper face of piston 14 a strength which moves it downwardly in chamber 13 against the antagonistic action of spring 16.
  • valves 20 and 23 push back the valves to the position shown in FIG. 1, thereby producing the opening of the discharging pipe 19 and the interruption of the drilling mud feed to body 13 by closure of valve 23.
  • the spring 16 which has been previously compressed, is released, thereby allowing the piston 14 to rise while expelling the mud contained in the upper portion of chamber 13, through the discharge pipe 19.
  • the pressure exerted by the external medium 17 is the hydrostatic pressure prevailing at the device immersion depth. It is thus obvious for the operation of the device, that the minimum pressure P min in the accumulator 1 is selected equal to or greater than the hydrostatic pressure P, at the considered depth.
