Definitions

  • the invention relates to the field of oil exploitation, in particular to a sand control screen for horizontal completion.
  • Heavy oil also known as heavy oil, ie high-viscosity heavy crude oil, refers to heavy crude oil with high viscosity, high density, high content of colloid and asphaltene, ie high-viscosity heavy crude oil, generally containing less wax, so crude oil The viscosity is higher, the flow resistance is larger, and the mining is difficult.
  • Heavy oil is an important part of petroleum hydrocarbon energy, and its characteristics are as follows:
  • the main methods for improving heavy oil recovery in China's major oil fields are steam stimulation. And steam drive, but after steam stimulation and steam drive, the degree of recovery can reach 60%, nearly 40% of heavy oil is not produced after high rounds of throughput and steam drive.
  • the steam flooding in the heavy oil reservoir the temperature and pressure of the oil layer changed significantly, and the residual oil saturation between the pores and the residual oil distribution between the wells also changed.
  • the horizontal well is prone to casing damage, screen damage, packer damage or sand production, which seriously affects the development of horizontal wells.
  • the base pipe is placed in the horizontal section of the horizontal completion, and the heavy oil enters into the gap formed between the wire and the sleeve through the wire gap, and after passing through the filtering action of the foam iron, enters the base through the oil inlet hole.
  • the inside of the tube is used to realize the pumping of the oil; in the prior art, the steam flooding technology is adopted in the mining of the heavy oil, that is, the steam injection well and the production well are arranged above the oil reservoir, and the steam is continuously passed through the steam injection well, so that The steam continuously heats the formation around the wellbore, while the crude oil in the formation is also heated, forming a continuous injection with steam in the formation near the wellbore.
  • the wire is composed of a metal support body and a protrusion, and the metal support body has a trapezoidal cross section, the protrusion has a circular arc shape, and the metal support member serves as a support member for the wire, and the short side is connected with the reinforcing rib.
  • the edges are connected to the protrusions, that is, a trapezoidal flow path is formed between the adjacent two metal support sections, and when the mixture of oil and water and the solid phase enters the flow path, The flow channel can actively block the larger diameter solid phase particles, allowing only the oil-water mixture to pass, and the circular curved surface on the outer wall of the protrusion can bounce the large-diameter solid phase and reduce the solid phase and the protrusion when the fluid moves.
  • the contact area makes the filter flow channel formed on the wire not directly contact with the solid phase during the oil recovery process, which reduces the risk of damage to the metal support and prolongs the service life of the wire in the horizontal completion.
  • a plurality of reinforcing ribs are also included, and a plurality of the reinforcing ribs are axially and annularly distributed on the winding wire along the base pipe.
  • the wire In the horizontal section of the horizontal completion, the wire is not only subjected to the pressure of the oil layer, but the pressure changes with the change of the temperature of the oil layer, that is, during the sudden change of the pressure, the wire is extremely vulnerable, and the present invention passes A plurality of annularly distributed reinforcing ribs are arranged on the wire so that the primary filtering unit formed by the winding wire is stably supported to cope with the ever-changing production pressure in the horizontal section of the horizontal completion and to prolong its own service life.
  • the angle formed by the oblique line of the metal support and the vertical line of the axis of the base pipe is 15°-20°.
  • the trapezoidal flow channel inlet, the runner side and the base pipe axis directly determines the diameter of the solid phase entering the secondary filter unit; when the angle is less than 15°, the resistance of the oil-water mixture into the secondary filter unit increases, making the horizontal completion
  • the output is reduced; when the angle is greater than 20°, the amount of the solid phase of the ordinary diameter entering the secondary filtration unit is increased, which increases the filtration load of the foamed iron, and after entering the through hole in the foamed iron, enters the base.
  • the flow rate of the oil-water mixture in the pipe is also reduced, which cannot meet the production requirements of the well.

Abstract

La présente invention concerne un tube filtre de contrôle de sable pour complétion de puits horizontal. Le tube filtre de contrôle de sable comprend un tube de base (4) dont la paroi externe est pourvue d'une pluralité de trous d'entrée de pétrole (5). Une pluralité de nervures de renforcement (3) sont agencées axialement sur la paroi circonférentielle externe du tube de base le long du tube de base, et des fils d'enroulement (2) sont enroulés de façon circonférentielle sur la pluralité de nervures de renforcement le long du tube de base. La position entre deux nervures de renforcement adjacentes est remplie de mousse de fer (8) dans une forme de bloc triangulaire. Lorsque le tube filtre de contrôle du sable fonctionne, le tube de base est placé sur un segment horizontal d'une complétion de puits horizontal. Le pétrole épaissi pénètre dans les espacements formés par les fils d'enroulement et les tubes de revêtement à travers les espacements des fils d'enroulement et pénètre à l'intérieur du tube de base à travers les trous d'entrée de pétrole sous l'effet de filtration de la mousse de fer, de sorte que le pompage de pétrole liquide soit obtenu.
