Abstract
The invention discloses an oil pipe stabilizer and an application method, relating to an oil field eccentric wear prevention technology. The oil pipe stabilizer is formed by a plastic body, a rigidity support body, a shaft and a pin plate in connection way. The rigidity support body is arranged in the plastic body. The shaft is connected with the pin plate. The service life of the sleeve is prolonged by the invention.
Description
One, technical field: the present invention relates to a kind of oil pipeline anti-eccentric wear technology, especially tubing centrilizer and using method.
Two, background technology: along with the oil field development time increases, oil, well sleeve pipe wear out and prevent that problem is more and more outstanding.Sleeve pipe particularly, along with the increasing of mining inetesity, pump is following more dark more, and various well stimulations are constantly strengthened, and the chemistry and the mechanical measure of series such as pressure break, acidifying, de-plugging, shutoff all can cause damage to sleeve pipe, and the fracture of sleeve pipe, inconsistent phenomenon are more and more.In this case, have to carry out the sidetracking overhaul.Therefore, the quantity of directional well, horizontal well is increasing gradually.The increase of inclined shaft such as directional well and horizontal well, the eccentric wear of sleeve pipe are again distinct issues.Particularly gradient is greater than the producing wells of 8 degree, because production tube removes the increase of number of times, and in the outside of the tilting section of sleeve pipe, more and more severe by the wearing and tearing of oil pipe joint hoop.Deep sleeve pipe tilting section shows that according to down-hole photograph data the polishing scratch groove is circular-arc.Gash depth does not wait, shallow 2-4 millimeter, and dark 4-7 millimeter, saturating near mill.After the top production string put forward, sloping portion also had the noticeable wear groove.In case and casing wear or millions of unit do not take measures, oil-water well is only scrapped, and loses bigger.Therefore the oil field casing control is a big problem, and sleeve pipe is prevented eccentric wear urgent problem especially.
Three, summary of the invention: the purpose of this invention is to provide a kind of tubing centrilizer and using method, it has solved the shortcoming that other technology exists, the object of the present invention is achieved like this, it is to be formed by connecting by plastic body, rigidity supporter, axle, pin plate, the rigidity supporter is arranged in plastic body, and be connected with pin plate by axle.
Plastic body is to be formed by connecting by two semicircle gum covers, the both sides of two semicircle gum covers are evenly distributed with inserts pawl and socket, and the slotting pawl on two semicircle gum cover both sides and socket intersect correspondence mutually, on the slotting pawl on two semicircle gum covers one side, the circular shaft hole is arranged respectively, pin plate rectangle jack is arranged on the slotting pawl of its another side, and the centre of two semicircle gum cover inwalls has half slot respectively.
The rigidity supporter is made up of two semicircle supporters, the both sides of two semicircle supporters are evenly distributed with inserts pawl and socket, and the slotting pawl on two semicircle supporter both sides and socket intersect correspondence mutually, on two semicircle supporters slotting pawl on one side, the circular shaft hole is arranged, pin plate rectangle jack is arranged on the slotting pawl of its another side, and the structure of rigidity supporter is all corresponding with garment bag; On two semicircle supporters of rigidity supporter reinforcing rib is arranged respectively, the reinforcing rib inwall is welding arc sheetmetal.
The rigidity supporter adopts No. 65 spring steel of thickness 1.5-2 millimeter, and it handles Brinell hardness is≤285, or is not less than other material replacement of No. 60 spring steel with comprehensive mechanical performance.
Axle and pin plate adopt the 3Cr13 stainless steel, and its heat treatment (modified) hardness is HB208-240.
Plastic body is with 85% nitrile rubber, 10% poly-alum, 5% flexibilizer mixed material.
The physical performance index of plastic body is as follows: continue your A80 ± 5 of hardness; Hot strength MPa 〉=10.78; Elongation rate of tensile failure 〉=300%; Permanent deformation 〉=1.7%; 120 ℃ of ageing tests, 24h 〉=0.75; Brittleness temperature ℃≤-30; Tearing strength kN/m
2〉=1.60.
Plastic body and rigidity supporter bond strength MPa 〉=2.5.
Using method: general 1 tubing centrilizer of every oil pipe, be installed in from 1 meter of tubing coupling, 1 mouthful of well consumption 10-30 only, only in the oil pipe bottom with need set upright certain applications; During installation, be sure not the centralizer direction oppositely, should make the big end of centralizer pin clamp is the top; Must test to casing inner diameter with the drift size gauge tool that is slightly larger than the centralizer external diameter before the following centralizer, tubing centrilizer under the casing string incompatibility of fracture, calliper is arranged.
The present invention has prolonged the application life of sleeve pipe.
