Abstract
The utility model discloses an antiseptic thread-gluing-preventing oil casing pipe coupling which relates to an oil production matching tools. The antiseptic thread-gluing-preventing oil casing pipe coupling aims to provide the antiseptic thread-gluing-preventing oil casing pipe coupling with simple structure, low cost and long service life. The antiseptic thread-gluing-preventing oil casing pipe coupling comprises a hollow cylinderical body, wherein through holes are arranged along the axial direction in the body; the inner wall of each through hole is provided with an internal thread; and the outer surface of the body and the inner walls of the through holes are coated with a tungsten-based amorphous alloy layer.
Description
Technical field
The utility model relates to a kind of oil recovery kit, particularly relates to a kind of box cupling that is used to connect tubing and casing.
Background technology
It all is the main oil production method in domestic and international oil field that rod-pumped well recovers the oil all the time, and the tubing and casing box cupling then is a critical component of rod-pumped well, and it plays a part to connect tubing and casing.When oil and gas development, all contain the corrosive medium of multiple compositions such as carbon dioxide, hydrogen sulfide in oil well, gas well, the water injection well, high temperature, high salinity, the hole condition condition is more abominable, often causes perforation of tubing and casing coupling corrosion and disconnected taking off.After producing a period of time, promptly need stop production to overhaul, change box cupling, strengthened cost for oil production, and put to no little inconvenience for the periodicity serialization production of recovering the oil.In the down-hole oil production operation, the thread gluing problem of tubing and casing and tubing and casing box cupling is a difficult problem that exists in domestic each elephant well construction always.Petroleum works technician is alleviated this problem in order to overcome when the oil recovery production operation, be coated with cup grease, anti-thread gluing agent etc. on the screw thread of tubing and casing and tubing and casing box cupling.But these all can increase the extra labour intensity of operative employee, and effect can only keep once, can't satisfy instructions for use fully.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, and cost is low, the anticorrosion and antiadhesion button tubing and casing box cupling of long service life.
The utility model anticorrosion and antiadhesion button tubing and casing box cupling, the body that comprises hollow cylinder, offer through hole vertically in the described body, the inwall of described through hole is provided with internal thread, is covered with a tungsten based amorphous attitude alloy-layer on the external surface of wherein said body and the inwall of through hole.
The utility model anticorrosion and antiadhesion button tubing and casing box cupling, the thickness of wherein said tungsten based amorphous attitude alloy-layer is 30～60 μ m.
The utility model anticorrosion and antiadhesion button tubing and casing box cupling, the material of wherein said body is J55, N80 or the P110 in the API standard.
The utility model anticorrosion and antiadhesion button tubing and casing box cupling has tungsten based amorphous attitude alloy-layer, this coating has extremely excellent corrosion resistance under abominable etching condition such as high chloride ion-containing, carbon dioxide, hydrogen sulfide, high rigidity owing to itself reaches and other bond strength of matrix metallurgical grade simultaneously, the corrosion that alleviates box cupling in the oil producing operation greatly on the one hand, minimizing is because of the frequent situation of changing of coupling corrosion, prolong the time between overhauls(TBO) of oil well, reduced cost for oil production; This box cupling is when being connected with tubing and casing on the other hand, and its screw thread can not stick together with tubing and casing, protects the screw thread of also having protected tubing and casing under the situation of self screw thread, significantly reduces the oil producing operation cost, has prolonged the application life of tubing and casing, improves tar productivity.
Below in conjunction with accompanying drawing anticorrosion and antiadhesion of the present utility model being buckled the tubing and casing box cupling is described further.
Description of drawings
Fig. 1 is the front view of the utility model anticorrosion and antiadhesion button tubing and casing box cupling.
The specific embodiment
As shown in Figure 1, the utility model anticorrosion and antiadhesion button tubing and casing box cupling comprises the body 1 of hollow cylinder, body 1 adopts the J55, the N80 that meet in the API standard or P110 as base material, offer through hole 2 vertically in the body 1, through hole 2 has certain tapering, the inwall of through hole 2 is provided with internal thread 3, internal thread 3 is used for being threaded with tubing and casing, be covered with a tungsten based amorphous attitude alloy-layer on the inwall of the external surface of body 1 and through hole 2, the thickness of tungsten based amorphous attitude alloy-layer is 30～60 μ m.
The utility model anticorrosion and antiadhesion button tubing and casing box cupling is in practical engineering application, and under regulation motor-pumped well moment, last shackle can reach 16 times, can not go out running thread gluing phenomenon, has reduced cost for oil production and working strength of workers, has good economic worth.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
