Abstract
The utility model relates to oil layer fracturing pipe equipment belonging to the field of oil field exploitation and especially relates to a joint with variable diameters and high wear resistance of an oil well fracturing pipeline. The joint with variable diameters and high wear resistance for the oil well fracturing pipeline comprises an upper joint and a lower joint. The joint is a cylindrical casing pipe. The upper part of the casing pipe is the upper joint; the lower part of the casing pipe is the lower joint; a middle circumference of the casing pipe is a polygonal nut; the periphery of the upper joint is provided with an external thread (a); the periphery of the lower joint is provided with an external thread (b); the inner side of the casing pipe is provided with a wear-resisting layer; and the inner diameter of the upper joint is no less than the inner diameter of the lower joint. The joint with variable diameters and high wear resistance for oil well fracturing pipeline possesses compact structure; with the wear-resisting layer, the service life of the joint is effectively prolonged; production cost is thereby reduced to some extent; and labor intensity during joint replacement is also reduced. Variable inner diameter guides fluid in the pipeline and reduces fluid impact to the pipeline.
Description
Technical field
The utility model relates to oilfield exploitation field formation fracturing tube apparatus, relates in particular to the reducer union of a kind of wellfracturing pipeline high abrasion.
Background technology
in the industry of oil field, usually complete with the pressure break pipe in fracturing yield increasing process to oil gas field, adopt the pressure break union to connect between the pressure break pipe, the pressure break union is mainly left-hand thread at present, the structures such as hydraulic pressure and machinery, although these joints can connect adjacent pressure break pipe, but these union function singlenesses, can only play the effect of connection, the fluid of inside is larger to the impact of oil pipe when work, and not anti-high-abrasive material on inwall, cause application life short, need a large amount of manpowers to change, and the actual rear maintain and replace cost that comes into operation is larger, not only impact is produced, and inefficiency.
The utility model content
The utility model is intended to for the deficiency that exists in background technology, and a kind of wellfracturing pipeline high abrasion reducer union that proposes.
Wellfracturing pipeline high abrasion of the present utility model reducer union, to be consisted of by upper interface, lower interface, this joint integral body is cylinder-shaped sleeve, sleeve pipe top is that upper interface, bottom are that lower interface, middle part circumference are the polygon nut body, the periphery that the periphery of upper interface is provided with external screw thread a, lower interface is provided with external screw thread b, the inwall of sleeve pipe is provided with wearing layer, and upper interface internal diameter is not less than the internal diameter of lower interface.
As further improvement of the utility model, the top of described upper interface inwall is provided with annular groove, on the inwall of sleeve pipe at annular groove to have wearing layer.
Wellfracturing pipeline high abrasion of the present utility model reducer union, compact conformation, owing to having increased wearing layer on inwall, effectively extended the application life of joint, saved to a certain extent cost of production, also reduced simultaneously the labour intensity of operator when changing, because internal diameter adopts variable diameter design, the fluid of inside has been played the effect of guiding and reduced the impact of fluid to pipeline.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the reducer union of 1 pair of wellfracturing pipeline high abrasion of the present utility model of accompanying drawing, be described further.
Wellfracturing pipeline high abrasion of the present utility model reducer union, to be consisted of by upper interface 1, lower interface 2, this joint integral body is cylinder-shaped sleeve 3, sleeve pipe 3 tops are that upper interface 1, bottom are that lower interface 2, middle part circumference are polygon nut body 4, the periphery that the periphery of upper interface 1 is provided with external screw thread a5, lower interface 2 is provided with external screw thread b6, the inwall of sleeve pipe 3 is provided with wearing layer 7, and upper interface 1 internal diameter is not less than the internal diameter of lower interface 2.The top of described upper interface 1 inwall is provided with annular groove 8, on the inwall of sleeve pipe 3 at annular groove 8 to have wearing layer 7.
