Embodiment Construction

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] see Figure 1-4 , a kind of oilfield special buckle oil pipe short connection, including an outer pipe 1 and an inner pipe 6, both ends of the outer pipe 1 are fixedly connected with a sealing ring 2, through the setting of the sealing ring 2, the oil pipe short connection is increased. The tightness between the oil pipes can prevent the leakage of liquid, which is convenient for the short-circuiting of the oil pipes and the tr...

Abstract

The invention relates to the technical field of oil pipe pup joints, and discloses an oil field special buckle oil pipe pup joint. The oil field special buckle oil pipe pup joint comprises an outer pipe and an inner pipe; sealing rings are fixedly connected to the two ends of the outer pipe, internal threads are arranged on the inner wall of the right end of an inner cavity of the outer pipe, a connecting handle is fixedly connected to the left end of the inner pipe, and the right end of the inner pipe is fixedly connected with a connecting pipe. According to the oil field special buckle oil pipe pup joint, through the arrangement of the sealing rings, the sealing performance between the oil pipe pup joint and an oil pipe connected with the oil pipe pup joint is improved, liquid leakage can be prevented, the oil pipe pup joint and the oil pipe convey liquid conveniently, and through the arrangement of a buckle and a clamping groove, a spring is in a stretched state in the buckle and clamping groove clamping process; the resilience force of the spring pulls the oil pipe connected with the oil pipe pup joint to move towards the middle of the oil pipe pup joint, connection between theoil pipe pup joint and the oil pipe is tighter, leakage of liquid can be effectively prevented, and reliability of connection between the oil pipes is improved.

Description

technical field [0001] The invention relates to the technical field of oil pipe shorting, in particular to a special oil pipe shorting for oil fields. Background technique [0002] The oil pipe is a pipeline that transports crude oil and natural gas from the oil and gas layer to the surface after the drilling is completed. It is used to withstand the pressure generated during the mining process. When the oil field is exploited, drilling rig equipment is used to form an oil well, and then the oil pipe is inserted into the oil well. In the middle, start the oil pumping equipment to pump out the crude oil. Because the oil well is deep, it is necessary to connect the two oil pipes by shorting the oil pipes. [0003] Both ends of the existing oil pipe short connection are provided with internal threads. When in use, the external thread on the oil pipe can be connected with the internal thread on the oil pipe short connection. Since both ends are threadedly connected, although the...
