Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 1-4 , a special buckle oil pipe short connection in the oil field, 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 oil pipe to be short-circuited and the oil pipe to transport liquid. T...

Abstract

The invention relates to the technical field of oil pipe short connection, and discloses a oil field special buckle oil pipe short connection, which includes an outer pipe and an inner pipe, both ends of the outer pipe are fixedly connected with sealing rings, Internal threads are provided on the inner wall, a connecting handle is fixedly connected to the left end of the inner tube, and a connecting pipe is fixedly connected to the right end of the inner tube. The special buckle of the oil pipe is shorted in the oil field. Through the setting of the sealing ring, the tightness between the shorted oil pipe and the oil pipe connected to it is increased, which can prevent the leakage of liquid and facilitate the short connection of the oil pipe and the delivery of liquid by the oil pipe. When the buckle is connected with the slot, the spring is in a stretched state, and the elastic force of the spring pulls the tubing connected to the tubing short to move toward the middle of the tubing short. The connection between the connection and the oil pipe is tighter, which can effectively prevent the leakage of liquid and improve the reliability of the connection between the oil pipes.

Description

technical field [0001] The invention relates to the technical field of oil pipe short connection, in particular to a oil field special buckle oil pipe short connection. Background technique [0002] The oil pipe is the 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 exploitation process. When the oil field is exploited, the drilling rig equipment is used to drill the oil well first, and then the oil pipe is inserted into the oil well. In the process, the oil pumping equipment is started to pump out the crude oil. Since the oil well is deep, the two oil pipes need to be connected with short-circuited oil pipes. [0003] Both ends of the existing oil pipe short joint 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 joint. Since both ends are thr...
