A kind of anti-tensile high hardness oil field oil pipe

Abstract

The invention relates to the technical field of petroleum exploitation equipment, in particular to an oil pipe with high tensile strength and high hardness, comprising an oil pipe body and an oil pipe installation device, wherein the oil pipe installation device comprises a U-shaped base, and the bottom wall of the U-shaped base has two left and right sides. There are several limit chute equidistantly on the end, and a limit slider is arranged in the limit chute, and the upper surface of the limit slider is provided with a first rotating member, which is located at the bottom of the U-shaped base. An arc-shaped oil pipe support plate is arranged above, the oil pipe body includes an outer protection pipe and an inner oil pipe, the outer protection pipe is placed on the arc-shaped oil pipe support plate, and the outer protection pipe is fixed by an arc-shaped clamping strip; the oil pipe When the body is impacted by the outside world, its impact resistance is stronger, which effectively avoids the deformation or damage of the tubing body caused by the external impact force, and it is easy to operate, excellent in sealing effect, and strong in practicability when connecting the pipeline.

Description

technical field [0001] The invention relates to the technical field of oil exploitation equipment, in particular to a stretch-resistant high-hardness oil pipe for oilfields. 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 production process. The main purpose of the oil pipe is to be lowered into the well and used as a pipe for liquid production or liquid injection. [0003] The common tubing used for oil field exploration is the tubing used for oil field exploration with high tensile strength and high hardness. It is mainly divided into two parts. For that use, excellent properties of tensile resistance and high strength are required. However, when the oil pipe is used as oil transportation, it is vulnerable to external shocks and causes deformation or damage to the pipe body; at the same time...

AI Technical Summary

Problems solved by technology

The stretch-resistant and high-hardness tubing used for oil field exploration, through the combination of the upper tubing, the moving block and the lower tubing, allows the staff to move the moving block at the end of the tubing connection according to the length of the tubing during the connection work. Drive the lower oil pipe and the upper oil pipe to slide relative to each other, so as to adjust the length of the oil pipe composed of the lower oil pipe and the upper oil pipe in real time. Although the whole design enables the length of the exploration oil pipe to be adjustable, its adjustment range is limited. When collecting For deeper oil wells, it is still necessary to use two tubing connections together

In addition, the oil pipeline in this oil field is vulnerable to external impact when transporting oil, and the single-layer design of the entire pipeline is vulnerable to impact deformation or damage, resulting in oil leakage during transportation
