Anti-stretching high-hardness oil pipe for oil field

Abstract

The invention relates to the technical field of oil exploitation equipment, and particularly relates to an anti-stretching high-hardness oil pipe for an oil field. The anti-stretching high-hardness oil pipe comprises an oil pipe body and an oil pipe mounting device, wherein the oil pipe mounting device comprises a U-shaped base; a plurality of limiting sliding grooves are formed in the left end and the right end of the bottom wall of the U-shaped base at equal intervals; limiting sliding blocks are arranged in the limiting sliding grooves; first rotating pieces are arranged on the upper surfaces of the limiting sliding blocks; an arc-shaped oil pipe supporting plate is arranged above the U-shaped base; the oil pipe body comprises an outer protection pipe and an inner oil conveying pipe; the outer protection pipe is placed on the arc-shaped oil pipe supporting plate; and the outer protection pipe is fixedly arranged through an arc-shaped clamping strip. When the oil pipe body is impacted by the outside, the impact resistance of the oil pipe body is higher, so that deformation or damage caused by the fact that the oil pipe body is impacted by the outside is effectively avoided; and the oil pipe is convenient to operate, excellent in sealing effect and high in practicability when being connected.

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
