Oil delivery pipe

Abstract

Provided is an oil delivery pipe. An erosion resistant layer is arranged on the inner wall of the oil pipe, and the thickness of the erosion resistant layer is 20-24mm. According to the oil pipe, oil pipe scaling can be delayed, the oil pipe corrosion perforation speed is reduced, the service life of the oil pipe is prolonged, and oil extraction cost of an oil field is reduced.

Description

technical field

[0001] The invention relates to an oil delivery pipe. Background technique

[0002] At present, in order to increase oil production, composite polymers are generally used as oil displacement agents. These oil displacement methods all use chemical agent oil recovery technology, and the use of chemical agent oil displacement can easily cause scaling, and alkali reacts with sandstone formations to produce soluble silicate. The salt mixes with other formation water containing calcium and magnesium ions and higher salinity reaching the oil well to cause scaling. At the same time, due to the incompatibility of oil production water and the change of water quality conditions, scales on the surface of the formation and scales formed by corrosion products can block the oil well strings in a short period of time. At present, the anti-scaling and anti-corrosion layer applied to oil pipes generally has a thickness of 250-300mm, and the anti-scaling and anti-corrosion per...

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] Referring to the accompanying drawings, an oil pipeline, including an oil pipeline, is characterized in that: an HDPE geomembrane anticorrosion layer is provided on the inner wall of the oil pipeline. The thickness of the anti-corrosion layer (2) is 20-24mm.

[0011] HDPE geomembrane has good heat resistance and cold resistance, and its operating environment temperature is high temperature 110 ℃; low temperature -70 ℃, HDPE geomembrane has good chemical stability, and it is good to be able to resist strong acid, alkali and oil corrosion It is an anti-corrosion material, and it has good decorative and anti-corrosion properties after curing. It has the characteristics of preventing scaling and corrosion protection for oil pipes, especially for the corrosion of oil pipes caused by chemical agent ASP flooding and the scale caused by scale on oil pipes. It has strong ant...
