The role of oil pipe

Take the oil and gas: After the oil and gas wells have finished and cemented, place oil tubing in the casing to extract oil and gas to the ground.

Water injection: When the underground pressure is not enough, through the oil pipe to the well water.

Steam: In the process of heavy oil thermal recovery, use a insulated oil pipe to enter the steam into the underground.

Acidification and fracturing: in the late drilling or in order to improve the production of oil and gas wells, the need for oil and gas layer of acidification and fracturing of the medium or curing, media and curing products are transported through the oil pipeline.

Casing, Tubing for Wells, Oil Pipe, Oil Pipeline

Usage: Tube for conveying gas, water, and oil in both and natural gas industries etc.

Casing: Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi.

Tubing: Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete. It is made to withstand the pressure generated from the extraction process. Tubing is manufactured in the same way as casing, except that an additional process known as “upsetting” is applied to thicken the pipes.
