Product Description

Oil pipe is mainly used for drilling oil and gas wells and transporting oil and gas. It includes oil drill pipe, oil casing and pumping pipe. Oil drill pipe is mainly used to connect drill collar and drill bit and transmit drilling power. Oil casing is mainly used to support the well wall during drilling and after completion to ensure the normal operation of the drilling process and the entire oil well after completion. Pumping pipe mainly transports oil and gas from the bottom of the oil well to the ground.

Packaging: Domestic casing should be tied with steel wire or steel belt. The exposed part of each casing and coupling thread should be screwed with a protective ring to protect the thread

Advantages

During the drilling process, the oil casing is lowered into the wellbore and forms a whole with the cementing cement, thereby stabilizing the wellbore structure, ensuring the stability of the wellbore, preventing the wellbore from collapsing, and ensuring the circulation of drilling mud for drilling and mining.

In addition, the oil casing can also isolate the strata, avoid cross-contamination between different strata, and protect groundwater resources.

Application

It is used for drilling oil and gas wells and the transportation of oil and gas.

Oil casing is a large-diameter pipe that plays the role of fixing the wall or wellbore of oil and natural gas wells. It is mainly used to support the wellbore wall during drilling and after completion to ensure the progress of the drilling process and the normal operation of the entire oil well after completion.

Oil drill pipe is mainly used to connect the drill collar and the drill bit and transmit drilling power.

The pumping pipe mainly transports oil and gas from the bottom of the oil well to the gr
