The petroleum industry is a type of occupation that uses the oil casing pipe extensively, and it plays a special role in the petroleum industry. The ineffective loss of oil casing pipe is immeasurable, and its safety performance, stability and service life play an important role in the petroleum industry.
Considering its large loss and relatively high cost, oil casing pipe has the potential to save expenses and reduce costs. The loss of oil well pipes can be calculated according to the cost of drilling footage in the current year. According to the actual situation, 62kg of oil pipeline is required for every 1 meter drilled, including 48kg of casing, 10kg of oil pipeline, drill pipe of 3kg, and drill collar of 0.5kg.
The inner and outer surface layers of the casing pipe for oil well drilling cannot have folds, hairline cracks, fissures, cracks, folds and incrustation. These blemishes should be completely cleaned up, and the depth of the cleaning should not be higher than 12.5% of the nominal wall thickness. The mechanical and regional environmental conditions of the oil casing pipe have an important influence on the application of advanced technology in the petroleum industry and the continuous improvement of efficiency.
The oil casing pipe is mainly used for the drilling of oil and gas wells and the transportation of oil and gas. It mainly includes oil drill pipes, oil casing pipes, and oil pumping pipes.
The casing pipe for oil well drilling is mainly used to connect drill collars and drill bits and transmit drilling power. The oil casing pipe is mainly used to support the well wall during drilling and after completion to ensure the progress of the drilling process and the normal operation of the entire oil well. The oil pumping pipe is mainly used to transfer the oil and gas from the bottom of the oil well to the ground.
