At present, many oil companies are protecting oil casings and do not allow the use of wear-resistant bands. Many drilling companies have tried many methods to remove the tungsten carbide toughness of the drill pipe. During the welding process of the wear-resistant band, due to various reasons, the quality of the wear-resistant band is unqualified and needs to be rewelded. The previously adopted measure was to use a portable grinder for grinding, which was time-consuming and labor-intensive.
In order to protect the oil casing, professional technicians conducted analysis and research, and finally developed an automatic equipment for removing the wear-resistant band of the drill pipe. During the operation, only the power is turned off, the drill pipe is transferred to the drill pipe transmission line, and the transmission line is automatically started when programmed. It rotates forward, the transmission line stops after the drill pipe is in place, the cylinder automatically raises the transmission line, and the control button is fastened by the electric chuck.
Under programmable control, the switch starts to start, the switch compresses the air supply, the cooling water supply, the horizontal axial movement. Radial movement and cutting start. Under programmable control, the compressed air supply, the cooling water supply level movement, the radial movement stops and automatically resets, the transmission line reverses the drill pipe, and the cylinder automatically moves to the rear position in place.
The drill pipe is drilled out and the whole process is automatically controlled. Using this equipment will greatly improve the removal quality of the wear-resistant band of the drill pipe and reduce the labor burden of workers. Oil casing is an important equipment for oil drilling. There are also other equipment such as drill pipe, core pipe and casing, and drill collar with small-caliber oil casing.
After oil drilling and completion, the support of the wellbore ensures the entire normal operation of the well after the drilling process and after the completion. Therefore, the problem of the oil casing is solved, and the problem encountered when the wear-resistant band on the surface of the drill pipe joint is extremely defective is eliminated.
This technology is simple in operation, with high safety and automation degree, high joint efficiency, and good cleanliness after cutting. It is suitable for oil casings of various diameters, with low noise, does not pollute the environment when using oil casings, and is also very convenient to install and debug.
