The API oil casing is mainly used for the drilling of oil and gas wells and the transportation of oil and gas. It contains oil drilling pipes, API oil casing, and oil extraction pipes. The oil drill pipe is mainly used to connect drill collars and drill bits and transmit drilling power. The API oil casing is mainly used to support the wellbore during and after drilling to ensure the progress of the drilling process and the normal operation of the entire well after completion. The oil pumping pipe transports the oil and gas from the bottom of the well to the ground.
The API oil casing is the lifeline that keeps the well running. Because of the different geological conditions, the downhole stress conditions are complex, and the pull, pressure, bending, and torsional stress induction effects are effective on the pipe body, which puts a high demand on the quality of the casing itself. Once the casing itself is damaged for some reason, the entire well can be reduced in production, or even become obsolete.
The API oil casing is a large-diameter pipe that serves to fix oil and gas well walls or well bores. The casing is pierced into the wellbore and cemented to prevent the wellbore from falling from the strata and wellbore and to ensure drilling mud circulation for drilling and excavation.
API oil casing steel grade: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150 and so on. Casing end machining methods: short round thread, long round thread, trapezoidal thread, special buckle, etc. The drilling for oil wells is mainly used to support the wellbore during and after completion of the drilling process to ensure the progress of the drilling process and the normal operation of the entire well after completion.
