The API oil casing is a large-diameter pipe that functions as a fixed oil and gas well wall or wellbore. The casing is inserted into the wellbore and cemented to prevent the wellbore from separating the rock formation and the wellbore collapse, and to ensure that the drilling mud is circulated for drilling and exploration.
The oil grade of the oil casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150 and so on. Tubular end machining form: Short round thread, long round thread, partial trapezoidal thread, special buckle, etc. Drilling for oil wells is mainly used to support the wellbore during and after drilling to ensure the normal operation of the entire well after the drilling process is completed.
