Entirety-type casing pipe-heads are mainly used for closing the ring-shaped spaces between the surface layer casing pipe and the first & secondary technical casing pipes and between different layers of the oil layer casing pipes. The structure of this casing pipe-head is that the main body of the pipe-head is connected with the surface casing pipe with screw threads and can be directly connected with earth drilling blowout preventer. A new type of hanger shoulder is used, which could largely increase the loading capacity, enhance the safety guarantee, meet all process requirements during earth drilling, increase the standardization degree of the well head installation, shorten the well building period, reduce the working strength for the workers and increase the working efficiency.

Type:

Product Characteristics: The design is advanced, the structure is rational, the performance is excellent, the installation on-site is convenient and the appearance is simple and graceful, so that the products could satisfy the various technical requirements during the process of well drilling, could improve the standardization level of well mouth installation, could shorten the well construction period, could reduce the worker’s labor intensity, could improve the work efficiency and have favorable social benefit and economic benefit.
