Casing running tool is a new technology for running casing. We developed the more safe and effi cient internal casing running tool to break the limitation of normal running casing operation. This technology could develop all the advantages of top drive drilling, make the casing string rotating, lift and circulating the mud simultaneously, insure the casing could be running to the well bottom normally, improve the success rate, safety and effi ciency of casing running observably. It has a wide introduction value to the oil field.

Casing running tool has a new technology for running casing. For the limitation of normal running casing operation, we researched and developed this casing running tool which has advantages of safety and high-efficiency. It clamps on the coupling’s outside by internal teeth of slip. Making the casing string rotating and circulating the drilling fl uid in the same time. It can insure the casings running to the well bottom normally. It improved the success rate, safety and efficiency in running to the well bottom normally. It improved the success rate, safety and effficiency in runing casings operation. It only need four kinds of slip head, eight kinds of slip teeth to running all sizes casings. Our casing running tools are well used in Liaohe and other domestic oilfield.
