Recently, Dagang Oilfield Group Co., Ltd. independently developed the "Fast-free wellhead installation for drilling rigs" project, which won the national utility-type patent, marking the new cementing technology service of Dagang Oilfield Group Company to a new level.
For a long time, the cementing industry has generally adopted the method of cementing the cementing tools on the joint surface of the joint section. With the continuous development of drilling technology in Dagang Oilfield, the use of batch drilling to speed up petroleum engineering is imminent. In order to shorten the cementing cycle and reduce the cementing construction intensity, Dagang Oilfield Group Cementing Technology Service Co., Ltd. has started the project “Research on Integrated Technology of Ending Island without Drilling Cementing†since the end of 2006. After nearly one year of research and implementation, the project has been successfully tackled, and its supporting project “Fast Wellhead Device for No-Drilling Cementing†has obtained national practical technical patents.
"Fast-filled wellhead device for drilling-free cementing" successfully solved the need of manual tightening and raising short joints and cementing cement heads during cementing construction. It has high labor intensity, difficult to buckle, extremely easy to damage the thread buckle, and the degree of tightening is also It is difficult to control, the pressure bearing capacity of the thread can not be guaranteed, and the construction safety hazard is large, which provides technical support for ensuring the safety of cementing construction and shortening the drilling cycle.
From the beginning of 2007 to the present, "Tiandao No-drilling Cementing Comprehensive Supporting Technology Research" has been successfully implemented in the Bohai No. 1 artificial island, and a total of 19 wells have been cemented, which has proved the advanced and effective technical solutions. feasibility.
