Technical research on improving efifciency of gas drilling in Qingshen Gas Field
摘要
Abstract
The drilling practice of Qingshen Gas Field shows that gas drilling can improve the efifciency of drilling speed, but there is much mud shale in gas drilling application interval. Therefore, once the formation water lfows out from the formation, the complex problems, such as pipe sticking, likely occur, which have great effect on drilling, logging, and cementing, etc. This paper analyzes the factors that affect the efifciency of gas drilling and rebuild water forecasting model for formation water overlfowing during gas drilling according to previous drilling experience. Based on the theoretical analysis, the researchers have improved related equipment and tech-nology, and formed a series of matched technologies. The application of six wells shows through the improvement of related technology, complex incidents have been prevented efifciently, the quality of well has been guaranteed as well as the overall beneift of gas drilling has been improved.关键词
