　　Recently, the 30560 team of Liupu Drilling Branch of East China Petroleum Engineering Co., Ltd. has undertaken drilling. The Jing1 well in our company responsible for plugging service and technical support for drilling fluid has successfully drilled to 1902m.

　　Well Jingjing 1 is an undisturbed geothermal heat utilization well. It is located in Maofangbei District, Anningzhuang East Road, Qinghe, Haidian District, Beijing, with a designed well depth of 2500m. The geological structure of the well belongs to the central part of North China-the west of the Yanshan subsidence zone. The regional structure is dominated by fractures and folds. The leakage prevention and collapse resistance of the drilling fluid determines the success of the well.

　　By applying our company's new plug-while-drilling technology, it effectively blocked 216m, 241m, 340m, 500m, 1057m, 1300m, 1440m, 1900m and other leaky formations, and repaired easily collapsed formations, providing a safe and efficient drilling team for drilling A strong technical guarantee.
