In some areas of Changning shale gas play, the surface well leakage problem seriously affects the efficient exploration and development of shale gas resources in this area due to the complex surface topography, rich groundwater resources, well developed fractures and karst caves in the surface layer, and low formation pressure coefficient. At present,there are no better drilling technology measures except gas drilling and clean water drilling. But these two methods have some limitations because the gas drilling technology can not work well in water producing formation and there exist high risk of sticking in clean water drilling. Dual drill pipe gas lift reverse circulation drilling technology is an effective low-pressure and underbalanced pressure drilling technology, which has been applied in water well, geothermal well and other drilling applications. However, this technology needs special matching tools such as gas swivel, dual drill pipe and gas-water mixer. And it has complex process and cost high. Therefore, on the base of dual drill pipe gas lift reverse circulation drilling technology, a new technology of aeration reverse circulation drilling with conventional drill pipe is designed and field test is carried out to solve the problem of serious lost circulation in Changning shale gas surface drilling. The total footage is 241 m, and the loss of drilling fluid is 83 . 6% less than that of adjacent wells in the same well section. The research results provide a new technical measure to solve the serious lost circulation problem in Changning shale gas surface sections, providing a reference for solving other drilling problems in low-pressure and leaky formations.
