摘要
Air drilling is an important drilling technology to effectively develope coalbed methane.Research was conducted on rock strata features,hydrogeololgy condition,water saturation character and foam drilling mud design. And according to the formation characteristics,the matching technology suitable for air drilling was designed in Liulin district.During the construction of 7 coalbed methane wells in liulin district,drilling period was shortened by 50%,reservoir was protected effectively,and the production of vertical wells and horizontal well reached 1 000 cubic meters and 15 000 cubic meters with great applicaton prospect.
