摘要

According to the geological characteristics of deep formation in Qingshen gas field, research was made on systematic technologies for deep exploration drilling. In recent 2 years, through the tests on systematic technologies for deep drilling with higher ROP, underbalanced drilling, nitrogen filled drilling; air and air filled drilling, important technical breakthrough was made with penetration rate greatly increased, and gas layer was found and protected in time, which has played a key role in the demonstration of reservoir of 1.0×10¹²  m³ natural gas in Songbei district.
