Abstract: The technique, equipment and criterion of well control in natural gas drilling have been developed to relative perfect level in 1990 years, the most outward harvest is that the accident of catastrophic blowout had never taken place in Sichuan basin（the production base of natural gas）in almost twenty years. However, along with the exploratory development of high pressure and high production natural gas reservoir, the application and dissemination of horizontal well and underbalance drilling, the current well control technique cannot meet completely the requirement of the new condition, and confronts with many challenges. Therefore, the directions of the innovations and developments of well control technique in natural gas drilling are given: first, the theory of well control should been improved, the advanced and practicable software of wellbore pressure profile computation should been developed; second, the matching level of well control equipments should been enhanced further, the their reliability should been raised; third, in order to discover overflow just in time, the apparatus such that fluid level in wellbore is measured automatically should been developed; last, closed, pressurizable circulation system should been established to achieve at managed pressure drilling. The ultimate aim of well control technique is developed from preventing blowout to formation damage control, protecting resource and environment, improving drill speed and decreasing cost cutting of drilling.
