摘　　要：目前,低渗、致密油气藏已成为中国勘探开发的重点方向,但由于此类油气藏一般埋藏较深、储层条件复杂,因此勘探开发难度较大。目前,氮气钻完井技术是开发此类油藏最有效的手段之一,同时也是目前能够真正实现储层“零污染”的钻完井技术之一,能够及时发现油气层,获得储层的原始产能,是实现高产和稳产的有效手段。此外,它能大幅提高钻井效率,降低井漏对钻井作业的影响。At present,low-permeability and tight oil and gas reservoirs have become a key direction for exploration and development in China.However,due to their generally deep burial and complex reservoir conditions,exploration and development are difficult.At present,nitrogen drilling and completion technology is one of the most effective means to develop such reservoirs,and it is also one of the drilling and completion technologies that can truly achieve zero pollution in reservoirs.It can timely discover oil and gas reservoirs,obtain the original production capacity of reservoirs,and is an effective means to achieve high and stable production;In addition,it can significantly improve drilling efficiency and reduce the impact of well leakage on drilling operations.
