摘　　要：空气钻井是欠平衡钻井的一种,是目前钻速最快的钻井作业方式之一,但空气钻井技术的主要障碍之一是地层出水。介绍确定出水地层的2类方法:一是利用已有的测井资料预测出水地层;二是在钻井过程中,通过钻井监测判断出水地层;并分析各种方法的不足之处。建议应该针对空气钻井中的地层出水问题,利用测井资料确定出水地层并结合地层参数,判断出水地层,并建立空气钻井中出水地层出水量的计算模型,指导空气钻井作业。Air drilling is a drilling technology of underbalanced drilling and one of the fastest drilling technologies.Air drilling is widely used both home and abroad,while the primary challenge of air drilling is formation water production.Two methods of water formation decision are introduced in this paper.One is the judgment method of the water layer by using logging data,the other is the judgment method of the water layer with drilling monitoring.The shortcomings of various methods are analyzed.For the formation water production of air drilling,the water formation should be determined by using logging data and combined with the formation parameters.The model of formation water production should be obtained and the research will play an important role in application of air drilling with formation water production.
