摘　　要：气体钻井技术是一项系统工程,是随着欠平衡钻井技术的发展应运而生的,它是欠平衡钻井技术的提高和完善,是钻井工程的进步。采用气体钻井技术主要解决了提高机械钻速、复杂地质条件下的井漏等重大钻井难题,并成为发现低压低产储层、保护油气层、提高油气产量的重要手段。介绍了国内外钻井用气体型流体的分类、应用情况,并对不同钻井条件下气体类型的选择及使用原则进行了研讨。As a system engineering,gas drilling emerged with the development of under balanced drilling technology.Gas drilling successfully solved the low ROP and mud losses in complex geological formations,and also played an important role in finding low-pressure low-productivity gas reservoirs,preventing reservoirs from being damaged,and enhancing oil and gas production.The selection of fluid and the conversion from one to another fluid are the key in gas drilling.This paper introduces the classification of gases in gas drilling in the industry and the application of gas drilling.The selection of fluids in different drilling conditions,and the principle of application are discussed.
