摘　　要：空气钻井工艺与常规钻井工艺的不同,给录井确定油气水层的带来了难题。从空气钻井技术及其优点入手,阐述了空气钻井条件下随钻录井的基本内容:迟到时间的测算、岩性定名、油气显示级别划分以及录井资料的解释评价方法。详细介绍了空气钻井工艺及其给录井带来的困难和需要采取的技术措施,认为虽然气体钻井相对传统的钻井工艺具有较高的优越性,但是对录井资料的采集品质、岩性剖面的准确性和油气层的解释符合率都有较大影响,岩屑的采集与描述通过采用特殊装置和适当的方法都可以很好地解决,利用气测录井结合地化、定量荧光等录井技术都可以有效识别油气水层。正确及时进行异常预报,对钻井安全有举足轻重的作用.The differences between air drilling technology and conventional drilling technology brings problems to mud logging on determining water,oil and gas layers.From air drilling technology and its advantages,the authors elaborated the basic mud logging content under air drilling condition：lag time calculation,lithology naming,classification for gas and oil show and interpretation and evaluation methods for mud logging data.The author introduced the difficulties in mud logging caused by air drilling technology and technical measures to be taken in detail and thought that though air drilling has a relative superiority to conventional drilling technology,it has a great impact on acquisition quality of mud logging data,the accuracy of lithological profiles and interpretation coincidence rate of reservoirs.Cuttings collection and description can be well solved by adopting special equipment and appropriate methods,combining gas logging with geochemical technique and quantitative fluorescence logging technology also can effectively identify water,oil and gas layers.Forecasting abnormality correctly and timely plays a key role for drilling safety.
