摘　　要：焉耆盆地地质条件复杂，开发速度上的快，对钻井速度要求较高。在广大技术干部的辛勤工作中，积累了许多宝贵经验，创造了一套适合焉耆盆地地质特征的钻井工艺技术措施，使平均机械钻速由1994年的3．42m／h提高到1997年的5.94m／h，提高了42．42％。本文旨在对焉耆盆地的一些经验教训进行总结，以利于进一步推广和提高。所列技术措施对该地区的钻井施工具有一定指导意义，类似地层也可供鉴．同时重点突出了安全快速钻进的技术参数及技术措施．The geologic conditions in Yanqi Basin are complexand the drilling progress has to meet the requirements ofhigh development rate. Many valuable experience aregained and a series of drilling technologies that aresuitable for the geologic conditions in Yanqi Basin aredeveloped in drilling practiee.The average penetration rateincreases from 3.42m/h in 1994 to 5.94m/h in 1997, a42.42% improvement. This pape sums up the experienceand lessons gained in Yanqi Basin and is focused on thetechnical parameters and measures for safely and rapidlydrilling.The technical measures outlined in this paper havecertain directive significances for drilling operation in thisarea and also can be used as references in similal areas.
