摘要
气体钻井新技术对传统录井的出口工程参数、常规地质录井、气测录井会产生重大影响,其主要表现在信息被弱化,造成岩屑辨别困难,给岩性定名及地层分层、地质工程预报、油气水显示的发现等带来诸多困难。为此,研究了工程录井的典型特征,常规地质录井迟到时间的确定、岩屑捞取方法、岩屑鉴别方法、气体钻井中常见的岩屑识别特征和荧光录井方法措施,以及气测录井的气体采集、分析和油气水监测等技术,总结出与气体钻井相配套的录井技术。通过四川地区20多口井气体钻井录井的检验,证实该配套技术能够达到取全、取准录井资料的目的。还提出了改变目前录井信息采集方法,发展随钻录井技术的展望。
New gas drilling techniques have significant influences on the outlet engineering parameters of traditional logging, conventional geologic logging and mud logging. In particular, they weaken useful information and complicate cutting discrimination, making it more difficult to determine lithology, to divide layers, to make geologic engineering prediction, and to recognize oil/gas shows. This paper studies the typical characteristics of engineering logging, determination of lag time of conventional geologic logging, methods of cutting sampling and discrimination, common cutting features and fluorologging techniques for gas drilling, as well as gas sampling and analysis and monitoring of oil, gas and water during mud logging. It presents a set of logging techniques that are adapted to gas drilling. Their application to over 20 gas wells in Sichuan Basin shows that the logging data are complete and accurate. It also presents proposals for improving current acquisition methods of logging information and developing logging while drilling techniques.
