摘要
以通过钻井液实时连续检测烃类气体为目的的气测录井在油气勘探开发过程中一直起着其它录井手段无法替代的作用。该文通过对气测录井检测分析手段以及钻井过程中一些尚不可控条件的分析,阐述了影响气测录井发现和评价油气层准确性的几个方面的主要因素,分别为钻井工程、脱气器、仪器标定及取值方式以及气测后效对气测录井的影响,结合因素分析,探讨了消除部分影响因素的方法。为加强气测录井技术深入研究,使其真正实现从定性向定量发展,提出了主攻方向。
Gas-logging which aims at real-time and continously detecting hydrocarbon in drilling fluid plays an unreplacable role with the other logging means in oil gas exploration and development .By analysing the gas logging detecting means and some uncontrollable conditions during drilling,the paper expounded main factors from a few aspects of influencing the accuracy of discovering and evaluating oil gas zones,discussed the affecting factors of drilling engineering,degasser,instrument calibration,value-obtaining way and the aftereffect gas in gas logging,and described how to eliminate affecting factors partly.
