气测录井资料是油气勘探开发研究中广泛用到的基础资料,而钻井现场录取的气测资料受到钻井参数、录井监测、真假异常等诸多方面的影响。很多地质研究工作要在未完钻之前完成,在没有测井、测试资料的情况下,而且当前PDC钻头的广泛应用,岩屑录井资料代表性差、误差大,致使气测录井资料成为实钻中主要的储层评价依据。因此,在地质研究中,了解影响气测录井资料真实性的各种因素,准确识别真实的气测录井资料,对提高油气勘探效率有十分重要的作用。
Gas logging data is widely used in oil and gas exploration and development research, and gas data collected on the drilling site are affected by drilling parameters, well monitoring, abnormality of true and false, and so on. Many geological research work should be completed before the completion of drilling. In the absence of well logging and testing data, and the wide application of current PDC bits, logging data of shale logging are poorly represented and have large errors. As a result, gas logging data become real drilling The main reservoir evaluation basis. Therefore, in geological research, understanding various factors that affect the authenticity of gas logging data and accurately identifying the real gas logging data are very important to improve the exploration efficiency of oil and gas.
