摘要
页岩油勘探是目前大庆油田勘探开发的重要新领域。在泥页岩中进行气测异常划分,其受钻井条件的影响更为严重。为进一步提高录井现场气测资料的参考性,给实时决策提供充分依据,在参考常规储层气测异常显示划分的基础上,通过理论分析,利用现场现有数据库中的dc指数,对气测数据进行相应加权,以此校正异常幅度,进而辅助指导现场气测异常划分,提高其准确性。
Shale oil exploration is an important new field of exploration and development in Daqing Oilfield.It is more seriously affected by drilling conditions to divide gas logging anomalies in shale.In order to further improve the reference value of gas logging data on site and provide sufficient basis for real-time decision-making,on the basis of reference to the division of gas logging anomaly shows in conventional reservoirs,through theoretical analysis,using the dc index in the existing database on site,the gas logging data is weighted accordingly,so as to correct the amplitude of gas logging anomalies,and then guide the division of gas logging anomalies on site and improve the accuracy of gas logging anomaly division.
