摘　　要：位于塔里木盆地西南部的柯克亚气田历经30余年的勘探、开发,其测井资料不能形成统一的数据标准,在分析评价中不具有一致性和可对比性。为此,对不同时期的常规测井资料特征进行了深入分析研究,从单井曲线深度匹配、测井曲线单位统一、自然电位校正、自然伽马井间偏移校正、声波时差校正和电阻率确定等方面入手,建立了该气田测井资料标准化的方法,并通过对实际井资料的处理,实现了老探区不同时期常规测井资料的规范和统一,为气田后续测井综合评价及研究提供了精确的基础资料。For lack of a unified data standard,neither consistency nor comparability can be found in the cumulative log data collected in the Kekeya Gas Field,Southwest Tarim Basin,which has been explored and exploited over the past three decades.In view of this,a thorough analysis was performed of the conventional wireline log data acquired at different periods and methods of standardizing the log data were developed in the respects of single-well curve depth matching,unification of curve units,spontaneous potential correction(SP),interwell GR migration correction,interval transit time correction(DT or AC),resistivity determination(RT),etc.With these methods,the old well logging data have been processed and thus the conventional log data at different periods of the mature exploration zones have become unified and standardized,providing a sound basis for future integrated logging evaluation and research in this field.
