摘　　要：针对近年来在松辽盆地浅层储层砂体刻画研究中,测井资料存在曲线间差异大,测井数据不统一,造成储层砂体预测无法达到较高精度要求等问题,结合实际地质资料,以松辽盆地西斜坡塔34区块姚家组二、三段为研究主体,优选基于拟合趋势面的测井曲线标准化处理方法,并应用该技术进行测井曲线处理后的反演技术分析。研究结果表明,针对塔34区块所选取的四次标准化系数对测井曲线刻画效果最为准确,岩芯孔隙度与处理后曲线的相关系数和反演预测砂岩及有效砂岩精确度较处理之前明显提高;基于趋势面的曲线处理方法,可以有效地解决由于岩性发育所造成的各种区域地质问题,使其与实际地质信息相统一。本研究为后期地震反演工作提供了高度一致性的测井数据。In recent years,for the logging information in shallow reservoir sand characterization study of Songliao Basin,there exist some issues,e.g.,large difference exists between curves,logging data are not unified,reservoir sand body prediction can not meet the requirements of higher accuracy.Logging curve processing can effectively eliminate the systematic error of the data and is the critical basic work to improve the knowledge of reservoir sand body,reservoir prediction and hydrocarbon accumulation precision in new description.Combined with the practical situation of geological data,the paper optimized logging curve processing methods by fitting the trend surface development of Yao No.2and No.3section in Ta34 block.Inversion analysis with four sets of standardization coefficients gives the most accurate characterization of logging curves in Ta34 block.This methods could effectively contain various regional geological effects caused by the development of rock in this area,and provide highly consistent logging data to improve development precision.
