摘要
与电缆测井相比，尽管随钻测井具有诸多优点，但仍然要受其环境因素的影响。本文针对随钻密度测井受偏心等环境因素的影响，建立了圆形、椭圆形和槽型三种间隙校正模型，进而实现随钻密度测井资料的偏心影响校正。校正结果与经过偏心影响校正的电缆密度测井相比，其相对误差小于5％，达到了随钻测井环境影响校正指标的要求。
Comparing with wireline logging,although LWD has many advantages,it is still affected by the environmental factors.Aiming at the envi- ronmental factors of eccentric effect for LWD density logging,three kinds of interval correction models of circle,ellipse and trough are es- tablished to realize the eccentric effect correction.Comparing the correction result with that of wireline density logging,its relative error is less than 5%,which can meet the index requirement for LWD environmental effect correction.
