摘要
从密度测井的基本原理出发,基于几何因子理论建立了密度测井校正模型。主要思路是将球形探测区域进行划分和优化各部分的权重。实际应用表明,处理后的测井曲线基本消除了围岩对薄层测井曲线的影响,相对于原曲线能更清晰地反映地层情况。
Constructed is a geometric factor model for correcting density log, in which the region affecting density measurement is considered as a spheroid centered at the sampling point, and thespherical segment of two bases containing the sphere center denotes the objective layer, and sev - eral spherical segments over/under the center one denote the up/down surrounding beds. It is believed that the corrected results of practice density logging curvesin this way are more accurate.
