摘要
用测井预测烃源岩有机质丰度,克服了常规岩样分析中岩心资料连续性差,取心成本高的问题。通过对研究区多井各个深度段烃源岩有机质丰度的研究,可以了解烃源岩有机质丰度在平面上、纵向上的分布规律。以松辽盆地齐家地区青山口组为例,依据测井资料,采用ΔLgR法计算烃源岩总有机碳含量(TOC),其计算TOC的结果基本上与岩样分析资料吻合。
The prediction of source rock organic matter abundance through well logging has overcome issues of poor continuity of rock core data from conventional rock sample analysis and high coring cost. Through the study on source rock organic matter abundance of multi - borehole different depth segments can learn source rock organic matter distribution on the plane and longitudinal pattern. Taking the Qingshankou Formation in Qijia area, Songliao Basin as example, based on logging data, through △LgR method computed source rock TOC content; the result is basically identical to rock sample analyzed data.
