低渗透岩性油藏含油性与富集区测井评价研究

Evaluation of oil bearing property and logging of enrichment area in low permeability lithologic reservoir

本文以鄂尔多斯盆地姬源地区延长组长油层组为研究对象,建立了测井识别和定量评价低渗透油气储层的方法,分析了低渗透岩性油藏含油饱和度分布规律,探讨了测井快速产能预测和富集区评价方法,优选了有利勘探开发目标。

The Chang reservoir in the Yanchang formation of Erdos Jiyuan basin is taken as the research object to establish amethod of logging identification and quantitative evaluation in the low permeability oil and gas reservoir.Also,the paper analyses theoil saturation distribution of low permeability oil and gas reservoir,and discusses the rapid productivity prediction method in loggingand the evaluation method of the enrichment area,and optimizes the favorable exploration target.
