涠西南凹陷流2段油页岩储层测井分类评价标准

Classification and Evaluation Criteria of Oil Shale Reservoir Logging in theSecond Section of Liushagang Formation in Weixinan Depression

为进一步明确涠西南凹陷流2段油页岩的勘探开发潜力,在大量调研的基础上,结合岩心实验分析、测井解释等数据开展储层测井分类评价标准研究。研究认为,涠西南凹陷流2段油页岩在生油能力、储集性能、可压性等方面与松辽盆地古龙青1段油页岩具有极大的相似性。据此结论,构建了流2段油页岩储层分类评价标准,并按照此标准对WY-1井I类储层作出综合解释。

In order to clarify the exploration and development potential of the oil shale in the second section of Liushagang formation in the Weixinan depression,a study on classification and evaluation criteria of oil shale reservoir logging was carried out based on a large number of investigations and combined with the data of core experimental analysis,log interpretation,etc.Research suggests that the oil shale in the second section of the Liushagang formation in the Weixinan sag has strong similarities with the shale oil in the first section of the Gulongqing formation in the Songliao basin in terms of oil generation capacity,reservoir performance,and compressibility.Based on this,the classification and evaluation criteria of oil shale reservoirs in the second section of the Liushagang formation has been constructed.According to this criteria,the class I reservoirs in well WY-1 are comprehensively interpreted.
