Classification and Evaluation Criteria of Oil Shale Reservoir Logging in the Second Section of Liushagang Formation in Weixinan Depression
In order to clarify the exploration and development potential of the oil shale in the second section of Li-ushagang 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 forma-tion 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.
