摘要
Paleogene in Chaluhe Depression, Yitong Basin is graben-like fault basin sedimentary, and the reservoir is lacustrine subaqueous fan of gravity flow origin and characterized by proximal provenance, fast accumulation rate, various lithology of sandstones. In order to evaluate hydrocarbon reservoir via conventional log data, and promote the success of log interpretation, the authors establish a suit of interpretation model for the lithology, physical property and hydrocarbon-bearing characteristics in this region, by the method of comprehensive analysis of reservoir rock types, physical character and hydrocarbon-bearing nature, integrating with the test result of production well. The cross plots of different log interpretation parameters can remarkably distinguish gas lay, oil lay, gas and water lay, oil and water layer, water layer,and dry layer with different hydrocarbon characteristics.
