Abstract:

Based on the high resolution seismic data，many reservoir-forming models were established by utilizing geology, well log and well-drilling data and by analyzing reservoir-forming mechanism and model of lithological reservoir.While identifying the exploration difficult points of lithological reservoir, the solutions were presented too. Many advanced technologies up-to-date were used to conduct reservoir prediction and bar sandbody spatial distribution of the third member of Shahejie Formation on the basis of high resolution seismic data interpretation. Significant effect was obtained in the actual application of the Kouxi area，and the application of matching geophysical technologies would provide referential experience for the subtle reservoir exploration in the future.
