摘要
d=EnChDivSummary name="EnDivSummary">The 2nd member of Tertiary Xujiahe Formation is characterized by huge natural gas resource, serious densification degree of reservoir, complex pooling mechanism. Gas reservoir is mainly of lithology subtle trap, it is difficult for seismic exploration and beneficial target prediction. Therefore, by analyzing sequence stratigraphic framework, seismic facies and favorable sedimentary facies, combing with fracture prediction technology, the hydrocarbon bearing belt was fine described. The result shows that the mouth bar and underlying frontier sandbodies top of the 2nd member of Tertiary Xujiahe Formation in Xinchang area and Dayi area are favorable hydrocarbon accumulation belt, which is the favorable exploration target. In terms of prediction result, one exploration well was deployed in Deyang Syncline.
