Gas reservoir type and reservoir-forming rule of Huagou gas field;

Based on the study of the reservoir-forming rule, it is considered that the degree, of prospecting is still very low.

Based on the analysis of exploration wells information,seismic data and typical reservoir,the development features of unconformity structure,action of the unconformity to reservoir forming,and reservoir-forming rules and fine description method of unconformity traps in Jiyang Depression were researched.

An analysis carried out on the reservoiring pattern of natural gas in Shiwu and Changlin fault depressions suggests that the gas reservoiring be controlled by the distribution and evolution of source rocks and the configuration between large-scale structure belt and the sedimentary facies and their preservation condit.
