THE SOURCES OF GAS POOLS IN YINGHUANG FORMATION AND ITS EXPLORATORY IMPLICATION IN THE YINGGEHAI BASIN

The question about the source of shallow gas accumulation with normal pressure in Yinghuang formation is a key to gas exploration and geological research. Based on geological and geochemical data,teh hydrocabon sources and accumulation conditions were analysed in detail. Conclusively,the shollow gas pools with normal pressure mostly sourced the rocks of the middle and lower Yinghuang formation.
