摘要
Dongpu sag is of the superior geological conditions for forming deep gas pools, including two sets of premium source rocks, variety of sand bodies, well developed porosity and thick halite and mudstone as cap rocks. This paper presents the model for deep gas migration and accumulation in Dongpu sag by analyzing the histories of hydrocarbon generation, filling and injection, tectonic evolution and hydrocarbon migration and accumulation, using dynamic prediction method for oil-gas accumulation.
