Evaluation of Natural Gas Accumulation Conditions

The regional oil and gas accumulation processes in Central Sichuan are very complex due to multiple sets of source rocks, multiple sets of plays and multiple accumulation periods. This research focused on the structural evolution and reconstructed the reservoir evolution with regional accumulation characteristics and models through single-well simulation, accumulation element analysis, hydrocarbon generation and evolution characteristics of source rocks, hydrocarbon phase behavior of reservoirs and trap analysis.
