Hydrocarbon Accumulation Mechanism of Sinian Reservoir in Anpingdian-Gaoshiti Structure, Middle Sichuan Basin

The Sinian reservior in Anpingdian (安平店)-Gaoshiti (高石梯) structure, Middle Sichuan (四川) basin, is of great importance to prospect for oil and gas. This article dissects the hydrocarbon accumulation mechanism of this area on the basis of comprehensive methods of organic geochemistry, fluid inclusion, modeling of hydrocarbon generation and expulsion from source rocks, and by combining structure evolutions and analyzing the key geologic features of hydrocarbon origin and trap...
