主　　题：Genesis of the Sinian Solid Bitumen and its Significance for Hydrocarbon Accumulation in the Anyue Gas Field of the Sichuan Basin 

摘      要：Objective Bitumen is generally associated with oil and gas, which was originally used as an indicator of hydrocarbon reservoirs. With the progress of organic geochemical measuring and testing techniques, bitumen, especially solid bitumen sampled from reservoirs, has been proved to be closely related to the evolution of hydrocarbon reservoirs. The Sinian cores collected from the Anyue gas field contain abundant pores, vugs and fractures, which are filled with a mass of solid bitumen of two epochs and dolomite in between. This work focused on the characteristics of different generations of bitumen and the genesis, in an effort to better understand the process of the Sinian gas accumulation in the Anyue gas field.
