AN ANALYSIS OF MAIN CONTROL FACTORS AND ACCUMULATION PATTERNS OF GAS RESERVOIRS IN SHANLE STRUCTURAL PROVINCE
鄯勒构造带油气成藏主控因素和成藏规律

Studies on the geological conditions and process of hydrocarbon accumulation and the formation and the evolution of the structure in Shanle structural province show that the main factors controlling hydrocarbon accumulation are the disposal of source rock, reservoir and covering strata, and the form of ancestral structure, the space time relation of trap and source rock, and faults. However faults are fundamental factor in all this factors through controlling the connectivity of source rock, trap formation and envelop oil and gas. Generalize the accumulation patterns of gas and oil, according the analysis of the control factors and the period of hydrocarbon accumulation, which is of significance to guide the petroleum prospecting efforts in Shanle structural province.
