Characteristics and Accumulation Significance of the Pathway Systems in Lower Palaeozoic Carbonate, Tazhong Area
摘要
Abstract
This paper analyzes the effect and characteristics of such pathway systems as faults, cracks, unconformity and karst in Lower Palaeozoic carbonate in Tazhong area. The bridging and interconnection of faults with the source rocks and reservoir beds led to the vertical migration of oil and gas. While the multistage regional unconformity surfaces, network systems of karstified fissures and caves made it feasible for oil and gas to migrate laterally. All the factors above constitute the hydrocarbon pathway systems and control the accumulation and distribution of oil and gas in Tazhong area. Large scale strike-slip fault systems trending NE control the secondary accumulation and distribution of oil and gas in the area. These factors cause oil and gas to accumulate along a belt and enrich in a block.关键词
