Abstract


In this paper, Taiyuan group for Yulin - ZIZHOU area of ??Upper Paleozoic Shanxi group the stone box group and Shiqianfeng of containing gas segment 120 fluid inclusion samples carried out a detailed study to test different diagenetic stage authigenic minerals in fluid inclusions homogenization temperature, freezing temperatures and calculated parameters such as salinity, density and fluid potential. On this basis, determine natural gas accumulation, analysis of the gas main gathering area. Inclusions under the microscope petrography host mineral quartz, quartz grains of overgrowths and healed fractures are output. The smaller individuals inclusions, shape round and oval. Due to the different types, colors, colorless, transparent, brown, dark gray and dark brown. Vertical from Taiyuan group to the the hydrocarbons Xiashihezi inclusions abundance decreases the individual gradually smaller; gas-liquid ratio gradually decreases from south to north on the plane containing the gaseous hydrocarbon inclusions. According to its phase state component layers of the fluid inclusions in the study area is divided into the brine inclusions containing the gaseous hydrocarbons brine inclusions, gaseous hydrocarbon inclusions with daughter crystals of halite brine inclusions and CO2 three-phase inclusions five type, which contains the majority of the gaseous hydrocarbon inclusions content, indicating the higher the degree of evolution of the area of ??oil and gas. By contrast gaseous hydrocarbon inclusions and gas reservoirs of the different layers within the methane carbon isotope analysis of the composition of the inclusions in the study area, trend analysis found, Taiyuan, Shanxi, and the box in paragraph 8 of gaseous hydrocarbon inclusions methane carbon isotope relatively light, overall heavier carbon isotopes of methane gas reservoir today. 8 member, Shanxi and Taiyuan group increases gradually from north to south the wrapped body CH4 component content, indicating that a higher degree of thermal evolution of the south of the study area. Comprehensive analysis of the gas reservoir today is a result of cumulative gas gathering, but remains dynamic fractionation process. Using fluid inclusions temperature combined with burial history to draw the various layers of the study area oil and gas charging period and time. Taiyuan group of two oil and gas filling: Phase ago 200-180 Ma, Early Jurassic; Phase II 160-120Ma, namely J22-K12 Mountain 23 gas filling of the reservoir has experienced two hydrocarbon gases the first phase of BP 200 170 Ma that J11-J21; 160-115Ma in the second phase, J22-K12. Paragraph 8 gas reservoir Xiashihezi box also experienced two hydrocarbon gases filling first dating 190-175Ma, J12-J2; Phase II 155-125Ma J3-K12. Are the second phase of the three layers of gas filling for the main filling period. $ 15 segment Shiqianfeng gas reservoir experienced a filling, filling 170-140 Ma for the Late Jurassic. The recovery the ancient fluid potential draw: fluid migration within the basin to the northeast - southwest to the main, basically from the southwest to the center and northeast of Transportation. Basin, southwest in Yanshan final for a relatively high potential area surrounding the ancient fluid potential value is gradually reduced, especially north Oriental to ancient fluid potential gradient, the main directions of hydrocarbon migration zone.
