摘要
According to the latest geologic,drilling and logging data from the gas pay zone,the reservoir prediction is performed in the Upper Triassic Xujiahe Formation of the Guang’an area,middle Sichuan Basin. From which such parameters as thickness,porosity,storage factor,etc.are obtained and the distribution range of hydrocarbon favorable areas is also delineated.The following conclusions are drawn:1) the relatively well-developed zones are mainly distributed in the area between Miao-4 well and Hechuan-151 well,and the reservoirs with thickness of more than 10 m have an area of 173.4 km2; 2) in general,favorable areas for hydrocarbon detection in this study area are distributed in the NW or EW direction with an area of 516.2 km2;they are mainly distributed in strips or belts in the area between Hechuan and Baimiao.On this basis,the further favorable zones for natural gas exploration are pointed out herein in the paper.
