摘要
Anatomy of the Qiudong sag south slope and north piedmont thrust belt known tight sandstone gas reservoirs,compared to the Shengbei sag tight sandstone,gas reservoirs have the following characteristics: 1) coal strata of large quantities of hydrocarbon generation provided adequate gas for the formation of tight sandstone gas reservoirs;2) source rocks and reservoir were interbedded and its close contact is favorable to the accumulation of tight sandstone gas source and 3) gas reservoir is characteristic of high moisture content,low pressure.Reservoir heterogeneity,compactness,and good sealing conditions are the geological factors that affect the area of tight sandstone gas reservoir.The southern slopes of the District and the central uplift,of the Shengbei sag,the source rock and reservoir configuration favorable conditions,is the favorable region.
