储层临界物性对岩性圈闭油气成藏的意义——以准噶尔盆地东部白家海凸起侏罗系储层为例
Control of critical physical properties or reservoir to the hydrocarbon accumulation in lithological traps; taking Jurassic of Baijiahai uplift in the eastern Junggar Basin as an example
摘要
Abstract
There developed litliological hydrocarbon reservoirs in Jurassic of Baijiahai uplift in the eastern Junggar Basin. There is difference in the forming mechanism of different lithological traps in the same zone of the basin. According to the characteristics of multiple-factor controlling oil and main-factor controlling reservoir formation of lithologic traps,the critical oil-bearing porosity and permeability of Xishanyao Formation reservoir of Jurassic in Cai-43 wellblock were studied by porosity-permeability intersection and oil-bearing occurrence analysis. It is found that the critical oil-bearing porosity and permeability of the reservoir under conventional laboratory conditions are about 11.5% and 0.1 × 10-3 μm2. But the critical oil-bearing porosity and permeability under surface conditions are different from those under formation conditions. They vary with the buried depth of reservoir. The critical oil-bearing porosily and permeability of the reservoir under formation conditions are presented by pressure correction. According to the analyses of effective oil-bearing porosity, effective oil-bearing permeability and advantage flow coefficient, it is found that the critical physical parameters have control effects on the hydrocarbon accumulation of Jurassic in Baijiahai uplift.关键词
