准噶尔盆地车排子油田火成岩双重介质储集层地质建模
|
摘要
综合利用地质、地震、测井、试井等方面的资料,在构造建模的基础上,建立了火成岩双重介质储集层的岩相、裂缝发育带、裂缝密度、裂缝孔隙度模型;同时利用地震属性作宏观约束,在构造应力、成像测井、微地震波监测、试井等分析基础上,建立了目的层不同尺度和规模的裂缝系统模型,求取了双重介质的水动力模型-渗透率模型,并进行了模型的储量计算。通过对火成岩双重介质储集层建模的研究,为车排子油田火成岩双重介质油藏有效开发奠定了基础。
Based on the geological, seismic, logging, well test data and the structural modeling, the lithofacies, fracture zone, fracture density and fracture porosity models for dual porosity reservoir of igneous rocks in Chepaizi oilfield in Junggar basin are developed. Also, the structural system model for target zones with different sizes and scales are developed, including hydrodynamic and permeability models for dual porosity reservoirs based on the tectonic stress, imaging log, micro-seismic wave inspection and well test analysis, etc. These models can be used as guides for calculation of the reserves in such a reservoir in Chepaizi oilfield.
