摘要
本文应用单井储层综合评价技术,通过对中部气田奥陶系古风化壳储层特征、成因、孔隙演化及控制因素等的研究,建立了储层概念模式。它是受控于蒸发潮坪相带和古岩溶作用的中低孔隙度、低渗透、不均质层状裂缝-孔洞复合型的膏溶白云岩风化壳储层。对该区储层作了综合评价。
By means of a single well composite reservoir evaluation technique, based on a study of the characteristics and genesis of the weathering, reservoir formation, controlling factors of the evolution of pore geometry, etc., a conceptual model for the Ordovician reservoir in the middle gas field is constructured. This is a medium-low porosity, low permeability, heterogeneous, layed fracture-porous type with gypsum dissolution dolomiter weathering reservoir formation governed by evaporate tidal plain phases belt and paleo-karst. A comprehensive evaluation of this reservoir formation is presented.
