摘要: 储层孔隙结构及物性特征是影响含水上升率及开发效果的本质因素。依据储层渗透率、孔隙结构、岩石类型等将双河油田的储层划分为4种类型,研究了不同类型储层的含水上升规律,指出了Ⅲ、Ⅳ类储层单元的挖潜途径,现场应用表明,挖潜效果良好。Abstract: Reservoir pore structure and physical properties are the essential elements that have an impace on rising rate of water-cut and development effect. The reservoirs in Shuanghe oilfield are divided into 4 types according to permeabilty pore structure and rock type. This paper studies water-cut increasing pattempresents production potential tapping procedures in the Ⅲ and Ⅳ types of reservoir unit. Field application shows that the production potential tapping effect are remarkable.
