摘要: 塔河缝洞型油藏开发动态分析形成“动态三定法”技术序列,即:酸压曲线定井储关系,注水指示曲线定体积变化,能量指示曲线定泄油半径变化。与储集体地球物理识别缝洞中心点的“静态三定法”刻画技术深入融合、相互印证,可指导现场应用实践,合理选择改造措施,实现油井控制储量最大化。Abstract: For fractured-and-vuggy carbonate reservoirs in the Tahe oilfield, we proposed a dynamic analysis method composed of three types of curves. We used acid fracturing curves to study reservoir relationship, water flooding curves to study volumetric changes, and energy curves to study drainage radius changes. Combined with the previous static methods to identify cave center, the dynamic method successfully guided field practice and reservoir reformation, hence maximized well control reserves.
