摘要
从东濮凹陷深层低渗油气藏地质特点入手,通过对压裂选井技术的研究,确定了压裂选井方法和不同区块地层压裂时机;并根据储层特征及岩矿组成,研究了压裂液体系及相应储层保护措施,完善了压裂施工工艺技术,提高了压裂有效率,改善了压裂效果。
Starting from the geologic characteristics of deep-zone low permeability reservoirs, right time for selecting wells for fracturing method and fracturing of different blocks are determined by selecting well for fracturing. Based on reservoir characteristics and rock-mineral compositions, fracturing fluid system, and related measures for reservoir protection are studied, fracturing process is improved with good fracturing efficiency, and good postfractruing response.
