摘要
任丘雾迷山组潜山油藏为大型底水块状碳酸盐岩油藏，目前综合含水已达96．1％，处于高含水低速开发阶段。以任丘碳酸盐岩潜山油藏为例，利用层切片技术和变速成图技术进行构造精细描述，利用调频调谐振幅和多尺度谱分解检测技术进行储层缝、洞分布预测，利用蚂蚁追踪技术和离散裂缝网络建模技术进行双重介质三维地质建模，利用剩余油动态监测技术、AVO储层含油气检测技术、裂缝发育低值区预测技术以及数值模拟技术进行剩余油分布规律研究，形成了一套独具特色的潜山开发后期精细油藏描述方法与技术。采用“高封堵、低酸化、中提液、稀打井”的挖潜方式，取得了较好的挖潜效果，可为同类油藏的地质研究与剩余油挖潜提供借鉴和指导。
The buried hill reservoir in Wumishan Formation in Renqiu belongs to the large-block carbonate reser- voir with bottom water. The comprehensive water cut is as high as 96. 1%, and the reservoir is at the stage of high water cut and low recovery rate. Taking the buried hill reservoir in Wumishan Formation in Renqiu as an example, horizon slice technology and variable velocity imaging technology are used to realize the fine structure description, frequencymodulation tuning-amplitude and multiple scale spectral decomposition testing technology are used to predict the distribution of fractures and caves in reservoir, ant-tracking technology and discrete fracture network modeling technology are applied to conduct the dual-medium 3D-geological modeling, and the remained oil distribution is studied with monitoring technology for remained oil performance, AVO detection technology for hydrocarbon reservoirs, predicting technology for low fracture development area and numerical simulation technology. A set of fine description method and technology, which has its own distinguishing characteristic, for buried hill oil reservoirs at late development stage is formed. The better effect of tapping the oil potential is achieved by ＂ high plugging, low acidification, middle liquid extraction, less drilling＂ method, being able to provide a reference and guide for the geological research and tapping the remained oil potential of the same type of reservoirs.
