摘 要：碳酸盐岩缝洞型油藏由于裂缝、溶洞的分布随机性强，其流动机理和开发方式与常规的碳酸盐岩裂缝性油藏存在很大差别，注水开发目前处于试注阶段，还没有形成相应的油藏注水开发理论体系。因此，建立适合碳酸盐岩缝洞型油藏的注采关系及注水方式，优化碳酸盐岩缝洞型油藏不同注水方式下的注采参数，是碳酸盐岩缝洞型油藏注水开发理论与方法的关键基本问题。本研究以油藏工程学、流体动力学理论为基础，以室内物理模拟实验、数值模拟、矿场注水试验和大量动态资料统计分析为基本手段，充分考虑理论研究、室内实验研究与现场试验研究相结合，针对课题研究目标，选择具有代表性的缝洞单元模型进行重点研究，对油藏能量、注采关系、注水方式、注采参数、注水开发动态及开发效果评价方法进行深入研究，进而形成系统的缝洞型油藏注水开发技术政策及注水开发效果评价方法。2013年通过进一步开展室内物模和数值模拟研究，建立了缝洞型油藏室内三维注才井组实验模型，完善了缝洞型油藏单元注水方式，优化了缝洞型油藏单元注水的注采参数，进一步完善了不同类型岩溶缝洞储集提注水技术政策。该课题完成了年度研究计划内容和目标。

Abstract：Because of cracks， caves strong distribution randomness in Carbonate fracture cave reservoir. Its current mechanism and development mode have big difference with the conventional fractured carbonate reservoirs. Water injection development is currently in trial stage， Not form the corresponding theoretical system waterflooding reservoir.Subject to reservoir engineering、fluid dynamics theory， In physical simulation experiments， numerical simulation， the mine water testing and statistical analysis of a large number of dynamic data as the basic means. Fully consider the theoretical research， experimental research experiments and field studies combining indoor， For research objectives， Select fractured unit model to focus on a representative study， On the reservoir of energy， the relationship between injection， water injection mode， injection parameters， water development and development effectiveness evaluation method of dynamic depth study. Build relationships and water injection methods suitable for fracture-cave carbonate reservoir， Thus forming system vuggy reservoir waterflood injection technology policy and development effectiveness evaluation. Further indoor physical model and numerical simulation in 2013 year， Established a three-dimensional vuggy indoor injection wells experimental model group， Improved vuggy reservoir unit injection mode， Optimize the injection parameters vuggy reservoir water injection unit， Further improve the different types of karst fractured reservoir provides water technology policy. The subject completed the annual research program content and objectives.
