塔里木油田缝洞型碳酸盐岩油藏开发对策研究

缝洞型油藏储层类型多样，非均质性严重，油气水关系复杂，给这类油藏的开发带来了很大困难。应用数值模拟方法对缝洞型油藏的开发规律进行了研究，分析了不同类型油藏井型、水体能量、开采速度、开发方式对开发效果的影响，结果表明：无底水存在的单缝洞模式适合采用直井开发，而有水体的单缝洞情形更适合用水平井进行开发。结合塔里木盆地碳酸盐岩油藏注水的成功实例确立了注水吞吐等主要的开发技术对策，为此类油气藏的开发提供了理论依据。

RESEARCH ON THE DEVELOPING STRATEGIES OF THE FRACTURE-CAVERN CARBONATITE OIL RESERVOIR IN TARIM OILFIELD

It is difficult to develop vuggy fractured reservoir because it is characterized by reservoir diversification，strong heterogeneity and complex oil-water relationship.In this paper，the developing rules of vuggy fractured oil reservoir is studied based on the numerical simulation method，and the developing effect of the factors such as well type，aquifer，recovery rate and development is analyzed.The results indicate that vertical well is suitable for single fracture-vug mode without aquifer，while horizontal well fits for aquifer pattern.Combined with the successful injection example of Tarim carbonatite reservoir，the dominant developing strategy such as injection by production well is determined，which provides theoritical support for developing similar reservoirs.
