塔河油田四区缝洞性油藏缝洞单元划分方法研究

Study on fracture-cavity reservoir fracture-cavity unit division method in Tahe oilfield 4 block

摘要: 随着塔河油田奥陶系油藏的开发,划分缝洞单元的重要性逐渐的表现出来,而缝洞型碳酸盐岩油藏缝洞单元的划分方法没有统一模式,文章通过实例列举出了三种方法,分别是地层压力趋势分析法、井间干扰试井法、示踪剂检测法等。利用这些方法将塔河油田进行单元划分,为指导油藏开发提供了一定的依据。

Abstract: With the development of Tahe oilfield Ordovician reservoir, the division of fracture- cavity unit shows great importance gradually.However there is no uniform model for fracture -cavity unit division of fracture- cavity carbonate reservoir. In this paper,three methods has been listed as examples, which are reservoir pressure trend analysis approach, well interference testing,tracer test respectively.These three methods has been applied in Tahe oilfield for unit division.
