摘　　要：在注水开发过程中 ,储层非均质性是影响剩余油分布的一个重要的地质因素 ,它制约着油田高产稳产期的长短和最终采收率的高低。探讨了将地质统计学中的变异函数引入到平面非均质性研究中的可行性 ,并将其应用到中原油田胡十二断块平面非均质性研究中。研究结果表明 ,变异函数表征储层的非均质性具有很好的可信性和可行性。In waterflood development,heterogeneous reservoir is a key geological factor which controls the lifetime of high yield and stable production periods. In this paper,the possibility of introducing variance function into plane heterogeneous study has been discussed and an example of using the method has been given. The result of the 12th Block of Huzhuang Oilfield,Zhongyuan Oilfield has also demonstrated the credibility and feasibility of using variance function in plane heterogeneous study.
