水驱特征曲线法在东河塘CⅢ油藏注水开发效果评价中的应用

APPLICATIONS OF WATER DRIVE CHARACTERISTIC CURVE IN EFFECTIVENESS EVALUATION OF WATER-FLOOD DEVELOPMENT IN CARBONIFEROUS OIL RESERVOIR ON DONG HE TANG OIL FIELD

水驱特征曲线法是注水开发油田开发效果评价中最主要的方法之一,国内外研究者对其进行了大量的研究,得出了很多经验性的结论。但是,在将这些结论应用到新疆东河塘石炭系油藏时出现了不适应的情况。因此,笔者在总结前人经验的同时,遴选出几个开发效果评价指标,结合油藏地质情况和生产数据,在历史拟合的基础上对一些结论进行了相应的调整,在东河塘CⅢ油藏注水开发效果评价中得到了很好的应用,对油田开发生产起到了很好的指导作用。

Water drive characteristic curve is one of the most important methods in effectiveness evaluation of water-flood oil field.Domestic and foreign researchers have done a lot of research on it and gotten many empirical conclusion.However,when these conclusions were applied in the oil reservoir of carboniferous of Dong He Tang,there was inappropriate situation there.Therefore,after summarizing previous experience,some development indicators having been selected,with the actual geological situation and production data of the oil reservoir,we adjust some of the conclusions on the basis of history matching,and apply them well in effectiveness evaluation of water-flood development in carboniferous oil reservoir on Dong He Tang oil field,which provides guidance to the oilfield development.
