摘要
预测边底水油藏见水时间、确定无水期采收率 ,对于改善注水开发的边底水油藏的开发效果、实现控水稳油、提高水驱采收率有着重要的意义。以物质平衡方式和不定态水侵公式等油藏工程理论为基础 ,得出无水期采收率和油藏见水时间的计算公式。在对有关参数进行详细讨论的基础上 ,以辽河油田某油藏为实例 ,将计算所得结果与实测结果相比较 ,相对误差很小 ,说明了本方法的精度较高。由于方法来源于油藏工程理论 。
Predict the water coming time and the no water recovery has the important sense for improving the development effect.This article is based on the material balance equation and the no fixed water inroad equation,educe the equation of the no water recovery and the water coming time.Through the discussion of the relevant parameters,and get the result from the example,and compared it with the measure result,comparatively error is very little,it proves the precision and the currency of the method.
