摘要:
采用油藏工程法建立数学模型,从理论角度对注水利用率进行评价和预测,结果与实际相比误差较大。为此,文中从油田实际出发,利用无因次注入 ̄采出曲线推导、预测不同采出程度下水驱油田的存水率与水驱指数变化规律,利用水驱规律曲线推导、预测不同含水率阶段的存水率与水驱指数变化规律。以PX ̄7断块油田为例进行计算,存水率和水驱指数预测结果与实际相比误差均小于3%。该预测方法所需数据易获取,简单实用,预测结果为PX ̄7水驱断块油田开发评价及调整提供了指导。
Abstract:
The results of the evaluation and prediction of the water injection utilization rate calculated by the reservoir engineering method from the theoretical point of view are larger than the actual results. In this article, starting from the actual injection and production rules of oilfields, the dimensionless injection-production curve is used to predict the variation of water storage rate and water flooding index of water flooding oilfields under different mining degrees, and the water flooding law curve is used to predict the change of water storage rate and water flooding index in different water-bearing stages. Taking the PX-7 fault block oilfield as an example, the error between the water storage rate and the water flooding index prediction result is less than 3% compared with the actual value. The required data is easy to be obtained, and the prediction method is simple and practical. The prediction result provides guidance for development evaluation and adjustment of PX-7 fault block oilfields.
