摘要
在分层注水、分层压裂等工艺措施条件下,水驱特征曲线直线规律将会发生改变,给油田开发指标预测带来了困难。针对这种情况,从油藏工程原理出发,采用水驱曲线分解与合成的方法建立了措施调整后开发指标预测模型,并通过优化方法确定了模型参数。经过油田实际开发数据检验,达到了较高的预测精度,可用于油田年度规划、长远规划编制工作中的开发指标预测。
Straight line law of water flooding characteristic curve may change as zonal injection and separate layer fracturing etc.are performed,causing several difficulties for oilfield development index prediction.This paper adopted decomposition and synthetic method for water flooding characteristic curve to construct a model to predict the development indexes after measurement modification based on reservoir engineer principle.Also model parameters are defined with optimization method.Real oil development data proved this model has higher prediction accuracy with the capability of predicting development index for oilfield annual plan and long-term program.
