水驱特征曲线与产量预测模型的联合应用

A Joint Application of Displacement Curve and Production Prediction Model

介绍了甲型和丙型水驱特征曲线及产量预测模型的基本关系式；并将水驱特征曲线与产量预测模型进行联立求解，建立了含水率与开发时间之间的函数关系式，同时给出了不同开发年限的含水率、年产油量与累积采油量等各项指标的计算方法。经萨玛特洛尔油田的实例计算应用，认为该方法用于油田开发动态预测，既解决了水驱特征曲线预测中缺少时间因素的问题，又解决了产量预测模型中缺少含水率的问题。

： The basic correlation of Models for Type A and Type C displacement curve and production prediction are presented， and the solutions for these models have been found simultaneously， followed by developing a functional correlation of water cut vs． production historyt． Meanwhile， the methods for calculating water cut， annual oil production rate and accumulative production， etc． are provided． By applying them into Samaterol oilfield， it is indicated that the methods can be well used in performance prediction of an oilfield development， because such problems without time factor in curve prediction model and without water cut in production prediction model have been all solved．
