稠油油田热采开发指标预测方法研究

Prediction of development indexes of heavy oil reservoir steam-injecting production

选取对数正态分布为产量预测模型、Compertz模型为含水预测模型 ,注采关系曲线为油汽比模型 ,联立求解 ,进行开发指标预测 .矿场实例计算结果表明 ,该方法可对稠油油藏注蒸汽开发所有指标和全过程进行预测 。

Logarithm normal distribution model, Compertz model and injection-production curve are selected as production prediction model, water-cut prediction model and oil/gas ratio model respectively. The development indexes can be predicted by simultaneously solving the three models. The result of a case shows that the development indexes and whole development process can be predicted by this method, and this can supply basis for development planning and reservoir engineering design of heavy oil reservoirs.
