一种新的稠油油藏蒸汽吞吐OSR预测方法

A New Method for Predicting OSR of Huff and Puff in Heavy Oil Reservoirs

利用HCZ(胡-陈-张)预测模型,可以对已开发油田的年产量和累积产量进行全程预测,并且在实际应用中取得了较好的预测结果。本文将HCZ预测模型应用于蒸汽吞吐稠油油藏,推导出的稠油蒸汽吞吐油汽比程式,可以对蒸汽吞吐稠油油田油汽比进行预测,为油田编制开发方案和中长期规划及储量资产优化提供依据。文中结合油田实例,对蒸汽吞吐稠油油藏的开发进行了预测,取得了较好的预测结果。

The HCZ(HU-CHEN-ZHANG)forecast model is for whole course prediction of annual output and cumulative oil recovery in developing oilfields.This model was applied to a huff and puff heavy oil reservoir.The predicted OSR(oil-steam ratio)was used as basis of oilfield development planning and medium-term and long-term programming and optimization of reserves assets.
