注蒸汽开发稠油油藏可采储量预测方法探讨

Discussion on forecasting method of recoverable reserves in heavy oil reservoirs produced by steam injection

通过对稠油开采机理和油藏类型的分析 ,提出了注采关系曲线法和水驱曲线法为注蒸汽开发稠油油藏预测可采储量的主要方法 ,并对这两种方法的适用性进行了分析。运用数值模拟的方法 ,对稠油油藏在油藏条件下经济流动极限进行了研究 ,建立了产能与流度的关系曲线。

Based on the analysis of development mechanisms and reservoir type of heavy oil, it is proposed that injectionproduction curve method and the water drive curve method are the main methods of predicting recoverable reserves in heavy oil reservoirs developed by steam injection. The available conditions of two methods are studied. Using numerical simulation, an economical flow limit is investigated in heavy oil reservoirs, a productivitymobility relationship curve is built.
