摘要
依据幂律流体型稠油的渗流方程,推导出了一种考虑启动压力梯度及幂律特征的稠油油藏双曲递减模型。以渤海S油田为例,对新的稠油油藏双曲递减模型进行了验证和分析,结果表明,本文方法适用于稠油油田开发初期开发指标的预测,其结果更接近油田实际生产数据。
Based on the seepage equation of heavy oil as a type of power-law fluid, a new hyperbolic decline model of production was derived for heavy oil reservoirs, in which the threshold pressure gra- dient and power law features were considered. This new model was validated and analyzed by u- sing the actual data in S oilfield, Bohai bay, and the results have shown that this approach is suit- able for predicting the early development index of
