稠油油藏储层伤害产能预测新模型及表皮因子研究

基于幂律流体的流变特性方程，推导了幂律流体储层污染前后的垂直井的产能预测模型；推导了适合稠油油藏的表皮因子和非牛顿流体污染井井底压力损失的表达式，并验证了非牛顿流体公式可以还原为牛顿流体公式，分析了非牛顿流体流变特性参数对模型的影响。计算结果对比表明，储层流体的非牛顿特性对模型预测结果具有明显的影响。

Research on new productivity prediction model and skin factor during formation damage in heavy oil reservoir

Productivity prediction model of power - law fluid in the reservoir before and after pollution had been deduced based on rheological behavior equation of the power - law fluid. The formulae were deduced for skin factor avaiable to heavy oil reservoir and the bottom - hole pressure loss of the polluted well with non - Newton fluid. It proved that non - Newtonian fluid formula could be returned to Newtonian fluid formula. The effect of the rheological behavior parameters of the non - Newtonian fluid on the model was analyzed. Comparing the results to the formula,non - Newtonian behavior of the reservoir fluid had obvious influence on the model prediction results.
