非牛顿流体渗流条件下油层压力的计算方法

Formation pressure computing method under non-newtonian fluids flow

在研究牛顿流松I法的基础上 ,推导出了非牛顿渗流松I法的计算公式 ;给出了非牛顿流体稳定流条件下的压力分布公式及平均压力的计算方法 .并采用泰勒级数和特殊函数相结合的方法对幂律指数趋近 1时的情况进行了简化 ,从而在计算机上实现了当采出井中聚合物溶液浓度很低时的油层压力计算 .

Based on the 'Song I' method under Newtonian fluids flow, the 'Song I' method under non\|newtonian fluids flow has been established. The pressure distribution formula for non\|newtonian fluid under steady flow has been proposed and tile computing method of average pressure has been given. In order to compute by the computer, we gave the reduced express of the conditions that power\|law index is close to 1.
