摘要:

牛顿区半径越小，非牛顿区压力和压力导数曲线位置越高。该模型对聚合物驱试井资料解释和聚驱效果评价具有重要作用。

Abstract:
 

In order to analyze the pressure behaviors of polymer flooding reservoir, a mathematical

well testing interpretation model of NewtonnonNewtonian composite fracturing vertical well was established based on polymer flooding process.

According to the basic theory of point source function, the Laplace space analytic solution of finiteconductivity fracturing wells was obtained

by using Laplace integral transformation and finite cosine Fourier transform; on this basis, the analytic solution of the mathematical well

testing interpretation model of the finiteconductivity fracturing vertical wells in NewtonnonNewtonian composite reservoir was derived by

combining the fracture conductivity function. Finally, the typical dimensionless bottomhole pressure and pressure derivative characteristic curves

were calculated and plotted by Stehfest numerical inversion. The results show that the power law exponent has a certain influence on the change of

the bottomhole pressure. The smaller the power law exponent, the more obvious the upper warp of the nonNewtonian pressure and pressure

derivative curves, and the curves are straight lines with a slope of (1n)/(3n). The greater the conductivity, the less obvious the

characteristics in the bilinear flow stage. The higher the mobility ratio in the NewtonNonNewtonian zone and the smaller the radius of Newton

zone, the higher the position on the nonNewtonian pressure and pressure derivative curves. The model plays an important role in the

interpretation of polymer flooding testing data and the effect evaluation of polymer flooding.
