摘要
在水驱油藏数值试井模型的基础上,建立了聚合物驱油藏生产历史阶段和不稳定试井阶段的多相流试井解释模型,采用数值试井方法对模型进行求解,结合模拟退火优化算法编写了试井解释软件。该软件在孤东油田七区西 Ng54层注聚区进行了应用,效果良好,模拟出了该区块的渗透率分布。
On the basis of numerical well testing model in a water-driven reservoir, this paper established multiphase well testing models of polymer flooding reservoirs in the producing period and the unsteady well testing period. The solutions for these models were given by numerical well testing technique. A well testing interpretation software combined with the simulated annealing optimized arithmetic has been applied successfully in the 7th region of Gudong Oilfield, and the permeability distribution in the block was simulated.
