The priorities are the diversification characteristics of each targetin the subsequent water flooding. According to diversification characteristics of these targets,the paper studies how the heterogeneousness, water flooded condition, interconnectingcondition of zone;key measures injector parameters affect these targets from polymer floodingmechanism. Based on influence equations, production target prediction models are built usingHall curve theory, relative permeability curve, relations of water saturation and relativepermeability and material balance equation. Parameters of models are calculated by the way ofcomputer program and so that a simple, fast way have been gained to predict production targetof polymer subsequent flooding.

与传统的测井资料解释和信息处理技术相比较，在对非均质性较强、物性参数级差较大的储集层物性预测中，人工神经网络技术具有极强的自适应和自学习能力，其通过很强的非线性映射，能够精确地建立储集层参数与测井响应之间的非线性模型。

According to the presumption of rational economic person, policy lagging reasons include: the self-interested body of policy as well as its cost-income calculation; being unequal and nonidentical in need of policy; resort to certain channels that providing policy; decision-makers' finitary rationality.

从理性经济人假定出发，政策滞后的原因包括政策主体的自利性及其成本—收益计算；政策需求的非均质、非同一性；政策供给的路径依赖与决策者的有限理性。

Furthermore, the regular triangle lattice is projected on the random aggregate model, and the different material property of elements is identified and assigned automatically. Then the numerical model is obtained.
