OPTIMIZING DESIGN OF SWABBING PARAMETERS FOR POLYMER FLOODING AND ITS APPLICATION

室内实验表明， 聚合物溶液的流变性符合幂律模式； 考虑到采出液的非牛顿特性， 提出了聚合物驱抽油井抽汲参数优化设计方法。该方法利用模糊数学综合决策理论对各个参数进行综合评价， 全面地反映出了各种因素对抽汲参数优化设计的影响程度， 从而给出抽汲参数的最佳设计方案。现场应用表明， 该方法理论正确，

The laboratory tests suggest that the rheological property of polymer solution is coincident with power low rule; Taking the non-Newtonian behavior of the produced fluids into account we put forward the optimizing design method of swabbing parameters for polymer flooding. When using this method every parameter is comprehensively evaluated according to the integrated decision theory of fuzzy mathematics. It comprehensively reflects the effect of each factor on the optimizing design of swabbing parameters, and then provides the optimizing designing project for swabbing parameters. The field tests prove that based on correct theories this method can be popularized in the near future.
