摘　　要：在凝析气藏、油藏聚合物驱、注水等开发过程中,往往伴随着地层流动系数场的变化,而压力测试资料是一种比较准确的预测地层流动系数场分布状况的方法,是目前国内外的研究热点和难点问题。为此,通过对Yeh-Agarwal确定地层流动系数场分布方法进行修正,提出了用试井解释资料来确定地层流动系数的方法,并利用matlab等计算机语言,编制了流动系数场预测软件,对某断块五井组的地层流动系数场进行预测,预测结果与实际较吻合,此研究对聚合物驱、注水油藏、凝析气藏等具有一定的指导意义。In the development process of condensate gas reservoir,polymer flooding and water injection,formation flow coefficient field is often variable. The formation flow coefficient is an important index to guide the reservoir development. Commonly,the pressure test data is used to analyze the change laws of formation flow coefficient,and it is a more accurate method of predicting the flow coefficient field stratigraphic distribution. So,based on the predication model of flow coefficient distribution,and combining with multipoint geologic parameter statistical theory,the forecast model of reservoir flow coefficient field was established. The method of the determining flow coefficient field distribution was corrected by Yeh-Agarwal method. And the flow coefficient field prediction software was programmed by using matlab computer language. The insitu prediction result of flow coefficient field in the five well groups of x fault block agreed well with the actual result. This research has a certain guiding significance for the development of polymer flooding reservoir,water flooding reservoir and condensate gas reservoir.
