【摘要】 随着油田开发目标的转移,地下油水分布越来越复杂,储层参数发生变化,非均质性进一步加强,以往的水淹层解释方法的不适应性越来越突出,解释符合率低于70%,远远不能满足油田开发要求.利用多元统计分析中的逐步判别法,建立了水淹层的判别方程,使水淹层判别的符合率达到了82%,为进一步提高解释精度具有重要的意义.更多还原

【Abstract】 With the transfer of oil field development project,underground oil and water distribution is becoming more and more complex. The inadaptability of former water flooded layer interpretation method is more and more outstanding with the changes of reservoir parameters and strengthening heterogeneity,so which makes interpret compliance rate less than 70%and can not meet the requirements of oil field development. In this paper the stepwise discriminant analysis of the multivariate statistical analysis is used,and the discriminant equation of water flooded layer is established,that the coincidence rate of the water flooded layer is 82%,in order to further improve the accuracy of interpretation is of great significance.更多还原
