摘要
在勘探、开发油井试油过程中,当一口井上两个相邻的试油层段之间距离较短时,可能会在套管外产生层间窜通.当两个相邻试油层之间的试油结果比较接近时,往往难以判断,两层是否发生窜通.通过进行单井垂向层间干扰试井并对试井资料进行分析,可以得到井的垂向层间连通情况,为准确地评价单层试油结果提供可靠的依据.以FN4井的垂向干扰试井为例,来具体分析这一试井方法的应用.
During well testing of exploration and development,when distance between two adjacent intervals is short,some problems such as inter-zone communication outside casing voidage may appear.When this two adjacent intervals results of testing are compared only to find that the results are very close,it is difficult to determine whether there is inter-zone communication or not.In order to solve this problem,a vertical interference test method was applied to analyze well test data of single-interval to determine two vertical intervals are connected or not,which can provide a reliable basis for accurately assessing the results of well testing.FN4-well testing data were utilized as an example to analyze the application of this testing method.
