本文提出了层状油气藏中确定多底井压力瞬变特性的分析方法,计算方法是基于拉普拉斯变换及数值反演来产生典型曲线用以直接分析压力瞬变数据,任意方向随意倾斜的任何分支段数大体上都能处理。虽然计算成本将随分支段数的增加而大量增加。但是,大量分支段的情况在实际中是不存在的。
This paper presents an analytical method to determine pressure transient characteristics in multi-well wells in stratiform reservoirs. The calculation method is based on Laplace transforms and numerical inversion to generate typical curves for direct analysis of pressure transient data and arbitrary inclination in any direction The number of any branch can generally be handled. Although the calculation costs will increase with the number of branch segments increased significantly. However, the situation of a large number of branch segments does not exist in practice.
