摘要
本文首先用点源函数和格林函数法，推导出拉普拉斯空间线源解。沿井筒平均均一流量解可得无限导流解，在拉普拉斯空间用叠加原理加上井筒储存和表皮效应的影响，再用STE－FEST数值反演方法得到含井储和表皮的真实空间解。然后对水平井单相流压力解进行剖析，研究了具有不同边界组合的侧向无限大油藏中水平井的试井分析方法，通过参数组合，首次研制出考虑井筒储存和表皮因子的更具有实用价值的理论图版。
This paper firstly derives the line-source solutions in Laplace space by point-source function and Green's function. To average the uniform-flux wellbore solution, the infinite-conductivity wellbore solution is obtained. Wellbore-storage and skin effects may be added to the no-storage and no-skin solutions in Laf,lacespace by superposition. The equations are converted into time space with Stehtest's inversion algorithm. Tu analyze the behavior of the pressure response in horizontal well test methods for well test interpretation are inv(3stigated. A new type-curve with wellbore storage and skin effects is presented,and this new type-curve is found to be more efficient.
