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STEFEST数值反演方法得到含井储和表皮的真实空间解。然后对斜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斜井的试井压力曲线特征，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。
First, point source function and Green’s function method are used to deduce the Laplace space source solution. Infinite diversion solutions are obtained along the mean flow rate of the wellbore. The superposition principle and the effect of wellbore storage and skin effect are used in Laplace space. The real space solution containing well storage and epidermis is obtained by STEFEST numerical inversion method. Then, the single-phase pressure solution of inclined shaft is analyzed, and the characteristics of well test pressure curve of inclined shaft in lateral infinite reservoirs with different boundary combinations are studied. Through the parameter combination, the wellbore storage and epidermal factor are developed for the first time Theoretical plates with practical value.
