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。
In this paper, point source function and Green’s function method are firstly used to derive Laplace space source solution. Infinite diversion solutions are obtained along the average wellbore flow rate. In the Laplace space, the superposition principle and the effects of wellbore storage and skin effect are used. Then the real space containing wells and epidermis is obtained by STE-FEST numerical inversion solution. Then the single-phase pressure solution of horizontal well is analyzed, and the well test analysis method for horizontal wells in lateral infinite reservoirs with different boundary combinations is studied. Through the combination of parameters, the wellbore storage and the epidermal factor are developed for the first time. Practical value of the theoretical version.
