裂缝性油藏水平井稳态解产能公式研究

本文首先推导出矩形油藏中垂直裂缝稳态解公式，在此公式的基础上，推导出裂缝性油藏水平井稳态解公式，在推导过程中，考虑了油藏顶、底边界、两侧边界，完井方式，油藏基质各向异性以及垂直裂缝部分穿透油层等因素对水平井产能的影响。

A STEADY SOLUTION FORMULA OF HORIZONTAL WELL PRODUCTIVITY IN A FRACTURED RESERVOIR.

This paper firstly derives a steady solution formula of vertical fracture in a rectangular reservoir, on the basis of that, the paper then derives horizontal well's productivity formula at a steady state in a fractured reservoir. In the process of formula derivation, many factors such as boundaries on the top and the bottom of reservoir, boundarise at both sides of reservoir,completion methods (open hole, slotted liner, cemented and perforated liners), anisotropy of reservoir matrix and fracture partial penetration, which have influenced on horizontal well's productivity, are considered. Finally, in the paper the calculation example and a few conclusions are given.
