水平井开发基础理论─—物理模型研究

PHYSICAL MODELING OF HORIZONTAL WELLS

在概述水平井开发技术的基础上，用电解模型，根据水电相似原理，对水平井开发过程中井筒附近压力分布，油藏中压力场的形态，影响水平井单井开发效果的因素，水平井和直井联合布井情况下的开发效果等几个基本理论问题进行了探讨，并用本模型的实验结果对目前水平井产量计算的经验公式做了验证，最后提出了系统研究水平井开发理论的思路和构想。

This paper presents a hydrau-electrical analog experiments on the basis of the similarity in Ohm′s and Darcy′s laws. By using the results of the experiments,it is analyzed and inves-tigated the pressure distribution around wellbore, pressure contours,factors of affecting theproductivity of horizontal wells,associated development of horizontal wells and vertical wellsand productivity formula developed by other authors.It is concluded that horizontal wellscan play an important role as alternate tools to vertical wells.
