摘要
对一种较新的水平井布井的方式——多井底水平井的渗流问题.运用拟三维方法进行分析.得出了在平面上和剖面上的解析解.再运用等值渗流阻力法得出了含三维空间的解和二维空间中的流场变化.提出了产能计算公式.其综合公式能更完善地反映渗流的基本规律.所提出的方法对于水平井油藏工程研究提供了基本分析手段.
Some problems of multiwellbore horizontal well flow is solved by using the pseudo-3D analytical method. The calculation formulas in plane and in vertical cross section are derived. By use of the principle of equivalent flow resistance the solution of a 3D problem was obtained. The isopotential and flow line figure is given. A new method for calculating horizontal well productivity is established. It can decribe the fundamental flow law. It can be also successfully used as an effective tool for analysis of reservoir engineering for flow of multiwellbore horizontal wells.
