摘要
从渗流流态讲侧钻井是水平井渗流的一种近似,不能沿用裸眼井复合油藏试井模型。文章从侧钻井完井方法人手建立了侧钻井不稳定渗流数学模型,采用边界元法解出了侧钻井不稳定渗流数学模型的分析解,为评价侧钻井对储层的伤害提供了理论依据。
In view of seepage fluid,side well drilling was similar to plane well seepage,in which open well comprehensive reservoir testing model could not be adopted.The completing method of lateral drilling was discussed in this article to set up the mathematical modeling of unstable seepage for lateral drilling.Boundary element method was used to work out the analytical solution to the mathematical modeling of unstable seepage for lateral drilling, thus the theoretical gist for evaluating the harm done by lateral drilling on reservoir formation was provided.
