摘要

以前许多关于水平井的研究,都没有涉及到井筒压降,通过建立数学模型,提出了简单的解析式,来确定井筒压降对水平井流入的相对影响.用两个无量纲数的简单作用来说明水平井筒中的压降的相对重要性,一个是井筒中流动的雷诺数,另一个是被称为水平井数的新无量纲数.用这一相对关系,优化设计井筒的直径和长度来保证井筒压降不影响产能.
        Wellbore pressure drop are not considered before much of the research on horizontal well.Through the establishment of mathematical model,this paper puts forward a simple analytic expression to determine the relative influence of wellbore pressure drop on horizontal well inflow.Two simple function of dimensionless number is used to illustrate the relative importance of horizontal wellbore pressure drop.One is Reynolds number in the wellbore flow,another is a new dimensionless number referred to as the number of horizontal well.With the relative relationship,we optimize the design of wellbore diameter and length to ensure wellbore pressure drop does not affect well production.
