射孔水平井的产量预测及影响因素分析

国内外大量研究表明水平井筒内的压降对水平井内的生产动态有较大影响，本文将给出考虑水平井压降时射孔水平井产量的耦合方程并用Visual Basic软件编制计算产量的可视化窗口；通过实例计算对影响产量的敏感性因素进行分析，并对无限导流情况下的水平井的产量和考虑水平井压降时水平井的产量进行对比。

Perforated horizontal well production forecasts and analysis of influencing factors

A large number of domestic and foreign studies have shown that the horizontal wellbore pressure drop have a large effect on the production performance of horizontal wells. By considering the pressure drop of the horizontal wells, we deduce the coupled equations of the horizontal well production. Visual window developed by using Visual Basic software that can calculate the production of perforated horizontal wells conveniently. Though an example calculation to know how the sensitivity factors affect the production of horizontal wells and compare horizontal wells production between the infinite conductivity case and consider horizontal wellbore pressure drop case.
