摘要/Abstract

摘要： 对于以直井、水平井混合井网开采的油藏,后期加密的水平生产井产能计算应综合考虑其他油水井的干扰.基于镜像反映原理与微元线汇理论,建立任意混合井网条件下加密水平井稳态产能计算半解析模型,考虑混合井网内部其他油水井干扰及井筒内由于井壁摩擦与流体加速度造成的压力降对加密水平井产能的影响,适用于任意混合井网条件下(井型任意性、井数目任意性、井位任意性)加密水平井产能计算.

关键词: 混合井网, 加密水平井, 产能计算

Abstract: In productivity evaluation of infill horizontal well interference of oil or water wells are taken into account in a vertical and horizontal well mixed well pattern.With mirror-image method and source-sink theory,a semi-analytical model of productivity evaluation for infill horizontal well in random mixed pattern was built,in which interference of wells and pressure drop caused by wal friction and fluid acceleration were taken into account.It is suitable for infill horizontal well productivity calculation in arbitrary well pattern.

Key words: mixed well pattern, infill horizontal well, productivity calculation
