| 摘 要： | 对于以水平井井网整体开发的油藏,后期加密的水平生产井产能评价过程应综合考虑其他油水井的干扰影响。基于镜像反映原理与微元线汇理论,给出任意水平井注采井网条件下加密水平井产能正、负因子的定义,建立任意水平井注采井网条件下加密水平井稳态产能评价半解析模型,在考虑井网内部其他油水井干扰以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影响的前提下,定量分析不同油水井工作制度、不同注采井距对加密水平井产能的影响。应用实例表明:新模型的产能计算结果与实际产能相对误差小于15%,是水平井注采井网条件下加密水平井产能评价的一种有效手段;井网内部油井产能随水井注入量的变化呈线性变化,胜利油田某油藏的合理注采井距应控制在1.0～1.5倍水平段长度。 |

| Abstract: | Productivity evaluation for horizontal well in horizontal injection and production pattern should take the interference of other oil or water wells into account.On the basis of the mirror-image method and source-sink theory,the positive factor and negative factor of productivity were defined.A semi-analytical model of productivity evaluation for infill horizontal well in random horizontal injection and production pattern was built,in which the interference of other wells and the pressure drop caused by wall... |
