摘要
针对多层砾石充填完井的渗流特点 ,将每个产层在径向方向上分成 3个区域 ,即砾石充填区、射孔区、地层径向流区 ,每个区域有各自的渗流方程 ,对n层油藏将有 3n个渗流方程 ,对砾石充填区采用边界元 ,对射孔区采用有限元 ,对地层径向流区采用半解析半数值解 ,最终得到各区域的压力损失及表皮系数 ,以及井底压力及分层产量与时间的变化关系。
As to multi-layer reservoirs,each layer can be divided into three areas:area of gravel-packing,area of perforation,area of radial flow. Each area has its own governing equation. The equations are set up and solved by corresponding numerical methods. Then several parameters,such as pressure and output of each area,are acquired and studied.
