摘　　要：为明确陈堡油田泰州组不同水平井的水淹特征,在研究水平井水平段储层物性分布特征的基础上,开展了水平井剩余油及水淹规律的油藏数值模拟研究。根据水平段的物性分布特征,将水平井分为均匀型、两段式和多段式三种类型。数值模拟研究结果表明:均匀型水平井的水淹模式为线状见水整体水淹模式,两段式水平井的水淹模式为点状见水整体水淹模式,多段式水平井的水淹模式为点状见水局部水淹模式。在确定不同类型水平井水淹规律的基础上,进一步提出了相应的治理对策,有效指导了现场实际应用。In order to clarify waterflooding characteristics of horizontal wells in Taizhou Formation(K2 t13) of Chenbao Oilfield,it was carried out study on distribution characteristics of reservoir physical properties in horizontal section.On this basis,combined with reservoir numerical simulation,it was carried out studies on remaining oil distribution and waterout characteristics for three horizontal wells.According to the distribution characteristics of reservoir physical properties in the horizontal section,the horizontal wells were divided into three types:uniform,two-stage and multi-stage.Results of numerical simulation showed that the waterflooding mode for uniform horizontal wells is linear breakthrough waterflooding in the whole horizontal section;the waterflooding mode for two-stage horizontal wells is punctiform breakthrough waterflooding in the whole horizontal section;the waterflooding mode for multi-stage horizontal wells is punctiform breakthrough waterflooding in the local horizontal section.Finally,adjustment measures for different types of horizontal wells were proposed to effectively guide the field application.
