摘　　要：为解决现阶段渤海P油田边部稠油区联合井网开发存在井间干扰认识不清、部署时机不明等问题,利用数值模拟方法对水平井与定向井平面相对位置部署、水平井部署时机等问题进行了研究。研究表明:联合井网井间干扰程度为定向井部署在水平井跟端时干扰最大;定向井部署在水平井中端时区块采出程度最大;对于定向井已开发油藏,含水率越低,部署水平井形成联合井网的累产油提升幅度越大。该项研究对其他类似油田开发阶段联合井网优化部署、提升油田开发效果具有借鉴意义。In order to solve the problems such as unclear understanding of inter well interference and unclear deployment timing in the combined well pattern development in the heavy oil area at the edge of Bohai Oilfield P at this stage,the plane relative position of horizontal well and directional well,and the timing of horizontal well deployment are studied by using numerical simulation method.The study shows that the inter well interference of the combined well pattern is the largest when the directional well is deployed at the end of the horizontal well;When the directional well is deployed in the middle of the horizontal well,the recovery degree of the block is the largest;For developed reservoirs of directional wells,the lower the water cut is,the greater the cumulative oil production will be increased by deploying horizontal wells to form a combined well pattern.This research method can be used as a reference for other similar oilfield development stages to optimize the deployment of combined well pattern and improve the oilfield development effect.
