摘　　要：针对渤海某油田平台无多余井槽(仅剩一个井槽),但需要实施两口井,一口为滚动勘探断块区域,一口为生产调整井的目的。根据勘探和开发的次第设计需要,从定向井轨迹和井身结构实施的可行性两方面,采用主井眼三段式轨迹设计,一方面规避丛式井表层防碰风险,另一方面规避下部断层地质风险,兼顾侧钻分支井眼轨迹的可行性,侧钻点的选择以进尺最小化、轨迹难度最低化出发做了三个方案的横向对比,最终以轨迹和工程的可操作性出发合理设计井身结构。实现一个井槽,先勘探后侧钻分支开发,利用定向射孔沟通两个井眼,采用合采技术实现高产量生产。There is only one well slot remaining in Bohai X producing platform. In order to implement two wells, used multiple bottom technology, one bottom for exploration and another for present a new development well. Firstly, the feasibility of borehole trajectory is demonstrated. The main hole trajectory design considered three segments, avoid the cluster wells surface anti-collision risk, avoid a lower risk of geological faults and account of branch borehole. Finally, the optimal trajectory design and well structure design are obtained.Through the implementation of branch well technology, the higher yield of the well is finally obtained.
