摘　　要：下T6-361井是一口双靶定向井,由于受地面和地质条件的限制,必须穿越9口井,其中最近的4口井防碰距仅为13～32m,钻井施工难度大,是一口较典型的多井防碰绕障定向井。在优化井身剖面设计、优选钻具组合、采用导向钻井技术的基础上,采取了一系列安全钻进措施,顺利钻至设计井深。对该井的地质工程设计、井眼轨迹控制及防碰绕障技术等进行了介绍,对同类型井的施工有一定的借鉴。Xia T6361 is a double targets directional well, which must be drilled through 9 wells for the surface and geological conditions. The distances from it to the nearest 4 wells of them are different from 13 to 32m, therefore, the drilling operations are very difficult. A series of safety measures were taken to drill to target depth successfully: optimizing well trajectory and drill string assembly, employing steering drilling, and other actions. The technology can be referenced to similar well constructions.
