大位移井钻井技术是伴随着水平井、定向井逐步兴起的一种高科技钻井技术,是水平井、定向井、深井、超深井等技术的综合表现,基本完全涵盖了当前钻井界上最为先进的技术~([1-3])。当前大位移水平井的位垂比是相对接近1:1的水平井,为了最低限度降低和客服井下磨阻扭矩,充分优化井眼轨道钻井工艺设计、施工方案、钻具组合、相关钻井参数、以及对钻井液泥浆性能调控等关键技术,从而实现对井眼轨迹的有效控制。
Large displacement well drilling technology is a kind of high-tech drilling technology that is accompanied by the gradual rise of horizontal and directional wells. It is a comprehensive performance of horizontal wells, directional wells, deep wells and ultra-deep wells. It basically covers the most advanced drilling industry Technology ~ ([1-3]). In the current horizontal wells with large displacement, the horizontal and vertical ratios are relatively close to 1: 1 horizontal wells. In order to minimize the downhole resistance torque and customer requirements, the wellbore trajectory drilling technology design, construction scheme, drilling assembly, drilling parameters, As well as drilling mud performance control and other key technologies, in order to achieve effective control of well trajectory.
