    • A drilling system includes a work string supporting a bottom hole assembly. The work string including lengths of pipe having a non-metallic portion. The work string preferably includes a composite umbilical having a fluid impermeable liner, multiple load carrying layers, and a wear layer. Multiple electrical conductors and data transmission conductors are embedded in the load carrying layers for carrying current or transmitting data between the bottom hole assembly and the surface. The bottom hole assembly includes a bit, a gamma ray and inclinometer instrument package, a propulsion system with resistivity antenna and steerable assembly, an electronics section, a transmission, and a power section for rotating the bit. The electrical conductors in the composite umbilical provide power to the electronics section and may provide power to the power section. The data transmission conduits in the composite umbilical transmit the data from the downhole sensors to the surface where the data is processed. The propulsion system includes two or more traction modules connected by rams disposed in cylinders for walking the bottom hole assembly up and down the borehole. The propulsion system includes a steerable assembly, controlled from the surface, for changing the trajectory of the borehole.
    • 钻井系统包括支撑井底组件的工作柱。 工作串包括具有非金属部分的管的长度。 工作线优选地包括具有不透液体的衬垫,多个承载层和耐磨层的复合脐带。 多个电导体和数据传输导体嵌入承载层中,用于在底孔组件和表面之间承载电流或传输数据。 底孔组件包括钻头,伽马射线和倾斜仪仪表包,具有电阻率天线和可转向组件的推进系统,电子部件,变速器和用于旋转钻头的动力部件。 复合脐带中的电导体为电子部件提供电力,并可向电源部分提供电力。 复合脐带中的数据传输管道将数据从井下传感器传送到处理数据的表面。 推进系统包括由设置在气缸中的柱塞连接的两个或更多个牵引模块,用于在钻孔中上下移动底部孔组件。 推进系统包括从表面控制的用于改变钻孔轨迹的可操纵组件。
