摘　　要：介绍一种石油钻井中钻具扭矩〔包括悬重和钻压〕的随钻遥测方法，该方法是在方钻杆的上、下两端各增加一个短接，分别放置扭矩、悬重传感器及信号处理电路，通过调频发射和接收，显示方钻杆的扭矩及钻具的悬重和钻压。本方法的特点是能实测施加于方钻杆上的真正扭矩。A method of remote measurement of torque on drilling string (including suspending and drilling weight) while drilling is introduced in this paper. Two 'joints' are added to the top and bottom ends of the kelly respectively. The torque and suspending weight transducers and signal processing circuits are installed in the joints. The signals of torque and drilling weight, therefore, may be transmitted and received through modulation frequencies. The advantage of this method is that the actual torque acting on the kelly can be measured while drilling.
