Intelligent torque meter for drill pipe power tongs

Abstract

The invention discloses an intelligent torque meter for drill pipe power tongs. The drill pipe power tong intelligent torque meter includes a torque value display unit, a torque value monitoring unit and a torque unloading unit, and the torque value display unit includes a digital display instrument, a first pressure sensor, a second pressure sensor and a first data transmitter, The first pressure sensor, the second pressure sensor and the first data transmitter are respectively connected with the digital display instrument; the torque value monitoring unit includes a background computer and a second data transmitter, the second data transmitter is connected with the background computer, and the first The data transmitter and the second data transmitter mutually transmit and receive data information; the torque unloading unit includes an electromagnetic overflow valve, and the electromagnetic overflow valve of the digital display instrument issues an unloading command to control the electromagnetic overflow valve unloading. The invention can realize the control of the torque of the drilling tool, prevent the screw thread of the drilling tool from being damaged due to excessive torque value, and realize automatic torque monitoring.

Description

technical field [0001] The invention relates to equipment used in oil drilling operations, in particular to a drill pipe torque meter. Background technique [0002] In oil drilling operations, it is a very important work link to set, control, monitor and record the make-up torque value of various drilling tools in the process of making-up and breaking-out of drilling tools. If the torque value is too small, it will cause problems such as insufficient connection strength. [0003] At present, manual control of torque value, manual monitoring, recording and regulation of torque have high requirements for operators, and they must have certain experience and proficiency to be competent. The degree of automation is low and the failure rate is high; to extend the service life of drilling tools, It is an urgent problem to prevent safety accidents caused by the damage of drilling tool threads and to improve the automation of torque control. Contents of the invention [0004] In ...

Problems solved by technology

[0002] In oil drilling operations, it is a very important work link to set, control, monitor and record the make-up torque value of various drilling tools in the process of making-up and breaking-out of drilling tools. If the screw thread is too large, it may crack or cause excessive stress; if the torque value is too small, it will cause problems such as insufficient connection strength.

[0003] At present, manual control of torque value, manual monitoring, recording and regulation of torque have high requirements for operators, and they must have certain experience and proficiency to be competent. The degree of automation is low and the failure rate is high; to extend the service life of drilling tools, To prevent safety accidents due to damage to the threaded thread of the drilling tool and to improve the automation of torque control is an urgent problem to be solved
