Abstract

The invention relates to the technical field of logging while drilling in oil drilling, in particular to a working parameter measurement device for oil drilling positive displacement motors. The working parameter measurement device mainly comprises a permanent magnet, a hall switch sensor, a micro-machined gyroscope, a temperature sensor, a signal conditioning circuit, a single chip microcomputer circuit and a high-pressure sealing cover plate, and is arranged on a screw to form an integral structure. The permanent magnet is mounted on a screw rotor or anti-falling non-magnetic-conducting portion; and the hall switch sensor, the micro-machined gyroscope, the signal conditioning circuit and the single chip microcomputer circuit are mounted in strip grooves machined on the screw shell. Screw rotation speed, drill collar rotation speed, working temperature and running time are measured by the device; and the working parameter measurement device is simple in structure, easy to replace and suitable for bath and series production.

Description

technical field [0001] The invention relates to the technical field of logging-while-drilling for petroleum drilling, in particular to a device for measuring the rotational speed, temperature and time of a screw drilling tool while drilling in petroleum drilling engineering. Background technique [0002] During the drilling process, it is very important to know the working status of the drilling tool in time for safe and efficient drilling. This requires accurate detection of various drilling engineering parameters near the drill bit, including running time, temperature, and the rotational speed of the drilling tool. Wait. With the increase of drilling depth, especially the development of various branch wells, horizontal wells, and fishbone wells, it will have a great impact on the safety and efficiency of drilling production. Drilling accidents happen from time to time, real-time measurement of changes in drilling engineering parameters such as the rotation speed of the sc...
