The invention provides a real-time measurement system for underwell vibration. The real-time measurement system comprises a power supplying unit, a centering guide unit, a vibration measurement unit,a taper sealing cap and an orientation tray, wherein the vibration measurement unit has a single-chip microcomputer, a protective housing, a copper joint assembly and a vibration parameter meter; theorientation tray is fixedly connected with a drill collar to fix the real-time measurement system for the underwell vibration; the tapered sealing cap is fixedly connected with the orientation tray toreduce flow speed of drilling fluid; the vibration parameter meter is disposed in the protective housing and electrically connected with the single-chip microcomputer to measure relative data relative to drilling tool vibration and send the measured data to the single-chip microcomputer; the drilling tool vibration data can be processed by the single-chip microcomputer and stored by the same; thecentering guide unit is fixedly connected between the power supplying unit and the protective housing to balance the real-time measurement system for underwell vibration; and the power supplying unitis electrically connected with the single-chip microcomputer and the vibration parameter meter to provide electricity. The real-time measurement system for underwell vibration can measure and store underwell drilling tool vibration data in real-time.
Description
technical field [0001] The application belongs to the field of downhole vibration measurement, in particular to a downhole vibration real-time measurement system. Background technique [0002] With the increasing demand for oil and gas, and the drilling target moving towards deeper and more complex oil and gas reservoirs and unconventional reservoirs, it is increasingly difficult to increase the drilling speed. It is caused by factors such as drill bit wear, insufficient wellbore purification, poor mud performance, etc. Factors such as rock breaking efficiency induced by drilling tool vibration are ignored. During the drilling process, the drill string is the link between the surface equipment and the bottom hole drill bit. The contact and collision between the drill string and the well wall and the heterogeneity of the formation lead to the unsteady load on the drill bit, so that the dynamic load is transmitted to the drill bit in the form of vibration. The drilling tool i...
