Combined damping system and device for inclination measuring cartridge of wireless drilling inclinometer

Abstract

The invention discloses a combined damping system and device for an inclination measuring cartridge of a wireless drilling inclinometer. In the combined damping device, in an axial direction of an inclination measuring cartridge body, one end of the inclination measuring cartridge body is connected with a damping component and the other end of the inclination measuring cartridge body is connected with a drum type buffer, and a flower type ring is sleeved in a radial direction of the inclination measuring cartridge body to achieve radial damping. The damping component can be one of the drum type buffer, a rubber rod and a damping pressure spring. The flower type ring is an elastic ring with pores at the edge. When the device is in a natural state, the drum type buffer and the flower type ring are tightly contacted with the inner wall of an anti-pressure cylinder at the outer side, and a certain gap is kept between an O-shaped ring and the inner wall of the anti-pressure cylinder. According to the combined damping system and device for the inclination measuring cartridge of the wireless drilling inclinometer, traditional axial one-dimensional damping is changed to be axial and radial two-dimensional damping by adopting an axial and radial combined damping method, therefore, the vibration-proof problem of the inclination measuring cartridge, particularly a high-precision quartz acceleration inclination measuring cartridge, in the well drilling process is solved well, thus the failure rate of the device under the well is greatly reduced; and the combined damping system and device for the inclination measuring cartridge of the wireless drilling inclinometer are applicable to damping of capacitance cartridges, cell cartridges and the like.

Description

technical field [0001] The invention relates to oil and gas field drilling technology, in particular to a combined damping method and a combined damping device of a wireless inclinometer while drilling an inclinometer sub-joint. Background technique [0002] The wireless inclinometer while drilling has the following features: 1) high efficiency - no need to frequently lift and release the instrument when connecting the drill pipe; 2) real-time performance - close to the drill bit, real-time monitoring of the position of the drill bit and drilling conditions; 3) after localization, use, The maintenance cost is greatly reduced; 4) The performance is increasingly stable and other advantages, so it has gradually replaced the original single-point, multi-point, wired while drilling and other inclinometers in the drilling operations of a large number of oil and gas wells at home and abroad, and has been widely used. . [0003] With the development of science and technology, the r...

Problems solved by technology

Once the instrument breaks down, the drill must be tripped again, and the instrument will be sent back to the manufacturer for maintenance. Therefore, each such failure will bring losses ranging from tens of thousands of yuan to hundreds of thousands of yuan to the construction unit.
