Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling, in particular to a near-drill-bit shock-absorbing structure. Background Art

[0002] Oil drilling is powered by a ground rig, and the drill tool transmits torque and downward pressure. The torque and pressure break the rock through the drill bit to achieve downward drilling. Therefore, impact and bounce occur when the drill bit breaks the rock. This impact and bounce can cause fatal damage to the drilling instruments, and the closer to the drill bit, the greater the force. Therefore, the accident rate of instruments near the drill bit is the highest, which can easily cause irreversible damage to the instruments near the drill bit, increase the number of times the drill is pulled out to replace the instrument, and cause great economic losses to the instrument supplier and the production operation well team.

[0003] There are currently three solutions to this practical problem: 1. Reduce drilling speed and vibration; 2. Improve the anti-vibration ability of electronic components; 3. Increase shock absorption. Among the current solutions, the first method has the best effect, but reducing the drilling speed is inconsistent with actual production and wastes time; the second method increases the production cost of electronic components and has limited anti-vibration ability; the third method is currently the most commonly used method, but the actual application effect is not obvious. The shock absorption effect can be passed in the laboratory, but the same problem will still occur when it is actually used on site. Utility Model Content
