Technical Field

The invention belongs to the technical field of oil and gas drilling, and particularly relates to a ground test system for the working characteristics of a double-pendulum speed-increasing drilling tool.

Background

In recent years, deep oil and gas resources are being developed vigorously in China, but deep drilling faces the bottleneck of speed increase of hard formations, and the problem is particularly prominent in the western new green jade area. For example, in the gravel rock and mudstone stratum with the depth of more than 4000 meters and the compact dolomite and mudstone stratum with the depth of more than 6000 meters, the stratum is hard, the drillability is poor, the mechanical drilling speed is low, the service life of a drill bit is short, and the acceleration of the deep well is severely restricted.

The breaking efficiency of the drill bit is the most direct factor affecting the drilling rate. In the drilling process of a hard stratum, a drill bit is subjected to vibration in all directions and is in a bouncing, swinging or whirling state, according to measured data provided by the American Smith company, the radial acceleration borne by the drill bit can reach 100-200G, the axial acceleration can reach 5-30G, and the instantaneous stress is converted into the impact force equivalent to 8 tons in the radial direction and 1.2 tons in the axial direction, so that the state of the drill bit is extremely unstable, cutting teeth cannot fully bite into the stratum, the service life of the drill bit is seriously influenced by vibration in all directions, and the drilling efficiency is greatly reduced.

The double-pendulum speed-increasing drilling tool actively inhibits radial vibration caused by vortex motion and jumping of a drill bit based on the high-speed gyroscope self-stability principle, weakens vibration acceleration, stabilizes the posture of the drill bit, realizes stable rock breaking, prolongs the service life of the drill bit and improves the rock breaking efficiency of the drill bit. The application of the gyrostabilization principle is wide, such as a gyroscopic balance damper of a skyscraper, a gyrostabilizer on a train or a ship and the like, which are used for relieving the vibration response of an object. The damping mechanism of the high-speed gyroscope is the angular momentum, namely the product of the rotational inertia and the rotating speed, the larger the angular momentum is, the more stable the rotating state is, and the better the damping effect is.

Therefore, the ground test system for the working characteristics of the double-pendulum speed-up drilling tool is provided for researching the working characteristics of the double-pendulum speed-up drilling tool, providing experimental data for optimizing and upgrading the tool, and realizing the working characteristics of the double-pendulum speed-up drilling tool under the conditions of different discharge capacities, different rotating speeds, different vibration displacements, different vibration forms and the like, and has important practical significance.
