Problems solved by technology

[0002] Measurement while drilling means that the drilling rig continuously detects the information about the drill hole and the drill bit while drilling. When it goes deep into the bottom of the well, hanging objects such as ropes are used to place them underground. The measuring instruments are slightly affected by the bottom pressure, and ropes and other objects cannot Let the measuring instrument move and turn, and perform multi-point measurement through a horizontal plane, the diversity of data is not enough, and the accuracy of data is poor

Embodiment

[0027] see Figure 1-Figure 7 , the present invention provides a two-way balancer for wireless measurement while drilling. Its structure includes a motor 1, a top plate 2, a brace 3, a chassis 4, and an adjuster 5. It is a flat cylinder structure, the diameter of the top plate 2 is smaller than the diameter of the chassis 4, the center of gravity is lowered, and it is relatively stable when entering the bottom of the well. The outer edges of the top plate 2 and the chassis 4 are mechanically connected by more than two diagonal braces 3, so The motor 1 is embedded in the middle of the top plate 2, the chassis 4 is a structure welded by an annular iron ring and a straight bar welded in the middle of it, and the adjuster 5 is installed in the middle of the straight bar and connected with the The motor 1 is on the same axis, and the regulator 5 cooperates with the motor 1 .

[0028] The regulator 5 includes an engaging shaft 51, a first half cylinder 52, a measuring instrument 53...

Abstract

The invention discloses a two-way balancer for wireless measurement while drilling. The balancer structurally comprises a motor, a top plate, an inclined support, a base plate and a regulator, the topplate is located over the base plate, the top plate and the base plate are all of a flat column structure, the diameter of the top plate is smaller than the diameter of the base plate, the gravity center is reduced, and the top plate enters a well bottom stably. The motor is used for controlling moving and steering of a measuring instrument, a counterweight half-column is needed for balance in the moving and steering processes, and the measuring instrument is kept in the same horizontal plane all the time; when wind force is generated due to the bottom layer pressure, if the wind force borneby the base plate is not uniform, blades can rotate to adjust the position of a ball to be balanced, so that the measuring instrument is kept stable, and measurement of the measuring instrument is notaffected.

Description

technical field [0001] The invention relates to the field of wireless measurement while drilling, in particular to a two-way balancer for wireless measurement while drilling. Background technique [0002] Measurement while drilling means that the drilling rig continuously detects the information about the drill hole and the drill bit while drilling. When it goes deep into the bottom of the well, hanging objects such as ropes are used to place them underground. The measuring instruments are slightly affected by the bottom pressure, and ropes and other objects cannot Let the measuring instrument move and turn, and perform multi-point measurement through a horizontal plane, the diversity of data is not enough, and the accuracy of data is poor. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention is realized through the following technical solutions: a two-way balancer for wireless measurement while drilling, its structure inclu...
