In order to achieve the above object, the technical scheme adopted by this utility model is：A kind of logging instrument erection device, including
Righting disc, body resistance-strengthening tablets, righting magnetic piece, regulation magnetic piece and righting sliding pallet.Described regulation magnetic piece is located at erection device center, adjusts
The central axis of magnetic piece and the central axes of erection device, adjust the bottom of magnetic piece by screw thread and the righting disc of lower end
Upper surface connects, and the both sides for adjusting magnetic piece are distributed with righting magnetic piece, and righting magnetic piece is connected with the body resistance-strengthening tablets in outside by screw thread, is helped
It is righting sliding pallet below positive, body resistance-strengthening tablets are connected with righting sliding pallet by screw thread.
The upper surface of described righting disc is radially provided with righting slideway, enables righting sliding pallet in righting slideway along footpath
To movement, the lower surface of righting disc is connected with logger by female thread.
Described body resistance-strengthening tablets, are shaped as semicylinder, and towards the borehole wall, body resistance-strengthening tablets are by screw thread and below for arc surface side
Righting sliding pallet connection.
Described regulation magnetic piece, is made up of magnetic core and regulating winding, and magnetic field is produced during energization, controls the work of erection device
State.
Described righting magnetic piece, positioned at magnetic piece both sides are adjusted, righting magnetic piece is made up of magnetic core and righting coil, righting coil
Electric current access direction it is contrary with regulating winding.
Active force between the magnetic field that this utility model is produced by righting magnetic piece and after adjusting magnetic piece energization is flexibly controlled
Erection device stretches, and when realizing that logger works, erection device opens, and makes logger placed in the middle；Logger is in pit shaft
During motion, erection device closure reduces righting pad wear, reduces logging cost.Whole device has a simple structure, small volume,
Can the eccentric problem of effectively solving inclined shaft Instrumental.

Fig. 2 is a kind of top view of logging instrument erection device of this utility model.
Fig. 3 is a kind of fundamental diagram of logging instrument erection device of this utility model.
Specific embodiment
Below in conjunction with the accompanying drawings structure and working principle of the present utility model is described in detail.
With reference to Fig. 1, a kind of logging instrument erection device, including righting disc 1, body resistance-strengthening tablets 2, righting magnetic piece 3, regulation 4 and of magnetic piece
Righting sliding pallet 5.Adjust magnetic piece 4 and be located at erection device center, adjust the central axis of magnetic piece 4 and the central axis weight of erection device
Close, the bottom for adjusting magnetic piece 4 is connected with the upper surface of the righting disc 1 of lower end by screw thread, adjust 4 both sides of magnetic piece and righting is distributed with
Magnetic piece 3, is body resistance-strengthening tablets 2 on the outside of righting magnetic piece 3, and body resistance-strengthening tablets 2 are connected with righting magnetic piece 3 by screw thread.The lower section of body resistance-strengthening tablets 2 is to help
Positive sliding pallet 5, body resistance-strengthening tablets 2 are connected with righting sliding pallet 5 by screw thread.Righting disc 1 is located at the bottom of erection device, under righting disc 1
Surface is connected with logger 7 by female thread.
With reference to Fig. 2, body resistance-strengthening tablets 2 are shaped as semicylinder, the arc surface of body resistance-strengthening tablets 2 towards outside, when body resistance-strengthening tablets 2 are stretched out with
The borehole wall 6 is contacted, and by increasing contact area, is strengthened righting intensity, is improved righting effect.
The upper surface of righting disc 1 is radially provided with righting slideway 8, and righting sliding pallet 5 is used cooperatively with righting slideway 8 so that
Righting sliding pallet 5 can be moved radially in righting slideway 8.
With reference to Fig. 3, adjust magnetic piece 4 and be made up of magnetic core 9 and regulating winding 10, righting magnetic piece 3 is by magnetic core 9 and righting coil 11
Constitute, the material of magnetic core 9 is ferrite, coil magnetic field magnetic can be improved, the electric current of regulating winding 10 accesses direction and righting
Coil 11 is contrary.
Operation principle of the present utility model and operating process：When logger 7 is moved in the wellbore, it is not necessary to during righting,
Electric current is passed through in magnetic piece 4 is adjusted, magnetic piece 4 is now adjusted and is produced magnetic field, attract both sides righting magnetic piece 3 under the influence of a magnetic field,
And then traction body resistance-strengthening tablets 2, move regulation magnetic piece 4 of the righting sliding pallet 5 at 8 Shang Xiang centers of righting slideway, realize erection device
Closure.When logger 7 reaches certain depth, stop movement, when preparing to measure the formation resistivity at the position, by righting magnetic
Block 3 and be passed through electric current simultaneously in adjusting magnetic piece 4, due to the electric current of righting magnetic piece 3 access direction with adjust magnetic piece 4 conversely, therefore
The electromagnetic field of generation is in opposite direction, causes righting magnetic piece 3 in the close side for adjusting magnetic piece 4 with identical polar, in this reality
Apply in example, with reference to Fig. 3, the righting magnetic piece 3 in left side is having an identical polar N poles near the side for adjusting magnetic piece 4, and right side is helped
Positive magnetic piece 3 has identical polar S poles near the side for adjusting magnetic piece 4.In the presence of same sex repulsive force, righting magnetic piece 3 is remote
From regulation magnetic piece 4, and then the righting sliding pallet 5 of connection body resistance-strengthening tablets 2 is promoted to slide to 6 direction level of the both sides borehole wall in righting slideway 8
It is dynamic, the stretching, extension of erection device is realized, uniform pressure, the purpose placed in the middle so as to reach instrument are applied to the borehole wall 6 by body resistance-strengthening tablets 2.
In sum, this utility model provides a kind of logging instrument erection device, with simple structure, the spy of small volume
Point, is not required to complicated control circuit, and using magnetic field electrode characteristic, flexibly control body resistance-strengthening tablets is flexible, reaches the purpose of instrument righting,
