Description
Technical field
This utility model belongs to well logging apparatus technical field, is related to a kind of 40 arm calliper log devices.
Background technology
Common caliper has three or four arms, and open be close to the borehole wall under the action of the spring by end for each arm.With well
The change in footpath, the end of arm also with opening or closing up, while driving potentiometer slider movement.Then the change of hole diameter is reformed into
The change of resistance.Existing caliper is suffered from the drawback that：Due to caliper each arm and the borehole wall between exist friction, so instrument
Sensor can wear and tear device in use, increased the maintenance capacity to instrument, shorten the service life of instrument；In measurement by
Fit with the borehole wall not closely in measurement arm, cause measurement data inaccurate.
Utility model content
The purpose of this utility model is to provide a kind of 40 arm calliper log devices, solves existing caliper and is using
During the problem that can wear and tear of sensor.
The technical scheme adopted by this utility model is：A kind of 40 arm calliper log devices, including shell, outside shell
Multiple measurement arms are provided with, and measurement arm end is provided with displacement transducer, and the tooth being fixedly connected with measurement arm is provided with shell
Wheel disc, toothed disc top toe joint have motor, motor afterbody to be provided with hydraulic cylinder.
The characteristics of this utility model, also resides in：
Shell top is provided with centralizer, and shell bottom is provided with lower centralizer.
Upper centralizer and lower centralizer are connected with toothed disc by fix bar.
Measurement arm is provided with 40.
Displacement transducer is non-contact displacement transducer.
Controller is provided with shell, and controller is connected with displacement transducer, hydraulic cylinder and motor by transmission line.
The beneficial effects of the utility model are：This utility model 40 arm calliper log devices of one kind, easy to use, stable
Degree is high and measuring accuracy is high, and the certainty of measurement of non-contact displacement transducer and sensitivity are all higher, while in instrument
During use, sensor does not wear and tear, and reduces the maintenance capacity to sensor, such that it is able to increase the service life of instrument；Separately
Outward, the apparatus structure is simple, low cost, it is easy to promote.
Description of the drawings
Fig. 1 is a kind of structural representation of 40 arm calliper log device of this utility model.
In figure, 1. shell, 2. measures arm, 3. toothed disc, 4. motor, and 5. hydraulic cylinder, 6. goes up centralizer, 7. descend righting
Device, 8. fix bar.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in detail.
A kind of 40 arm calliper log devices, as shown in Figure 1.Including shell 1, multiple measurement arms outside shell 1, are provided with
2,2 end of measurement arm is provided with displacement transducer, is provided with the toothed disc 3 being fixedly connected with measurement arm 2, toothed disc 3 in shell 1
Top toe joint has motor 4,4 afterbody of motor to be provided with hydraulic cylinder 5, and 1 top of shell is provided with centralizer 6, shell 1
Bottom is provided with lower centralizer 7, and upper centralizer 6 and lower centralizer 7 are connected with toothed disc 3 by fix bar 8, and measurement arm 2 is arranged
There are 40, displacement transducer is non-contact displacement transducer, in shell 1, be provided with controller, controller passes through transmission line
It is connected with displacement transducer, hydraulic cylinder 5 and motor 4.
During use, the device is put in well casing, upper centralizer 6 and lower centralizer 7 can realize the support to the borehole wall, is prevented
Stop the bias of shell, upper centralizer 6 and lower centralizer 7 can also receive the power of hydraulic cylinder 5 so as to fit with the borehole wall closely,
The bias of shell is further prevented；The device is moved along well casing inwall, and measurement arm 2 changes as well casing inwall changes,
By sensor acquisition variable quantity.
This utility model 40 arm calliper log devices of one kind, easy to use, degree of stability is high and measuring accuracy is high, non-connects
The certainty of measurement of touch displacement transducer and sensitivity are all higher, while sensor does not grind during instrument use
Damage, reduce the maintenance capacity to sensor, such that it is able to increase the service life of instrument；In addition, the apparatus structure is simple, cost
Low, it is easy to promote.
