The utility model discloses multi-arm caliper gyro continuous meters, including shell and the circuit board of inside, the shell to be provided with heat-barrier material filled layer and vacuum layer, and circuit board is additionally provided with temperature sensor.By the way that heat-barrier material filled layer and vacuum layer are arranged in the shell of logging instrument, so that it is guaranteed that the environment temperature of system work is not increased with the raising of ambient temperature, it is heat-insulated by two layers of two layers of heat-barrier material filled layer and vacuum layer, so that heat insulation is more preferable, to ensure that instrument works normally for a long time, it crosses setting temperature sensor to monitor its internal temperature in real time, ensures operating ambient temperature, ensure accurate data；It solves since the temperature in stratum is for the influence to instrument, to ensure the normal continuous work of logging instrument system, instrument also needs other is taken to handle and carries out working environment stabilization to it while selecting high temperature resistant optical device, it is ensured that the problem of its instrument will not be by ectocine.
Description
Technical field
The utility model is related to logging instruments, and in particular to multi-arm caliper gyro continuous meter.
Background technology
Oil gas well bore track measurement in, logging instrument be influenced by temperature it is bigger, and the temperature of oil well environment become
Change it is bigger, so fibre optic gyroscope work most important problem be high temperature problem.Since the temperature gradient in stratum is about 3
DEG C/100m, then about 90~150 DEG C of the oil well temperature of 3000~5000m, for ultradeep well temperature then can higher, to ensure
The normal continuous work of logging instrument system, instrument also need to take other to handle pair while selecting high temperature resistant optical device
It carries out working environment stabilization, it is ensured that its instrument will not be by external influence.
Utility model content
Technical problem to be solved in the utility model is：Since the temperature gradient in stratum is about 3 DEG C/100m, then
About 90~150 DEG C of the oil well temperature of 3000~5000m, for ultradeep well temperature then can higher, for ensure logging instrument system
Normal work, for instrument while selecting high temperature resistant optical device, also needing to take other to handle, to carry out working environment to it steady
It is fixed, it is ensured that the problem of its instrument will not be by ectocine, the utility model provide the multi-arm caliper top to solve the above problems
Spiral shell continuous meter.
The utility model is achieved through the following technical solutions：
Multi-arm caliper gyro continuous meter, including shell and the circuit board of inside, the shell are provided with heat-insulated material
Expect filled layer and vacuum layer.To solve the above problems, by the shell of logging instrument be arranged heat-barrier material filled layer and
Vacuum layer passes through two layers of heat-barrier material so that it is guaranteed that the environment temperature of system work is not increased with the raising of ambient temperature
Two layers of filled layer and vacuum layer are heat-insulated so that heat insulation is more preferable, to ensure that instrument works normally for a long time, solves due to stratum
In temperature gradient be about 3 DEG C/100m, then about 90~150 DEG C of the oil well temperature of 3000~5000m, for ultradeep well temperature
Degree then can higher, for ensure logging instrument system normal continuous work, instrument while selecting high temperature resistant optical device, and also
Other need to be taken to handle, working environment stabilization is carried out to it, it is ensured that the problem of its instrument will not be by ectocine.
Further, circuit board is additionally provided with temperature sensor.Its internal temperature is carried out by the way that temperature sensor is arranged
Monitoring in real time ensures operating ambient temperature, ensures accurate data.
Further, temperature sensor is AD590.
Further, the material of heat-barrier material filled layer filling is aerogel blanket.Aerogel blanket feature is thermal coefficient
It is low, there are certain tension and compression strength, is convenient for heat preservation construction application.
Further, internal layer of the vacuum layer in lagging casing.
The utility model has the following advantages and advantages：
1, the utility model is in the shell of logging instrument by being arranged heat-barrier material filled layer and vacuum layer, so that it is guaranteed that
The environment temperature of system work is not increased with the raising of ambient temperature, passes through two layers of heat-barrier material filled layer and vacuum layer two
Layer is heat-insulated so that heat insulation is more preferable, and to ensure that instrument works normally for a long time, solution is about due to the temperature gradient in stratum
3 DEG C/100m, then about 90~150 DEG C of the oil well temperature of 3000~5000m, for ultradeep well temperature then can higher, to ensure
The normal continuous work of logging instrument system, instrument also need to take other to handle pair while selecting high temperature resistant optical device
It carries out working environment stabilization, it is ensured that the problem of its instrument will not be by ectocine；
2, the utility model monitors its internal temperature by the way that temperature sensor is arranged in real time, ensures working environment temperature
Degree ensures accurate data；
3, the utility model aerogel blanket feature is that thermal coefficient is low, there is certain tension and compression strength, convenient for heat preservation
Construction application.
