Abstract
The utility model discloses high temperature magnetic orientator single-core cable head harness, including the control system being arranged in shell, inner cavity, control system is additionally provided with baroceptor and temperature sensor, and heat-barrier material filled layer is additionally provided on the shell, and the inner cavity is vacuum chamber.Using thermal insulation layer is arranged on the shell, 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 heat-barrier material filled layer and vacuum chamber, so that heat insulation is more preferable, to ensure that instrument works normally for a long time, it solves due to the temperature gradient in stratum to be about 3 DEG C/100m, then about 90~150 DEG C of the oil well temperature of 3000~5000m, it then can higher for ultradeep well temperature, to ensure the normal work of optical fibre gyro system, instrument is while selecting high temperature resistant optical device, it also needs other is taken to handle and working environment stabilization is carried out to it, ensure the problem of its precision will not be by external influence.
Description
Technical field
The utility model is related to magnetic orientator cable head harness, and in particular to a kind of high temperature magnetic orientator single-core cable horse cage
Head.
Background technology
Since the temperature gradient in stratum is about 3 DEG C/100m, then the oil well temperature about 90~150 of 3000~5000m
DEG C, for ultradeep well temperature then can higher, for ensure system normal work, instrument select high temperature resistant optical device it is same
When, it also needs other is taken to handle working environment stabilization is carried out to it, it is ensured that its precision 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 system it is normal
Work, instrument also need other is taken to handle and carry out working environment stabilization to it while selecting high temperature resistant optical device, it is ensured that
The problem of its precision will not be by external influence, the utility model provide the high temperature magnetic orientator single to solve the above problems
Cable head harness.
The utility model is achieved through the following technical solutions：
High temperature magnetic orientator single-core cable head harness, including the control system that is arranged in shell, inner cavity, on the shell also
It is provided with heat-barrier material filled layer, the inner cavity is vacuum chamber.To solve the above problems, using thermal insulation layer is arranged on the shell,
So that it is guaranteed that the environment temperature of system work is not increased with the raising of ambient temperature, pass through heat-barrier material filled layer and vacuum
Chamber 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 work of optical fibre gyro system, instrument while selecting high temperature resistant optical device, also need to take other handle to its into
Row working environment is stablized, it is ensured that the problem of its precision will not be by external influence.
Further, control system is additionally provided with baroceptor and temperature sensor.By the way that baroceptor is arranged
And temperature sensor comes the air pressure inside detecting instrument and temperature, can be detected to the operating status of instrument, it is convenient
The use of instrument.
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.
The utility model has the following advantages and advantages：
1, the utility model using thermal insulation layer is arranged on the shell, so that it is guaranteed that the environment temperature of system work is not with outer
The raising of boundary's temperature and increase, it is heat-insulated by heat-barrier material filled layer and vacuum chamber so that heat insulation is more preferable, to ensure instrument
It works normally for a long time, solves due to the temperature gradient in stratum to be about 3 DEG C/100m, then the oil well temperature of 3000~5000m
About 90~150 DEG C of degree, for ultradeep well temperature then can higher, to ensure the normal work of optical fibre gyro system, instrument selecting
It while high temperature resistant optical device, also needs other is taken to handle working environment stabilization is carried out to it, it is ensured that its precision will not be by
The problem of external influence；
2, the utility model by be arranged baroceptor and temperature sensor come inside detecting instrument air pressure and
Temperature can be detected the operating status of instrument, facilitate the use of instrument；
3, the utility model aerogel blanket feature is that thermal coefficient is low, there is certain tension and compression strength, convenient for heat preservation
