The subsurface measuring device with the temperature control device can be used in high temperature geological environments and ice-cold geological environments.
Description
Affiliated technical field
The device for subsurface measuring and the various geological sciences that the invention belongs to oil, coal bed gas equal energy source are investigated the measuring apparatus field, are specially device for subsurface measuring temperature-controlled process and device.
Background technology
At present, known various device for subsurface measuring mainly is made up of measure portion and resistance to compression vibration damping shell, the attemperating unit that self internal temperature is regulated not, because the difference of geology and well depth, downhole temperature is also different thereupon, some special geology environment temperatures are very high, make various device for subsurface measuring normally to move.
Summary of the invention
In order to overcome the deficiency that existing device for subsurface measuring can not use under the high temperature extreme environment, the invention provides a kind of device for subsurface measuring temperature control method and device.
The technical solution adopted for the present invention to solve the technical problems is: the measure portion of device for subsurface measuring is sealed in the thermal insulation tube (being made of heat insulating material), thermoregulator, temperature pick up, temperature controller are housed in the thermal insulation tube, connect with circuit respectively, power by the device for subsurface measuring power supply.The temperature data that temperature pick up is gathered in the thermal insulation tube is transferred to temperature controller, temperature controller is according to the operation of default temperature value scope control thermoregulator, when the temperature value in the heat-preservation cylinder during greater than the default temperature upper limit of temperature controller, thereby temperature controller is started working to thermoregulator power supply control thermoregulator, temperature pick up keeps connecting the temperature data in electric work state and the continuous collecting thermal insulation tube, when temperature in the thermal insulation tube returns to the default temperature value scope of controller, thereby temperature controller stops to the thermoregulator power supply thermoregulator being quit work.Otherwise when the temperature in the insulating layer was lower than the default temperature range lower limit of temperature controller, temperature controller was powered to thermoregulator, thereby thermoregulator is got back to preset temperature range to heating the temperature that makes in the insulating layer in the insulating layer.
The invention has the beneficial effects as follows, can carry out adjustment, thereby device for subsurface measuring can be used in extreme temperatures or extremely low environment the measure portion of device for subsurface measuring.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.

In Fig. 1, temperature pick up (3) is powered by the device for subsurface measuring power supply with temperature controller (2), temperature pick up (3) is measured temperature, transfer data to temperature controller (2), temperature controller (2) treatment temperature data, again temperature value is compared with the temperature range value that sets, if the value of going beyond the scope, certain electric current and voltage is provided then for thermoregulator (1), at this moment thermoregulator (1) is started working, measure the ambient temperature value in the scope of the set definite value of temperature controller (2) time up to temperature pick up (3), temperature controller (2) stops to provide voltage and electric current to thermoregulator (1).
In embodiment illustrated in fig. 2, thermal insulation tube (5) is contained in the resistance to compression vibration damping shell (6), measure portion (4) is contained in the thermal insulation tube (5), the top of conductor temperature adjuster (1) is positioned at thermal insulation tube (5), the bottom is positioned at outside the thermal insulation tube (5), and contact with resistance to compression damper cylinder (6), thermoregulator (1) and temperature controller (2) are contained in the thermal insulation tube (5).
In Fig. 3, the bottom of a N-type semiconductor (1) and a P-type semiconductor (2) (it is outer to be positioned at the thermal insulation tube) is connected, top (being positioned at the thermal insulation tube) disconnects, form a group, first group P-type semiconductor is connected with second group N-type semiconductor, second group P-type semiconductor is connected with the 3rd group N-type semiconductor, draw with lead respectively on first group N-type semiconductor and the 3rd group of P-type semiconductor top, power line as the conductor temperature adjuster, be connected to form cold junction and hot junction with the insulating heat-conductive member respectively on semi-conductive top and bottom, three groups of semiconductors are composed in series a conductor temperature adjuster.The method that more semiconductor series, parallel or connection in series-parallel can be combined obtains more powerful conductor temperature adjuster as required.
When the temperature controller in the thermal insulation tube records temperature and is higher than set definite value by temperature pick up, temperature controller provides the voltage and the electric current of certain orientation for the conductor temperature adjuster, make the end of conductor temperature adjuster in the thermal insulation tube freeze, the outer end of thermal insulation tube heats, heat the resistance to compression vibration damping shell of end, heat is discharged outside the measuring apparatus the heat transferred device for subsurface measuring; When temperature controller records temperature in the thermal insulation tube and is lower than the temperature value that sets by temperature pick up, temperature controller provides electric current when direction is opposite when freezing for the conductor temperature adjuster, the end of conductor temperature adjuster this moment in the thermal insulation tube heats, the end refrigeration that the thermal insulation tube is outer.When temperature controller records temperature in the thermal insulation tube and is in the established temperature value by temperature pick up, stop to the power supply of conductor temperature adjuster, the conductor temperature adjuster quits work.
