[0037] Reference below Figures 1-6 Description The thermal insulation calibration device 100 according to an embodiment of the present invention has a simple structure, is easy to install, has high operational reliability, and can improve the thermal insulation effect of the measuring device, thereby ensuring the accuracy of the calibration result.

[0038] like Figures 1-6 As shown, a thermal insulation calibration device 100 according to an embodiment of the present invention includes: a fixed mounting seat 1, a vacuum thermal insulation component 2 and an inner thermal insulation component 3.

[0039] The vacuum insulation component 2 is installed on the fixed mounting base 1. The vacuum insulation component 2 is provided with a penetration space 25, and a vacuum cavity 24 is formed in the vacuum insulation component 2 around the penetration space 25. The inner insulation component 3 is inserted into the penetration space 25. The inner insulation component 3 is limited to the vacuum insulation component 2 along the insertion direction by a limiting component 35. An installation cavity 36 is formed in the inner insulation component 3, and the installation cavity 36 is used to install the measuring device.

[0040] During well logging, a probe equipped with measuring devices is lowered into the wellbore to measure bottomhole temperature, wellbore trajectory parameters, geological parameters, and more. The thermal insulation calibration device 100 can be used to measure and calibrate the accuracy and performance of measuring devices installed on the probe, such as temperature sensors or detectors, in high-temperature environments. Calibration is a key step in ensuring that the probe can accurately measure temperature during actual operation. Furthermore, to mitigate heat loss from the probe after high-temperature heating, the calibration device must be insulated.

[0041] Specifically, the thermal insulation calibration device 100 is provided with a fixed mounting seat 1, which can be set as a mounting frame or a mounting body and other structures, and the fixed mounting seat 1 can be set as aluminum alloy and other materials, and the setting flexibility is high. The thermal insulation calibration device 100 is also provided with a vacuum insulation component 2, which can be installed on the fixed mounting seat 1 through a connector or a snap connection. The vacuum insulation component 2 can maintain the required angle through the fixed mounting seat 1 to meet the use requirements. The vacuum insulation component 2 can be set as a cylindrical structure, and the vacuum insulation component 2 is provided with a penetration space 25. The penetration space 25 is formed in the middle of the vacuum insulation component 2 and extends along the circumference of the vacuum insulation component 2. The penetration space 25 is set axially through the vacuum insulation component 2.

[0042] Furthermore, the thermal insulation calibration device 100 is also provided with an inner thermal insulation component 3, which can also be set as a columnar structure, and the inner thermal insulation component 3 matches the penetration space 25 of the vacuum thermal insulation component 2, so that the inner thermal insulation component 3 can be inserted into the penetration space 25, and a vacuum cavity 24 is formed in the vacuum thermal insulation component 2, and the vacuum cavity 24 is arranged around the penetration space 25. When the inner thermal insulation component 3 is inserted into the penetration space 25, the vacuum cavity 24 can be arranged around the inner thermal insulation component 3. The vacuum cavity 24 is in a vacuum state, that is, the air pressure in the vacuum cavity 24 is low, so that the vacuum cavity 24 can reduce the frequency and intensity of collisions between gas molecules, and can prevent the occurrence of convection and contact, two forms of heat transfer, so that the vacuum thermal insulation component 2 can reduce the heat loss rate of the inner thermal insulation component 3 inserted in the penetration space 25, so as to insulate the inner thermal insulation component 3.

[0043] An installation cavity 36 is formed in the inner insulation component 3, and the installation cavity 36 can be used to install a measuring device. The measuring device can be set as a temperature sensor or detector, etc. The probe is also passed through the installation cavity 36, and the measuring device is installed on the probe. The inner insulation component 3 and the vacuum insulation component 2 can both be set to TA2 titanium alloy material. The thermal conductivity of TA2 titanium alloy material is low. Setting the inner insulation component 3 and the vacuum insulation component 2 to TA2 titanium alloy material can slow down the heat loss rate of the probe and the measuring device in the installation cavity 36, thereby ensuring the calibration accuracy of the probe and the measuring device, so as to improve the reliability of the insulation calibration device 100.

[0044] At the same time, the installation cavity 36, the penetration space 25 and the vacuum cavity 24 are all arranged to be coaxially distributed, so that the distance from the probe in the installation cavity 36 to any position in the vacuum cavity 24 is the same, and thus the thermal insulation calibration device 100 can have the same thermal insulation effect on the probe and the measuring device at all locations, thereby ensuring the reliability of the use of the thermal insulation calibration device 100.

[0045] In addition, the inner insulation component 3 can be provided with a limiting member 35, which is provided at one end of the inner insulation component 3 and can protrude outward along the outer peripheral wall of the inner insulation component 3. The inner insulation component 3 can be inserted into the penetration space 25 of the vacuum insulation component 2, and when the inner insulation component 3 is inserted into the penetration space 25, the limiting member 35 can be limited to the vacuum insulation component 2 along the insertion direction, so that the inner insulation component 3 can be movable relative to the vacuum insulation component 2 along the insertion direction, and can also be fixed relative to the vacuum insulation component 2 by the limiting member 35 after the insertion is completed. It has a simple structure, is easy to install, has high flexibility in use, and has low installation cost.

[0046] According to the thermal insulation calibration device 100 of the embodiment of the present invention, by setting a vacuum thermal insulation part 2 and an internal thermal insulation component 3, double-layer thermal insulation can be performed on the measuring device in the installation cavity 36 of the internal thermal insulation component to ensure the thermal insulation effect of the thermal insulation calibration device 100 on the measuring device, thereby ensuring the accuracy of the calibration result. In addition, the device has a simple structure, convenient installation, low setting cost, can ensure operational reliability, better use effect, and a wider range of applications.

[0047] In some embodiments, the vacuum insulation component 2 includes a vacuum inner cylinder 21 and a vacuum outer cylinder 22. The vacuum outer cylinder 22 is sleeved outside the vacuum inner cylinder 21 and is radially spaced apart from the vacuum inner cylinder 21. The end of the vacuum outer cylinder 22 is connected to the end of the vacuum inner cylinder 21 through an end plate 23 to jointly define a vacuum chamber 24.

[0048] Specifically, the thermal insulation calibration device 100 is provided with a vacuum thermal insulation component 2, and as Figure 4As shown, the vacuum insulation component 2 includes a vacuum inner cylinder 21 and a vacuum outer cylinder 22. The vacuum outer cylinder 22 is arranged at the outermost side of the vacuum insulation component 2, and the vacuum outer cylinder 22 can be sleeved outside the vacuum inner cylinder 21. The vacuum outer cylinder 22 and the vacuum inner cylinder 21 are both set to cylindrical structures. The radial dimension of the vacuum outer cylinder 22 is set to be larger than the radial dimension of the vacuum inner cylinder 21. When the vacuum outer cylinder 22 is sleeved outside the vacuum inner cylinder 21, the vacuum outer cylinder 22 is spaced apart from the vacuum inner cylinder 21 in the radial direction. The ends of the vacuum inner cylinder 21 and the vacuum outer cylinder 22 can be connected by an end plate 23, so that the vacuum outer cylinder 22, the end plate 23 and the vacuum inner cylinder 21 can jointly define an annular cylindrical vacuum cavity 24, and a penetration space 25 for plugging in the inner insulation component 3 can be defined in the vacuum inner cylinder 21, so that the vacuum cavity 24 can be arranged around the penetration space 25.

[0049] Furthermore, the vacuum outer cylinder 22 is sleeved on the outside of the vacuum inner cylinder 21 and is distributed radially at intervals. The vacuum outer cylinder 22 and the vacuum inner cylinder 21 are coaxially arranged, so that the distance between each point of the outer wall of the vacuum inner cylinder 21 and each point of the inner wall of the vacuum outer cylinder 22 is the same. A vacuum cavity 24 is defined between the vacuum inner cylinder 21 and the vacuum outer cylinder 22, so that the cavity thickness of the vacuum cavity 24 is the same at each point, thereby ensuring that the thermal insulation effect of the vacuum insulation component 2 is the same at each point, so as to ensure the reliability of the use of the vacuum insulation component 2, and the vacuum inner cylinder 21, the vacuum outer cylinder 22 and the end plate 23 are all set to TA2 titanium alloy material, which has a low thermal conductivity and can thereby improve the thermal insulation effect of the vacuum insulation component 2.

[0050] In some embodiments, the vacuum outer cylinder 22 is provided with a mounting hole communicating with the vacuum chamber 24 , and the mounting hole is used for mounting the regulating valve 221 .

[0051] Specifically, the vacuum outer cylinder 22 is sleeved outside the vacuum inner cylinder 21, and the vacuum outer cylinder 22, the end plate 23 and the vacuum inner cylinder 21 together define a vacuum cavity 24 to improve the heat preservation effect of the vacuum heat preservation element 2. Figure 1-Figure 2 As shown, the vacuum outer cylinder 22 is provided with a mounting hole, which is arranged to penetrate the vacuum outer cylinder 22 radially so that the mounting hole can be connected to the vacuum chamber 24, and the mounting hole is used to install the regulating valve 221. The mounting hole can be set as a threaded hole, and the outer peripheral wall of the regulating valve 221 can also be provided with a thread, so that the regulating valve 221 can be matched with the mounting hole thread, which is convenient for installation.

[0052] Furthermore, the regulating valve 221 can be set as an SMC speed regulating throttle valve, etc. After the vacuum cavity 24 is defined between the vacuum outer cylinder 22, the end plate 23 and the vacuum inner cylinder 21, the vacuum cavity 24 can be evacuated through the regulating valve 221 on the outside of the vacuum insulation component 2 to ensure the vacuum state in the vacuum cavity 24. In actual setting, the mounting hole can also be set on the end plate 23 to install the regulating valve 221 on the end plate 23, which has high setting flexibility.

[0053] In other embodiments, the vacuum outer cylinder 22 is provided with a heat-insulating cotton 5, the inner heat-insulating component 3 is inserted into the penetration space 25, and the vacuum heat-insulating component 2 is provided with a vacuum cavity 24, which can insulate the probe and the measuring device in the installation cavity 36, and Figure 1-Figure 2 As shown, the outer side of the vacuum outer cylinder 22 can be provided with thermal insulation cotton 5, and the thermal insulation cotton 5 can be set to glass wool, etc., that is, the thermal insulation cotton 5 can insulate the vacuum insulation component 2 again to enhance the thermal insulation effect of the thermal insulation calibration device 100 and improve the reliability of the thermal insulation calibration device 100.

Figure 5-Figure 6 As shown, the inner insulation component 3 is provided with a connecting plug 31, an inner insulation tube 32 and a straightening structure 34. The connecting plug 31, the inner insulation tube 32 and the straightening structure 34 can all be set to TA2 titanium alloy material. The thermal conductivity of TA2 titanium alloy material is relatively low, which can improve the insulation effect of the inner insulation component 3. The connecting plug 31, the inner insulation tube 32 and the straightening structure 34 can jointly define an installation cavity 36, that is, the installation cavity 36 is formed in the inner insulation tube 32, and the probe and the measuring device are installed in the installation cavity 36, so that the probe and the measuring device can be insulated, thereby ensuring the reliability of high-temperature calibration of the probe and the measuring device.

[0056] The connecting plug 31 is connected to one end of the inner heat-insulating tube 32 and at least partially extends into the installation cavity 36 , and the straightening structure 34 is connected to the other end of the inner heat-insulating tube 32 and at least partially extends into the installation cavity 36 .

[0057] Specifically, if Figure 5-Figure 6 As shown, the connecting plug 31 and the straightening structure 34 are respectively installed at the two ends of the inner insulation tube 32, that is, the connecting plug 31 can be connected to one end of the inner insulation tube 32, and the straightening structure 34 can be connected to the other end of the inner insulation tube 32. At least a portion of the connecting plug 31 extends into the installation cavity 36, and a socket 6 is installed at the end of the connecting plug 31 extending into the installation cavity 36. The socket 6 can be used to install measuring devices, etc. At least a portion of the straightening structure 34 can also extend into the installation cavity 36, so that the probe can pass through the connecting plug 31 and the straightening structure 34 respectively, so that the probe is located in the middle of the installation cavity 36, ensuring the insulation effect of various parts of the probe and ensuring the reliability of the inner insulation component 3.

[0058] In some embodiments, a limit member 35 is provided at one end of the straightening structure 34, or a limit member 35 is provided between the connecting plug 31 and one end of the inner insulation tube 32, wherein the limit member 35 protrudes radially outward from the outer peripheral wall of the inner insulation tube 32.

[0059] Specifically, the inner insulation component 3 is provided with a limit member 35, which is provided at both ends of the inner insulation component 3, and the two ends of the inner insulation component 3 are respectively provided with a connecting plug 31 and a straightening structure 34, so that the limit member 35 can be as Figure 5 As shown, it is arranged at the end of the straightening structure 34 away from the inner heat preservation tube 32, and can also be as shown in FIG. Figure 6 As shown, the limiter 35 is arranged between the connecting plug 31 and one end of the inner insulation tube 32. The limiter 35 can be set as an annular structure, and the limiter 35 protrudes radially outward from the outer peripheral wall of the inner insulation tube 32, so that when the inner insulation component 3 is inserted into the penetration space 25, the limiter 35 can be limited to the end of the vacuum insulation component 2.

[0060] Furthermore, when the limiter 35 is installed at the end of the straightening structure 34 away from the inner insulation tube 32, the end of the inner insulation component 3 away from the limiter 35 can be placed in the penetration space 25 first, and the inner insulation component 3 can be plugged into the vacuum insulation component 2 under the action of gravity until the limiter 35 is pressed against the end of the vacuum insulation component 2, and when the limiter 35 is installed between the connecting plug 31 and one end of the inner insulation tube 32, the end of the inner insulation component 3 away from the limiter 35 can be placed in the penetration space 25 first, and the inner insulation component 3 can be plugged into the vacuum insulation component 2 under the action of gravity until the limiter 35 is pressed against the end of the vacuum insulation component 2.

[0061] In this way, the limit members 35 can be installed at both ends of the inner insulation component 3 according to usage requirements, so that when the inner insulation component 3 is inserted into the vacuum insulation component 2, the end of the inner insulation component 3 provided with the connecting plug 31 is facing upward, or the end of the inner insulation component 3 provided with the straightening structure 34 is facing upward, thereby meeting different usage requirements and improving usage flexibility. The limit member 35 is used for limiting installation, which is convenient to install, simple in structure, and can reduce the installation cost.

[0064] The connecting plug 31 can be pressed against one end of the pressure-resistant tube 33 and the inner insulation tube 32, and the straightening structure 34 can be pressed against the other end of the pressure-resistant tube 33 and the inner insulation tube 32 to ensure the installation stability of the pressure-resistant tube 33 and the inner insulation tube 32, thereby ensuring the calibration reliability of the probe and measuring device.

[0065] In other embodiments, the inner insulation tube 32 is provided with a plurality of pressure-reducing holes, and the pressure-reducing holes are set to be multiple, that is, the pressure-reducing holes can be set to two, three or four, etc. In this embodiment, the pressure-reducing holes are set to ten, and the ten pressure-reducing holes are evenly spaced along the axial direction of the inner insulation tube 32. The inner insulation tube 32 is sleeved on the outside of the pressure-resistant tube 33. Since the material will expand after being heated, providing a plurality of pressure-reducing holes in the inner insulation tube 32 can reduce deformation or stress concentration caused by thermal expansion, and achieve more uniform heat distribution, thereby ensuring the calibration reliability of the probe and measuring device.

[0066] In some embodiments, the righting structure 34 includes a righting frame 341, a sleeve 342 and a threaded sleeve 343.

The threaded sleeve 343 is connected to the end of the righting frame 341 away from the installation cavity 36, and the threaded sleeve 343 is pressed against the sleeve 342, or a limiting member 35 is provided between the threaded sleeve 343 and the sleeve 342.

[0067] Specifically, the straightening structure 34 is connected to one end of the inner heat-insulating cylinder 32, and Figure 5-Figure 6 As shown, the straightening structure 34 includes a straightening frame 341, a shaft sleeve 342 and a threaded sleeve 343. The straightening frame 341 is connected to the end of the pressure-resistant cylinder 33 by means of threaded fitting, and at least part of the straightening frame 341 extends into the installation cavity 36, so that the straightening frame 341 and the connecting plug 31 can be used together to pass the probe tube, so that the probe tube is located in the middle of the installation cavity 36, ensuring the thermal insulation effect of all parts of the probe tube.

The fixing part 12 can be connected to the mounting bracket 11 by welding or a connecting part 4, etc., and the vacuum insulation part 2 can be fixedly installed on the fixing part 12, so that the vacuum insulation part 2 can be fixedly installed on the fixed mounting seat 1.

[0072] Further, if Figure 3 As shown, the fixing member 12 is provided with a lower fixing seat 121 and an upper fixing seat 122. The lower fixing seat 121 can be connected to the mounting bracket 11 through a connecting member 4, and the upper fixing seat 122 can also be connected to the lower fixing seat 121 through a connecting member 4. The connecting member 4 can be set as a bolt, etc., which is simple to install and has low installation cost. The lower fixing seat 121 and the upper fixing seat 122 are both formed with a clamping groove recessed away from each other. When the upper fixing seat 122 and the lower fixing seat 121 are connected through the connecting member 4, the two clamping grooves can jointly define a clamping space, and the vacuum insulation member 2 can be placed in the clamping space so that the vacuum insulation member 2 is fixedly installed between the lower fixing seat 121 and the upper fixing seat 122.

[0073] In this way, the upper fixing seat 122 and the lower fixing seat 121 are connected by the connecting piece 4, so that the upper fixing seat 122 is detachable relative to the lower fixing seat 121, which is convenient for later maintenance, saving disassembly and installation time, and the upper fixing seat 122 and the lower fixing seat 121 are connected by the connecting piece 4, so that the size of the clamping space between the upper fixing seat 122 and the lower fixing seat 121 is adjustable, so that the fixing piece 12 can be suitable for vacuum insulation parts 2 of different sizes to meet different usage requirements.

[0074] In some embodiments, the mounting bracket 11 includes a base plate 112 and two mounting plates 111, the upper ends of the two mounting plates 111 are connected and the lower ends are respectively connected to the two ends of the base plate 112, and the two mounting plates 111 are provided with fixing parts 12, wherein the vacuum insulation parts 2 are set as two, and the two vacuum insulation parts 2 are respectively installed on the two mounting plates 111.

[0075] Specifically, the fixed mounting seat 1 is provided with a mounting bracket 11 and a fixing member 12, and as shown in FIG. Figure 3 As shown, the mounting bracket 11 is provided with a base plate 112 and two mounting plates 111. The base plate 112 is arranged at the bottom of the mounting bracket 11, and the upper ends of the two mounting plates 111 can be connected by welding or the like. The lower ends of the two mounting plates 111 can be connected to the base plate 112 by welding or the like. The lower ends of the two mounting plates 111 are spaced apart and distributed, so that the two mounting plates 111 and the base plate 112 can jointly construct a triangular bracket, thereby improving the stability of the mounting bracket 11, and the two mounting plates 111 and the base plate 112 are both provided with a support plate 113. The support plate 113 can improve the structural strength of the two mounting plates 111 and the base plate 112, and can support between two adjacent plates, further improving the structural stability of the mounting bracket 11, so as to improve the reliability of the mounting bracket 11.

[0076] Furthermore, both mounting plates 111 are provided with fixing parts 12, which are used to fix the vacuum insulation parts 2, so that both mounting plates 111 can be installed with vacuum insulation parts 2. In actual settings, two vacuum insulation parts 2 can be set, and the two vacuum insulation parts 2 can be installed on the two mounting plates 111 respectively. The internal insulation component 3 is set as one, and one internal insulation component 3 can be respectively inserted into the penetration space 25 of the two vacuum insulation parts 2 according to usage requirements, so that there are two installation angles between the internal insulation component 3 and the bottom plate 112, so as to meet the well inclination angle required for high-temperature calibration of the probe.

[0077] In actual setting, each mounting plate 111 may be provided with one or two fixing members 12. In this embodiment, Figure 1-Figure 3 As shown, each mounting plate 111 is provided with two fixing members 12 , and the two fixing members 12 can sandwich a vacuum thermal insulation member 2 together to ensure the reliability of the installation of the vacuum thermal insulation member 2 .

[0078] In some embodiments, an included angle is formed between the two mounting plates 111 and the bottom plate 112 , and the two included angles are set to a and b respectively, and satisfy: a=b=45°.

[0079] Specifically, the upper ends of the two mounting plates 111 are connected, and the lower ends of the two mounting plates 111 are respectively connected to the base plate 112, so that the two mounting plates 111 and the base plate 112 can jointly form a triangular bracket, and the two mounting plates 111 can be set to be equal in length, so that the angles between the two mounting plates 111 and the base plate 112 are equal, and angles are formed between the two mounting plates 111 and the base plate 112, and the two angles are set to a and b respectively. When the lengths of the mounting plates 111 are set to be equal, a and b are equal, and the two angles a and b formed between the two mounting plates 111 and the base plate 112 satisfy: a=b=45°.

[0080] In this way, when the limiter 35 is installed between the threaded sleeve 343 and the shaft sleeve 342, the end of the inner insulation component 3 away from the limiter 35 can be placed in the penetration space 25 first, and the inner insulation component 3 can be plugged into the vacuum insulation component 2 under the action of gravity until the limiter 35 is pressed against the end of the vacuum insulation component 2. At this time, a 45° angle is formed between the inner insulation component 3 and the bottom plate 112, so that the probe and measuring device in the installation cavity 36 can meet the well inclination angle required for high-temperature calibration.

[0081] And when the limiter 35 is installed between the connecting plug 31 and one end of the inner insulation tube 32, the end of the inner insulation component 3 away from the limiter 35 can be placed in the penetration space 25 first, and the inner insulation component 3 can be plugged into the vacuum insulation component 2 under the action of gravity until the limiter 35 is pressed against the end of the vacuum insulation component 2. At this time, an angle of 135° is formed between the inner insulation component 3 and the bottom plate 112, so that the probe and measuring device in the installation cavity 36 can meet the well inclination angle required for high-temperature calibration and meet different usage requirements.

[0082] In addition, during actual setting, the length of the two mounting plates 111 can be adjusted to adjust the size of the angle between the two mounting plates 111 and the bottom plate 112, so that the thermal insulation calibration device 100 can meet different well inclination angles and increase the scope of use.
