Description

Technical Field

[0001] This invention relates to the field of gas storage facilities, specifically to a wellbore temperature measuring device. Background Technology

[0002] A gas storage facility is a facility used to store natural gas, typically to balance the supply and demand of natural gas, especially during peak demand periods or times of supply shortage. Gas storage facilities help ensure a stable energy supply and act as a buffer against energy price fluctuations. When storing natural gas in a gas storage facility, the injection and recovery of natural gas usually requires a wellbore. The wellbore structure typically consists of a wellhead, casing, production tubing, and packers. Furthermore, to improve the safety of the gas storage facility, it is usually necessary to monitor the gas injected into the storage facility.

[0003] Existing technology, such as the Chinese patent application CN119333111A, discloses a wellbore temperature measuring device, which includes a controller, a data acquisition part, a counterweight part, and a connecting part for connecting the data acquisition part and the counterweight part, wherein the data acquisition part is electrically connected to the controller. The connecting part includes an outer sleeve, an inner sleeve, and a connector. The diameter of the outer sleeve is larger than the diameter of the inner sleeve. Both the outer sleeve and the inner sleeve are fixedly connected to the bottom of the collection part, and the inner sleeve is located inside the outer sleeve. A connecting post is fixedly connected to the top of the counterweight part, and the connecting post is inserted into the inner sleeve. The end of the outer sleeve away from the collection part abuts against the top of the counterweight part. The outer sleeve sidewall has two opposite locations, the inner sleeve sidewall has two opposite locations, and the connecting post has corresponding and communicating mounting holes. The connector passes through the mounting holes and is installed on the outer sleeve, the inner sleeve, and the connecting post. The bottom of the collection section is provided with an installation groove, in which an electrically controlled gate is installed. The electrically controlled gate is located on one side of the connector and divides the inner cavity of the outer sleeve into a reaction chamber and a storage chamber. The connector is located in the reaction chamber, and the storage chamber stores strong acid. The electrically controlled gate is electrically connected to the controller. When the controller controls the electrically controlled gate to open, the electrically controlled gate retracts towards the bottom of the installation groove, and the strong acid enters the reaction chamber to corrode and dissolve the connector.

[0004] Current temperature measurement methods involve placing a detection device inside the well casing to measure the internal temperature. However, this method cannot accurately detect the temperature of the gas flowing inside the pipeline, resulting in inaccurate detection results. Furthermore, the use of strong acids or other equipment during the detection process damages the internal structure of the well casing, which is not only extremely dangerous but also very inconvenient for subsequent repairs. Finally, existing technologies leave residual structures inside the well casing during detection, causing contamination. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a wellbore temperature measuring device to solve the problems of low detection accuracy and technical issues in the detection process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wellbore temperature measuring device, comprising a support frame installed inside the tubing, an electrical control mechanism mounted on the top of the support frame, and ventilation mechanisms mounted on both sides of the electrical control mechanism; a positioning frame mounted below the support frame on the inner wall of the tubing; two charging mechanisms connected to the top of the positioning frame, the charging mechanisms being connected to the electrical control mechanism; a hoisting mechanism also connected to the top of the positioning frame; the output end of the hoisting mechanism extending to the bottom of the positioning frame and connected to a sliding plate; temperature measuring mechanisms mounted on both sides of the sliding plate; and the temperature measuring mechanism... A power storage mechanism is installed at the top, and a charging interface is connected to the bottom of the charging mechanism. The charging interface extends to the bottom of the positioning frame, and a sealing mechanism is installed around the charging interface at the bottom of the positioning frame. A side exhaust port is opened on the side of the sealing mechanism, and a sealing slide plate is slidably connected inside the sealing mechanism. When the sealing slide plate moves into the sealing mechanism, it blocks the side exhaust port. A sealing sleeve is connected to the bottom of the sealing slide plate, and a charging port is connected to the top of the power storage mechanism. A sealing side plate matching the sealing sleeve is opened on the outside of the power storage mechanism. The sealing slide plate is movably connected to the sealing mechanism through an elastic reset mechanism.

[0007] By adopting the above technical solution, it is possible to conveniently detect the temperature at different locations inside the wellbore. During the charging process, the energy storage mechanism can be conveniently sealed with the sealing mechanism, and the gas inside the sealing mechanism can be replaced and cleaned by the ventilation mechanism, thereby reducing the dangers during the charging process.

[0008] The present invention is further configured such that a sealing frame, a surface sleeve, and an independent side gas storage chamber are provided on the outer side of the oil pipe, and a connection port extends through the independent side gas storage chamber to the inside of the oil pipe. A sealing plate is also connected between the oil pipe and the surface sleeve, and the sealing plate is symmetrically arranged with respect to the connection port of the independent side gas storage chamber.

[0009] Preferably, the gas can be additionally stored through an independent side gas storage chamber, which improves the storage effect.

[0010] The invention is further configured such that a slide rail is installed inside the oil pipe, the slide rail passes through the connection port of a set of independent side gas storage chambers, and the sliding plate matches the slide rail.

[0011] Preferably, the temperature measuring mechanism can be limited by a slide rail during the detection process to improve stability.

[0012] The present invention is further configured such that a power receiving panel is connected to the top of the electronic control mechanism, the electronic control mechanism is connected to an external power source through the power receiving panel, two sets of power receiving plates are installed on the end face of the electronic control mechanism, and power receiving wires are installed at the bottom of each power receiving plate, the power receiving wires being connected to the charging mechanism.

[0013] Preferably, the charging mechanism can be conveniently powered, and the connecting wires are sealed by a sealing sleeve.

[0014] The invention is further configured such that the air intake fan blade of the ventilation mechanism is hollow inside, a ventilation motor is connected to the side of the ventilation mechanism, the output end of the ventilation motor is located inside the ventilation mechanism and the ventilation fan blade is installed thereon, an air intake port is opened at the top of the ventilation mechanism, a ventilation sleeve is connected to the bottom of the ventilation mechanism, the ventilation sleeve extends to the top of the positioning frame and communicates with the inside of the sealing mechanism, and mounting feet are installed on both sides of the ventilation mechanism, the mounting feet supporting and limiting the ventilation mechanism.

[0015] Preferably, outside air can be easily injected into the sealing mechanism to expel the gas inside the sealing mechanism.

[0016] The invention is further configured such that a connecting plate is connected to the end face of the sliding plate away from the slide rail, and hanging plates are connected to both sides of the connecting plate. The temperature measuring mechanism is fixed on the outer wall of the hanging plate, and the energy storage mechanism is located above the hanging plate.

[0019] Preferably, this allows for convenient temperature monitoring of the wellbore and the main gas storage chamber.

[0020] The present invention is further configured such that an air intake mechanism is installed on the end face of the temperature measuring mechanism, and an air intake fan is installed inside the air intake mechanism. The air intake mechanism is connected to the interior of the temperature measuring mechanism, and the air intake fan drives the airflow from other parts into the interior of the air intake mechanism.

[0021] Preferably, it facilitates the drawing of air from other locations into the temperature measuring mechanism, making it convenient to detect the gas temperature at different locations.

[0022] In summary, the present invention has the following main beneficial effects: 1. The present invention, through the positioning frame, charging mechanism and sliding plate, can drive the temperature measuring mechanism to move up and down inside the well barrel, thereby detecting the temperature of the gas at different locations inside the well barrel. Before detection, the charging mechanism charges the energy storage mechanism so that the temperature measuring mechanism can operate normally.

[0023] 2. The present invention, through the setting of a ventilation mechanism, a charging mechanism, a storage mechanism, and a sealing mechanism, enables the storage mechanism to push the sealing slide plate inside the sealing mechanism to move upward during the charging process, thereby increasing the sealing effect between the storage mechanism and the sealing mechanism.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of the present invention will now be described.

[0029] Please see Figure 1 and Figure 2 The wellbore temperature measuring device includes a sealing frame 2, a surface casing 3, and an independent side gas storage chamber 4 on the outside of the tubing 1. The independent side gas storage chamber 4 has a connection port that extends through the independent side gas storage chamber 4 into the inside of the tubing 1. A sealing plate 8 is also connected between the tubing 1 and the surface casing 3. The sealing plate 8 is symmetrically arranged with respect to the connection port of the independent side gas storage chamber 4. A slide rail 9 is installed inside the tubing 1 and passes through the connection port of a set of independent side gas storage chambers 4.

[0030] Please see Figures 2 to 6A support frame 5 is installed inside the oil pipe 1. An electric control mechanism 6 is installed at the top of the support frame 5, and ventilation mechanisms 11 are installed on both sides of the electric control mechanism 6. A positioning frame 7 is also installed below the support frame 5 on the inner wall of the oil pipe 1. Two sets of charging mechanisms 13 are connected to the top of the positioning frame 7. The charging mechanisms 13 are connected to the electric control mechanism 6. A hoisting mechanism 14 is also connected to the top of the positioning frame 7. The output end of the hoisting mechanism 14 extends to the bottom of the positioning frame 7 and is connected to a sliding plate 16. The sliding plate 16 matches the slide rail 9, which can conveniently supply power to the charging mechanism 13 on the positioning frame 7.

[0031] Please see Figures 8 to 10 Temperature measuring mechanisms 18 are installed on both sides of the sliding plate 16. A detection head 1801 is connected to the side of the temperature measuring mechanism 18. A cavity 1803 is opened inside the temperature measuring mechanism 18. A connecting rod 1802 is connected to the side of the detection head 1801. A junction plate 1804 is installed inside the cavity 1803. The connecting rod 1802 extends into the cavity 1803 and connects to the junction plate 1804. An air intake mechanism 22 is installed on the end face of the temperature measuring mechanism 18. An air intake fan blade 2201 is installed inside the air intake mechanism 22. The air intake mechanism 22 is connected to the inside of the temperature measuring mechanism 18. The air intake fan blade 2201 drives the airflow from other parts into the interior of the air intake mechanism 22, which can draw gas from other positions into the temperature measuring mechanism 18, making it convenient to detect the temperature of gas at different positions.

[0032] Please see Figures 2 to 10 A connecting plate 17 is connected to the end face of the sliding plate 16 away from the slide rail 9. Hanging plates 21 are connected to both sides of the connecting plate 17. A temperature measuring mechanism 18 is fixed to the outer wall of the hanging plate 21. A power storage mechanism 19 is located above the hanging plate 21. A charging interface 1301 is connected to the bottom end of the charging mechanism 13. The charging interface 1301 extends to the bottom of the positioning frame 7. A sealing mechanism 20 is installed around the bottom end of the positioning frame 7 around the charging interface 1301. A side exhaust port 2001 is opened on the side of the sealing mechanism 20. A sealing slide plate 2002 is slidably connected inside the sealing mechanism 20. When the sealing slide plate 2002 moves inside the sealing mechanism 20, it blocks the side exhaust port 2001. The bottom of the sealing slide plate 2002 is connected to a sealing sleeve 2003, and the top of the sealing slide plate 2002 is connected to a spring sleeve rod 2004, a spring 2005, and an insert rod 2006, which facilitates the sliding up and down of the sealing slide plate 2002 and increases the seal between the sealing slide plate 2002 and the energy storage mechanism 19. The top of the energy storage mechanism 19 is connected to a charging port 1901, and the outer side of the energy storage mechanism 19 is provided with a sealing side plate 1902 that matches the sealing sleeve 2003. The sealing slide plate 2002 is movably connected to the sealing mechanism 20 through an elastic reset mechanism, which removes the sampling gas attached to the energy storage mechanism 19 during the charging process and improves the safety of charging.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The top of the electronic control mechanism 6 is connected to a power receiving panel 601. The electronic control mechanism 6 is connected to an external power source through the power receiving panel 601. Two sets of power receiving plates 602 are installed on the end face of the electronic control mechanism 6, and power receiving wires 603 are installed at the bottom of each power receiving plate 602. The power receiving wires 603 are connected to the charging mechanism 13.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The ventilation mechanism 11 is hollow inside. A ventilation motor 1101 is connected to the side of the ventilation mechanism 11. The output end of the ventilation motor 1101 is located inside the ventilation mechanism 11 and a ventilation fan blade 1102 is installed. An air intake port 1103 is opened at the top of the ventilation mechanism 11. A ventilation sleeve 10 is connected to the bottom of the ventilation mechanism 11. The ventilation sleeve 10 extends to the top of the positioning frame 7 and is connected to the inside of the sealing mechanism 20. A pressure control tank 15 is also installed above the positioning frame 7. A spring and a sealing plate are installed inside the pressure control tank 15, and the pressure control tank 15 is connected to the inside of the sealing mechanism 20. Mounting support feet 1104 are installed on both sides of the ventilation mechanism 11. The mounting support feet 1104 support and limit the ventilation mechanism 11.

[0035] In the process of using this invention, firstly, each set of support structures is fixed, and the sliding plate 16 of the hoisting mechanism 14 is inserted into the outside of the slide rail 9. Then, the positioning frame 7 is positioned by bolts to complete the installation of the charging mechanism 13 and the sliding plate 16 below. Then, the support frame 5 is installed, and the electrical control mechanism 6 and the ventilation mechanism 11 are installed on the support frame 5. The charging mechanism 13 is connected by the power connection wire 603. The ventilation sleeve 10 connects the ventilation mechanism 11 to the top of the positioning frame 7, and the ventilation sleeve 10 is connected to the inside of the sealing mechanism 20. During use, if it is necessary to detect the temperature inside the wellbore, the hoisting motor in the hoisting mechanism 14 is activated, driving the roller to rotate. The connecting rope on the roller is released, and the sliding plate 16 moves downward under the action of gravity. The sliding plate 16 slides downward along the slide rail 9, ensuring the stability of the sliding plate 16's movement. The sliding plate 16 drives the outer connecting plate 17 to move downward, thereby driving the temperature measuring mechanism 18 to move downward as well. At this time, the power storage mechanism 19 synchronously supplies power to the air intake mechanism 22 and the temperature measuring mechanism 18. The temperature measuring mechanism 18 detects the temperature inside the wellbore. At the same time, the air intake fan blades 2201 in the air intake mechanism 22 drive other air near the inner wall of the wellbore into the temperature measuring mechanism 18. The airflow flows along the connecting rod 1802 within the cavity 1803 and eventually reaches the position of the detection head 1801. The temperature of the flowing air is detected by the detection head 1801, thus improving the detection range. During the detection process, the temperature measuring mechanism 18 will pass through the opening of the independent side gas storage chamber 4. At this time, the downward movement of the hoisting mechanism 14 is temporarily stopped, and the air intake mechanism 22 can extract part of the gas in the independent side gas storage chamber 4, thereby enabling the detection of part of the temperature in the independent side gas storage chamber 4. After the detection is completed, the temperature measuring mechanism 18 continues to move downward until it moves into the main gas storage chamber below (not shown in the figure), thereby realizing the detection of temperature at different positions in the wellbore and in the gas storage chamber. After the test is completed, the lifting mechanism 14 drives the sliding plate 16 to move upward until the energy storage mechanism 19 contacts the sealing mechanism 20. At this time, the sealing side plate 1902 first contacts the sealing sleeve 2003, thereby sealing the sealing side plate 1902 and the sealing sleeve 2003. Then, the energy storage mechanism 19 continues to move upward, pushing the sealing slide plate 2002 upward, thereby discharging the gas in the sealing mechanism 20 through the side exhaust port 2001. At the same time, the ventilation mechanism 11 activates the ventilation fan blades 1102 to draw in outside air through the air intake port 1103, and injects other air into the sealing mechanism 20 through the ventilation sleeve 10 and discharges it through the side exhaust port 2001 until the sealing slide plate 2002 moves to the side exhaust port. When the charging port 1901 is above the sealing mechanism 2001, the ventilation mechanism 11 is activated in reverse to extract the air between the energy storage mechanism 19 and the sealing mechanism 20. This effectively removes the gas remaining in the energy storage mechanism 19 (especially the gas at the charging port 1901 and the charging interface 1301), reducing airflow contamination and preventing the electric arc generated during charging from reacting with the stored gas and causing unnecessary damage. The ventilation mechanism 11 stops operating after the charging port 1901 is inserted into the charging interface 1301. When testing is required, the ventilation mechanism 11 is activated again to inject gas into the sealing mechanism 20, preventing negative pressure from preventing the energy storage mechanism 19 from being extracted from the sealing mechanism 20 and improving the testing effect.
