Description

Technical Field

[0001] The utility model belongs to the technical field of downhole operation of oil and gas wells, in particular to a fracturing ball heat preservation and ball passing monitoring device. Background Art

[0002] Currently, fracturing technology is often used in the development of unconventional reservoirs. Ball-dropping fracturing relies on dropping fracturing balls at the wellhead to achieve fracturing. A ball-dropper is a commonly used device in this process. To determine the success of the ball-dropping process, manual monitoring of the wellhead pipeline is often used. However, after winter, cooler weather causes condensation inside the ball-dropper, forming a thick layer of white solid frost. This frost hinders the descent of the steel balls, causing ball-dropping failures and wasting significant amounts of fluid and construction time. Furthermore, the prolonged monitoring of the high-pressure pipeline during the ball-dropping process increases the risk of high pressure. Utility Model Content

[0003] In order to solve the above deficiencies in the prior art, the present invention aims to provide a fracturing ball insulation and ball passing monitoring device to prevent the liquid in the ball pitcher from freezing at low temperatures and to monitor whether the ball pitching is successful.

[0005] As a limitation of the present invention, the heat preservation barrel is surrounded by a double layer of heat preservation cotton, and the two edges of the heat preservation cotton are bonded by adhesive buckles.

[0006] As a further limitation of the present invention, temperature sensors are installed on the upper and lower parts of the thermal insulation barrel.

[0007] As a further limitation of the present invention, the host computer is a mobile computer.

[0016] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention and are not intended to limit the present invention.

[0017] Example Fracturing ball insulation and ball passing monitoring device

[0018] like Figures 1 to 2 As shown, this embodiment includes a heat preservation barrel 6, a heating component, a temperature sensor 2, an audio sensor 4, a microcontroller 5, a relay, a controller 1, and a host computer.

[0019] The insulation barrel 6 is used to wrap the ball thrower. The insulation barrel 6 is a barrel-shaped barrel surrounded by a double layer of fireproof heat-insulating cotton. The two edges of the insulation cotton are bonded by adhesive buckles 7 (mute buckles). The ball thrower can be placed in the insulation barrel 6. The ball thrower is completely wrapped to lock the temperature and increase the insulation effect.

[0020] A heating component is built in between the double-layer thermal insulation cotton, and the heating component is an explosion-proof heating belt 8.

[0021] Two temperature sensors 2 are installed, one on the upper and one on the lower portion of the heat preservation barrel 6. The first signal output terminals of all temperature sensors 2 are connected to the signal input terminals of relays, which are designed to activate when the ambient temperature reaches a set value. When the temperature exceeds the set value, the relay disconnects the circuit, and the explosion-proof heating belt 8 stops heating. When the temperature falls below the set value, the relay connects the circuit, and the explosion-proof heating belt 8 begins heating. The relays are controlled by a controller, with the control terminals of the relays connected to the controller.

[0022] Audio sensor 4 is mounted on the fracturing pipeline to collect the sound frequencies generated by the fracturing ball passing through the pipeline. Audio sensor 4 uses an industrial-grade noise sensor that can output a 0-20 mA signal to the microcontroller 5, with a directional monitoring range of 20-130 decibels.

[0023] The signal output of the audio sensor 4 and the second signal output of all temperature sensors 2 are connected to the signal input of the microcontroller 5, which is in turn connected to the signal input of the controller 1, which is in turn connected to the signal input of the host computer. The microsensor is used to receive audio data and temperature data and transmit the received audio data and temperature data to the controller 1. After receiving the temperature data and audio data, the controller 1 transmits the temperature data and audio data to the host computer. Furthermore, the controller 1 is connected to an external power supply, which is a 220V power supply that can output a 24V low-voltage, high-power regulated power supply to meet the safe power requirements of the construction site. Specifically, the external power supply is the 220V power supply of the fracturing instrument vehicle, but the power supply method can also be flexibly selected according to the well site conditions.

[0024] The host computer is a mobile computer 3. The host computer can receive audio data and temperature data, and display the temperature curve and sound frequency curve of the fireproof insulation cotton through software, so as to judge whether the pitch is successful.

[0025] To keep a ball thrower warm using this embodiment, open the adhesive tabs 7, wrap the thrower in a double layer of insulation, and then close the adhesive tabs 7 to enhance the insulation. When the temperature sensor 2 detects that the temperature inside the insulation barrel 6 is below a set value, the relay switches on, allowing the heating belt 8 to continue heating. When the temperature sensor 2 detects that the temperature inside the insulation barrel 6 is above the set value, the relay switches off, discontinuing heating from the heating belt 8. This effectively keeps the thrower warm inside the insulation barrel 6.

[0026] When using this embodiment to monitor the success of a ball launch, an audio sensor 4 is installed on the fracturing pipeline. During the launch process, the audio frequency generated by the fracturing ball passing through the pipeline is collected. Temperature data from the temperature sensor 2 and audio data from the audio sensor 4 are transmitted to the microcontroller 5, then to the controller 1, and then to the host computer. Software in the host computer displays the temperature and audio data, allowing the operator to monitor the success of the launch and the set temperature value.

[0027] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
