Description

Technical Field

[0001] This utility model relates to the field of foam drainage technology, and in particular to a wide-temperature-range refined intelligent foam drainage and gas collection device system. Background Technology

[0002] The foam drainage device (foam drainage gas production device) is a key piece of equipment in natural gas extraction to solve the problem of liquid accumulation in gas wells. It injects a foaming agent to foam the water at the bottom of the well, reducing the liquid density, and uses gas flow to carry the liquid to the surface, thereby increasing the gas well production.

[0003] Currently, the level of intelligent control of foaming and rinsing devices is low, and they still rely on manual operation and data recording.

[0004] To address the above issues, there is an urgent need for an intelligent soaking and drainage system that can perform the soaking and drainage process efficiently. Utility Model Content

[0005] This utility model provides an intelligent soaking and draining system that can perform soaking and draining work efficiently.

[0006] This utility model provides an intelligent foaming system, including a filling skid, a mixing tank, a stock solution tank, a water tank, and a controller;

[0007] The mixing tank is equipped with an electric stirrer. The mixing tank includes a foaming mixing tank and a defoaming mixing tank, which respectively contain foaming agent and defoaming agent. The stock solution tank includes a foaming stock solution tank and a defoaming stock solution tank. The inlet of the foaming mixing tank is connected to the foaming stock solution tank and the water tank, respectively. The inlet of the defoaming mixing tank is connected to the defoaming stock solution tank and the water tank, respectively. The water tank pumps liquid into the mixing tank through a water pump. The stock solution tank pumps stock solution into the mixing tank through a magnetic pump. The foaming mixing tank is connected to the well inlet pipeline, and the defoaming mixing tank is connected to the well outlet pipeline. The injection skid is used to drive the fluid in the mixing tank to be discharged. The electric stirrer, the water pump, the magnetic pump, and the injection skid are electrically connected to the controller.

[0008] In one possible design, the inlet pipe of the water tank is equipped with an inlet ball valve.

[0009] In one possible design, the water tank, the raw liquid tank, and the mixing tank are all equipped with level gauges.

[0010] In one possible design, the level gauge includes a local level gauge and / or a remote level gauge.

[0011] In one possible design, a metering pump is installed in the connecting pipe between the stock solution tank and the mixing tank.

[0012] In one possible design, the stock solution tank, the water tank, and the mixing tank are all equipped with liquid level sensors.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] In this embodiment, the controller is electrically connected to the electric stirrers on the two mixing tanks, the inlet water pumps on the two mixing tanks and the water tank, the magnetic pump between the raw material tank and the mixing tank, and the injection skid, thereby realizing intelligent operation of the entire foaming and defoaming process. Specifically, the controller controls the inlet water pump of the mixing tank to pump water into the mixing tank, and the magnetic pump between the raw material tank and the mixing tank to precisely pump the raw material into the mixing tank. The raw materials are foaming agent and defoaming agent, respectively. It should be noted that the use of a high-precision magnetic pump combined with servo electric drive technology can further improve the accuracy of the reagent preparation, achieving ±0.1‰ reagent preparation. The electric stirrers on the top of the two mixing tanks mix the reagent and water evenly under the action of the controller. After the liquid in the two mixing tanks is evenly mixed, the controller controls the injection skid to provide high pressure, pumping the solution out of the mixing tank.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] In this specification, it should be understood that the directional terms such as "upper" and "lower" used in the description of the embodiments of this utility model are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this utility model.

[0026] like Figure 1 As shown, this utility model embodiment provides an intelligent foaming system, characterized in that it includes a filling skid 1, a stirring tank, a stock solution tank, a water tank 6, and a controller 7;

[0027] The mixing tank is equipped with an electric agitator and includes a foaming mixing tank 2 and a defoaming mixing tank 3. The foaming mixing tank 2 and the defoaming mixing tank 3 are respectively filled with foaming agent diluted in a certain proportion and defoaming agent diluted in a certain proportion. The stock solution tank includes a foaming stock solution tank 4 and a defoaming stock solution tank 5. The liquid inlet of the foaming mixing tank 2 is connected to the foaming stock solution tank 4 and the water tank 6 respectively. The liquid inlet of the defoaming mixing tank 3 is connected to the defoaming stock solution tank 5 and the water tank 6 respectively. The water tank 6 pumps liquid water into the mixing tank through a water pump. The stock solution tank pumps stock solution into the mixing tank through a magnetic pump. The foaming mixing tank 2 is connected to the well inlet pipeline, and the defoaming mixing tank 3 is connected to the well outlet pipeline. The injection skid 1 is used to drive the fluid in the mixing tank to be discharged. The electric agitator, water pump, magnetic pump and injection skid 1 are electrically connected to the controller 7.

[0028] In this embodiment, the controller 7 is electrically connected to the electric stirrers on the two mixing tanks, the inlet water pumps on the two mixing tanks and the water tank, the magnetic pump between the stock solution tank and the mixing tanks, and the filling skid 1, thereby realizing intelligent operation of the entire foaming and draining process. Specifically, the controller 7 precisely pumps water and stock solution into the two mixing tanks through the inlet water pumps of the two mixing tanks and the magnetic pumps between the two stock solution tanks and the mixing tanks. The stock solution consists of a foaming agent and an antifoaming agent, respectively. After the water level in the water tank drops, the water in the water tank is automatically replenished by the water tank purification pump or municipal water. It should be noted that the use of a high-precision magnetic pump combined with servo electric drive technology can further improve the accuracy of the reagent preparation, achieving a reagent preparation accuracy of ±0.1‰. Under the action of the controller 7, the electric stirrers on the top of the two mixing tanks mix the reagent and water evenly. After the liquids in the two mixing tanks are mixed evenly, the controller 7 controls the injection skid 1 to provide high pressure, pumping the solution out of the mixing tank. The agent in the foaming raw material tank 4 is pumped into the well inlet pipeline through the high pressure provided by the injection skid 1 to foam, and the agent in the defoaming raw material tank 5 is pumped into the well outlet pipeline through the high pressure provided by the injection skid 1 to defoam, thus realizing intelligent foam drainage.

[0029] From the preparation of raw materials such as foaming agents and water to precise delivery and real-time monitoring, the entire process is automated by an intelligent system. Eliminating subjective biases from manual operation, it strictly follows preset procedures, ensuring precise proportioning and dispensing at millimeter and milliliter levels, achieving zero error and laying a solid foundation for efficient shale gas extraction.

[0030] The equipment adopts a modular architecture, with functional units such as water tank 6, raw material tank, mixing tank, transfer pump set, filling skid 1, and controller 7 operating independently and collaboratively. During maintenance, problematic modules can be quickly located and repaired individually, reducing downtime and maintenance costs. To meet process upgrades, new modules can be flexibly added, such as control programs, sensors, and filling units, adapting to industry development and extending the investment value of the equipment.

[0031] Furthermore, in addition to using high-precision magnetic pumps and servo electric drive technology to achieve ±0.1‰ reagent preparation, FOC control algorithm technology, permanent magnet synchronous motor technology, automatic stroke control technology, and plunger-type metering pump can be used to achieve a reagent dispensing function with an accuracy of 0.5‰ for both initiating and defoaming agents.

[0032] In some embodiments of this utility model, the inlet pipe of the water tank 6 is equipped with an inlet ball valve.

[0033] In this embodiment, the inlet ball valve can be electrically connected to the controller 7, and the controller 7 controls the opening and closing of the ball valve.

[0034] In some embodiments of this utility model, the water tank 6, the original liquid tank, and the stirring tank are all equipped with level gauges.

[0035] In some embodiments of this utility model, the level gauge includes a local level gauge and / or a remote level gauge.

[0036] In this embodiment, the remote level gauge can directly transmit the level data to the controller 7, which then automatically adjusts the inlet pump to regulate the level as needed. Alternatively, a standard local level gauge can be installed for convenient monitoring of the level by staff.

[0037] In some embodiments of this utility model, a metering pump is provided in the connecting pipe between the stock solution tank and the mixing tank.

[0038] In this embodiment, the metering pump can precisely adjust the flow rate.

[0039] In some embodiments of this utility model, the stock solution tank, water tank 6, and stirring tank are all equipped with liquid level sensors.

[0040] In this embodiment, the liquid level sensor can be integrated with multiple monitoring devices to provide real-time feedback on data such as flow rate and concentration. The system automatically analyzes and dynamically adjusts, such as adjusting pump speed, adjusting pump rotation time to optimize dosing, and correcting raw material ratios. This "monitoring-feedback-adjustment" closed-loop mechanism allows the equipment to function like a "smart brain," constantly adapting to changes in operating conditions, ensuring that the bubble removal operation is always in optimal condition, improving airlift efficiency, and reducing energy waste.

[0041] In some embodiments of this invention, the pressure after adding the skid pump is 10 MPa.

[0042] In some embodiments of this utility model, the filling skid 1 has a processing capacity of 42L / h.

[0043] In some embodiments of this utility model, the intelligent bubble drainage system is installed in a container, and the outside of the container is wrapped with an insulation layer and / or a heating layer.

[0044] In some embodiments of this invention, the heating layer comprises a carbon nanotube heating material.

[0045] Employing novel carbon nanotube heating materials, a rational layout, and insulation design, the system efficiently and cost-effectively ensures continuous operation in an environment of -40℃. It is mainly used for the refined and intelligent drainage of unconventional natural gas wells such as shale gas, tight gas, and coal gas in high-altitude and cold regions, realizing continuous all-weather drainage operations for unconventional natural gas wells in high-altitude and cold regions.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
