Description

Technical Field

[0001] This utility model relates to the field of oil and gas field development equipment technology, and more specifically, to an intelligent gas wellhead device that enhances drainage function. Background Technology

[0002] During natural gas extraction, large amounts of formation water or condensate are often generated within the wellbore. If the liquid cannot be drained in time, it can lead to wellbore accumulation, a drop in well pressure, and in severe cases, even production shutdown. Traditional wellhead equipment often employs gravity settling or simple cyclone separation structures, which have the following technical drawbacks:

[0003] Low gas-liquid separation efficiency: Conventional hydrocyclones are ineffective at separating low-velocity, high-liquid-content gas streams, which are prone to secondary accumulation in pipelines;

[0004] Delayed drainage control: Relying on float valves or timers to control drainage, lacking real-time liquid level monitoring, often results in problems such as "untimely emptying" or "pressure fluctuations caused by excessive drainage";

[0005] Insufficient adaptability: Fixed structural parameters make it difficult to match the working conditions of rising water cut and dynamic changes in gas-liquid ratio during the middle and late stages of gas well production.

[0006] In recent years, some improvement schemes have attempted to introduce sensors and electronically controlled valves, but these have the following limitations:

[0007] The sensor only monitors a single parameter (such as liquid level) and is not linked to the wellhead pressure for control. The drainage process can easily disrupt the pressure balance of the gas well.

[0008] The control unit and the wellhead body are designed separately, which results in low reliability in high-pressure and highly corrosive environments.

[0009] Without optimizing the core structure of gas-liquid separation, the intelligent features are only applied to the drainage execution end, failing to fundamentally improve separation efficiency.

[0010] Therefore, there is an urgent need for a wellhead device that integrates gas-liquid separation and drainage control, which can achieve efficient, stable, and adaptive drainage and gas production through structural innovation and intelligent algorithm collaboration. Utility Model Content

[0011] To overcome the shortcomings mentioned above, this utility model aims to provide an intelligent gas wellhead device that enhances drainage function. By integrating a spiral flow guiding structure, a porous baffle gas-liquid buffer, and a dual-parameter intelligent control system for liquid level and pressure, it effectively solves the problems of low separation efficiency, delayed drainage, and poor adaptability to operating conditions of traditional devices.

[0012] This utility model discloses an intelligent gas wellhead device with enhanced drainage function, comprising a main body, a spiral guide section, a buffer plate, a water collection tank, and a drainage component; the spiral guide section is disposed inside the main body and is fixedly connected to the main body via a support column; the buffer plate is fixedly disposed inside the main body above the spiral guide section; the water collection tank is disposed below the main body and is connected to the main body via a water supply pipe; the drainage component is connected to the water collection tank.

[0013] Preferably, the drainage assembly includes a drainage pipe, a liquid level sensor, and an electric valve. The liquid level sensor is disposed inside the water collection tank, the drainage pipe is connected to the water collection tank, and the electric valve is disposed on the drainage pipe.

[0014] Preferably, an input pipe is provided on one side of the main device, an input valve is provided on the input pipe, and the input valve is connected to a connecting pipe.

[0015] Preferably, a pressure relief pipe is provided on the other side of the main device, and a pressure relief valve is provided on the pressure relief pipe.

[0016] Preferably, a gas transmission pipeline is provided above the main device, and a main gas transmission valve is provided on the gas transmission pipeline. The main gas transmission valve is connected to a pipeline adapter through a second gas transmission pipeline, and the pipeline adapter is connected to a gas output valve through the second gas transmission pipeline.

The pressure sensor is located inside the main device, and the controller controls the opening and closing of the electric valve according to the signals from the pressure sensor and the liquid level sensor.

[0019] Therefore, this utility model is an intelligent gas extraction wellhead device with enhanced drainage function using the above-described structure, and its beneficial effects are as follows:
