Description

Technical Field

[0001] The utility model relates to the technical field of intelligent distributed gas injection for gas wells, in particular to an intelligent distributed gas injection system for gas wells. Background Art

[0002] Gas lift technology is a key technology in oil and gas production. The principle of gas lift involves injecting natural gas or nitrogen, pressurized by a compressor, into a gas or oil well, removing the oil or water from below. To improve gas lift efficiency, a single compressor can simultaneously lift multiple wells in a platform well (or well group), achieving multiple lifts per unit. This requires the use of a distributed gas injection device.

[0003] Based on the above, the inventors found the following problems: since each well has different conditions, the required gas injection pressure and injection volume are different, and the current distributed gas injection device is not convenient for controlling the gas injection pressure and injection volume, thereby reducing the practicality of the distributed gas injection device.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and an intelligent distributed gas injection system for gas wells is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose of the present utility model is to provide an intelligent distributed gas injection system for a gas well, so as to solve the problems raised in the above background technology.

[0006] In view of the above problems, the technical solution proposed by the present invention is:

[0008] Furthermore, signal transmission connections are established between the monitoring module, data transmission module, early warning module, alarm module, communication module and control module.

[0009] The beneficial effect of adopting the above-mentioned further scheme is that by setting up a monitoring module, the gas injection volume and injection pressure of the first gas well, the second gas well and the third gas well are monitored, and then the monitored gas injection volume and injection pressure data are transmitted to the early warning module through the data transmission module. When the monitored gas injection volume and injection pressure data reach the originally set early warning value, an early warning is issued to the user's mobile phone through the communication module. By setting up an alarm module, when the monitored gas injection volume and injection pressure data reach the originally set maximum threshold value, an alarm is sent to the user's mobile phone through the communication module, so that the user can use the mobile phone to control the operation of the subdivision regulating valve through the control module.

[0010] Furthermore, the monitoring module includes a data acquisition module and a data processing and analysis module, and the input and output ends of the monitoring module are communicatively connected with the input and output ends of the flow meter and the pressure transmitter.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that, through the flow meter and pressure transmitter, the monitoring module monitors the gas injection volume and injection pressure of the first gas well, the second gas well and the third gas well. Through the coordinated use of the monitoring module, the data acquisition module and the data processing and analysis module, the data acquisition module collects the gas injection volume and injection pressure data, which are then processed by the data processing and analysis module. The data processing and analysis module is a microprocessor to facilitate the subsequent transmission of gas injection volume and injection pressure data, and the communication module directly displays it on the user's mobile phone, so that the user can read the gas injection volume and injection pressure data more intuitively.

[0012] Furthermore, the communication module includes a WIFI module, and the communication module is connected to the user's mobile phone through wireless communication via the WIFI module.

[0013] The beneficial effect of adopting the above further solution is that by providing a communication module, and the communication module including a WIFI module, it is convenient to connect to the wireless network of the user's mobile phone.

[0014] Furthermore, the control module includes a control panel, and the input and output ends of the control module are communicatively connected with the input and output ends of the subdivision regulating valve via the control panel.

[0015] The beneficial effect of adopting the above further scheme is that by setting up a control module, and the control module includes a control panel, it is convenient to pre-set the gas injection volume and gas injection pressure data, and the warning value and alarm value of the gas injection volume and gas injection pressure data can also be pre-set.

[0016] Furthermore, the subdivision regulating valve is installed on the outside of the pipeline, the pressure transmitter is installed on the outside of the pipeline on one side of the subdivision regulating valve, the flow meter is installed on the outside of the pipeline on one side of the pressure transmitter, and the one-way valve is installed on the outside of the pipeline on one side of the flow meter. The subdivision regulating valve, pressure transmitter, flow meter and one-way valve are distributed in sequence from left to right.

[0017] The beneficial effect of adopting the above further scheme is that by installing a subdivision regulating valve, the subdivision regulating valve controls the flow of gas by changing the opening of the valve to keep it within the set range, thereby ensuring stable operation. By installing a pressure transmitter, it is convenient to measure the gas injection pressure in the pipeline. By installing a flow meter, it is convenient to measure the gas injection volume in the pipeline. By installing a one-way valve, the gas is prevented from flowing backward in the pipeline.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the gas well uses an intelligent distributed gas injection system, which is used in conjunction with the well group, the regulating circuit, the compressor and the main pipeline. When the compressor is working, the gas pressure is increased, and the liquid in the first gas well, the second gas well and the third gas well is increased through the main pipeline and the three regulating circuits, thereby facilitating oil and gas production. By installing a subdivision regulating valve, the subdivision regulating valve controls the flow of gas by changing the opening of the valve, so that it is kept within the set range, thereby ensuring stable operation. By installing a pressure transmitter, it is convenient to measure the gas injection pressure in the pipeline. By installing a flow meter, it is convenient to measure the gas injection volume in the pipeline. By installing a one-way valve, the gas is prevented from flowing backward in the pipeline. By setting a control module, and the control module including a control panel, it is convenient to pre-set the gas injection volume and gas injection pressure data. At the same time, the early warning value and alarm value of the gas injection volume and gas injection pressure data can also be pre-set. The pressure transmitter enables the monitoring module to monitor the gas injection volume and injection pressure of the first gas well, the second gas well and the third gas well. The data acquisition module collects the gas injection volume and injection pressure data, which are then processed by the data processing and analysis module. The data processing and analysis module is a microprocessor, and then transmits the monitored gas injection volume and injection pressure data to the early warning module through the data transmission module. When the monitored gas injection volume and injection pressure data reach the originally set early warning value, the communication module directly displays them on the user's mobile phone, allowing the user to read the gas injection volume and injection pressure data more intuitively. At the same time, the communication module issues an early warning to the user's mobile phone. By setting the alarm module, when the monitored gas injection volume and injection pressure data reach the originally set maximum threshold, the communication module sends an alarm to the user's mobile phone, allowing the user to use the mobile phone to control the subdivision regulating valve through the control module, which can accurately control the gas injection volume and injection pressure of each well, and can also intelligently adjust the gas injection volume of multiple channels.
