Embodiment 1

[0046] Embodiment 1: as attached figure 1 , 2 , 3, and 4, the automatic control gas well control cabinet includes a control cabinet main body 1, an operation area 2 is arranged on the inner upper part of the control cabinet main body 1, and a control panel 3 and a display module are fixedly installed in the operation area 2 , the main control module, interface module, data storage module, time cycle control module and pressure control module are fixedly installed in the control cabinet main body 1 at the bottom of the operation area 2, and the display module, control panel 3, data storage module and interface module are all connected with The main control module is electrically connected, and the main control module communicates with the time cycle control module and the pressure control module respectively.

[0047] attached here figure 1 , 2 , 3, and 4, the main control module and the interface module are existing known technologies, and the main control module can be a p...

Embodiment 2

[0056] Embodiment 2: as figure 1 , 2 , 3, 4, and 5, the automatic control method of the automatic control gas well control cabinet comprises the following steps:

[0057] In the first step, the staff inputs parameter information to the main control module through the control panel 3, and then enters the second step;

[0058] In the second step, if the input is opening time, shutting time, temporary change of opening time and temporary change of closing time, then enter the third step, if the input is Casing pressure and shut-in casing pressure, then enter the sixth step, if you input the well opening time, well shut-in time, well opening oil pressure, well closing oil pressure, opening well casing pressure and well casing pressure at the same time, then enter the ninth step;

[0059] In the third step, the main control module sends the well opening time and well closing time input by the staff to the time cycle control module, and the time cycle control module sets the time ...

Abstract

The invention relates to the technical field of oil and gas well control and provides an automatic control gas well control cabinet and an automatic control method thereof. The automatic control gas well control cabinet comprises a control cabinet main body, a control panel and a display module are fixedly installed in the operation area, and a main control module, an interface module, a data storage module, a time cycle control module and a pressure control module are fixedly installed in the control cabinet main body at the bottom of the operation area; the display module, the control panel,the data storage module and the interface module are all electrically connected with the main control module, and the main control module is in communication connection with the time cycle control module and the pressure control module. The invention solves the problems that the well switching on time and the well switching off time are long in the control process of the existing gas well controlcabinet and the control of the well switching on and off is not flexible through the main control module, the time cycle control module and the pressure control module, flexibly operates the well switching on and off according to the actual condition, reduces the cost, avoids construction and commissioning, avoids network maintenance and software maintenance, has high reliability, and achieves flexible control and safe operation.

Description

technical field [0001] The invention relates to the technical field of oil and gas well control, and relates to an automatic control gas well control cabinet and an automatic control method thereof. Background technique [0002] At present, my country's natural gas resources are not very rich, and the regional distribution of reserves is very uneven. In recent years, with the rapid development of the global economy and the enhancement of the awareness of global environmental protection, the demand for natural gas as the cleanest energy is increasing. It is becoming more and more urgent. In some low-permeability areas of our country, the exploitation of natural gas is also in full swing. Due to the irregular changes in the well conditions of gas wells, and the simple time cycle control mode and pressure control mode adopted by the gas well control cabinet at present, there are problems such as long opening time and well closing time, inflexible control, and the gas well is rel...
