Embodiment Construction

[0012] 1. The process part is researched and designed according to the technical requirements of natural gas development and production process, and the scientificity and applicability of the technical plan are verified through on-site installation and test. Natural gas is transported downstream from production wells through primary, secondary, and tertiary throttle valves, primary and secondary heating coils of heating furnaces, and orifice flowmeters according to the process flow. Natural gas pressure is roughly from P 0 ,P 1 ,P 2 ,P 3 Decrease step by step to reach the required output pressure P 3 . Due to the pressure reduction and volume expansion of natural gas, the thermodynamic temperature changes from T 0 , T 1 , T 2 , T 3 It needs to be heated by a heating furnace to meet the gathering and transportation requirements.

[0013] 2. The hardware part is designed and selected in combination with the specific technical parameter requirements of the process and th...

Abstract

The invention provides a natural gas producing well production and pressure automatically adjusting intelligent control system, belonging to the field of natural gas development and production technology and automatic control technology. The system is an intelligent control system formed by a computer, a PLC, related process equipment and a measuring meter in the natural gas field development and production process. According to the system, through the method of the combination of the automation technology and the natural gas development and production technology, the intelligent control technology is applied in the production process of a natural gas well, the gas well production and wellhead pressure are automatically controlled, the natural gas production and wellhead pressure can be automatically adjusted and controlled according to a production need, and technical method and guarantee are provided for the optimization of the natural gas field development speed and the realization of a best working effect. The technology can be widely applied to the production control of different types of natural gas field producing wells at home and abroad, and the system has a targeted intelligent monitoring alarm function for a gas field production well containing high sulfate gas at the same time.

Description

1. Technical field [0001] The intelligent control system for automatic production and pressure regulation of natural gas production belongs to the field of natural gas development and production technology and industrial automation control technology. It is a system that combines automation technology with weather development and production technology. 2. Background technology [0002] The natural gas field production gathering and transportation system includes natural gas production wells, natural gas heating furnaces, natural gas gathering and transportation and other main parts. The control of natural gas production well production and wellhead pressure is the core control part of natural gas production and transportation. At present, manual operation control, remote manual control, and single flow automatic control methods are usually used in China, that is, manual or semi-automatic control methods. Natural gas flow (gas well production) and pressure have not yet reached...
