The conventional shale gas production methods usually have a complex network of control systems at the wellheads which can be controlled by several autonomous parts. This de-centralized configuration causes system instability and higher maintenance expenses. To solve these problems, one of the solutions proposed in this work is the intelligent control valve which combines sensors, regulating valves and control units into a unified system, simplifies the structure of the wellhead control system, increases the efficiency of regulation and enhances the stability of the system. Multiple control modes, including production control mode, pressure control mode, and piston gas lift mode are available in the intelligent control valve, which allows it to adapt to changing production conditions flexibly and optimize gas production rates and economic benefits at the wellhead. Results indicate that the intelligent control valve exhibits excellent stability and meets the remote control requirements of gas wells. After installing the intelligent control valve, the average daily gas production of Well A increased significantly, from 2.14×10⁴ m³/d to 2.34×10⁴ m³/d, representing a 6.86% increase compared to pre-installation levels. The average gas production efficiency improved by 5.44%, with good drainage and gas production effects. The single-well intelligent control valve system can generate an economic benefit of 355,600 yuan within six months, demonstrating high potential for promotion and application.
