Description

Technical Field

[0001] This utility model relates to an oilfield extraction equipment, and more specifically, to a multi-well solenoid valve automatic control chemical dosing device. Background Technology

[0002] During oilfield development, various chemical agents, such as scale inhibitors, wax removers, corrosion inhibitors, and bactericides, need to be added to oil wells to prevent problems like scaling, wax buildup, corrosion, and bacterial growth. Traditional chemical dosing methods are mostly manual or use independent dosing devices for individual oil wells, which suffer from problems such as untimely dosing, high labor intensity, inaccurate dosage, and high safety hazards, making it difficult to meet the needs of modern oilfield development.

[0003] In recent years, relying on manual, timed, and quantitative chemical dosing has been inefficient, prone to errors, and unable to respond in real time to changes in well conditions. With the continuous development of automation technology, automatic chemical dosing devices have been gradually applied in oilfield development. However, most existing automatic chemical dosing devices are designed for single wells, using mechanical timers to control the dosing cycle. For well sites with multiple wells, centralized control and real-time monitoring are difficult to achieve, leading to resource waste and low production efficiency. Furthermore, existing automatic chemical dosing devices also suffer from low control accuracy and poor reliability. Therefore, there is an urgent need for a new type of device capable of automatically controlling chemical dosing across multiple wells to improve dosing accuracy and management efficiency.
