Description

Technical Field

[0001] This utility model relates to the technical field of oil and gas field chemical dosing devices, specifically an oil and gas field chemical dosing device for preventing sedimentation. Background Technology

[0002] To ensure the normal operation of oil wells, gas wells, gas pipelines, and their fittings and instruments, functional chemical agents, which are liquid at normal temperature and pressure, are typically added to the wellbore or pipeline at oil and gas production sites to inhibit corrosion, prevent scaling, or improve fluid flow. This process is called chemical dosing. Currently, production sites generally handle two types of chemical dosing: continuous dosing and intermittent dosing. Continuous dosing involves loading the chemical agent from the tank into a chemical dosing truck, which then pumps it into a storage tank, followed by continuous online dosing using a metering pump. Intermittent dosing involves directly injecting the chemical agent from the tank into the oil and gas well or pipeline based on actual production conditions.

[0003] However, existing reagent tanks are prone to sedimentation due to prolonged standing, temperature changes, or uneven mixing. This sediment can clog pipes or pump valves, reduce dosing efficiency, or affect treatment results due to uneven reagent concentration, and may even lead to production accidents.

[0004] Based on this, a chemical dosing device for oil and gas fields that prevents precipitation is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
