Description

Technical Field

[0001] This utility model relates to the technical field of acid injection devices, specifically a high-efficiency acid injection device with multi-channel parallel operation. Background Technology

[0002] Acid injection refers to the simultaneous injection of acid into different locations or sections of the formation through multiple independent injection channels (such as wellbore, tubing, or microchannels). Each channel can independently control injection parameters (such as flow rate, pressure, and acid type) to achieve precise regulation.

[0003] Existing methods for injecting acid into oil wells often employ mechanical sealing, chemical particle plugging, foam diversion, and thickened acid diversion to ensure proper acid distribution across the treated section and prevent localized acid surges. However, these methods still have drawbacks: after acidizing, the injection device requires internal cleaning, which current technologies often involve complete disassembly, making cleaning cumbersome. To address this issue, we propose a multi-channel, parallel-operation, high-efficiency acid injection device. Utility Model Content
