Injection Interval Signal Processing Research Based on the Vortex Flow

Single-layer flow and accumulated flow monitoring of Injection-production engineering technology is a necessary means to ensure precise injection and effective water. This paper uses the vortex principle to achieve flow measurement interval. However, underground injection wells in the environment, its sensor by water injection piping vibration and noise caused the flow field disturbance double interference. For this project, this paper presents a set of dual-pass filter from wavelet algorithms to improve the system for the detection and identification capability of the sensor output signal. Numerical analysis and experimental results show that the proposed algorithm can improve the anti jamming capability of the system. The traffic monitoring is more stable and reduces the accumulated error effectively.
