Therefore, water needs to be injected into the injection well to adjust the pressure difference and facilitate normal exploitation of the oil field. During the injection process, the water needs to be filtered to avoid clogging the pipeline. Currently, the commonly used oil field injection well water injection filter device has insufficient filtration and a single filtration frequency. At the same time, the filter structure is not easy to replace, which leads to accumulation and adhesion inside the pipeline for a long time, which is easy to affect water flow. Therefore, an oil field water injection terminal filter device is proposed. Utility Model Content
