[0002] Oilfield refers to a specific area where crude oil is produced, and sometimes it is a general term for oil layers gathered underground in a specific region. Filter elements can separate solid particles from liquids or gases, or allow different material components to fully contact, speed up the reaction time, and protect the normal operation of equipment or the cleanliness of the air. When the fluid enters the filter element with a filter screen of a certain specification, its impurities are blocked, and the clean fluid flows out through the filter element. Crude oil needs to be filtered using a filter element after extraction.

[0003] The shortcomings of the existing technology: when the existing oil field filter element is in use, the crude oil flows into the filter element slowly, and the crude oil cannot be filtered quickly, which is not conducive to the working efficiency. In addition, its strength is low, and it is easy to be damaged when encountering a large flow of fluid, which is not conducive to the service life of the filter element. Utility Model Content
