Background technique

Most of China's oil fields are loose sandstone oilfields. Therefore, the difficulty often encountered in the exploitation of oil fields is that the amount of sand in the oil is large, which affects the service life of the pumping equipment, and even affects the oil content in order to remove the sand from the oil. In the middle filtration, the commonly used method is to connect the one end filter tube to the oil suction pipe in the oil layer to reduce the amount of sand mixed in the oil. At present, the commonly used sand filter tube is an inlaid sand filter tube, which is composed of a steel pipe with a plurality of inlaid holes, a metal surface filter plug and a bundle of wires, and the metal cotton filter plug is embedded in the set hole of the steel pipe, and then the wire is bundled.

Flowing down to the oil passing through the third through hole 651, the two oils are filtered and mixed together, so that the impurities therein are reduced, and then filtered through the fifth filter 63 to enter the first closed plate. On the left side of 71, the other part enters the right side of the first closing plate 71, and then the rotating filter 76 rotates around the rotating shaft 77, thereby decompressing the oil shunt entering the room, improving the stability of the device, and then passing through the After filtering, the six filters 83 and the seventh filter 86 are discharged, and some of the oil is directly discharged from the passage 82 without being filtered by the sixth filter 83 and the seventh filter 86, thereby reducing damage caused by pressure. When it is necessary to replace the device, it is only necessary to hold the bending rod 51 or the holding rod 52 to remove it. The connecting ring 87 can be used to connect to a petroleum pipeline. So far, the use process of the oil well sand filter device of the present invention has been described.

The above is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention. It is intended to be covered by the scope of the invention. Therefore, the scope of the invention should be determined by the scope of the appended claims.
