Oil extraction filter

Abstract

The invention discloses an oil extraction filter. The oil extraction filter comprises a filtering tank, a casing, a cross beam, a shaft control box and a cleaner, wherein the shaft control box is arranged above the casing; a main motor is arranged above the shaft control box; a main rotating shaft is arranged below the main motor; an oil inlet pipe is arranged at the left side of the shaft control box; an adding pipe is arranged below the oil inlet pipe; a controller is arranged at the right side of the shaft control box; a speed reducer is arranged inside the shaft control box; a secondary rotating shaft is arranged below the speed reducer; the filtering tank is arranged inside the casing; a grit collector is arranged below the filtering tank; number gauges are arranged on the surface of the shaft control box; indicating lamps are arranged below the number gauges; a discharge adjusting rod is arranged on the surface of the cleaner. According to the oil extraction filter disclosed by the invention, an arranged main sieve plate is of a telescopic vibration structure, an effect of performing vibration filtering on crude oil before production can be realized, and an effect of optimizing a filtering effect of an oil product is realized under the condition that a filtering plate is enabled not to be blocked.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an oil recovery filter. Background technique [0002] In the ground production wells of oil fields, the well fluid flowing out from the formation contains a certain amount of sand particles. When the content of sand particles is high, it will affect the production of oil wells, causing sand buried oil production devices or sand grains to wear oil production devices, causing oil wells to fail to produce or shorten The production cycle will cause significant economic losses. At present, as many oil wells are in normal production for more than half a year, a large amount of sand will be produced, and as the water content of oilfield wells rises, the sand production in the production layer will be serious, and the sand control screens used in general oil wells , can not effectively prevent part of the sand from entering the pump barrel and being pumped to the ground, resulting in a l...
