A sand and gravel filter device for oil exploitation

Abstract

The invention discloses a sand and gravel filtering device for petroleum exploitation, comprising a feeding guide pipe, an output end of the feeding guide pipe is fixedly connected with an inner filter mechanism, the output end of the inner filter mechanism is fixedly connected with a discharge outlet, and the inner filter mechanism includes a filter A through slot, one end of the inner side of the filter through slot is rotatably connected with a folded filter plate, an active slot is arranged in the middle of one side of the filter through slot, and the left end of the folded filter plate is fixedly connected with an outer extension pull plate, and the outer extension pull plate passes through And extends to the outside of the movable slot, the inside of the pleated filter plate is evenly provided with filter adsorption holes, the inside of the filter through slot and located on the front of the pleated filter plate is fixedly connected with a positioning bushing, the interior of the positioning bushing penetrates and is screwed. There is a transmission tie rod, and the invention relates to the technical field of oil exploitation sand. The oil extraction sand and gravel filter device can increase the oil transmission resistance, reduce the oil flow rate, ensure the full filtration of the oil, and at the same time improve the filtration precision, and filter the fine particles together.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a sand and gravel filtering device for petroleum exploitation. Background technique [0002] Petroleum is a fluid mineral buried deep in the ground. Initially, people called oily liquid minerals produced in nature as petroleum, flammable gases as natural gas, and solid flammable minerals as asphalt. With the in-depth study of these minerals, it is recognized that they are all hydrocarbon compounds in composition and are related to each other in terms of genesis, so they are collectively referred to as petroleum. In September 1983, the 11th World Petroleum Congress proposed that petroleum is a complex mixture consisting of gaseous, liquid and solid hydrocarbon compounds and a small amount of impurities that exist in nature. Therefore, oil extraction also includes natural gas extraction. [0003] Oil extraction refers to the act of excavating and extracting oil in...
