Filtering device for petroleum exploitation transportation pipeline

Abstract

The invention relates to the technical field of oil exploitation, in particular to a filtering device for an oil exploitation transportation pipeline, the filtering device comprises a feeding pipe, a discharging pipe and a filtering assembly, the discharging pipe is provided with a first cavity and a second cavity, and the filtering assembly comprises a first filtering plate, a second filtering plate, a first movable plate, a first spring and a second movable plate; a long-strip-shaped sliding groove matched with the first movable plate is formed in the discharging pipe, and a first fixing hole matched with the second filtering plate to work is formed in the discharging pipe. The invention provides a filtering device for an oil exploitation transportation pipeline. Through a first cavity, a second cavity, a first fixing hole, a first filter plate, a second filter plate, a first movable plate, a first spring and a second movable plate, filtered silt cannot be excessively accumulated on the filter plates, and meanwhile, a worker can conveniently clean the silt in a discharging pipe.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a filtering device for petroleum exploitation and transportation pipelines. Background technique [0002] Petroleum is a fluid mineral buried deep in the ground. At first, 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, they are now collectively referred to as for oil. Oil extraction refers to the act of excavating and extracting oil in places where oil is stored. In the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well, and then rise from the bottom of the well to the wellhead. [0003] Since the oil resources are under the surface, the sand mixed in the oil needs to be filtered during the oil extraction work. The traditional filtering device needs to be shut down for a period of time to cl...

AI Technical Summary

Problems solved by technology

[0003] Since the oil resources are located under the surface, it is necessary to filter the mixed sediment in the oil during oil exploitation. The traditional filter device needs to be shut down to clean the sand and gravel after a period of filtering work. In this process, it is necessary to It will take a certain amount of time for the staff to disassemble, clean and install the filter device, which will affect the overall mining efficiency
