Intelligent differential pressure alarming filter device

Abstract

The invention discloses an intelligent differential pressure alarming filter device, which comprises a filter, wherein an inlet of the filter is connected with an inlet control valve through a pipeline; an outlet of the filter is connected with an outlet control valve through a pipeline; a bypass control valve is connected between the inlet control valve and the outlet control valve; the filter is connected in parallel with a pressure monitoring instrument; the pressure monitoring instrument is electrically connected with a remote computer control center. Through setting a pressure difference alarming threshold value in the computer control center, the monitoring is implemented on a pressure difference between the front and the back of the filter in an on-line manner; the alarming is carried out on overpressure data; the status that the running of a downstream process device is influenced as the manual patrol inspection is not in-position and the filter is blocked for a long time is avoided; further, a construction process is simple; the operation is convenient; the labor intensity of a worker is drastically decreased; the degree of automation is improved; the digitized development and building requirements of an oil field are met.

Description

Technical field [0001] The invention belongs to the technical field of crude oil gathering and transportation on the surface of an oil field, and particularly relates to an intelligent differential pressure alarm filter device. Background technique [0002] The oil well produced fluid contains a large amount of silt and has an impact on the heating and separation equipment of the oil field gathering station. In order to ensure the normal operation of the separation equipment of the gathering and transportation station, the gathering and transportation station is equipped with filters before processing to filter the incoming fluid from the oil well. Due to the complexity of the incoming liquid, the filter is often blocked, resulting in no liquid in the subsequent process equipment. If the blockage is not cleaned for a long time, the downstream equipment will not work properly and affect the wellhead back pressure and production of the oil well. To avoid such accidents , Oil produ...

AI Technical Summary

Problems solved by technology

Due to the complexity of the incoming liquid, the filter is often blocked, resulting in no liquid entering the subsequent process equipment. If the blockage is not cleared for a long time, the downstream equipment will not work normally and affect the wellhead back pressure and production of the oil well. To avoid such accidents , oil production workers need to strengthen inspections and clear blockages in a timely manner, and the work intensity is high

However, in the actual production process, due to the untimely inspection and supervision of the oil production workers, the filter is blocked from time to time.
