Thin oil ground gathering system

Abstract

The invention provides a thin oil ground gathering system which comprises a plurality of oil gathering branches and a treatment station; at least one oil gathering branch communicates with a plurality of thin oil wells; a metering separator is arranged at a well mouth of each thin oil well; and the treatment station communicates with the oil gathering branches through an oil gathering main. The metering separators are arranged at the well mouths of the thin oil wells, so that continuous metering of an oil-gas yield of the single well can be realized, the traditional metering transfer station is cancelled, an intermittent oil metering mode of the existing metering transfer station is changed, and production states of the thin oil wells are reflected really. In addition, the oil gathering branches communicate with the thin oil wells, so that the self-energy of the thin oil wells is used fully, the conveying radius is raised to the greatest extent, the number of station distribution stages is reduced, an oil gathering pipe network is optimized, energy conservation and consumption reduction are realized, and the ground investment is reduced.

Description

technical field [0001] The invention relates to the field of oil and gas gathering and transportation, in particular to a thin oil ground gathering and transportation system. Background technique [0002] The traditional oil and gas surface gathering and transportation process, such as the thin oil surface gathering and transportation process, usually adopts a two- or three-stage process flow of single well→metering transfer station→processing station, thus forming such as figure 1 or figure 2 The dendritic or ring-shaped gathering pipeline network pattern shown. figure 1 and figure 2 Among them, 1' is the thin oil well, 2' is the single well pipeline, 3' is the metering transfer station, 4' is the oil gathering branch line, 5' is the oil gathering main line, and 6' is the processing station. Such a gathering and transportation pipeline network model has defects such as reverse flow direction of some single wells, long gathering and transportation distance, high pressur...
