Thematic wordCrude oil of wildcat of high water content of Daqing oil field is metric and metric device segregator appearance
Wildcat of domestic oil field is metric and common adopt ten wildcat yield fluid is entered same and metric, common the wildcat of a metric device is metric means. Two-phase is used above all in metric process metric segregator yields wildcat content cent gives two-phase of fluid, gas, measure fluid with vitreous canal next, moisture content of assay of sampling of artificial mtl pithead. Oil field is entered tall hydrous period hind, wildcat is metric and main put in the following problem:
(1) wildcat produces fluid to measure common wave motion bigger, and without the rule but abide, low yield wildcat still is put in phenomenon of intermittence yield juice, intermittent time length is differ, short chronometer quantity reachs very hard actual output, use two-phase the method that metric segregator matchs glass to be in charge of quantity oil already suited hard.
(2) the big, yield difference that wave motion causes different wildcat associated gas greatly mixes wildcat yield difference wave motion is bigger also, orifice plate matchs double ripple to provide the means measuring energy of life such as difference gauge already cannot applicable.
(3) because use tall fluid to measure production and oil reservoir fracture,wait for measure, in increasing wildcat to produce juice arenaceous with foreign matter, moisture content makes appearance easy knot dirties high again, gear flowmeter, lumbar annulus flowmeter is not applicable already.
(4) because wildcat produces juice moisture content tall, many dissociate water exists, accordingly, artificial sampling random sex is very strong, take very hard accurate, cannot get true, stable, exact moisture content is worth.
To solve above problem, contented oil field is tall hydrous period the need of metric job, begin from 80 time later period, daqing oil field basically is developed and applied wildcat three-phase detached and metric device and depart of two-phase of density law wildcat are metric device, applied fluid face to restore to wait for the method that measure oil with merit plan law in great quantities at the same time.
1 wildcat three-phase is detached and metric device
Daqing oil field begins research and depart of applied wildcat three-phase from 1986 metric device, application is at present most is WSH-94 wildcat three-phase metric device, this unit is main by three-phase appearance of metric segregator, control, metric appearance and computer data collect control system 4 parts are formed.
