Description
Technical field
the utility model relates to oil well three phase metering device technical field, is that one has pump-type individual well three-phase metering mechanism.
Background technology
existing individual well oil-gas metering device possesses gas-liquid two-phase function of measuring usually, i.e. gas production and Liquid output, and in the manufacturing process of oil gas, and what more pay close attention to is oil production and the aquifer yield of individual well.Therefore, in order to the relevant parameter of the oil production and aquifer yield that obtain individual well, user is chemically examined by manual sampling and calculates crude oil water content, then, then estimates oil production in oil gas liquid measure and aquifer yield according to the crude oil water content calculated.Because metering and manual sampling chemically examine the time of crude oil water content not at one time in section, so, represent the moisture content moisture content of whole oil well section sometime to calculate oil output per well and aquifer yield exists larger error with certain any crude oil water content, three-phase (gas phase, aqueous phase and oil phase) measuring accuracy is not high.
when recovering the oil in the winter time, because crude oil is thicker, and tolerance is very little or higher (about the 1MPa of pressure in eliminator in metering device, but pressure is high might not be large-minded), the liquid in eliminator is caused not discharge in time, metering device is caused to carry out gage work thus, in this case, even if crude oil also usually can not be discharged by startup standby oil extraction centrifugal pump or gear pump, thus, can produce in eliminator and build the pressure phenomenon and cause safety valve jumping up pressure release, adverse influence is caused to the metering of gas production.In addition, when the pressure in eliminator is higher, the oil extraction ability of pump greatly declines and often reveals, and is also finally cause metering device often to quit work.
at present, enter between eliminator do not carry out filter operation to oil-gas-liquid at oil-gas-liquid, thus, the foreign material in oil-gas-liquid very easily cause pump (especially gear pump) stall, cause adverse influence to the metering of metering device.At present, usually adopt precession spiral flowmeter to measure gas production, because the measurement category of precession spiral flowmeter is narrower, and the gas production of individual well is comparatively large at present, adopts precession spiral flowmeter normally can not measure gas production.In addition, can not automatic water supplement at the water bag of separator bottom, thus adverse influence is caused to metering work.
