Description
Technical field
The utility model relates to oil gas field field, particularly a kind of movable well mouth gauging calibration device.
Background technology
According to oil field gathering and transportation technological process present situation, crude oil measurement system is divided into 4 grades of meterings: externally crude transition metering-oil producing operation district clean oil handing-over metering-wellblock crude oil measurement-well website crude oil measurement.The pipeline flow-direction measuring station that the crude oil that every a bite producing well is extracted out is laid along ground; The crude oil of each well output is carried out measuring rear convergence and is transported to metering block station by measuring station; Metering block station utilizes oil transfer pump by Crude Oil Transportation to large-scale centralized treating stations by after the next oily convergence of each measuring station; The crude oil that extraction is split by central treating station carries out dewatering, stablize, desanding, reach after paraffin removal, flows to oil transportation company.
Along with the oil field development time constantly extends, aging by measuring equipment, pipeline corrosion, production decline, the many factors impacts such as product shaft building, adjust well constantly increase, oil well measurement contradiction, is mainly manifested in following two aspects: one is that metrical instrument administration oil well is too many, the oil well measurement cycle is long, and Dose times does not reach requirement; Two is measurement flow imperfections, and the reason such as low and equipment fault of well yield causes oil well singly to measure.Add that the dual-volume storage automaticity in the measuring equipment used at present is low, there is potential safety hazard in large tank metering, merit figure gauge and tipping bucket gauge also Shortcomings all to some extent, cause most of oil well can not normal one-well metering, Dose times wretched insufficiency, has a strong impact on the normal admission of basic data.
The common production fluid of tens mouthfuls of oil wells of taking of current oil field at home oil well measurement enters same metering room, shares the oil well measurement mode of a set of metering device.First fluid, gas two-phase is divided with two-phase flow measurement separator by output content from oil well in metering process, then with glass tube amount liquid, artificial wellhead sampling chemical examination moisture content.After oil field enters high water-cut stage, mainly there is following problem in oil well measurement:
The common fluctuation of oilwell produced fluid amount is comparatively large, and does not have rule to follow, and stripper well also exists production fluid intermittency, and the intermittent time is different in size, and metering is in short-term difficult to draw real output, adopts the method for two-phase flow measurement separator glazing pipe gauging to be difficult to adapt to.
The output difference that oil well output difference is large, fluctuation causes greatly different oil well associated gas and fluctuation are also comparatively large, and orifice plate is joined the survey gas methods such as dual bellows differential gauges and can not be suitable for.
Owing to adopting the measures such as the production of high liquid measure and formation fracturing, add the sand in oil well liquid-producing and impurity, moisture content height makes again the easy fouling of instrument, and gear meter, rotz flowmeter are inapplicable.
Because oil well liquid-producing moisture content is high, have a large amount of free water to exist, therefore, manual sampling randomness is very strong, is difficult to get standard, cannot obtain true, stable, water cut value accurately.
For overcoming the above problems, meet the needs of oil field high water-cut stage gage work, from the later stage eighties so far, each elephant and research institution, for the above problem various oil well metering device of development and application again, achieve certain effect respectively.Such as: multiple metering method and the device such as three Phase Separating-Metering Device, densimetry oil well two-phase precipitation device, dual-volume storage metering, power graph method metering.But the complexity of the various work condition environments due to existence, always there is various deficiency in different metering methods under embody rule condition.
