The oil well dump metering is the control separation vessel automatically
Technical field
The utility model relates to a kind of electrical apparatus control equipment, relates in particular to a kind of oil well dump metering control separation vessel automatically.
Background technology
At present, the dynamic production data of oil well is an important evidence of carrying out numerical reservoir simulation, performance analysis and instructing step stable yields under the oil field, and oil well measurement is an important step of oil well production data recording.The watch-dog of known oil well output, the form of normally disperseing to form after single setting or the simple combination switch board.For example, China Patent No. " 200920203074.X " discloses a kind of Weighing type crude production rate self-measuring device, its applying date is on September 2nd, 2009, Granted publication day is on May 19th, 2010, it comprises outer tank body and Control System of Microcomputer, tank body is provided with former oil-in and gas outlet outside, be provided with weighing jar and LOAD CELLS outside in the tank body, its special character is: described weighing jar is suspended in the outer tank body, former oil-in extends in the weighing jar, described LOAD CELLS is located on the hanger bar of weighing jar, and LOAD CELLS is connected with Control System of Microcomputer, is provided with the separation umbrella below the corresponding former oil-in in the weighing jar.
But also there is following deficiency in existing oil well measurement: one, function imperfection, put nonstandardization, inconvenient operation, monitoring parameter is inaccurate, show and concentrate, data can not Network Transmission etc. drawback, utilize two kinds of quantitative models of dual volume separator and pressurizing tank all to have certain limitation.Two, dual volume separator is big to high oil-gas ratio oil well measurement error, and pressurizing tank quantitative model system is not airtight, and potential safety hazard is big, the associated gas serious waste of resources.Three, big jar of manual gaging's metering, labour intensity is big, and is dangerous, and error in dipping is big.Four, mass rate instrument metering, the metering of turbine flow instrument, the price height, error is bigger, and can't measure use winter.Five, power graph method metering, investment is big, and is inaccurate, unreliable, and automatic management is too complicated.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above that existing oil well metering device exists, a kind of oil well dump metering control separation vessel automatically is provided, the utility model carries out the gravimetric method metering to oil well output, crude oil after the metering is transported to the downstream website by the device air pressure inside from compressing into into mixing line, guaranteed that total system is airtight, effectively prevent potential safety hazard, and accurate measurement, simplify the surface gathering and transferring technological process greatly, be adapted to the outlying well of low permeability oil field, Pressure Curve in Oil Testing Well, the pipeline that enters the station is long, the low yield that back pressure is high, the automatic control of low pressure well individual well production fluid amount.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of oil well dump metering is the control separation vessel automatically, comprise the separation umbrella, it is characterized in that: described separation pack is drawn together separation chamber and measuring room, the separation chamber is provided with crude oil import and exhaust line, be provided with the gas-oil separation snubber assembly in the separation chamber, be provided with Skip meter in the measuring room, separation chamber and measuring room are provided with leakage fluid dram.
Be provided with temperature sensor on described separation chamber and the measuring room.
Described measuring room is provided with liquid level sensor and following liquid level sensor.
Adopt advantage of the present utility model to be:
One, the utility model carries out the gravimetric method metering to oil well output, crude oil after the metering is transported to the downstream website by the device air pressure inside from compressing into into mixing line, guaranteed that total system is airtight, effectively prevent potential safety hazard, and accurate measurement, simplify the surface gathering and transferring technological process greatly, be adapted to the outlying well of low permeability oil field, Pressure Curve in Oil Testing Well, the low yield that the pipeline that enters the station is long, back pressure is high, the automatic control of low pressure well individual well production fluid amount.
Two, the utility model is reasonable in design, working stability is reliable, accurate measurement, installation and maintenance convenient, continuous measurement and interruption metering all can, and not limited by flow and cutout.
Three, the utility model effect is good, for the oil field obtains individual well production fluid data accurately, has further improved petroleum metering management work level.
Four, in the utility model,, disposable sleeve pipe gas can be discharged from exhaust line, save operation because the separation chamber is provided with exhaust line.
Five, in the utility model, on separation chamber and measuring room, be provided with temperature sensor, be convenient to control the temperature in separation chamber and the measuring room, thereby realize accurately separating.
Six, in the utility model, measuring room is provided with liquid level sensor and following liquid level sensor, is convenient to control the temperature in the measuring room, further guarantees the accuracy of metering.
