Description
Technical field
The present invention relates to a kind of device of on-line real time monitoring oil well output.
Background technology
The dynamic Liquid output of oil pumper individual well is the important foundation data in field production management, reservoir performance analysis, well group performance analysis, significant, general employing eliminator manual gaging in conventional method, yield poor results, workload is large, does not therefore reach the requirement of production, the polished rod diagram strapping of nearest domestic employing, because the installation and maintenance of polished rod load sensor are loaded down with trivial details, middle reliability is used to be difficult to ensure.Power graph method gauging is large by hole condition influence factor, and Problems is more, is only applicable to performance analysis, and the confidence space of liquid measure data is only about 50%, cannot meet Production requirement.Oil field measure on team work in popularization, mainly adopts mass flowmenter, after being arranged on block station or multi-purpose station eliminator, is applicable to the occasion that medium is comparatively simple, cannot realize the monitoring of the outer complex dielectrics fluid flow such as defeated of individual well and measuring station.Individual well production status is evaluated urgent to individual well real yield data demand.But, oil well liquid-producing exist multiphase medium, range ability change greatly, gas liquid ratio 0-100% is indefinite, containing the complicated feature such as husky, corrosivity is strong, the requirement of flow meter amount equipment and instrument is high, there is technical bottleneck for one-well metering both at home and abroad at present.
Summary of the invention
The present invention, in order to solve above-mentioned prior art Problems existing, provides a kind of oil well output monitoring device.
The technical solution adopted in the present invention is: oil well output monitoring device, comprise box body and vibration displacement sensor that one has air chamber, the bottom of described box body arranges an import, and arranges an outlet in the side of described box body, wherein, the height of described import is higher than the height of described outlet; Described vibration displacement sensor is included in the float that the air chamber being positioned at described box body arranges a vibrating arm be connected with box body top and is connected with vibrating arm lower end.
Alternatively, described float is coniform.
Alternatively, described checkout gear also comprises and is arranged on temperature pick up in air chamber and pressure sensor.
Alternatively, described box body is rectangle.
The structural principle feature of the comprehensive vortex-shedding meter of the present invention, spinner flowmeter and target type meter, suspension minor multi-parameter flow monitoring instrument has been invented in design.This instrument can realize the measuring multiple parameters of pressure, temperature, flow, auto modification viscosity and gas influence coefficient.
Float-type flowmeter of the present invention obtains the data on flows of gas-liquid two-phase fluid by the displacement and Vibration Condition of measuring float, carries out multiphase flow rates collection, due to float steady quality, add online temperature and pressure correction, so reliable measuring data, reproducible, strong adaptability.
Accompanying drawing explanation
Fig. 1 is float-type multi-parameter flow monitoring device schematic diagram.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing but not full content.
With reference to figure 1, for float-type multi-parameter flow monitoring device schematic diagram, specifically comprise box body and vibration displacement sensor 1 that one has air chamber 5, the bottom of described box body arranges an import 8, and one outlet 7 is set in the side of described box body, wherein, the height of described import 8 is higher than the height of described outlet 7; Described vibration displacement sensor 1 is included in the float 6 that the air chamber being positioned at described box body arranges a vibrating arm 2 be connected with box body top and is connected with vibrating arm lower end, also comprises and is arranged on temperature pick up 3 in air chamber and pressure sensor 4.
Particularly, by the fluid of import 8 vertical upflow, run into float 6 and produce flow resistance, this resistance converts the power promoting float 6 and move upward to, because float 6 is cones, along with float moves upward, the actual internal area of fluid becomes large, flow resistance reduces, when fluid upwards equals the weight of float to the thrust of float, float will remain on a metastable position, simultaneously, its frequency of vortex that different medium fluid produces when being subject to hindering is also different, it makes float produce vibration, vertical displacement and the vibration signal of float is measured by sensor 1, just can reflect the multimedium changes in flow rate of fluid.The design attitude of float is arranged in the air chamber 5 above fluid, little by medium impurity effect; Actual internal area is large, should not block; The steady quality of float, measurement reproducibility is good; The accuracy of detection of displacement and vibration signal is high, is beneficial to large discharge range and detects; Use for reference anti-interference, the anti-impurity performance that target type meter has, in the operating mode of the flow measurement difficulties such as low discharge, high viscosity, easily solidifying easily stifled, high/low temperature, deep-etching, strong motion, there is good compliance, in conjunction with metal floater flowmeter, there is flow area adaptivity, thus obtain large discharge scope measuring characteristic, with reference to vortex-shedding meter eddy current Formation and characteristics, isolating gas flow affects introduction.Redesign Floater Structure, make the air chamber that above float, existence one is closed, increase temperature and pressure test point simultaneously, measuring multiple parameters can be carried out to medium, pressure and temperature correction is carried out to data on flows simultaneously, make flow measurement coefficient more stable, improve flow measurement range ability and medium adaptive capacity
Wherein, liquid phase flow formula is Q
i=f (h, p, T),
Q
i: liquid phase flow, it is float amplitude h, the function of fluid pressure p and fluid temperature (F.T.) T.
Gas phase flow rate formula is Q
i=g (h, f, p, T),
Q
i: gas phase flow rate, it is float amplitude h, and float shakes frequently f, the function of fluid pressure p and fluid temperature (F.T.) T.
Adopt technique scheme, following effect can be possessed:
1. displacement and vibration parameters by measuring float 6 obtain flow signal.
2. different fluid is different to the active force reaction result of float, by detecting displacement and the vibration parameters of float, is aided with pressure and temperature parameter correction, can obtain comparatively accurate metric results.
3. the structure of uniqueness and the design of closed air chamber, makes the adaptive faculty of its test fluid flow regime extremely strong.
4. measure the mass flow of fluid, due to float steady quality, so reliable measuring data, reproducible.
5. structure is simple, and reliability is high, is easy to low cost and realizes.With good user interface, the functions such as remote access can be realized.
These are only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
