Description

The ternary fluid is regardless of from the on-line measurement instrument

Technical field

The utility model relates to oil exploitation and oil refinery technical field, and particularly in the oil exploitation process, oil, rock gas and local water be the on-line continuous detection measurement technology device of existence condition fluid-mixing down together.

Background technology

The measuring method of ternary in the existing oil exploitation process (oil, rock gas, local water) fluid-mixing has two kinds:

1, gauging separation vessel and hand sampling assay method: adopt the huge measuring system of a cover, separate again earlier and detect.Gauging separation vessel by about 0.6 cubic metre of volume, after earlier the gas in the fluid-mixing, mixing material being separated, measure tolerance more respectively and mix liquid measure, the method by sampling and measuring or chemical examination water percentage calculates the oil mass and the water yield in the mixing material at last.The complex structure of this measuring system, complex operation, accuracy of measurement lower (± 20 ∽ 35% approximately), the error amount that human factor causes is bigger, and application is relatively limited to (being only applicable to the level Four test satellite location).

2, triphase separator and each individual event instrument (gas meter, oil meter, water meter) measurement Law: build the huge measuring system of a cover, adopt to separate again earlier and detect, or detect liquid phase component and gas phase component respectively with the r ray.This systems engineering cost height (being generally 80～2,400,000 yuan), and application is relatively limited to (terminal or the central treatment station that generally only are applicable to fluid-mixing), its accuracy of measurement is respectively: crude oil ± 10%, sewage ± 10%, rock gas ± 20% (be only applicable to CONDITIONS IN INELASTIC ELECTRON, can't reach generally speaking at all).And in the oil exploitation process, the starting end of the fluid-mixing of production wellhead under surface condition can not be suitable for this system at all.

The utility model content

The utility model purpose be Development and design a kind of simple in structure, easy and simple to handle, economical and practical, fluid-mixing does not separate, the measuring instrument of direct-on-line continuous detecting for ternary (oil, rock gas, local water) that accuracy of measurement is high.

Fluid dispenser of the present utility model is provided with housing and cuts apart device, at the upper/lower terminal of housing be tightly connected respectively upper cover plate and lower cover, in housing, be provided with and cut apart device, be provided with the motive seal chamber described cutting apart between device and housing, upper cover plate, the lower cover, connects pipe on described motive seal chamber; Left and right two ends at housing connect feed line and flow line respectively, in the upper end in motive seal chamber pressure transducer and temperature sensor are set respectively, and differential pressure transmitter and liquid level sensor were set in described communicating pipe; The signal output part of described temperature sensor, pressure transducer, differential pressure transmitter and liquid level sensor is connected the signal input part of data collection processor; The output terminal of described data collection processor is provided with oil mass signal output terminal, water yield signal output part, tolerance signal output part, temperature signal output terminal, pressure signal output terminal and differential pressure signal output terminal respectively.

The ternary fluid-mixing enters from the feed line of housing one end, discharges from the flow line of the housing other end then, does not influence normal flow velocity.When fluid enters when cutting apart the motive seal chamber (that is: measuring unit) that device and housing, upper cover plate, lower cover form, under the effect of gravity, rock gas, oil, local water produce the natural separation of gas, liquid because of different specific weight.Calculate instantaneous tolerance value by Level Detection method meter, the gravimetric value of the instantaneous mixing material that records according to differential pressure transmitter calculates the instantaneous density value of this mixed liquor again, calculates the content and the value thereof of two media in the mixing material (local water, oil) at last according to the difference sum formula.Just can obtain oil, rock gas, these three kinds of fluid-mixings of local water total amount value separately after adding up respectively.The utility model structure is simpler, and unmanned is error, the accuracy of measurement height, and application is comparatively extensive, has realized the continuous detecting of the direct-on-line of fluid-mixing.

In order to form motive seal chamber simple in structure, the described device of cutting apart of the present utility model comprises the axis that is arranged on one heart in the housing, the two ends of described axis connect cylindrical shell by bearing respectively, described cylindrical shell and described housing arranged concentric, sidewall at cylindrical shell is symmetrical arranged four vertical open slots, at fixedly connected two the identical eccentric wheels of the middle part of axis difference, described two eccentric wheels interlace 90 °, outside each eccentric wheel, be nested with a abutment ring respectively with mounting hole, abutment ring than major diameter to the fixedly connected respectively plate of cutting apart in two outer ends, described respectively cutting apart in the open slot that the sheet separation formula is plugged on corresponding described cylinder lateral wall.

Owing to be provided with eccentric wheel on the axis, by eccentric wheel control linkage ring and in relative rotation cylindrical shell do radially to-and-fro movement, making two of same abutment ring cut apart plate does to stretch out or retraction movement on an open slot radially of cylindrical shell, when one on the same abutment ring cut apart plate and stretches out in the open slot of cylindrical shell fully, another cut apart then withdrawal fully of plate.Because two eccentric wheels interlace 90 °, then make two two couples on the abutment ring cut apart plate and also are mutually 90 °.When fluid when housing enters, under the promotion of fluid, the plate of cutting apart that stretches out promotes eccentric wheel, drives abutment ring and cylindrical shell and rotates, and the motive seal chamber is formed in different cutting apart between the plate, makes also that fluid is smooth and easy to be passed through.When cutting apart plate and all stretch out in cylindrical shell for each one on two abutment rings, then cut apart plate, two and cut apart the motive seal chamber that the relative cylinder lateral wall of plate and housing sidewall, upper cover plate, lower cover have formed rotary type by these two.

Print for convenience, the output terminal of described data collection processor also is provided with printing interface.

The output terminal of described data collection processor also is provided with 482 output ports, the wired or wireless transmission mode of The data.
