The measurement problem of certainly good formation testing well production, it is mating to need to do a large amount of equipment chainization, does so cost of investment height, also relates to
To the problem of management of related pressure container, equipment management operation difficulty is big, is unfavorable for promotion and application.For example current Pressure Curve in Oil Testing Well makes
Yield is measured with Multifunction tank, amount accuracy is low, and the variation of yield is not seen to the well short time of low output.Some Pressure Curve in Oil Testing Well
Using being three Phase Separating-Metering Device, as yield increases, the equipment needed also becomes bulky therewith, cost of investment also with
Increase, and can be related to pressure vessel use management the problems such as.
The above problem increases the production cost and management difficulty of oil well and Pressure Curve in Oil Testing Well, needs to solve.
Summary of the invention
The purpose of this utility model provides equal flows branch path metering oil aiming at drawbacks described above of the existing technology
The measuring equipment of air water well production, reduces the capital investment of oil well and Pressure Curve in Oil Testing Well mating process and metering device, and reduction is produced into
Sheet and management difficulty.
The technical solution of the utility model is: waiting the measuring equipment of flows branch path metering oil gas water well yield, including meter
Device is measured, equipped at least with two branch metric pipelines between intake pipeline and export pipeline, in every branch metric pipeline
Equipped with flow controller；Pressure summary table is mounted on the inlet end of intake pipeline, and metering device connects one point wherein by pipeline
In branch metering pipeline, between flow controller and export pipeline；The import of intake pipeline and the output pipeline of oil gas water well connect,
The outlet of export pipeline and the export pipeline of well head connect.
Compared with the metering method and measuring equipment of existing oil well and formation testing well production, the significant of the utility model uses effect
Fruit is: produced fluid in well is divided into 2 or 2 or more branch metric pipelines, such as two, three, four by the utility model
Item, five etc., each branch metric pipeline installs the flow controller of same size always, wherein the aperture of flow nipple, length and adds
Work parameter is identical, by adjusting the pore size of flow nipple or the quantity for the branch metric pipeline employed, makes liquid with height
The flow nipple in the branch metric pipeline employed is flowed through in or equal to the flow velocity of critical state.Therefore only to wherein branch's meter
Flow instrument is installed on buret road or on-line metering device carries out flow measurement, then with the flow of the branch metric pipeline measured
Total flow can be obtained multiplied by the quantity for the branch metric pipeline employed, and then is learnt using well yield, reached with lower
Measuring cost, realize the purpose measured extensively.
The calculation formula of flow nipple:
Q-amount of liquid
D-flow nipple aperture
P-upstream pressure
R-Reynolds number
Reynolds number is the parameter determined by fluid flow rate, flow nipple aperture, the viscosity of fluid, the density of fluid.
According to above-mentioned formula, under critical state, the flow of flow nipple is flowed through, only the upstream pressure and flow nipple with flow nipple
Geomery it is related, it is unrelated with the downstream pressure of flow nipple.Whether the flow that therefore scene only needs to judge to flow through flow nipple
Reach critical state, it is ensured that the aperture of each flow nipple is consistent, has confirmed the quantity of branch metric pipeline of the fluid through flow nipple, so
Afterwards only to a wherein branch metric pipeline measuring flow, so that it may with branch metric piping flow multiplied by branch metric pipeline
The method of quantity obtains total flow to obtain well yield.
Well yield can be implemented in time using the utility model, and range ability is broad, and the examination estimated is difficult to for yield
Oil gas water well after oil, gas testing well or well stimulation, then when the online metering device of mating installation, can accomplish to settle at one go.This
Metering device used in utility model is not because needing too big flow, so small volume, effectively prevents holding using pressure
The problem of device metering is be easy to cause, to improve the safety of production, reduces management cost and difficulty, and its installation makes
With also becoming simple and convenient.The utility model can significantly reduce labour and transportation cost, shorten formation testing metering cycle, have aobvious
The economic benefit and social benefit and good using effect and application value of work.
