Abstract
The invention discloses a kind of oil flow to measure pipe nipple, including oval gear flowmeter, preceding bend pipe, preceding three-way pipe, U-bend, rear three-way pipe, back elbow.The device is the density variation for utilizing gas-liquid two-phase in Produced Liquid, the initial gross separation of gas-liquid is carried out under gravity, when liquid flows through oval gear flowmeter from device bottom, oval gear flowmeter can accurately measure fluid flow, so as to realize the accurate measurement of fluid flow in Produced Liquid.The principle being mainly characterized by using Gravity Separation of device, carries out the independent measurement of fluid flow in Produced Liquid, avoids influence of the gas to measurement result in Produced Liquid, measuring principle is simple, as a result accurately.
Description
Technical field
The invention belongs to petroleum production engineering field, a kind of specifically oil flow measurement pipe nipple.
Background technology
In high gassiness oil-gas reservoir recovery process, Produced Liquid is often gas-liquid mixture, can only be measured using Conventional meters
The total flow of Produced Liquid, it is impossible to measure fluid flow in Produced Liquid.And accurate measurement Produced Liquid fluid flow is adopted for formulation
Oily scheme is extremely important, for science oil recovery, accurately measures Produced Liquid fluid flow, can extrapolate pump and fill
Full scale, and then pump impulse time is adjusted, oil recovery efficiency is improved, reaches the purpose of energy-saving and emission-reduction.
The content of the invention
For in petroleum production engineering, when Produced Liquid is gas-liquid mixture, existing flowmeter can not accurate measurement fluid flow
Problem, the invention discloses a kind of oil flow to measure pipe nipple.
The technical solution adopted in the present invention is：
The device includes oval gear flowmeter, preceding bend pipe, preceding three-way pipe, U-bend, rear three-way pipe, back elbow.It is antecurvature
Pipe, oval gear flowmeter and back elbow are arranged on device bottom, and U-shaped bend pipe is arranged on device top.During measurement, elliptic gear
Flowmeter works under differential pressure action, and oval gear flowmeter inlet pressure is higher than liquid outlet pressure, therefore, in preceding three-way pipe
Pressure is higher than rear threeway overpressure, and U-shaped bend pipe is close to liquid level at preceding three-way pipe higher than liquid level at rear three-way pipe.Mixed liquor is in the past
After three-way pipe enters device, under gravity, liquid flows out from device bottom through oval gear flowmeter, elliptic gear flow
Measuring out liq flow is measured, gas flows out from device top through U-shaped bend pipe.Certain pressure, pressure size in U-shaped bend pipe be present
Close to rear threeway overpressure size.Gas constantly enters in U-shaped bend pipe, U-shaped curved overpressure rise, three after pressure is more than
During logical overpressure, gas is discharged from rear three-way pipe in U-shaped bend pipe.
Compared with existing metering system, the present invention has advantages below：
1st, the present invention utilizes the effect of gravity, and mixed liquor is carried out to preliminary gas-liquid separation, can accurately measure Produced Liquid
Middle fluid flow.
2nd, apparatus structure is simple, stable performance, and measurement result is accurately and reliably.

Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, there is shown, a kind of oil flow of present invention measurement pipe nipple include oval gear flowmeter (1), preceding bend pipe (2),
Preceding three-way pipe (3), U-bend (4), rear three-way pipe (5), back elbow (6).
Device bottom from left to right successively install before three-way pipe 3, preceding bend pipe 2, oval gear flowmeter 1, back elbow 6, after
Three-way pipe 5；Device top is from left to right installed by preceding three-way pipe 3, U-shaped bend pipe 4, rear three-way pipe 5 successively.During using the device, dress
Put and be horizontally mounted, ensure oval gear flowmeter 1 under, U-shaped bend pipe 4 is upper.
Between preceding three-way pipe 3 and U-shaped bend pipe 4, between preceding three-way pipe 3 and preceding bend pipe 2, U-shaped bend pipe 4 and rear three-way pipe 5 it
Between, between preceding bend pipe 2 and oval gear flowmeter 1, between oval gear flowmeter 1 and back elbow 6, back elbow 6 and rear threeway
Between pipe 5, connected using ring flange, sealing ring is installed to ensure the sealing of device between ring flange.
During measurement, oval gear flowmeter 1 works under differential pressure action, and the inlet pressure of oval gear flowmeter 1 is higher than
Liquid outlet pressure, therefore, pressure is higher than pressure in rear three-way pipe 5, U-shaped bend pipe 4 liquid at preceding three-way pipe 3 in preceding three-way pipe 2
Face is higher than liquid level at rear three-way pipe 5.Mixed liquor is after preceding three-way pipe 3 enters device, and under gravity, liquid is from device bottom
Flowed out through oval gear flowmeter 1, oval gear flowmeter 1 measures fluid flow, and gas is from device top through U-shaped bend pipe 4
Outflow.Certain pressure in U-shaped bend pipe 4 be present, pressure size is close to pressure size in rear three-way pipe 5.Gas constantly enters U-shaped
In bend pipe 4, pressure rise in U-shaped bend pipe 4, when pressure is more than pressure in rear three-way pipe 5, gas is from rear threeway in U-shaped bend pipe 4
Pipe 5 is discharged.
