Described air guide pipeline 2 is divided into two-way before being connected with described measuring tank group, passes through the top of the No.1 measuring tank 5 all the way
Access inside No.1 measuring tank 5, another way is accessed inside No. two measuring tanks 6 by the top of No. two measuring tanks 6；It is described enter
The a port of liquid triple valve 4 is connected with catheter 3, and liquid inlet tee joint valve 4 other two port enters with No.1 measuring tank 5 respectively
Mouthful connected with the entrance of No. two measuring tanks 6, the No.1 measuring tank 5 export and the outlet of No. two measuring tanks 6 respectively with discharge opeing
Two in 7 three ports of triple valve are connected, and another port of the discharge opeing triple valve 7 is connected to the analyzer of water content 8
Entrance.
The also parallel connection of described heating tank 10 has the first bypass pipe 9, and described booster pump 11, which is also connected in parallel, second
Bypass pipe 12.
The catheter 3 is U-shaped catheter.
Described liquid inlet tee joint valve 4 and discharge opeing triple valve 7 is magnetic valve.
The inner bottom of described No.1 measuring tank 5 and No. two measuring tanks 6 is provided with pressure sensor 14.
Carry out liquid from one-well metering pipeline and initially enter knockout drum 1 to separate most of gas, then pass through U-shaped drain
Pipe 3, the setting of U-shaped catheter 3 can avoid gas from entering measuring tank group, the pipe in catheter 3 to measuring tank group by this circuit
The liquid inlet tee joint valve 4 of one magnet control is set on road, for control catheter 3 come liquid be into No.1 measuring tank 5 or
No. two measuring tanks 6；The discharge opeing triple valve of magnet control is connected with the export pipeline of No.1 measuring tank 5 and No. two measuring tanks 6
7, for controlling the discharge opeing of No.1 measuring tank 5 and No. two measuring tanks 6.The inner bottom of No.1 measuring tank 5 and No. two measuring tanks 6 is equal
Pressure sensor 14 is installed, the quality of feed liquor is calculated by measuring the specified point pressure change into flow container.Two metering tank decks
Portion is connected with the conductor pipeline 2 that knockout drum is drawn, and is realized and connected by the air guide pipeline 2 at the top of two measuring tanks.
Specific implementation step is as follows：
Step 1, the metering of Liquid output, it is specially：
Step 1.1, after carrying out liquid via knockout drum 1, gained liquid passes sequentially through U-shaped catheter 3 and liquid inlet tee joint valve
4, controlled by liquid inlet tee joint valve 4 and enter No.1 measuring tank 5 or No. two measuring tanks 6 come liquid, discharge opeing triple valve 7 controls No.1 measuring tank
5 or the discharge opeing of No. two measuring tanks 6, control the one of feed liquor of two measuring tanks to measure by liquid inlet tee joint valve 4 and discharge opeing triple valve 7
When another measuring tank carry out discharge opeing, during this in real time collection two pressure sensors 14 data, will work as tank in liquid
Setting value shown in corresponding pressure sensor 14 is highest pressure P when body is charged to always high 90% in tank inner chambermax；It will work as in tank
Setting value shown in corresponding pressure sensor 14 is minimum pressure P when liquid drains into always high 10% in tank inner chambermin, in collection two
During the data of individual pressure sensor 14, when the measurement pressure of wherein any one tank reaches the highest or minimal pressure of setting
During intensity values, the feed liquor of two measuring tanks, discharge opeing state are switched by liquid inlet tee joint valve 4 and discharge opeing triple valve 7, meanwhile, record two
The current pressure values of individual pressure sensor 14, the pressure be now converted into the measuring tank of liquid status are designated as PL；
Step 1.2, when No.1 measuring tank 5 or No. two measuring tanks 6 meet pressure record condition next time, feed liquor three is passed through
Port valve 4 and discharge opeing triple valve 7 switch feed liquor, the discharge opeing state of two measuring tanks again, while record two pressure sensors 14
Pressure values, the pressure for being converted to the measuring tank of discharge opeing state is PH；
Step 1.3, Liquid output is calculated：The measuring tank twice is measured to enter, enter measuring tank group during discharge opeing State Transferring
The change of the measured value of liquid build-up of pressure sensor 14 turn to PH-PL, it is into the quality of measuring tank group liquid during this period：
M=A* (PH-PL)/g
In formula：The measuring tank of m-twice enters, enters the liquid quality of measuring tank group during discharge opeing State Transferring；
The projected area of A-No.1 measuring tank 5 and No. two inner chambers of measuring tank 6 in vertical direction；
PH- measuring tank is converted to the liquid pressure that discharge opeing state is instantaneously surveyed；
PL- measuring tank is converted to the liquid pressure instantaneously surveyed into liquid status；
G-acceleration of gravity；
This metering process is alternately repeated progress between two measuring tanks, and constantly measurement obtains the liquid into measuring tank group
Quality, two measuring tanks are entered every time, can obtain accordingly to enter after measured liquid quality is cumulative during discharge opeing State Transferring, discharge opeing
What state conversion frequency corresponded to the time carrys out liquid quality；
Step 2, the detection of moisture content after liquid measures is produced, is specially：
Liquid by analyzer of water content 8 measure moisture content, by the detection can to moisture content respectively obtain water and
Oil mass；
mWater=mLiquid*k
mOil=mLiquid*(1-k)
In formula：mLiquid- carry out liquid quality；
mWater- carry out water content in liquid；
mOil- the oil mass come in liquid；
K-moisture content.
Need to produce liquid during heating into heating tank heating 10, production liquid directly walks the first bypass pipe 9, it is necessary to increase when being not required to heating
Produced during pressure liquid enter booster pump 11 be pressurized it is outer defeated, it is not necessary to liquid is produced when being pressurized and walks the second bypass pipe 12 and is directly entered outside outer defeated header 13
It is defeated；
A kind of Weighing type single well metering device of the present utility model, it is cumulative by carrying out metering to production liquid weight, realize production
The metering of liquid total amount, by analyzer of water content measure moisture content, calculate oil production and aquifer yield, liquid measure and tolerance fluctuation compared with
When big, individual well production fluid can accurately be measured, it is simple in construction.
