Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of plunger oil well weighing flowmeter is provided, and has eliminated pressure, temperature-density, viscosity, the impact containing factors such as sand, the content of wax and gassiness on oil well measurement, and precision is high, highly versatile.
The purpose of this utility model is achieved in that a kind of plunger oil well weighing flowmeter, the oil cylinder of weighing, feed liquor pipeline and the fluid pipeline that comprise lateral arrangement, the below of feed liquor pipeline and fluid pipeline is connected respectively adjustable support, the oil cylinder of weighing is arranged on the below of feed liquor pipeline and fluid pipeline, weigh and be connected the first LOAD CELLS between oil cylinder and feed liquor pipeline, between weigh oil cylinder and fluid pipeline, be connected the second LOAD CELLS; Connect the first ball valve seat on described feed liquor pipeline, the first ball valve seat connects the first electrical ball valve, the first electrical ball valve arranges three hydraulic fluid ports, first hydraulic fluid port of the first electrical ball valve is connected with the feed liquor pipeline, second hydraulic fluid port of the first electrical ball valve is connected with the left end of the oil cylinder of weighing, and the 3rd hydraulic fluid port of the first electrical ball valve is connected with the right-hand member of the oil cylinder of weighing; Connect the second ball valve seat on described fluid pipeline, the second ball valve seat connects the second electrical ball valve, the second electrical ball valve arranges three hydraulic fluid ports, first hydraulic fluid port of the second electrical ball valve is connected with the fluid pipeline, second hydraulic fluid port of the second electrical ball valve is connected with second hydraulic fluid port of the first electrical ball valve, and the 3rd hydraulic fluid port of the second electrical ball valve is connected with the 3rd hydraulic fluid port of the first electrical ball valve.
During metering, produced liquid in oil well continuously flows into the oil cylinder of weighing, the oil cylinder of weighing comprises cylinder body and plunger, import and export electric T-shaped valve (electrical ball valve) is controlled flow direction, utilize the kinetic energy of fluid self to promote the reciprocating motion that plunger goes round and begins again in cylinder body, liquid in cylinder body is out while advancing, continuously flow into and discharge.When plunger arrives the container side, LOAD CELLS is weighed to cylinder body (filled with fluid and gas), finally adds up and just can calculate the quality of three-phase flow.Can calculate again the relevant parameter of the oil such as oil mass, the water yield, gas-oil ratio, gas, water three-phase by oil density, formation water density, the parameter such as moisture.
Concrete steps are as follows:
1, crude oil enters first hydraulic fluid port of the first electrical ball valve from the feed liquor pipeline, flow out and enter the cylinder body left-hand end from second hydraulic fluid port, promote plunger and slide from left to right, make crude oil in cylinder body flow to first hydraulic fluid port from right-hand end through the 3rd hydraulic fluid port of the second electrical ball valve, go out from the drain pipe linear flow.When plunger slides into the low order end of plunger container, now the crude oil of whole cylinder body is to remain static, and the LOAD CELLS measurement quality is M1.Pass in and out oily electric three way cock commutation simultaneously.
2, crude oil enters first hydraulic fluid port of the first electrical ball valve from the feed liquor pipeline, flow out and enter the cylinder body right-hand end from the 3rd hydraulic fluid port, promote plunger slips of turning left from the right side, make the interior crude oil of cylinder body flow to first hydraulic fluid port from left-hand end through second hydraulic fluid port of the second electrical ball valve, go out from the drain pipe linear flow.When plunger slides into the high order end of plunger container, now the crude oil of whole cylinder body is to remain static, and the LOAD CELLS measurement quality is M2.Pass in and out oily electric three way cock commutation simultaneously.
3, repeating step 1 and 2, just can obtain M3, M4 ... Mn.
4, accumulative total (M1-M0)+(M2-M0)+... (Mn-M0) just can calculate the crude oil accumulative total quality (M0 is the flow meter quality) in the corresponding time.
For the ease of detected pressures, connect the first pressure transmitter on described feed liquor pipeline.
The same, connect the second pressure transmitter on the fluid pipeline.
In order to prevent that plunger from stopping up in cylinder body, cause and build the pressure, be connected with the constant pressure turn on valve between feed liquor pipeline and fluid pipeline.
