The fluid yield metering device of the wellhead of the pumped well belongs to the metering device technology field. A current signal output end of a current converter of an oil pumping motor is connected with a current signal input end of an intelligent integrating instrument; one pressure signal output and input end of the intelligent integrating instrument is connected with a signal interface of a first pressure transmitter; the other pressure signal output and input end of the intelligent integrating instrument is connected with a signal interface of a second pressure transmitter; a first flow switch is connected with a second flow switch; and the first flow switch and the second flow switch are respectively connected with the first pressure transmitter and the second pressure transmitter. The fluid yield metering device of the wellhead of the pumped well has the advantages of being capable of directly metering fluid yield of the pumped well without liquid-gas separation, small in investment, easy to achieve and capable of continuously metering, not needing time conversion, overcoming metering deviations caused by interval fluid yield of the pumped well and being high in reliability of a metering result, high in accuracy and simple to operate.
Description
Technical field
The present invention relates to a kind of rod-pumped well well head production fluid metering device, belong to the oil well metering device technical field.
Background technology
The oil field is measured the well head production fluid and is all adopted first parting liquid gas to carry out the metering of production fluid gas more at present, the employed technology of this method is comparatively complicated, discontinuous operating mode to oil well adapts to relatively poor, measuring accuracy and result's confidence level can't be confirmed, also have more other ways to the metering of liquid gas blending agent is domestic, but most in the experimental stage, performance difficulty is more.
Summary of the invention
The objective of the invention is in order to solve the problem that above-mentioned prior art exists.Being the oil field to the well head production fluid, metering all adopts first parting liquid gas to carry out the metering of production fluid gas again, and the employed technology of this method is comparatively complicated, the discontinuous operating mode of oil well is adapted to relatively poor, and measuring accuracy and result's confidence level can't be confirmed.And then provide a kind of rod-pumped well well head production fluid metering device.
The objective of the invention is to be achieved through the following technical solutions:
A kind of rod-pumped well well head production fluid metering device, comprise the oil pumping motor current converter, intelligent integral-counting instrument, first pressure transmitter, second pressure transmitter, first flow switch and second flow switch, the current signal output end of described oil pumping motor current converter is connected with the current signal input of intelligent integral-counting instrument, a pressure signal I/O of intelligent integral-counting instrument is connected with the signaling interface of first pressure transmitter, another pressure signal I/O of intelligent integral-counting instrument is connected with the signaling interface of second pressure transmitter, the first flow switch is connected with second flow switch, and the first flow switch is connected with second pressure transmitter with first pressure transmitter respectively with second flow switch.
Beneficial effect of the present invention: device of the present invention need not separate through liquid gas, can directly measure the production fluid amount of oil well, but the present invention has small investment, easily implements continuous metering, the conversion that do not take time, customer service the oil well deviation brought to metering of production fluid intermittently, measure credible result degree height.The present invention also has precision height, simple operation and other advantages.
Description of drawings
Fig. 1 is the structural representation of a kind of rod-pumped well well head of the present invention production fluid metering device.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing: present embodiment has provided detailed embodiment being to implement under the prerequisite with the technical solution of the present invention, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, a kind of rod-pumped well well head production fluid metering device that this example is related, comprise oil pumping motor current converter 1, intelligent integral-counting instrument 2, first pressure transmitter 3, second pressure transmitter 4, first flow switch 5 and second flow switch 6, the current signal output end of described oil pumping motor current converter 1 is connected with the current signal input of intelligent integral-counting instrument 2, a pressure signal I/O of intelligent integral-counting instrument 2 is connected with the signaling interface of first pressure transmitter 3, another pressure signal I/O of intelligent integral-counting instrument 2 is connected with the signaling interface of second pressure transmitter 4, first flow switch 5 is connected with second flow switch 6, and first flow switch 5 is connected with second pressure transmitter 4 with first pressure transmitter 3 respectively with second flow switch 6.
Under normal condition, the oil pumper production fluid can be calculated by following formula
Q：0.144SL
S is oil pumping pump barrel cross section cm
2, L is for whenever taking out stroke m once, and Q is 24 hours production fluid amount m
3, owing to reasons such as the degree of filling of pump, leakages, whenever to take out and once all do not reach theoretical value, contribution of the present invention is to determine that the Q=0.144SLh of dynamic correction factor K revises, and makes Q=∑ KSL.K should be coefficient of dynamics, K should equal K=f (I*P), when the no flow signal of flow switch output is K=0, I, P is gathered by oil pumping motor current converter and pressure transmitter respectively, the dead point of stroke up and down of minimum and maximum definite oil pumper of electricity consumption flow variables of the present invention and pressure variations, the K value is by electric current in a stroke, pressure history is determined, the method of determining be earlier by calibration curve with gather curve ratio, adopt the method for tabling look-up to determine by intelligent integral-counting instrument, intelligent integral-counting instrument can be according to the start and stop of production fluid situation control oil pumper, thereby reach purpose of energy saving, he can carry out analyzing and processing to creation data, carry out production management, all data all can be uploaded by the internet, can realize the oil pumper telemanagement.
The above; only be the preferable specific embodiment of the present invention; these specific embodiment all are based on the different implementations under the general idea of the present invention; and protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
