Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model well water amount on-line measuring device schematic diagram.
The specific embodiment
Embodiment 1:
As shown in Figure 1, present embodiment provides a kind of well water amount on-line measuring device, comprises data acquisition unit and data processing unit;
Wherein, data acquisition unit comprises data acquisition pipeline 3, pressure sensor 5 and control valve 2, control valve 2 is installed on the oil well trunk line 1, data acquisition pipeline 3 two ends are connected across on the trunk line 1 of control valve 2 both sides, have a vertical section on the data acquisition pipeline 3, preferred data acquisition pipeline is a U-shaped, also can be other shapes, and vertical section is positioned at its input (also can be positioned at output).Pressure sensor 5 is arranged on the bottom of this vertical section, utilize the pressure that crude oil mixed liquor is produced in 5 pairs of vertical sections of this pressure sensor to detect, and utilize control valve 2 to control the break-make of trunk lines 1, to guarantee that the crude oil mixed liquor in the vertical section is the oil well mixed liquor of output in real time; Data processing unit receives the data that pressure sensor 5 is gathered, and become to determine that according to the density of crude oil mixed liquor in the same oil well and its water content functional relation handles data, finally obtain instantaneous water-retention value and stage water-retention value in the crude oil mixed liquor, instantaneous water-retention value is the water-retention value that control valve 2 is opened crude oil mixed liquor in the moment data acquisition pipeline 3, and the stage water-retention value is the average of the at interval interior instantaneous water-retention value of certain hour.On-line measuring device also has display unit 6, and 6 couples of resulting results of data processing unit show in real time by this display unit.
Pressure bottom the mixing material of the crude oil of the well water amount on-line measuring device that present embodiment provides by measuring given volume and water is determined its density, utilizes the water content of mixing material of crude oil and water and the water content that principle that its density has definite functional relation calculates the mixing material of crude oil and water again.When control valve 2 open instantaneous, be full of liquid and be in relative static conditions in the data acquisition this moment pipeline 3, the pressure of data acquisition pipeline 3 bottoms passes to microprocessor in the data processing unit through the program instantaneous water-retention value of controlled valve 2 when opening that convert by pressure sensor 5, when control valve 2 is closed, liquid mobile liquid with original relative static conditions in data acquisition pipeline 3 replaces out, when opening once more, control valve 2 just can record an instantaneous water-retention value once more, if set one day inner control valve 2 N unlatching arranged, then can detect N water-retention value and average water-retention value thereof, water-retention value can be presented on the display unit 6.In order to guarantee certainty of measurement, the diameter of data acquisition pipeline 3 is compared with trunk line 1 should be as far as possible little.
The using method of this well water amount on-line measuring device:
1, well water amount on-line measuring device is installed in the individual well well head.
2, connect power supply and this well oil density input data processing unit that will obtain in advance (if oil density is because of changing the former thereby input that will upgrade in time when changing such as layer production).
3, set the 2 automatic opening times of control valve at interval.
4, control valve 2 is opened once automatically, and display unit 6 will show instantaneous water-retention value and the interior average water-retention value of time in stage when opening.
This method requires control valve 2 to be in normally off, and most times of crude oil are that the data acquisition pipeline 3 by U-shaped flows through, and such pipeline can cause the resistance when flowing to strengthen, and influences the flow velocity of crude oil.So also can take another kind of method measures.
Promptly when not measuring, make control valve 2 be in normally open, when needs are measured, earlier control valve 2 is closed a period of time, and then open, the instantaneous water-retention value in the time of at this moment can recording control valve 2 unlatchings.Can measure the average water-retention value in the time in stage equally, like this in most times, crude oil is to flow through through the straight trunk line 1 and data acquisition pipeline 3 two passes of U-shaped, and the resistance when flowing can reduce greatly, can not make a big impact to the mobile of crude oil.
The well water amount on-line measuring device of this kind structure can real-time online detects the water content in the crude oil.
In order to realize online remote detection, this well water amount on-line measuring device also comprises data transmission unit and is positioned at long-range computer 10, data transmission unit specifically comprises being positioned at and recovers the oil on-the-spot and the signal projector 4 that links to each other with pressure sensor 5 and be positioned at the signal receiver 7 that also links to each other with computer 10 by line 9 away from the scene of recovering the oil, signal projector 4 adopts wireless mode that instantaneous water-retention value and stage water-retention value remote data are sent to signal receiver 7, signal receiver 7 has display screen 8, be used to show instantaneous water-retention value and stage water-retention value data, signal receiver 7 is sent to computer 10 with instantaneous water-retention value and stage water-retention value data, computer 10 is used for instantaneous water-retention value and stage water-retention value data are presented at the screen of computer 10, and these data are stored, analyze.
The well water amount on-line measuring device that present embodiment provides can real-time online detects the water content in the crude oil, and can data be sent in the long-range computer 10 by wireless transmission, realize remote measurement, and can demonstrate the water content of crude oil on display unit at the scene 6 and the long-range computer.
In order to simplify this well water amount on-line measuring device, data processing unit also can be away from the oil well setting, to realize online remote detection to oil well crude oil mixed liquor water content, be specially the function that realizes data processing unit and display unit 6 by computer 10, be that data transmission unit only transmits the pressure data that collects and gives computer 10, realize the calculating of water content in crude oil by computer 10.
This well water amount on-line measuring device can real-time online detects the water content in the crude oil, and can data be sent in the long-range computer 10 by wireless transmission, realize remote measurement, with last a kind of comparing, function by computer realization data processing unit and display unit 6, the on-the-spot device that recovers the oil is easier, but the water content data only show in computer 10, and in the on-the-spot display unit 6 of recovering the oil, do not show, so display unit 6 can be set or only allow display unit 6 show pressure data.
Above-mentioned with reference to embodiment to description of the present utility model, be illustrative rather than determinate, therefore, should belong within the protection domain of the present utility model in the variation and the modification that do not break away under the utility model general plotting.
