Description
Technical field
The utility model relates to metering device, relates in particular to a kind of oil gas well well yield automatically-controlled continuous metering device.
Background technology
At present the widely used vertical metering separator in oil field in all kinds of measurement technologies in oil field shared ratio more than 85%; For stable oil well; The precision of this kind measurement technology can satisfy production management and require; But,, can't realize gauging accurately to fluctuation, belching well because it can not realize the continuous quantity functional oil for fluctuation, oil well intermittently.Existing indicator card gauging is owing to be to disperse sampling to calculate the output of individual well through certain jig frequency, and non-continuous, representativeness is relatively poor as a result for it.The heterogeneous metering device of rotational flow separation is owing to be metering instrument; The effect of its measuring accuracy and rotational flow separation has very big relation; Separating effect directly influences the measuring accuracy of device; And in fact the operating mode of every mouthful of well varies, and is difficult to guarantee that every mouthful of well comes liquid can both reach desirable separating effect, and measuring accuracy is difficult to guarantee.Because the traditional vertical separator metering device in each oil field is occupied an leading position at present, its metering process flow process is fixing, thoroughly change, and needs great amount of investment, and is concerning any one oil field, all unrealistic.In a word, even though existing metering device measuring accuracy is higher, complex structure, maintenance period is short, and cost is high, operating personnel's technical level is required high.
Summary of the invention
The purpose of the utility model is intended to overcome the deficiency of prior art, provides a kind of oil well simple in structure, with low cost, easy to operate, that be fit to fluctuation, intermittently oil gas well yield metering to control metering device automatically.
The purpose of the utility model can realize through following technical measures:
This metering device is connected with content gauge outside tank body; Be divided into two cavitys that volume equates with dividing plate in the tank body; In each cavity separating cyclone tube is arranged; One end is communicated with the import electric T-shaped valve through the other end of the feed tube that tank body top is communicated with separating cyclone tube, and tank body is connected with the content gauge that is provided with the automatic control of liquid appearance that is communicated with two cavitys respectively outward, and an end is communicated with the outlet electric T-shaped valve through the other end of the drain pipe that tank base is communicated with separating cyclone tube.
The purpose of the utility model also can realize through following technical measures:
The water bag also was communicated with two cavitys and two content gauges respectively at the bottom of the bottom of tank body was connected with two; In the tank body of separating cyclone tube top the deflection plate that connects dividing plate is arranged; The bottom baffles that connects drain pipe is arranged at the bottom in the tank body; The tank body top is provided with safety valve.
That adopts in the vertical separator of prior art is monomer list chamber, single content gauge, the gas balanced structure is arranged.The utility model adopts the structure of monomer two-chamber, automatic control of liquid appearance, no gas balance; Compared with prior art; The utility model is applicable to the oil gas well well yield metering of all kinds of oil gas fields; It has overcome the drawback of gauging continuously of traditional vertical eliminator, is fit to fluctuation, the intermittently metering of oil gas well, has simple in structure, easy to operate, with low cost, safety and environmental protection and can improve effectively again that individual well particularly fluctuates, the advantage of the production metering of oil wells degree of accuracy intermittently.
The utility model can be under the situation that increases a small amount of investment, solves in the puzzlement field produces the particularly problem of the oil gas metering precision of fluctuation, belching well.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Water bag, 12-tank body, 13-dividing plate, 14-content gauge, 15-cavity at the bottom of 1-safety valve, 2-deflection plate, 4-feed tube, 5-import electric T-shaped valve, 6-separating cyclone tube, 7-automatic control of liquid appearance, 8-bottom baffles, 9-drain pipe, 10-outlet electric T-shaped valve, the 11-.
The specific embodiment
This metering device main part is designed to 1 meter of a diameter, height is about 2 meters tank body 12; Two ends are the cylinder on protruding top; The top is provided with safety valve 1; Be divided into two cavitys 15 that volume equates with dividing plate 13 in the tank body 12, have a little slit that two cavitys 15 are communicated on dividing plate 13 tops, in each cavity 15 separating cyclone tube 6 is arranged; One end is communicated with import electric T-shaped valve 5 through the other end of the feed tube 4 that tank body 12 tops are communicated with separating cyclone tube 6; The deflection plate 2 that connects dividing plate 13 is arranged in the tank body 12 of separating cyclone tube 6 tops, the other end that tank body 12 is outer to be connected with the drain pipe 9 that the content gauge that is provided with automatic control of liquid appearance 7 14, one ends that are communicated with two cavitys 15 respectively are communicated with separating cyclone tube 6 through tank body 12 bottoms with export electric T-shaped valve 10 and be communicated with; The bottom baffles 8 that connects drain pipe 9 is arranged at the bottom in the tank body 12, and water bag 11 also was communicated with two cavitys 15 and two content gauges 14 respectively at the bottom of the bottom of tank body 12 was connected with two.It is a pair of working cell that liquid mouth and left side leakage fluid dram are come in the right side, and the left side comes liquid mouth and right side leakage fluid dram to be another working cell.During beginning, when import electric T-shaped valve 5 action arrival liquid get into cavity 15 tops, right side through inlet, liquid natural subsidence after deflection plate 2 separates; Along with the increase of liquid measure, the liquid level in the content gauge of right side rises gradually, and liquid level arrives to set under the liquid level and prescribes a time limit; Begin during right side content gauge 14 quantifiers; Prescribe a time limit when liquid level arrives on the liquid level, the right side timing finishes, and preserves metering time t1 simultaneously; At this moment import electric T-shaped valve 5 moves with outlet electric T-shaped valve 10; The fluid passage switches to left side cavity 15 feed liquors, 15 discharge opeings of right side cavity, and cavity 15 liquid levels in left side rise; Liquid level arrives to be set when beginning quantifier in limited time under the liquid level; Prescribe a time limit when liquid level arrives on the liquid level, cavity 15 meterings in left side finish, record rise time t2.At this moment import electric T-shaped valve 5 and 10 actions of outlet electric T-shaped valve, cavity 15 imports in left side are closed, are exported and open, and cavity 15 imports in right side are opened, port closing, and liquid is discharged by 15 outlets of left side cavity, circulates during the next quantifier of right side cavity 15 beginnings.So repeatedly, the total metering time t=t1+t2+t3+t4++tn of record.Accomplish the calculating of output at last by the oil gas integrating instrument.Thereby realize the purpose of continuous gauging.
