Abstract
A slurry tank with a mixing chamber and a balancing chamber relates to a combined oil field well cementing slurry apparatus characterized in that a baffle board lower than the shell forms two upper portion connected chambers in the tank body, wherein the top and the bottom of the mixing chamber are respectively provided with a diffusing groove interface and a circulating pump interface and the bottom of the balancing chamber is provided with a slurry apparatus interface, the two chambers are both provided with agitators. When mixing slurry, the recycle mixing is moving between the mixing chamber and the high-energy agitator of the slurry apparatus, the mixed slurry overflows the baffle board and enters the balancing chamber. In the process of overflowing baffle board and being agitated, the slurry releases the air in it and is further mixed and pumped.
Description
Affiliated technical field:
The utility model relates to the device of the reinforcing oil well mud that is mixed, slurry tank especially wherein.
Background technology:
In the well cementing operation of ocean and land field produces, use mud with setting density.Being mixed of mud can be finished by device shown in Figure 2: clear water centrifugal pump 13 produces the high pressure clear water and is injected in the high energy mixers 15, in blender, form the current of high velocity jet, the negative pressure that is produced by high-speed jet sucks dry cement from ash can 11, the two is after fully mixing, entering cyclone type spreading grooves 10 removes gas and is discharged in the slurry tank 12 with agitator 3, circulation pump 14 turns back to blender 15 and virgin material with the first mixed mud in the slurry tank 12 and carries out secondary or compound repeatedly, and finished product mud enters plasma discharge equipment from interface 4 simultaneously.Because the flow velocity of mud is fast through blender and spreading grooves the time, the time short, so still there is the even phenomenon of certain gas and density unevenness in the mud unavoidably, these can influence the quality of well cementation.
Summary of the invention:
The purpose of this utility model provides a kind of slurry tank with mixing chamber and compensating chamber, and its problem that will solve is: remove gas residual in the mud, and make mud density more even.
Address the above problem, be to take slurry tank is improved, scheme is, slurry tank with mixing chamber and compensating chamber has tank body, is arranged on the spreading grooves interface at tank body top, the circulation pump interface that is arranged on tank base and plasma discharge equipment interface, it is characterized in that, has a dividing plate that is lower than tank skin in the tank body, to form two chambers that top communicates in the tank body, spreading grooves interface and circulation pump interface is a chamber therein, and the plasma discharge equipment interface is at another chamber.In described two chambers, the chamber of first line of a couplet spreading grooves second line of a couplet circulation pump, be mixing chamber, the chamber of second line of a couplet plasma discharge equipment is compensating chamber, in each chamber agitator is set, when being mixed mud, circulation is blended between mixing chamber and the high energy mixers to be carried out, and the mud that mixes covers dividing plate and enters compensating chamber, through stirring, be pumped again.
Slurry tank after the improvement, the chance that mud is back and forth mixed increases, and mud discharges gas wherein in the process that covers dividing plate and be stirred, and further mixing.So the utility model can effectively be eliminated gas residual in the mud, and can make the density of mud even.The volume of slurry mixing tank has obtained the increase of several times simultaneously, makes small-sized batch mix slurry and is achieved.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the principle schematic of device of mud of being mixed.
The specific embodiment:
Referring to Fig. 1, dividing plate 6 vertically is set in tank body 7, make to form mixing chamber 1 and compensating chamber 2 in the tank body, the height of dividing plate 6 will be lower than the wall height of tank body 7, is used for mud and covers, dividing plate 6 near jar at the bottom of the position, closable connected entrance 5 is set, uses spreading grooves interface 8 and circulation pump interface 9 during for the cleaning tank body, be arranged at the top and the bottom of mixing chamber 1 respectively, plasma discharge equipment interface 4 is arranged at the bottom of compensating chamber 2.Mix and balanced better effects if for making, agitator 3 can all suspend in mixing chamber 1 and compensating chamber 2.
Claims (3)
1. the slurry tank that has mixing chamber and compensating chamber, have tank body, be arranged on the spreading grooves interface at tank body top, the circulation pump interface that is arranged on tank base and plasma discharge equipment interface, it is characterized in that, has a dividing plate that is lower than tank skin in the tank body, two chambers that top communicates will be formed in the tank body, spreading grooves interface and circulation pump interface is a chamber therein, and the plasma discharge equipment interface is at another chamber.
2. the slurry tank with mixing chamber and compensating chamber according to claim 1 is characterized in that, in described two chambers agitator is set respectively.
3. the slurry tank with mixing chamber and compensating chamber according to claim 1 and 2 is characterized in that, has closable connected entrance at dividing plate near a jar bottom.
