The utility model is in order to make up the deficiencies in the prior art, provide a kind of rational in infrastructure, constructability, the acid solution of acidizing and fracturing fluid, viscosity, density entirety are mixed, without lamination, improve the mixture quality of acidizing and fracturing fluid, be convenient to remove the acidizing and fracturing fluid blending device of foam, solve problems of the prior art.
The utility model is achieved by the following technical solution:
A kind of acidizing and fracturing fluid blending device, comprise blending tank and foam process tank, several blending tank inlets be connected with blending tank inside are circumferentially with along blending tank in the side wall upper part of blending tank, a blending tank liquid outlet be connected with blending tank inside is provided with in the lower sidewall of blending tank, the guide shell of a funnel type is provided with in the inside upper part of blending tank, blending tank madial wall below the top of guide shell and blending tank inlet is connected, one upper end being vertically located at the shaft inside blending tank is passed guide shell center and is connected with a motor after passing the top of blending tank, shaft below guide shell is provided with several paddles, an endless tube is arranged with at the lower outside of guide shell, the side of endless tube is connected with the blending tank foam outlet be located at below blending tank inlet by a tube connector, in the inner side of endless tube, outside and lower wall evenly offer several aspirating holes, described blending tank foam outlet is connected by the entrance of pipeline with a blower fan, the outlet of blower fan is connected with the foam process tank foam inlet being located at foam process tank top by pipeline, the lower sides of foam process tank is provided with a foam process tank liquid outlet, a heater is provided with in the inner side of foam process tank.
Each blending tank inlet is connected with outside material pipeline respectively by a blending tank feed tube, and blending tank feed tube is 40 °-60 ° with the side wall angle of blending tank in the horizontal direction.
The bus of described guide shell and the angle of blending tank central axis are 45 °-60 °.
The beneficial effects of the utility model are: this acidizing and fracturing fluid blending device, rational in infrastructure, constructability, occurs mutually to liquidate after various additive enters blending tank and forms swirling and continue to fall, thus realize the preliminary mixing of additive on the inner side conical surface of guide shell.Additive to drop to behind blending tank bottom under the further stirring of paddle, achieve the abundant mixing between each additive of acidic fracturing fluid, the acid solution of acidizing and fracturing fluid, viscosity, density entirety are mixed, improve the mixture quality of acidizing and fracturing fluid without lamination, ensure that acidic fracturing fluid is to the acidifying of Oil/gas Well, fracturing effect.Acidizing and fracturing fluid is extracted out at a large amount of foams sucked, produce in whipping process, the aspirating hole of acid mist on endless tube, enters in foam process tank, avoids foam, acid mist accumulates in impact operation above liquid.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the distribution schematic diagram of blending tank feed tube outside blending tank in Fig. 1.
In figure, 1 blending tank, 2 foam process tanks, 3 blending tank inlets, 4 blending tank liquid outlets, 5 guide shells, 6 shafts, 7 motors, 8 paddles, 9 endless tubes, 10 tube connectors, 11 blending tank foam outlets, 12 aspirating holes, 13 blower fans, 14 foam process tank foam inlet, 15 foam process tank liquid outlets, 16 heaters, 17 blending tank feed tubes.
(5) detailed description of the invention
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As as shown in Fig. 1-Fig. 2, this embodiment comprises blending tank 1 and foam process tank 2, several blending tank inlets 3 be connected with blending tank 1 inside are circumferentially with along blending tank in the side wall upper part of blending tank 1, a blending tank liquid outlet 4 be connected with blending tank 1 inside is provided with in the lower sidewall of blending tank 1, the guide shell 5 of a funnel type is provided with in the inside upper part of blending tank 1, blending tank 1 madial wall below the top of guide shell 5 and blending tank inlet 3 is connected, one upper end being vertically located at the shaft 6 inside blending tank 1 is passed guide shell 5 center and is connected 7 with a motor after passing the top of blending tank 1, shaft below guide shell is provided with several paddles 8, an endless tube 9 is arranged with at the lower outside of guide shell 5, the side of endless tube 9 is connected with the blending tank foam outlet 11 be located at below blending tank inlet 3 by a tube connector 10, in the inner side of endless tube 9, outside and lower wall evenly offer several aspirating holes 12, described blending tank foam outlet 11 is connected by the entrance of pipeline with a blower fan 13, the outlet of blower fan 13 is connected with the foam process tank foam inlet 14 being located at foam process tank 2 top by pipeline, the lower sides of foam process tank 2 is provided with a foam process tank liquid outlet 15, a heater 16 is provided with in the inner side of foam process tank.
