Description
The utility model belongs to a kind of oilfield drilling technology, particularly pressure break and well shaft fixing technology of being used for and joins extraordinary conveyance vehicle for soup.
Current oil field does not also have special liquid distributing pump vehicle, before the pressing crack construction, prepares soup at make-up station, and it is standby to be transported to the camp site large storage tank of packing into tank car.In order to prevent precipitation, also need carry out widely different stream before the use and stir.Because the mixed liquor herb liquid generally only accounts for about 1%, therefore the overwhelming majority of transporting is a clear water, causes great waste.Particularly this method dosing is of poor quality, can not satisfy the requirement of technology.
Applicant is at " liquid truck that is used for oilfield " (application number: 88221294) supply water, join the requirement for soup though can satisfy cement job of first to file, but because the soup ratio of its preparation is inaccurate, can not directly monitor and regulate, still do not meet the needs of fracturing technology.
The purpose of this utility model is to release a kind of liquid distributing pump vehicle of special use for oilfield, and it can satisfy the requirement of joining in the frac job for soup, and can substitute above-mentioned liquid truck.
This purpose can reach by the improvement to liquid truck:
Liquid distributing pump vehicle is the same with liquid truck, mainly comprises: an autotruck, be equipped with on its chassis: a cover driving device, its drive path is: automotive engine---power takeoff---transmission shaft---auxiliary gear box---solution feed pump; The full self-priming centrifugal pump of two parallel connections; A fluid storage tank; One cover can be finished and join the pipeline system that stirs the flow process and the flow process that directly supplies water for soup flow process, abundant widely different stream continuously, comprises sucking piping, escape piping and jet mixer (being proportioner); A maneuver control device.
Its improved part is: increased mechanical stirring device in fluid storage tank; Powder jar and dry powder drawing-in device on the medicine supplying pipe of jet mixer, have been increased; In maneuver control device, increased a ratio dosing gauge, it can show the proportioning of instant flow rate, total liquid volume and mixed liquor of weight, the water pump of medicinal powder, and regulate and control, thereby satisfy the requirement that accurately supplies vehicle.
Below in conjunction with drawings and Examples the utility model is done detailed description further.
Fig. 1 is the front elevational schematic of liquid distributing vehicle.
Fig. 2 is the schematic top plan view of liquid distributing vehicle.
Fig. 3 is the pipeline system and the path combination schematic diagram of liquid distributing vehicle.
Fig. 4 is a ratio dosing part scheme drawing in the liquid distributing vehicle.
Fig. 5 is a ratio dosing gauge functional-block diagram in the liquid distributing vehicle.
Referring to Fig. 1～Fig. 4.1 is autotruck among the figure.2 is the chassis of automobile, is equipped with on the chassis: (1) driving device 3, it comprises: power takeoff 3.1, transmission shaft 3.2 and auxiliary gear box 3.3.Centrifugal pump 10 runnings by two parallel connections of power driven of auxiliary gear box 3.3; (2) fluid storage tank 4, and two cover mechanical agitators 22 are housed in the case; (3) the powder jar 5, and totally two, in jar medicinal powder is housed, its underpart is provided with a dry powder feeding roller 15, and it is equivalent to the impeller of a rotation.With vacuum powder feeding pipe 16 is meal outlet and jet mixer 6(below the dry powder feeding roller 15 proportioner) medicine supplying pipe 24 join, be connected to a control cock 23 on the medicine supplying pipe 24, scalable is controlled into powder amount.In addition, in jet mixer, also increase a chemical agent charge pipe 28, can add other chemical agent from this pipe; (4), comprise sucking piping, escape piping and by-pass valve control that can finish and join continuously for the soup flow process, abundant widely different stream stirs flow process and direct water supply flow process, and is basic identical with liquid truck, no longer repeats with two pipeline systems that centrifugal pump 10 links.12 is outer induction pipe among the figure, and 11 is self-sucking device, and 9,13 for discharging pipe, and 7 is to the fluid storage tank exhaust tube, and 14 is the fluid storage tank induction pipe, and 18,19 is airtight suction valve, and 20,21 is airtight discharge-service valve; (5) maneuver control device 8, increase by one and can show the also ratio dosing gauge of scalable admixing medical solutions proportioning on the basis of liquid truck maneuver control device.
The type of drive of mechanical agitator 22 and dry powder feeding roller 15 is: drive power takeoff 3.1 by automotive engine, two of power takeoff drive a double-united oil pump job, double-united oil pump drives two groups of (totally 4) hydraulic motors 25 and 26 work, driving device mixer (two) and dry powder feeding roller (two) rotation again.Double-united oil pump comes the rotating speed of regulating control hydraulic motor by the hydraulic efficiency gear that comprises governor valve, change-over valve, to realize the adjusting of stirring rate and powder feeding flow.
Referring to 3,4,5.There is shown an embodiment of dosing gauge, the rotating speed of the dry powder feeding roller 15 of powder jar 5 bottoms is by electromagnetic sensor 31 output pulse signals of dosing gauge, through amplifying shaping 41 to gate circuit 51, oscillator 100 goes control gate circuit 51 to show accumulative total dry powder total weightes through counting machine 61, switch circuit 81 to counting machine 63 then through the 71 generation standard time of sampler simultaneously; The attached turbine flowmeter 17 of dosing gauge is contained in fluid storage tank exhaust tube 7, clear water liquid stream promotes its turbine rotation and makes electromagnetic sensor 32 output pulse signals, through amplifying shaping 42 to gate circuit 52, oscillator removes the gate circuit 52 of dominant discharge through 72 another standard time of generation of sampler simultaneously, one the tunnel remove to promote the cumulative volume of counting machine 64 in order to the accumulation output liquid through switch circuit 82 then, another road shows the instant flow rate of water pumps to decoding monitor 92; In addition, all send into divider 200, show the percentum of dry powder and clear water in the mixed liquors to decoding monitor 91 then from the two pulse signals that the counting machine 61,62 of dry powder metering roll and turbine flow comes out.
In addition, establish an adaptor union 27 in the bottom of powder jar 5 and also join, then can adopt the method for adjusting compressed-air actuated pressure to blow the loose powder material,, guarantee the smooth output of powder in case caking stops up with the compressed air system of pipe and automobile.
The advantage of liquid distributing pump vehicle is:
1, can satisfy the requirement of accurately joining in proportion in the fracturing technology for soup;
2, the percentage that can directly read soup from the dosing gauge is the medicinal powder cumulative weight when, the instantaneous delivery of total liquid volume and water pump;
