The proposal relates to the oil and gas industry, in particular to mobile oilfield mixing installations.

Known mobile oil pump unit SYN-35, manufactured gas engineering "synergy" (Perm), and similar mobile oil pump unit type UNB according to GOST 28922-91, in which mixing is prepared in a volumetric tank mixture is produced by pumping the pump, with the selection of the mixture from the bottom of the measuring tank, and reverse pumping the mixture from the upper open side of the measuring tank. A disadvantage of the known mobile oilfield pumping units is the fact that mixing is prepared in a volumetric tank mixture not intensive enough. When mixing viscous mixtures, such as oil-water emulsions or aqueous solution of hydrolyzed polyacrylonitrile, a measuring tank remain stagnant zones. That is, using only the hydrodynamic mixing in some cases unable to properly mix the prepared mixture.

Known installation for the preparation of solutions containing mounted on the chassis of the vehicle tank with agitators, hydraulic vacuum mixer and pipelines [RF patent №62860, IPC VS 5/38 published 10.05.2007, bull. No. 13]. Installing Borodulina sand pump, connected with the tank and hydraulic vacuum mixer in a closed system, and the capacity for chemicals to which to heat summed up the exhaust gases from the engine of the vehicle. The disadvantage of installation is that the capacity for chemical reagents is heated by exhaust gases from the vehicle engine, the temperature of the internal combustion engine reaches 700°C. Such a high temperature may adversely affect the properties used for the preparation of solutions of chemical reagents.

The closest technical solution to the present invention is a mixing device for preparation of solutions [RF patent №2179928, IPC VS 9/02, publ. 27.02.2002]. The mixing system includes a vehicle with included in its composition the compressor and the receiver placed on the reservoir for the liquid, divided in half, with the shut-off bodies and measure volume in each half, the pump receiving portion through which the piping and valve bodies connected with a reservoir for liquid aerating device that communicates with a receiver of the compressor of the vehicle air duct through the valve. The disadvantage of mixing plant is the complexity of its construction, as well as the lack of heating of prepared rest the ditch.

The technical objective of the proposals is the creation of a mixer with a simple design that provide heating and obtaining a more homogeneous mixture of the reactants over a shorter time interval due to ozonation supplied by the turbocharger preheated air.

The problem is solved, we offer mobile oilfield mixing installation comprising a vehicle from entering into its composition the receiver and the compressor is placed on the reservoir for the liquid, divided in half, with the shut-off bodies and measure volume in each half, the pump receiving portion through which the piping and valve bodies connected with a reservoir for liquid aerating device in communication with the compressor of the vehicle.

What's new is that the exhaust system of a vehicle equipped with a turbocharger, which through insulated duct through the valve communicates with the aerating device, while the upper point of the duct aerating device is located above the top of the tank for the liquid, and aerating device is simultaneously heat pipe to heat the prepared mixtures of reagents and made in the form of a coil, with holes for air outlet.

Research the Pat is based and scientific-technical literature showed this set of essential features is new and not previously used, and this, in turn, allows to make a conclusion about the technical solutions according to the criterion of "novelty".

In figure 1 (side view) and figure 2 (top view) shows the mobile oilfield mixing plant. In addition to new features, design mobile oilfield mixing plants such well-known design mobile oilfield pumping units of the type UNB according to GOST 28922-91, for example, SHIN-35 or CA-320. Mobile oil mixing system includes a vehicle 1 with its composition by the receiver 2 and the compressor (Fig. not shown), placed on the reservoir for the liquid 3, divided in half, with a locking bodies 4 and the measuring volume in each half (Fig. not shown), and pump 5. Receiving portion of the pump 5 by means of the manifold valve (Fig. not shown), and valve bodies 4 is communicated with a reservoir for the liquid 3. The discharge side of the pump 5 through the pipeline (Fig. not shown) with the valves 6 and 7 are connected by pipes 8 and 9 for hydrodynamic mixing and conveying fluid in any half of the reservoir for the liquid 3. Mobile oil mixing plant at the bottom of the tank liquid is 3 equipped with aerating device 10, having a body in the form of coil 11 and the holes 12 for the escape of air. Exhaust system the vehicle is equipped with a turbocharger 13, through which insulated duct 14 through the valve 15 communicates with the aerating device 10, with the top point insulated duct 14 is located above the top of the reservoir for the liquid 3. The duct 14 teploizolirovat from its highest point to the turbocharger 13 in any known manner, for example using a cylinder of insulating mineral wool with synthetic binder on THE 5762-010-45757203-01. The receiver 2 of a vehicle air duct 16 through the valve 17 is communicated with a heat-insulated duct 14. The installation position of the turbocharger 13 and receiver 2 in the figure shows the relative and depends on the design features of the vehicle.

Mobile oil mixing device operates as follows. In the reservoir for the liquid 3 pump 5 pump the reagents in the mixture. For mixing of reagents open the shut-off bodies 4 and the pump 5 are selected mixture of reagents from the bottom of the reservoir for the liquid 3, then through the pipes 8 and 9 serves a mixture of reagents in the upper part of the reservoir for the liquid 3. Thus, hydrodynamics the first stirring of preparing a mixture of reagents. The process of hydrodynamic mixing of prepared mix reagents to offer mobile oilfield mixing setup similar to the same process, implemented on a mobile oilfield pumping units well-known style design UNB according to GOST 28922-91, for example, SHIN-35 or CA-320. In the process of hydrodynamic mixing driven by the exhaust gases of the engine turbocharger 13 insulated duct 14 submit to the aerating device 10 air under pressure. When the valve 15 is open and the valve 17 is closed. Extending through the openings 12, the air carries away the threads of prepared mix reagents and provides additional mixing. When the turbocharger 13 is heated excess air due to compression. Therefore, if additional mixing is a simultaneous heating of prepared mix reagents due to heat transfer from the heated air corps 11 aerating device 10 and by direct heating of the air, bubbling fluidised bed through a mixture of reagents. As a vehicle for the proposed mobile oilfield mixing plant can be used KrAZ-65053 with the engine JAMZ-D, which is often used as a vehicle the La mobile oilfield pumping units of the type UNB according to GOST 28922-91. The exhaust system of the engine YAMZ-D can be equipped with a turbocharger TRC-12, produced by LLC "Melitopol factory turbochargers, which leads to heating the charge air to a temperature of 100-150°C. if the need for heating the prepared mix reagents no override valve 15 and stop the flow of heated air by the turbocharger 13. This open valve 17 and served in the air from a compressor (Fig. not shown) through the receiver 2 and the ducts 16 and 14 in the aerating device 10. In this case produce additional stirring bubbling fluidised bed through a prepared mixture of reagents, the air supplied by the compressor (Fig. not shown). The top point insulated duct 14 is located above the top of the reservoir for the liquid 3, which ensures the impossibility of getting prepared mix of reagents in the compressor 2 or turbocharger 13. Even in the absence of air supply ducts 16 and 14 prigotavlivaemy mixture of reagents cannot climb insulated duct 14 above the top of the reservoir for the liquid 3. After mixing of the reagents and pumping it out of the reservoir for the liquid 3, the ducts 16 and 14 are blown off with air to remove residual reagents.

Fill the nutrient stirring bubbling fluidised bed air increases the intensity of mixing, allows you to cook more homogeneous mixture of the reactants over a shorter time interval. To increase the intensity of stirring bubbling fluidised bed air vehicle may be equipped with two turbochargers. Unlike the prototype, additional agitation bubbling fluidised bed air does not provide for the use of additional mixing devices having moving parts, which reduces the probability of failure with increasing effectiveness of the proposed integrated mobile oilfield mixing plant. The availability of heating allows in the winter time to prepare a mixture of reagents, increasing the viscosity of which at low temperature makes them not pumped by the pump. When heating the reagents in most cases, their viscosity decreases, which allows the same equipment to produce a more intense mixing.

The totality of the claimed features ensures the achievement of the technical result - the creation of a mixer with a simple design that provide heating and obtaining a more homogeneous mixture of the reactants over a shorter time interval due to ozonation supplied by the turbocharger preheated air.
