Described a plurality of liquid adds that unit is arranged in parallel and be at least divided into two groups, each is organized liquid and adds and on the connecting line between unit, be equipped with three-way control valve door, two ends in described three-way control valve door connect respectively two groups of liquid and add unit, and all the other one end are connected with lotion unit by pipeline.In configuration fracturing fluid process, need the chemical addition agent kind of interpolation more, as: organic clay stabilizers, cleanup additive, bactericide, foaming agent, defoamer, demulsifier, fluid loss additive, pH adjusting agent, temperature stability agent, the broken glue activator of low temperature etc.According to chemical liquid compatibility principle, when some chemical addition agent mixes, can react simultaneously and cause additive to lose efficacy, therefore, at least 2 group liquid of described setting add unit and can add blending tank, also can add lotion manifold, by three-way diverter valve, change the input position that liquid adds.
Described mixed cell is blending tank, and its inside is provided with power agitating device, and liquid enters in blending tank at regular time and quantity according to automatic control and adjustment valve regulated, fully, after mix and blend, enters lotion unit.
Described lotion unit comprises lotion pump, flow sensor and automatic control and adjustment valve, and by pipeline, connects successively.Mixing material in blending tank and the liquid that directly enters lotion unit by three-way control valve door are realized lotion at regular time and quantity by lotion pump, flow sensor and automatic control and adjustment valve.
Preferably, described upper liquid pump, liquid add pump and lotion pump is self priming pump.
Preferably, described control module is PLC (programmable logic controller (PLC)), control liquid and add all power equipments in unit, mixed cell and lotion unit, comprise that liquid pump, liquid level sensor, flow sensor, automatic control and adjustment valve, liquid add pump and lotion pump, control liquid and add the online interpolation that unit carries out multiple additives, through different liquid, add unit and converge mutually at place, described lotion unit, through described lotion unit, supply with, discharge.
Described additive storage device is that liquid adds bucket or liquid adds car.
In sum, the beneficial effects of the utility model are: this device can solve that the flow that the on-the-spot artificial annex solution body additives of oil field compression fracture causes does not reach, the problem such as off quality, and this device can make plurality of liquid additive according to the difference of chemical compatibility, through different liquid, add unit and resupply, discharge after place, lotion unit converges mutually.
