MOBILE PLANT FOR MAKE-UP AND INJECTION OF PROCESS FLUIDS Russian patent published in 2015 - IPC F04B23/02 E21B43/12 

FIELD: oil and gas industry.

SUBSTANCE: plant comprises a frame, a tank, a pump unit, process unions, pipelines and stop valves. The tank consists of bottom settling zone with union to discharge mechanical impurities with volume of V₁ and top working capacity with volume of V₂, ratio of V₁ to V₂ is 0.65/4.35. The tank is equipped with fluid extraction pipeline. In the tank there is fluid return tube and fluid recirculation tube. The fluid extraction pipeline is horizontal and placed at the level of the bottom settling zone; it has the biggest diameter among all pipelines and tubes. The fluid return tube is vertical and descending from the top; it is placed in the centre of the tank and dead-ended from below; it is perforated in the bottom part; it has medium diameter in comparison with all pipelines and tubes. Fluid recirculation tube is parallel to fluid return tube; it is dead-ended from below and perforated along the whole height; it has the least diameter among all pipelines and tubes; dead-ended parts of tubes are placed above the bottom setting zone in the tank; the fluid extraction pipeline is equipped with stop valves allowing connection of the above pipeline with fluid recirculation tube, it is also equipped with filter screen. Oil production is intensified.

EFFECT: preventing scaling, asphaltene, resin and paraffin deposits; protecting downhole equipment from corrosion.
