AU-33 Wetting Reversal Agent

Oil gas wells operating in the process, as a result of fluid added in the near wellbore formation into a strong easy to oily wet, thereby reducing the permeability of oil phase to increase the permeability of water phase, the water saturation increases, tests show If the water saturation from 20% to 35%, the oil relative permeability from 90% to 30%, to ground into a strong low interfacial tension of the hydrophilic surfactant, wetting by the oil stratum can change fwater wetting, thereby increasing penetration of the oil phase; low interfacial tension of high viscosity of crude oil can flow help reduce the permeability of water phase, reducing the space occupied by the flow volume (ie, saturation), the lifting of formation water lock effect, so that oil production increases.

Specification:
(1) Appearance: colorless pale yellow liquid;
(2) Density: 0.95 ~ 1.05g/cm³;
(3) Temperature: ≤ 150 ℃;
(4) Surface Tension: ≤ 28mN / m;
(5) interfacial tension: ≤ 0.6mN / m
(6) wetting angle (contact): ≤ 45.

The principle of wellion:
AU-33 wetting agent is mainly used to reverse the low-permeability oil gas well construction operations.

Usage:
In construction operations, into the well fluid can also be added before the flushing fluid liquid such as sand-carrying liquid into the well to add, can also be added after the liquid into the well, the general use of the concentration of 6%.
