PRODUCT DESCRIPTION

In the process of oil and gas wells operating, it is easy to inject the work fluid to change the near wellbore formation into oily wet.Thereby reducing the permeability of oil phase to increase the permeability of water phase, the water saturation increases. If the water saturation increase from 20% to 35%, the oil relative permeability decrease from 90% to 30%, inject a strong low interfacial tension of the hydrophilic surfactant to ground, wetting by the oil stratum can change for water 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 (i.e., saturation), the lifting of formation water lock effect, so that oil production increases. The wetting reversal agent is mainly used to reverse the low-permeability oil and gas well construction operations. By utilizing the reverse wetting agent, the surface tension of an engineering residual liquid is reduced, the interface tension is reduced, the tubular billet resistance is reduced, the adhesive power of the engineering residual liquid when flowing in a reservoir is reduced, and the oil wetting in oil reservoir rock is reverted into water wetting, so that the water blocking is canceled so that a working liquid can flow back.

APPLICATION METHOD

In construction operations, the product can be added before the flushing fluid or 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%
