Special nanometer micro lotion water releasing and locking agent for oil field

一、performance

Low permeability reservoirs, due to their small pore throat diameter, have stronger capillary forces, resulting in a difference in magnitude compared to medium to high permeability reservoirs. In the process of mining operations, once external water enters the oil well under certain pressure, causing water lock pollution in the near wellbore area, it is difficult to recover through natural energy, resulting in low oil production and low liquid content, seriously affecting the economic development of the oilfield. This product is scientifically formulated from various surfactants and additives, with high oil water solubility and no interfacial tension between oil and water phases. By reducing capillary pressure and/or capillary end effect, it can effectively treat water invasion damage in the near wellbore zone of low-permeability reservoirs, and restore oil phase permeability to ≥ 90%. Has high salt tolerance, with a salt tolerance of over 20000mg/L. And it can also dissolve the gum asphalt precipitated near the wellbore, with a dissolution rate of over 20mg/L. It can effectively prevent and relieve water lock injuries, and protect oil and gas reservoirs.
