Nano microemulsion dialyzer for oilfield fracturing fluid

1、performance

Tight/shale reservoirs have ultra-low permeability, ultra small pore throat radius, and extremely low porosity, making it difficult for crude oil in the reservoir to flow and unable to be extracted. Hydraulic fracturing can form complex fracture networks in reservoirs, where artificial and natural fractures communicate with each other, providing flow channels for crude oil and achieving commercial exploitation of tight/shale oil. Therefore, fracturing is a commonly used stimulation measure for reservoir transformation. So far, the main purpose of all fracturing operations is to open a crack in the reservoir, then fill it with proppant, and form an artificial high permeability channel in the formation. As the fracturing fluid flows back, the entire fracturing process ends. The effectiveness of fracturing is evaluated based on the production of the fractured well after it is put into operation. However, the remaining fracturing fluid in the formation is believed to have a negative impact on the fracturing effect. Therefore, after fracturing, it is required that the fracturing fluid be returned as soon as possible to reduce the damage caused by the presence of fracturing fluid to the formation, resulting in low oil well production and poor fracturing effect. This product is scientifically formulated from various surfactants and additives, with a particle size of less than 100nm. It has ultra-low interfacial tension and high solubilization ability. Due to the small particle size, oil wetness, and low surface tension of micelles, compared with conventional surfactants, the reservoir has a smaller adsorption capacity for them. When used in combination with fracturing fluid, it can not only eliminate the damage caused by the retention of fracturing fluid in the formation, but also play a role in oil displacement, changing the single function of fracturing fluid, improving the effect of fracturing process, and turning disadvantages into advantages, This has greatly improved and ensured the effectiveness of the well after fracturing.
