PF-SMARTSEAL:Intelligent Plugging Agent

Overview：

PF-SMARTSEAL  is an intelligent plugging agent of complex aluminum mixture. It is dissolved in high pH water-based drilling fluids and enters the formation with the filtrate. After contacting with the low pH liquid of the formation, it will produce precipitation, seal the micro pores of shale and reduce the pore pressure transmission rate, so as to stabilize the wellbore.

Characteristics：

Decrease permeability of rock matrix；Plug micro fractures of shale formations; Prevent pore pressure transmission rate；Enhance borehole stability.

Improve the efficiency of hard brittle shale film, used for shale collapse prevention, high pH water base system (wide temperature)"

PF-GREENSEAL: Environmental protection sealing  agent

Overview：

PF-GREENSEAL sealing agent is a kind of nano-scale deformable polymer for sealing micro fractures and pores in shale. It is a gray solid powder and is soluble in water. It can effectively seal micro fractures, improve the pressure bearing capacity of the wellbore and reduce differential pressure sticking.

Characteristics：

Nano-scale deformable plugging polymer; Reduce pore pressure transmission rate; Reduce pressure differential sticking.

Special blocking agent for broad-spectrum environmental protection drilling fluid-BIODRILL A , temperature: ≤180℃.

PF-EPF  L: Emulsified paraffin ( Liquid )

Overview：

PF-EPF L is a kind of paraffin nanoemulsion. Due to its small particle size, it can enter the micro-fractures of shale formation, reduce the penetration of filtrate into the formation, reduce the velocity of pore pressure transmission, and enhance wellbore stability.

Characteristics：

Reduce pore pressure transmission rate;  Stabilize wellbore; Environmentally friendly.

Micron emulsified paraffin, used for shale sealing and collapse prevention, temperature: ≤180℃.

PF-NSEAL: Nano latex sealing agent

Overview：

PF-NSEAL is a kind of nanoscale deformable polymer latex. Applied to water-based drilling fluid, it can plug the nano-scale pores and micro-fractures of shale, and effectively reduce the pore pressure transfer rate of drilling fluid in shale; It has a synergistic effect with other   micro-scale plugging agents, which can further reduce the filtration , enhance the toughness of the mud cake, minimize the differential pressure sticking, and improve the stability of the wellbore.

Characteristics：

Nano-scale particles, which can effectively seal micro-pores; Salt and temperature resistance, little impact on drilling fluid rheology; Low cost.

Nano-emulsion sealing agent, improve the membrane efficiency of hard brittle shale, used for shale collapse prevention,  temperature: ≤180℃. "
