In drilling fluid additives, polyacrylamide is used as the drilling mud property adjusting agent whose function is to adjust rheological characteristic of drilling fluid, to carry rock fragments and tolubricate the drilling bit.

Besides,it can greatly reduce sticking accid ents, lighten equipment wear and tear and help regulate the hole diameter to avoid lost circulation and collapses.

Generally, it first undergoes primary oil recovery (primary recovery, exhausted mining, natural energy mining), then undergoes secondary oil recovery (secondary recovery, water injection development), and finally undergoes the so-called tertiary oil recovery (Tertiary recovery, physical and chemical thermal oil recovery, etc.).
Enhanced Oil Recovery technology (EOR for short) refers to the injection of oil repellents or profile control agents into the reservoir to improve the physical and chemical properties of the reservoir and reservoir fluids, and improve the macroscopic diffusion efficiency and micro-oil flooding efficiency of the oil recovery method, collectively referred to as improved oil recovery technology, or “Enhanced oil recovery technology to improve crude oil recovery is also called tertiary oil recovery (as opposed to primary oil recovery and secondary oil recovery).

Organic high efficiency cationic polymer solid and emulsion products, containing a variety of active groups, with turbidity removal, decolorization, adsorption, adhesion and other functions, its good water solubility, less consumption, stable performance, fast flocculation.
