This product is formed by the degradation of polyacrylonitrile under high temperature and pressure. Its main components contain carboxylic acid, carboxyl groups, amide groups and imine groups, etc., and its particles are not easy to clump. This product has a strong effect of reducing drilling fluid filtration loss and high temperature and high pressure filtration loss, strong temperature resistance, good thermal stability, etc. It has a certain ability to inhibit clay hydration and prevent collapse, and also has good salt resistance and pollution resistance. It can be directly applied to various water-based drilling fluid systems as a filtration loss reducer and anti-collapse agent, and can be used in combination with various treatment agents.

Low dosage, high mud-making rate; good salt resistance, strong antibacterial properties, easy to use; good filtration loss reduction and thickening effect; strong rheological control and suspension ability; the product is green and environmentally friendly, non-toxic, harmless and odorless; the product has good fluidity and convenient construction, etc. (3. Name): Sulfomethylphenolic resin (SMP) Introduction: Sulfomethylphenolic resin can gently lubricate and cool the drill bit in drilling fluid, lubricate and dissipate heat, support the well wall, control drilling fluid pressure and reduce leakage. At the same time, it can effectively reduce filtration loss and has the functions of high temperature and salt resistance. It is suitable for deep and ultra-deep well drilling, has a lower viscosity effect, and is more suitable for use in high-density drilling fluids.

It is suitable for deep and ultra-deep well drilling, has a lower viscosity effect, and is more suitable for use in high-density drilling fluids.

It plays a role in lubrication and reducing high temperature and high pressure filtration loss in drilling fluid; it is a multi-functional organic drilling fluid treatment agent with functions such as plugging leakage, preventing collapse, lubrication, drag reduction, and inhibition; it lubricates and reduces drag, reduces the lifting capacity and torque of the drill string, prevents and releases stuck drill bit, and forms a thin and tough mud cake to strengthen the well wall; it controls high temperature water loss and controls the high temperature shear strength of the mud. It can be used in combination with other mud treatment agents.

A drilling fluid thickener with strong temperature resistance, usable at temperatures up to 180℃, stable performance, and characterized by low content, high thickening, and high suspension; it also has excellent fluid loss reduction properties, uniform solubility, and good thickening, salt resistance, and anti-fouling properties; it is easy to prepare, maintain, and handle on-site, and will not cause solid phase damage to the reservoir when used to prepare solid-free drilling fluids; drilling fluid thickeners offer a single material, low cost, and better economic benefits.

This product is a modified product of lignite, a natural macromolecular organic compound, with good filtration loss reduction effect and high temperature resistance, making it an excellent high-temperature and high-pressure filtration loss reducer. Lignite resin plays an important role in drilling fluids, including reducing filtration loss, stabilizing drilling fluid properties, resisting temperature, salt, and pollution, and inhibiting formation hydration swelling.
