1. Product introduction
This product is made of natural plant polymer materials of different types, shapes and sizes through special processes. It has fast plugging speed and good effect on pores and micro fractures, and can quickly form an impermeable shielding belt with certain strength to prevent solid and liquid from invading the formation and play a role in reservoir protection.
It is applicable to various water-based and oil-based drilling fluid systems. It is easy to use, has good compatibility, does not affect the performance of drilling fluid, and can also reduce the filtration of drilling fluid. It is non-toxic and beneficial to environmental protection.
