1,Properties and applications
Low fluorescence blocking anti-collapse agent is made up of a variety of organic substances and it can be used directly into all kind of water-base drilling fluid. Mutual compatibility with asphalt, micro-cracks in a solid block wall, and adhesion in the wall to form a thin, tough filter cake, play a role in stabilizing wall. It has the characteristics of less increase, effective, non-foaming, not sticky and so on.
