Product Brief
CQY-7 Sweeping Agent is a special treated 100% virgin synthetic monofilament fiber that is used as a hole clean agent. When mixed in various fluids, Sweeping agent enhance the carrying capability of drilling fluids without increasing viscosity of the fluids. CQY-7 sweeping agent is non-corrosive, non-magnetic, chemically inert, and temperature stable in the designed application.
For the purpose of hole cleaning, CQY-7 is added to various drilling fluids to increase the flow and removal of solids & cuttings out of the well by forming a uniform and disorderly supporting system.
