Product details


Panlong Mountain@ HSR700 micronfine oil well cement is a basic of cement that is used for oil well cementing based on G grade, the average particle size isaround 7.4um (800 mesh). It’s the process of placing a solid andimpermeable material that supports and isolates the different well zones.ensuring well-integrity. As a grout, it has good permeability, strength anddurability properties.


  • Rapid-Setting Capabilities
  • Exceptional bonding and strength development.
  • Suitable for diverse wellbore cementing scenarios.
  • Reliable performance in oil and gas well construction.
  • Ensures secure and durable cement bonds.
