<\/a>Drilling fluids have several important functions. They cool and lubricate the drill bit, stem and other down hole tools. The fluid also assists in sealing the sides of the bore, therefore stabilizing the borehole. Finally, drilling fluids are designed to carry the cuttings out of the hole. <\/span><\/p>\n The most widely used drilling fluids for HDD applications are bentonite, even if they are not so expensive compared with oilfield drilling fluids, but it is still a pollution for the environment, especially usually they dig a mud pit for HDD and pump the drilling fluids from the mud pit to shale shaker. After the directional boring<\/a>, how to treat the used drilling mud become a problem. <\/span><\/p>\n GN solids control can provide the complete solution for HDD fluids cleaning<\/a>, recycling and waste treatment. Firstly, during drilling, you should use an efficient HDD mud recycling system to clean and recycle the drilling fluids as much as you can. After drilling, the used mud together with the separated cuttings(separated from the 1st<\/sup> phase) will be collected by a storage tank, and enter into another waste management process. For the water based drilling fluids, we recommend GNZS853 hi-G dryer and decanter centrifuge GNLW363 centrifuge with a mud tank.After the primary process, the fluids with fine soils will be sent to water-treatment-plant for further cleaning, the solids will be transport by truck for cementing plant or construction application. <\/span><\/p>\n If you need a complete solution for HDD fluids system<\/a> for cleaning, recycling and waste treatment, pls contact GN solids control. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":" HDD means horizontal directional drilling or Directional boring, is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area.
