Drilling mud can be divided into two kinds of water-based mud and oil-based mud. During drilling and other work, to use the mud to cool the drill bit and remove the debris, the protection wall and balanced press. Bentonite dispersion, and the slurry volume, and therefore is an ideal material for drilling mud. My company developed in strict accordance with bentonite drilling mud Geology and Mineral Resources Ministry, the standard promulgated by the Ministry of Petroleum Industry and the American Petroleum Institute API OCMA standards and European standards of production, to complete the following number of mission-critical use in the drilling process: suspension, pressure control, rock stability, buoyancy, lubrication and cooling. Performance: good colloidal properties, the viscosity of the suspension increased sediment concentration is low, mud rate, low fluid loss, strong seepage capacity, high suspension, excellent lubricity and rheology. It has been put into geological drilling, oil drilling, horizontal crossing, subway tunneling field. I used to have a water-based mud bentonite DF-25, SM series. For white oil system has HFD-130D, 120, diesel system has HFGEL-40,130. National Free Shipping send free samples!
