DOLOMITIC POWDER
Dolomitic powder is a tonkodispersionny product, receive by mechanical crushing of dolomitic ore.
The offered new and traditional dolomitic weighting compound, consists of carbonate breeds and has the following chemical formula CaCO3MgCO3.
Density of dolomitic powder is equal to 2800 kg/m3 and possesses, will be dissolved by property, completely in hydrochloric acid. This advantage of dolomitic powder provides preservations of natural collection properties of a pay. As a result of it productivity oil and gassers increases. By means of dolomitic powder it is possible to prepare weighted drilling muds with a density of 1600 - 1700 kg/m3. Dolomitic powder is very well combined with chemical reagents and materials which are widely applied in practice of preparation of a drilling fluid. Thanks to it the drilling fluid prepared on the basis of dolomitic powder differs in the increased stability of technology properties. And it in turn warns the accidents and complications connected with deterioration in technology properties of the applied circulating drilling fluid.
