Creation of Favourable Water - Physical Properties of Drill Cuttings with the use of Coagulants

The negative physical properties of drilling cuttings are caused generally by the presence of large amounts of exchangeable sodium. Its sources are boring solutions with the use of caustic and soda ash and also the saline rocks extracted in the process of drilling. Drilling cuttings have lack of structure and swelling in the wet state, adhesiveness, low water mobility, reduced air exchange, a high hydrophylicity, lack of filtration capacity. In addition to these physical properties drilling cuttings are characterized by a number of the negative chemical properties, in particular, a high alkalinity and the presence of easily soluble toxic salts of sodium, the lack of exchangeable calcium and magnesium. The following properties make absolutely impossible the use of drilling cuttings in road construction, and also taking into acoount their restoration. Application of a number of natural coagulants such as (gypsum, diatomite, quicklime, etc.) And the waste of the industrial activity (a phosphogypsum, carnallite, sludge formed during the purification of the surface and underground water) radically improves physical properties of drilling sludge and provides multiple increase in filtration capacity.
