| titleOfInvention | Oleophilic alcohols for use as a component of invert drilling-oil muds |
| abstract | Use as a closed oily phase of drilling muds one of the following two constituents: (a) monovalent and / or polyvalent alcohols of natural or synthetic origin, at least largely insoluble in water and flowing and pumpable in the temperature range from 0 to 5 ° C; or (b) solutions, flowable and pumpable in the temperature range indicated above, of monovalent and / or polyvalent alcohols of natural and / or synthetic origin at least largely insoluble in water in oils not pollutants insoluble in water. These drilling muds are in the form of emulsions of oil in water, they comprise, in the oily phase containing alcohols, a dispersed aqueous phase as well as, if necessary, other usual additives and can be used for ecological exploitation of petroleum or natural gas, for example. The invention further relates to drilling muds of the type described above, which are characterized in that they additionally contain, as a closed oily phase or in dissolved form in oils insoluble in water, d '' other monovalent and / or polyvalent alcohols at least largely insoluble in water, the corresponding oily phase being flowing and pumpable in the temperature range from 0 to 5 ° C and its flash point being higher than 80 ° C . |
