FREE-FLOWING BOREHOLD SERVICING PREPARATIONS CONTAINING LINEAR ALPHA-OLEFINS, MORE PARTICULARLY CORRESPONDING DRILLING FLUIDS

摘要

THE INVENTION RELATES TO THE USE OF AT LEAST PREDOMINANTLY LINEAR HYDROCARBON COMPOUNDS OLEFINICALLY UNSATURATED IN THE ALPHA-POSITION WITH FLASHPOINTS OF AT LEAST ABOUT 80°C AS THE OIL PHASE OR AS PART OF THE OIL PHASE OF OIL- OR WATER-BASED FREE-FLOWING BOREHOLE SERVICING PREPARATIONS. PARTICULAR SIGNIFICANCE IS ATTRIBUTED TO CORRESPONDING DRILLING FLUIDS WHICH, TOGETHER WITH THE ALPHA-OLEFINS, CONTAIN IN OTHER OIL PHASES FROM THE FIELD OF BOREHOLE SERVICING PREPARATIONS AND ARE DISTINGUISHED BY ECOLOGICAL COMPATIBILITY, BEING DEGRADABLE UNDER BOTH AEROBIC AND ANAEROBIC CONDITIONS. SUITABLE MIXTURE COMPONENTS FOR THE OIL PHASE ARE, IN PARTICULAR, OLEOPHILIC ALCOHOLS, ETHERS AND CORRESPONDING ESTERS SELECTED FROM CARBOXYLIC ACID ESTERS AND/OR CARBONIC ACID ESTERS.
