Abstract

The invention relates to the use of at least predom-inantly linear hydrocarbon compounds olefinically un-saturated 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. It also relates to a drilling fluid composition comprising an auxillary fluid compris-ing such linear hydrocarbon compounds olefinically unsaturated in the alpha-position and to processes for sinking a bore in a rock. Particular significance is attributed to corresponding drilling fluids which, together with the alpha-olefins, contain other oil phases from the field of borehole servicing preparations and are distinguished by ecological compatibility, being degrad-able 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.
