PCT No. PCT/EP95/02143 Sec. 371 Date Dec. 13, 1996 Sec. 102(e) Date Dec. 13, 1996 PCT Filed Jun. 6, 1995 PCT Pub. No. WO95/34610 PCT Pub. Date Dec. 21, 1995The 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 DEG 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 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.
