    • Described is the use of oleophilic esters of ecologically compatible polycarboxylic acids with oil-soluble and ecologically compatible monofunctional alcohols and/or polyfunctional alcohols which may also be watersoluble as the oil phase or as a component of the oil phase of oil-based or water-based drilling fluids and other fluid drill-hole treatment agents. The oleophilic polycarboxylic acid esters are especially suitable as component of the continuous oil phase of inverted fluids of the W/O type. Here--if rheologically suitable compounds will be employed--they may comprise the at least predominant portion of the continuous oil phase; but also possible is the concomitant use of complex oleophilic polycarboxylic acid esters, which are not or just to a restricted degree fluid in a temperature range of from 0.degree. C. to 20.degree. C., as an additive in fluid oils of the class of the non-polluting oils. Here, suitable oil mixing phases especially are oleophilic alcohols, ethers, respective esters of monocarboxylic acids and fluid oils based on oleophilic carbonic acid diesters.
    • 描述了生态相容的多元羧酸的亲油酯与油溶性和生态相容的单官能醇和/或多官能醇的使用,它们也可以作为油相或作为油相或水溶性油相的油相的组分, 基础钻井液和其他流体钻孔处理剂。 亲油性多羧酸酯特别适合作为W / O型倒置流体的连续油相的组分。 在这里 - 如果使用流变学合适的化合物 - 它们可以包括连续油相的至少主要部分; 但是也可能伴随使用复杂的亲油性多元羧酸酯,它们在0℃至20℃的温度范围内不是或仅限于限制流体,作为该类流体油中的添加剂 无污染的油。 这里,合适的油混合阶段尤其是亲油醇,醚,单羧酸的各自的酯和基于亲油碳酸二酯的流体油。

    • Compositions free from mineral oil and used for freeing jammed drill pipes in drilling operations, and processes for using such compositions are disclosed. The compositions comprise a mixture of:(a) one or more fatty acid alkyl esters corresponding to the following general formula ##STR1## in which R.sup.1 is a linear C.sub.7 -C.sub.23 alkyl, alkenyl or alkadienyl radical andR.sup.2 is a linear or branched C.sub.1 -C.sub.8 alkyl or hydroxyalkylene radical,(b) one or more thickeners such as organophilic bentonites, and(c) one or more emulsifiers.Preferred emulsifiers include a mixture of an aminoamide or a polyamine and a fatty acid or calcium salt thereof. The composition may contain other conventional additives and is adapted to be formulated in the field by blending with water and/or weighting agents to achieve the proper thickness and density for use as a well spotting fluid.
