    • A non-polluting additive or spotting fluid which lubricates, releases and/or prevents differentially stuck drill strings and casings in the wellbore of a subterranean well is presented. This additive composition comprises a glycol or glycol ether derived from a long chain epoxide of greater than 3 carbon atoms (preferably greater than 10 carbon atoms); and preferably comprises the reaction product between 2-ethylhexanol and the epoxide of 1-hexadecene. The present invention enhances the lubricity of a drilling fluid to prevent drill string sticking and when utilized as a spotting agent reduces the time required to release a stuck pipe. This invention also helps reduce or prevent foaming. By eliminating the need for traditional oil-based components, the present invention is non-toxic to marine life, biodegradable, environmentally acceptable, easy to prepare, and capable of being disposed of at the drill site without costly disposal procedures.
    • 提出了一种在地下井的井眼中润滑,释放和/或防止差异卡钻钻柱和壳体的无污染添加剂或点样液。 该添加剂组合物包含衍生自大于3个碳原子(优选大于10个碳原子)的长链环氧化物的二醇或二醇醚; 并且优选包含2-乙基己醇与1-十六碳烯的环氧化物之间的反应产物。 本发明提高了钻井液的润滑性以防止钻柱粘附,并且当用作点样剂时,减少了释放卡住管所需的时间。 本发明还有助于减少或防止起泡。 通过不需要传统的油基成分,本发明对海洋生物无毒性,可生物降解,环境可接受,易于制备,并且能够在钻孔位置处理而无需昂贵的处理程序。
