摘要： 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.
摘要翻译：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。

摘要： The present invention relates to synthetic hydrocarbons produced by skeletal isomerization, and the isomerization process. The products are especially useful as the continuous phase of a drilling fluid, for example when prepared from C14 to C18 linear alpha-olefins via isomerization or hydroisomerization, and as lube oils. The present invention also relates to a process for producing synthetic hydrocarbons by skeletally isomerizing C12+ olefins over a catalyst comprising an intermediate pore size molecular sieve, with or without Group VIII metals under skeletal isomerization conditions which result in little, preferably in subtantially no, olefin cracking or oligomerization.

摘要： A method for stabilizing argillaceous formations which are highly reactive in the presence of water. According to the method, the argillaceous formations are contacted with a solution comprising a polymer with hydrophilic and hydrophobic units. Said polymer can inhibit swelling and/or dispersion of the argillaceous rock due to its adsorptive and hydrophobic power. The use of said method in a drilling fluid is also described.

摘要： The use of high flash point, low vapor pressure compositions for injection into, and coating of, gas and oil wells and surrounding underground hydrocarbon bearing formations and processing equipment for the purpose of removing scale, paraffins, tars, and other viscous constituents. Treatment results in increased flow of gas and/or oil and decreased adhesion of soils and scale in all aspects of oil and gas recovery, including hydrocarbon bearing formations, casings, lines, and pumping equipment. The composition contains about 40 to 99 wt.% of a fatty acid alkyl ester blend and about 1 to 25 wt.% of at least one lower alkyl glycol ether.

摘要： Pulp residue waste is treated by reducing the water content below 7 % and is then milled in a ball mill and classified to remove particles of the inorganic filler greater than 1000 microns. When this material has a particle of the inorganic filler size below 20 microns, it can be used as a filler in plastics materials. When the particle size of the inorganic filler is between 50 microns and 1000 microns, it can be used as a lost circulation material in oil wells, where it gives excellent control of seepage or loss.
摘要翻译：通过将水分含量降低到7％以下进行处理，然后在球磨机中研磨并分级以除去大于1000微米的无机填料的颗粒。当该材料具有低于20微米的无机填料尺寸的颗粒时，它可以用作塑料材料中的填料。当无机填料的粒径在50微米到1000微米之间时，它可以用作油井中的流失物质，从而可以很好地控制渗漏或损失。
