    Abstract: The present invention provides: an oil agent additive that is easily soluble in an oil agent and is outstandingly effective in reducing the friction coefficient; and an oil agent composition that contains the oil agent additive. This oil agent additive contains at least one compound represented by a Chemical Formula (1). (In the formula: R1 and R2 are each an aliphatic hydrocarbon group with a carbon number of 1-33; the total carbon number of R1 and R2 is 2-34; X is a single bond or an aliphatic hydrocarbon group with a carbon number of 1-5; and A is —O—CH2—CH(OH)—CH2OH or —O—CH(—CH2—OH)2.)

    Abstract: A novel hydraulic fluid composition for application to drilling equipment is described herein. These hydraulic fluid compositions permit effective monitoring or controlling well-head pressure of a well during drilling on land or offshore. The hydraulic fluid compositions prevent uncontrolled flow of gas, oil, or another well fluid out of an underground formation during a drilling or extraction process when applied to the drilling equipment. Accordingly, provided is a hydraulic fluid concentrate which contains a water-soluble phosphate ester and a sulfide compound containing at least one S—S linkage, at least 10 carbon atoms and at least one terminal carboxylate group, wherein the S—S linkage bridges two alkyl groups. Additional components can be added to the concentrate and include one or more alkaline compound, one or more dicarboxylic acid or salt thereof, a water-soluble corrosion inhibitor, a water-soluble biocide, a pour point depressant, and water, ethylene glycol, or a combination thereof. The concentrate is then further diluted by the customer for use as described herein. Particularly, these compositions are effective in reducing seawater corrosion of a metal in contact with the hydraulic fluid composition, reducing bioaccumulation in oil drilling equipment contacted with the hydraulic fluid composition, and have low toxicity to sea life.

    Abstract translation: 本文描述了一种应用于钻井设备的新型液压油组合物。 这些液压流体组合物允许在陆地或海上钻井期间有效监测或控制井的井头压力。 液压流体组合物在施加到钻井设备时在钻井或提取过程期间防止气体，油或另一井井液流出地下地层的不受控制的流动。 因此，提供了含有水溶性磷酸酯和含有至少一个至少10个碳原子和至少一个末端羧酸酯基团的至少一个S-S键的硫化合物的液压流体浓缩物，其中S-S键连接两个 烷基。 可以向浓缩物中加入另外的组分，包括一种或多种碱性化合物，一种或多种二羧酸或其盐，水溶性缓蚀剂，水溶性杀生物剂，倾点降低剂和水，乙二醇或 其组合。 然后，如本文所述，浓缩物被客户进一步稀释使用。 特别地，这些组合物有效地减少与液压组合物接触的金属的海水腐蚀，减少与液压组合物接触的石油钻井设备中的生物累积性，并且对海洋生命具有低毒性。
