    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: 这里描述了一种应用于钻探设备的新型液压流体组合物。 这些液压流体组合物允许在陆地或近海钻井期间有效监测或控制井的井口压力。 当施加到钻井设备上时,液压流体组合物在钻井或提取过程期间防止气体,油或另一井流体从地下地层中不受控制地流出。 因此,提供了一种液压流体浓缩物,其含有水溶性磷酸酯和含有至少一个S-S键,至少10个碳原子和至少一个末端羧酸酯基的硫化物化合物,其中S-S键连接两个烷基。 其他组分可以加入到浓缩物中,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,倾点抑制剂和水,乙二醇或 它们的组合。 如此处所述,浓缩物然后被消费者进一步稀释使用。 特别地,这些组合物有效减少与液压流体组合物接触的金属的海水腐蚀,减少与液压流体组合物接触的石油钻探设备中的生物累积,并且对海洋生物具有低毒性。
