Description

一种严寒区抽油机用润滑油
技术领域
本发明涉及润滑油技术领域，具体涉及一种严寒区抽油机用滑油。
背景技术
抽油机是石油开采中常用的采油设备，广泛应用于油田采油作业中，传统的抽油机采用游梁式曲柄平衡抽油机（俗称：磕头机）。近年来由于节能及环保的原因，油田采油作业广泛采用立式抽油机。立式抽油机用润滑油要兼顾齿轮润滑和液压系统传递能量的介质，同时起到润滑、冷却、密封的功能。由于抽油机属于野外工作设备，其工作环境温度变化非常大，所以要求抽油机用润滑油必须具有适宜的粘度、良好的粘温性能、抗磨抗氧性能，才能为抽油机提供足够的抗磨损性能和润滑性能，确保抽油机连续平稳的工作。特别是在严寒地区（-40℃）为确保抽油机的正常运行，要求抽油机用润滑油必须具有卓越的低温流动性，从而确保抽油机的正产润滑，保护设备正常运转。
发明内容
本发明的目的在于提供一种严寒区抽油机用润滑油，具有良好的低温流动性、粘度、粘温性能、抗磨抗氧性能。
为了达到上述的目的，本发明提供了如下技术方案：
一种严寒区抽油机用润滑油，包括如下重量份的组分：基础油80-95份、降凝剂0.5-1.5份、增粘剂5-15份、抗氧剂0.1-2份、极压剂3-5份、抗磨剂0.5-3份、油性剂1-3份、防锈剂0.02-0.8份、消泡剂5-10ppm。
进一步的，所述基础油为Ⅲ类加氢合成基础油A、Ⅲ类加氢合成基础油B、Ⅲ类加氢合成基础油C和Ⅳ类聚α烯烃基础油D中的至少两种。
本发明基础油为至少两种不同类型的基础油复合而成，能与其他添加剂呈现良好的协同效应，尤其是与降凝剂协同复配，能够提高润滑油的低温流动性、粘温性能、抗磨抗氧性能。
进一步的，所述Ⅲ类加氢合成基础油A为40℃粘度18-22mm2 /s，粘度指数≥110，闪点不低于215℃。
进一步的，所述Ⅲ类加氢合成基础油B为40℃粘度46-55mm2 /s，粘度指数≥110，闪点不低于230℃。
进一步的，所述Ⅲ类加氢合成基础油C为40℃粘度416-475mm2 /s，粘度指数≥90，闪点不低于250℃。
进一步的，所述Ⅳ类聚α烯烃基础油D为100℃粘度4-6mm2 /s，粘度指数≥130，闪点不低于230℃。
本发明通过基础油进行加氢处理，提高了基础油品质，降低了润滑油的凝点，可以提高润滑油的耐低温性能。
进一步的，所述降凝剂为聚α烯烃T803B或聚甲基丙烯酸酯T602；所述增粘剂为聚甲基丙烯酸酯T602、乙丙共聚物0010和乙丙共聚物0050中的至少一种。
进一步的，所述抗氧剂为2，6二叔丁基对甲酚T501；所述极压剂为硫化异丁烯T321；所述抗磨剂为硫磷酸双含氮衍生物T305、硫代磷酸复酯胺盐T307中的至少一种。
进一步的，所述油性剂为硫化棉籽油T404、硫化烯烃棉籽油T405中的至少一种；所述防锈剂为十二烯基丁二酸T746、烯基丁二酸半酯Irgacor L 12和异壬基苯氧基乙酸Irgacor NPA中的至少一种。防锈剂可优先吸附于金属表面或与表面发生化学反应生成保护膜，抑制氧及水和金属接触，起到防锈作用。
进一步的，所述消泡剂为甲基硅油T901、甲基硅油酯T903中的至少一种。
本发明所提供的一种严寒区抽油机用润滑油，相比于现有技术具有如下有益效果：
本发明通过不同粘度的基础油与降凝剂、增粘剂、抗氧剂、极压剂、抗磨剂、油性剂、防锈剂和消泡剂复配，制备的润滑油具有优异的抗氧化性、粘温性、低温流动性以及优良的剪切稳定性、抗磨性和修复功能，改善了润滑油综合性能、提升了润滑油的品质，提高抽油机寿命，为石油的开采提供更大的助力，尤其提高严寒地区的石油开采。
