Pumping unit polish rod sealing lubricating grease and preparation method thereof

The invention belongs to the technical field of oil field lubrication, and particularly relates to pumping unit polish rod sealing lubricating grease and a preparation method thereof. The pumping unit polish rod sealing lubricating grease acts on a sealing part of a pumping unit wellhead polish rod packing, so that the pumping unit polish rod packing can be well sealed, and leakage is prevented; in addition, the oil pumping unit polish rod can be well protected, and the risk of rusting of the oil pumping rod is reduced. And the packing has good compatibility with packing rubber, so that the service life of the packing can be effectively prolonged. The pumping unit polish rod sealing lubricating grease specifically comprises the following components: base oil, base grease, a sealing reinforcing agent, a friction improver and a rubber compatibility improver. 本发明属于油田润滑技术领域，尤其涉及一种抽油机光杆密封润滑脂及其制备方法。该种抽油机光杆密封润滑脂作用于抽油机井口光杆盘根密封部位，可以很好的起到密封抽油机光杆盘根的作用，防止泄漏发生；此外，还可以对抽油机光杆起到良好的防护作用，减小抽油杆生锈的风险；以及对盘根橡胶具有良好的相容性，从而可以有效的延长盘根的使
