Abstract

The invention relates to ultrahigh-temperature-resistant composite multi-soap-base self-restored bearing lubricating grease and a preparation method thereof. The lubricating grease is prepared by mixing composite synthetic base liquid, a composite thickening agent, a high temperature antioxidant additive, an anticorrosive metal passivation agent, an inertia extreme-pressure additive, a self-restoration additive and a structural modifier. On the basis of the patents ZL200510120518.X and ZL201210033794.2, the base liquid, the thickening agent, the extreme-pressure additive, an anti-abraison additive and the like are optimized, the obtained lubricating grease not only can satisfy the extreme pressure, high temperature, abrasion resistant, self-restored lubrication requirements of a roller bit bearing, but also can keep the performance of product unchanged in an environment with the temperature higher than 200 DEG C, is capable of preventing the failure of the bit bearing, is particularly suitable for being used in the roller bit bearing of geothermal wells and deep stratums in the petroleum geographic exploitation field and has important significance on enlarging the application temperature range of the roller bit bearing.

Description

technical field [0001] The invention relates to an ultra-high temperature resistant composite multi-soap based self-repairing bearing grease and a preparation method thereof, in particular to a composite multi-soap-based self-repairing bearing grease used in petroleum geological exploration, drilling, geothermal, deep well, and high-temperature field roller cone bits and its preparation method. Background technique [0002] With the continuous development of shale gas and geothermal deep well high-temperature oil and gas exploration, the industry's requirements for the high-temperature resistance of exploration drilling tools have also been continuously improved. requirements are also more stringent. [0003] Oil roller cone bits used in petroleum geological exploration drilling, the drill bit bearings are faced with extremely high frictional heat generation during the exploration process, the ultra-high pressure, high impact load of the drill bit bearings, and the high tem...
