Object is as antiwear additive；CN101157850A discloses a kind of preparation of high temperature resistant lubricant for drilling liquid by animal plant oil, using ester
Waste grease is as antiwear additive after changing, vulcanizing；CN104893688A discloses a kind of lubricant for drilling fluids resistant to high temperatures, mainly
Using synthetic Lubricating grease as lubricating additive, but added without antiwear additive.
Technology disclosed above mostly uses the substance of sulfur-bearing as antiwear additive, under the effect of high temperature extreme pressure, sulphur and metal
It chemically reacts, generates metal sulfide protective film to reduce frictional resistance and play lubricating action；But then, it passes through
Many experiments and application discovery are crossed, in circulation of drilling fluid use process, sulfur-bearing antifriction lubricant can generate under high temperature action
Hydrogen sulfide, causing corrosion to drilling rod, casing, there are major safety risks；Circulating fluid can also have the effluvium of hydrogen sulfide
Taste brings strong influence to the personal safety of wellbore construction personnel.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of wear-resistant drag reduction of drilling fluid temperature resistance
Agent has the advantages that safety and environmental protection by using inorganic nano metallic compound as antiwear additive.
