Problems solved by technology

[0005] The currently widely used lubricants for drilling fluids either have high cost, or pollute the environment, or have fluorescence that affects geological logging, and none of them can well meet the cost and performance requirements of drilling fluid lubricants for large-scale horizontal well exploration and development.

Abstract

The invention discloses a lubricating agent for a shaft boring machine and a preparation method of the lubricating agent. The lubricating agent is prepared from the following constituents in parts by weight: 10-20 parts of carnauba wax, 1-5 parts of oleic acid, 0.1-0.9 parts of butylated hydroxytoluene, 1-6 parts of triethanolamine, 20-40 parts of silicon oil, 1-3 parts of microcrystalline wax, 5-10 parts of glycerin, 5-10 parts of wool fat, 1-5 parts of sodium chloride, 3-8 parts of dodecyl oleate, 0.5-2.5 parts of sodium nitrite, 1-3 parts of urea, 1-8 parts of lauryl phosphate, 0.5-1.5 parts of methylacrylic acid, and 2-6 parts of an emulsifying agent. The lubricating agent is low in cost, good in lubricating effect, easy to adhere to the surface of the shaft boring machine, high in adhesive force, capable of forming oil film on the surface to reduce resistance between friction parts and preventing water and steam from entering in the machine, high in water resistance and dirt resistance, low in friction coefficient, and very suitable for the working environment of the shaft boring machine.

Description

technical field [0001] The invention belongs to the technical field of lubricants, and in particular relates to a lubricant for drilling machinery and a preparation method thereof. Background technique [0002] During drilling and well completion operations, there will be friction between the drilling tool and the well wall and casing, and between the drilling fluid and the drilling tool, the well wall and the casing wall. During the drilling process of horizontal wells and directional wells, the action of gravity causes cuttings and drilling tools to accumulate to the lower part of the well wall, which further increases the contact area between drilling tools and cuttings, resulting in increased torque and frictional resistance, resulting in jamming Drilling and other downhole complex accidents. Lubricants can greatly reduce the frictional resistance of drilling fluids. Therefore, the drilling process of horizontal wells and directional wells has higher requirements on...
