Problems solved by technology

[0005] However, the currently used drilling fluid has a poor use effect and poor high temperature resistance, which can easily lead to the failure of the lubricating boundary film attached to the surface of the drill bit, resulting in a decrease in the lubricating effect

Abstract

The invention discloses a high-temperature-resistant lubricating material for a water-based drilling fluid and a preparation method of the high-temperature-resistant lubricating material. The preparedmaterials comprise sulfonated cotton seed oil, graphite, lignite resin, iron-chromium lignosulfonate, petroleum sodium sulfonate, aluminum nitride powder, caustic soda and water. Sulfonated cotton seed oil serves as main drilling fluid and can lubricate the metal surface of the drill bit, a boundary film and a secondary structure are formed on the surface of the sulfonated cotton seed oil, the durable lubricating effect is achieved, meanwhile, aluminum nitride powder is matched to improve the heat dissipation effect of the lubricating boundary film on the surface of the drill bit, and therefore the temperature resistance effect of the device can be improved.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a high-temperature-resistant lubricating material for water-based drilling fluid and a preparation method thereof. Background technique [0002] The work of using mechanical equipment or manpower to drill the formation into holes from the ground is called drilling. Usually refers to the exploration or development of liquid and gaseous minerals such as oil and natural gas to drill boreholes and large-diameter water supply wells. Drilling is widely used in national economic construction. [0003] At present, rotary table drilling is widely used in my country's oil (gas) fields. The main equipment includes derrick, operating platform, diesel engine, drilling rig, drilling tools, mud pump, generator, testing equipment, fuel oil tank, boiler, etc. [0004] At present, when drilling, it is often used to lubricate and protect the drill bit. Drilling fluid is a general term for vario...
