Embodiment 1

[0039] Mix zinc nitrate, thiourea, diethylenetriamine and distilled water at a molar ratio of 1:1:6:55 and put them into a stainless steel reactor with a polytetrafluoroethylene liner, seal it, and let it stand at 170°C The crystallization reaction was carried out for 10 hours. After the reaction was completed, the filter residue was obtained by washing, centrifuging, and filtering, and dried at 100°C to constant weight to obtain lubricated microspheres;

[0040] In parts by weight, take 3 parts of lubricated microspheres, 6 parts of colloidal graphite, and 10 parts of RDX and mix them into a high-pressure airtight container, and fill the high-pressure airtight container with a volume ratio of 3:1 nitrogen and argon. After detonating the mixed gas with a lead wire, let it stand for 10 minutes, and collect the carbon-coated lubricating microsphere particles;

[0041] Add 1-aminopropyl-3-methylimidazolium bromide and triethanolamine into a round-bottomed flask at a mass ratio of...

Embodiment 2

[0045] Mix zinc nitrate, thiourea, diethylenetriamine and distilled water at a molar ratio of 1:1:6:55, put them into a stainless steel reactor with a polytetrafluoroethylene liner, seal it, and let it stand at 175°C The crystallization reaction was carried out for 11 hours. After the reaction was completed, the filter residue was obtained by washing, centrifuging, and filtering, and dried at 103°C to constant weight to obtain lubricated microspheres;

[0046] In parts by weight, take 4 parts of lubricated microspheres, 6 parts of colloidal graphite, and 11 parts of black sogen and mix them into a high-pressure airtight container, and fill the high-pressure airtight container with a volume ratio of 3:1 nitrogen and argon. After detonating the mixed gas with a lead wire, let it stand for 13 minutes, and collect the carbon-coated lubricating microsphere particles;

[0047] Add 1-aminopropyl-3-methylimidazolium bromide and triethanolamine into a round-bottomed flask at a mass rat...

Embodiment 3

[0051] Mix zinc nitrate, thiourea, diethylenetriamine and distilled water at a molar ratio of 1:1:6:55, put them into a stainless steel reaction kettle with a polytetrafluoroethylene liner, seal it, and let it stand at 180°C The crystallization reaction was carried out for 12 hours. After the reaction was completed, the filter residue was obtained by washing, centrifuging, and filtering, and dried at 105°C to constant weight to obtain lubricated microspheres;

[0052] In parts by weight, take 5 parts of lubricated microspheres, 7 parts of colloidal graphite, and 12 parts of black sogen and mix them into a high-pressure airtight container, and fill the high-pressure airtight container with a volume ratio of 3:1 nitrogen and argon. After detonating the mixed gas with a lead wire, let it stand for 15 minutes, and collect the carbon-coated lubricating microsphere particles;

[0053] Add 1-aminopropyl-3-methylimidazolium bromide and triethanolamine into a round-bottomed flask at a ...

Abstract

The invention relates to a lubricant for drilling fluid and a preparation method thereof, and belongs to the technical field of lubricant preparation. The lubricant base oil capable of effectively enhancing lubricity and high temperature resistance is obtained by preferably selecting the lubricant base oil and selecting a special surfactant, and the modified lubricating microsphere particles are prepared, through the lubricating performance of the modified lubricating microsphere particles and the synergistic interaction effect between the modified lubricating microsphere particles and the lubricant base oil, the lubricating property and the high-temperature resistance of the lubricant are further optimized, and the lubricant has a wide application prospect.

Description

technical field [0001] The invention relates to a lubricant for drilling fluid and a preparation method thereof, belonging to the technical field of lubricant preparation. Background technique [0002] At present, drilling fluid lubricant is an important chemical treatment agent for drilling fluid. Drill down resistance, thereby reducing the occurrence of stuck pipe accidents. Today, with the rapid development of directional drilling technology, especially in the construction of horizontal wells, the requirements for reducing resistance are increasing day by day, and the requirements for drilling fluid lubricants are getting higher and higher. However, the current conventional lubricants used in drilling fluids have low extreme pressure film strength, poor temperature resistance and limited lubricating effect. [0003] In view of the above-mentioned defects, the designer actively researches and innovates in order to create a lubricant for drilling fluid and a preparation m...
