Problems solved by technology
The commonly used API thread grease cannot meet the requirements of the equipment. During the experiment, it was found that the thread was damaged to varying degrees, and even sticking occurred, not to mention the simplification of the drillpipe production process. This puts forward more requirements for the thread compound High requirements require thread grease to maintain lubricity and sealing performance under high temperature and high torque conditions, ensure anti-sticking ability under high torque (even over torque) conditions and simplify the drillpipe production process

Embodiment 1
[0031] Put 5.6% monobasic fatty acid, 1.5% dibasic fatty acid and 37% base oil into the reaction kettle, stir and raise the temperature, when the temperature reaches 95°C-100°C, add 1.4% alkali, 4.5% water, as alkali solution After the addition is complete, keep the temperature in the kettle at 95°C-100°C, and react for 2 hours. After the reaction, raise the temperature to 200°C-210°C, and keep at this temperature for 15 minutes for refining. After refining, cool to 80°C-100°C, add 18% molybdenum disulfide powder, 4% C18 organic molybdenum salt, 5% C22 organic lead salt, 13.5% antimony thioantimonate, 7% copperPowder, 2.5% T309, after the additive is fully dissolved, it is ground to obtain high-temperature, high-torque drill thread grease.
Embodiment 2
[0033] Put 4.05% of monobasic fatty acid, 0.8% of dibasic fatty acid and 34% of base oil into the reaction kettle, stir and raise the temperature, when the temperature reaches 95°C-100°C, add 0.95% of alkali, 3.2% of water, as alkali solution After the addition is complete, keep the temperature in the kettle at 95°C-100°C, and react for 2 hours. After the reaction, raise the temperature to 200°C-210°C, and keep at this temperature for 15 minutes for refining. After refining, cool to 80°C-100°C, add 20% molybdenum disulfide powder, 5% C18 organic molybdenum salt, 6% C22 organic lead salt, 15% antimony thioantimonate, 8% copperPowder, 3% T309, after the additive is fully dissolved, it is ground to obtain high-temperature, high-torque drill thread grease.
Embodiment 3
[0035] Put 7.3% monobasic fatty acid, 2% dibasic fatty acid and 48.8% base oil into the reaction kettle, stir and raise the temperature, when the temperature reaches 95°C-100°C, add 2% alkali, 5.9% water, when the alkali solution After the addition is complete, keep the temperature in the kettle at 95°C-100°C, and react for 2 hours. After the reaction, raise the temperature to 200°C-210°C, and keep at this temperature for 15 minutes for refining. Cool at 80°C-100°C after refining, add 10% molybdenum disulfide powder, 3% C18 organic molybdenum salt, 4% C22 organic lead salt, 10% antimony thioantimonate, 5% copper powder , 2% T309, after the additive is fully dissolved, it is ground to obtain high-temperature, high-torque drill thread grease.

Abstract
The invention discloses a preparation method of a thread grease of a drilling tool. The preparation method comprises the following steps: weighing raw materials in parts by weight in proportion; adding unitary fatty acid, dicarboxylic acid and base oil and stirring and heating; when the temperature of a reaction kettle reaches 95-100 DEG C, adding alkaline and water, and after addition, maintaining the reaction kettle at 95-100 DEG C and reacting for 2 hours; after reaction, heating the reaction kettle to 200-210 DEG C, maintaining the temperature of the reaction kettle to 200-210 DEG C and refining for 15 minutes; after refining, cooling the reaction kettle to 80-100 DEG C, adding molybdenum disulfide powder, C18 organic molybdenum salt, C22 organic lead salt, antimony thioantimonate, copperpowder and T309; and after fully dissolving, grinding to obtain the thread grease of the drilling tool. The high-temperature high-torque thread grease disclosed by the invention not only fully achieves the technique request of AT serial raise boring machines, but also can be used for simplifying the quenching step in drillpipe production, thereby achieving the expectant purpose and effect.
Description
technical field [0001] The invention relates to chemical products, in particular to a drilling tool thread grease and a preparation method thereof. Background technique [0002] A company's AT series raise drilling rigs are mainly used for drilling underground mines and expanding ventilation shafts, filling wells, pipeline wells, and excavation of large-section raises and slide shafts in various underground mines and water conservancy projects. Won the first and second prizes at the provincial and ministerial level. A certain type of raise drilling rig has filled the domestic gap and reached the international advanced level. The development of this series of drilling not only bears various dangerous high loads (up to 130,000 N) such as axial loads, internal and external pressures, formation slippage, and shearing, but also high temperature loads above 180°C. This requires that the threaded joints not only withstand various high loads, but also must ensure sealing under the...
