| titleOfInvention | A kind of drilling fluid Organic Friction-Reducing agent and preparation method thereof |
| abstract | A kind of drilling fluid Organic Friction-Reducing agent, is made of following components, and each component is matched according to quality summation 100%: 45-65 parts of metal salts of organic acids, 15-35 parts of mineral oil, 5-10 parts of emulsifier, 8-15 parts of extreme pressure agent.When preparation, taken amount carries out reaction 4-6h under the conditions of 50-90 DEG C of temperature, obtains yellow or brown liquid is anti-friction composition successively by each component raw material merging reaction kettle after taken amount according to the proportion.Casing and drilling rod surface are adsorbed on by organic anion, formed one layer of high-intensitive extreme boundary lubrication film play the role of it is wear-resistant, alternative or part substitution lubricant, reduces lubricant use cost, suitable for high angle hole, horizontal well, high density drilling fluid and long period prospect pit. |
