| titleOfInvention | A kind of lubricant for drilling fluids and its application |
| abstract | The invention discloses a kind of lubricant, including following components：Macromolecular sulfurised ester, silane coupler, emulsifying agent and base oil, wherein the macromolecular sulfurised ester is selected from the C containing at least one double bond 16 ‑C 24 The sulfide of straight chain fatty acid polyol ester.According to lubricant provided by the invention, the extreme boundary lubrication coefficient of high density base slurry can be greatly lowered, it is small on drilling fluid rheology influence, beneficial to thin and tough mud cake is formed, reduce fluid loss, the drilling operation available for horizontal well, high angle hole and extended reach well. |
