LUBRICATING ADDITION TO DRILLING SOLUTIONS |
| abstract |
The invention relates to the drilling of oil, gas and exploration wells, namely, lubricant additives for drilling fluids. The technical result is the preservation of high levels of lubricating properties, as well as an increase in anti-grab properties at the “metal-clay crust” and “metal-metal” interface in fresh and mineralized drilling muds. Lubricant additive to drilling fluids contains, wt%: vegetable oil 40-80; hydrocarbon synthetic fluid 10-40; vegetable oil fatty acid ester 5-20; non-ionic or zwitterionic surfactant 0.5-2. 4 tab. |
