| titleOfInvention | A kind of reversible emulsifier, preparation method and the reversible emulsion drilling fluid of environment-friendly type and application |
| abstract | The present invention relates to a kind of reversible emulsifier, preparation method and the reversible emulsion drilling fluids of environment-friendly type and application.The initial feed of the reversible emulsifier is C10-C20 kiber alkyl amine, C10-C20 alkyl sulfonic acid, perfluoro octyl sulfonic acid, monoxone, and additive is isopropanol, paregal O -15, paregal O -8.The reversible emulsion drilling fluid of environment-friendly type is will be after oily phase, reversible emulsifier, water phase high-speed stirred, carbon number is added less than 4 alcohol, the straight chain alcohol of carbon number 8-14, quaternary ammonium salt-modified organobentonite, humic acid fluid loss additive, calcium oxide, choline chloride, weighting material is added, so that drilling fluid reaches the density of needs.The present invention also provides a kind of phase inversion process of reversible emulsion drilling fluid, according to needed for production, it is convenient to carry out the phase inversion of drilling fluid, and drilling fluid is all highly stable under W/O, O/W two states, may be reused. |
