| titleOfInvention | A kind of low oil-water ratio emulsion drilling fluid of shale horizontal well high density |
| abstract | The invention discloses a kind of low oil-water ratio emulsion drilling fluids of drilling shale horizontal well high density, it is composed of the following raw materials in parts by weight: 180 parts of 3# white oil, 30% 120 parts of calcium chloride solution, 2-5 parts of primary emulsion, auxiliary emulsifier 4-8 parts, reversible emulsifier 12-18 parts, 5-10 parts of calcium oxide, 2-5 parts of organoclay, 3-8 parts of sealing agent, 0.5-3 parts of extracting and cutting agent, 6-12 parts of calcium carbonate, 0-800 parts of barite, wherein, primary emulsion is made of ready denier oil acid and maleic anhydride, auxiliary emulsifier is made of higher fatty acid salt and higher aliphatic acid polyol ester, reversible emulsifier is made of 9- alkene stearic acid formicester and hydroxyethyl ethylenediamine, extracting and cutting agent is by styrene, methyl methacrylate and 16 rouge of acrylic acid are made.Oil-water ratio is 6:4, has stronger inhibition dispersibility and shut-off capacity, lubricity is good, and heat-resisting property is good, is applicable to shale deep-well horizontal segment drilling well demand. |
