| titleOfInvention | Water in oil emulsion drilling fluid and preparation method thereof |
| abstract | The present invention relates to a kind of water in oil emulsion drilling fluid and preparation method thereof, mainly solve the problems, such as that Water-In-Oil Drilling fluid emulsion stability can poor, non-refractory in the prior art.The present invention by terms of mass fraction including following component：(1) 60~90 part of base oil；(2) 10~40 parts of water；(3) 2~5 parts of organoclay；(4) include that the compound emulsifying agent of primary emulsion (I) and coemulsifier (II) is no less than 0.5 part；(5) 0~3 parts of alkaline matter；(6) 0.5~3 parts of tackifier；The technical solution of the oil base drilling fluid of (7) 0.5~3 parts of fluid loss additive etc. and preparation method thereof, preferably resolves the problem, can be used for strong retraction, high-temperature stratum and needs to bore in the drillng operations of occasions such as big displacement exceptional well, seaborne horizontal well. |
