| titleOfInvention | Compound emulsifying agent that oil base drilling fluid is applicable in and its preparation method and application |
| abstract | Compound emulsifying agent being applicable in the present invention relates to a kind of oil base drilling fluid and its preparation method and application, mainly solves oil-based drilling fluid emulsifying agent less varieties in the prior art, emulsifiability, the problem of heat resistance is poor.The present invention is by using a kind of emulsifying agent for oil base drilling fluid, including following components：(1) primary emulsion, selected from least one of structure shown in formula (I)；(2) coemulsifier, selected from least one of structure alkyl phenol ether carboxylate shown in formula (II)；The ratio of the primary emulsion and coemulsifier meets 0 ＜ coemulsifiers:The technical solution of primary emulsion≤1, preferably resolve the above problem, it can be used as oil-based drilling fluid emulsifying agent, with good emulsifiability and heat resistance, the oil base drilling fluid stability of formation, temperature tolerance are preferable, can meet the special requirements such as strong retraction in oil field, high-temperature stratum drilling well and big displacement Special Drilling Operation, seaborne horizontal well. |
