摘　　要：原油开采中油井的清蜡防蜡是保证原油产量的重要措施，研制的Ｏ／Ｗ乳液型清蜡剂以化学法清蜡为主，在体系中引入发热剂，借助发热剂的化学反应的热效应，实现热溶清蜡作用。室内试验结果表明，复合型清蜡剂的溶蜡速率可达３２４．２４ｇＬ（－１）ｈ（－１），比油基型清蜡剂的溶蜡速率提高３．０１倍，比单纯乳液型清蜡剂的溶蜡速率提高５９．２％。该清蜡剂还具有使用方便、安全、耐候性好等特点。In order to maintain the output of an oil well,it is important to prevent it from wax depositing and remove the wax.A highly efficient wax removal agent was prepared,which is an O/W emulsion liquid and contains several chemical compounds as heating agents. Laboratory experiments showed that 324.24 grams of wax can be melted in one liter of this agent per hour.The melting rate is 3.01 times faster than in an oil base wax removal agent CCl_4 and 1.592 times faster than in a normal emulsion wax removal agent. This agent is also safe, stable and easy to use.
