针对我国大部分油田原油含蜡量较高，严重影响油井正常生产的事实，通过溶剂相清蜡溶蜡速度测定以及对表面活性剂润湿性、分散性的研究，筛选出了一种以混合烃为溶剂相和具有润湿分散能力的复合表面活性剂为乳化剂的Ｏ／Ｗ型清防蜡剂ＪＨＴ－Ｉ。性能评价研究表明，该清防蜡剂具有清蜡速率高，防蜡效果好，并具有一定的溶解油井胶质、沥青质的能力，是一种典型的多效清蜡防蜡剂。 Aiming at the fact that the crude wax content in most oilfields in China is so high that it seriously affects the normal production of oil well, the waxy wax solution speed of solvent phase and the wettability and dispersibility of surfactant are studied. Hydrocarbon as the solvent phase and the wetting and dispersing capacity of the composite surfactant as emulsifier O / W paraffin inhibitor JHT-I. Performance evaluation studies have shown that the paraffin wax has a high rate of clear wax, good anti-wax effect, and has a certain ability to dissolve the oil gel, asphaltene, is a typical multi-effect paraffin wax.
