针对我国大部分油田原油含蜡量均在20％以上，有的甚至高达40％，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表面活性剂润湿性、分散性的研究，筛选出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，是一种典型的多效剂。该剂成本较低，投药工艺简单，具有现场应用价值。
In view of the fact that the wax content of crude oil in most oilfields in our country is more than 20% and even up to 40%, the normal production of oil well is seriously affected. The determination of waxing and dissolving speed in solvent phase, surfactant wettability and dispersibility Study, screened out a mixed 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 the ability to dissolve the oil gel, asphaltene, is a typical multi-agent. The cost of the agent is low, the dosage is simple and has the field application value.
