摘要： Naphthenic acid solids and/or emulsions can be inhibited by introducing an additive to crude oil prior to or concurrent with the deprotonation of the naphthenic acids present in the crude oil. The additives may be surfactants and can be amines, quaternary ammonium compounds, quaternary phosphonium compounds, and mixtures of both. The additives may also be linear compounds having at least two carboxylic acid or acrylic acid functional moieties.
摘要翻译： 在原油中存在的环烷酸去质子化之前或同时将引入添加剂的添加剂加入到环烷酸固体和/或乳液中。 添加剂可以是表面活性剂，可以是胺，季铵化合物，季鏻化合物，以及二者的混合物。 添加剂也可以是具有至少两个羧酸或丙烯酸官能部分的线性化合物。

摘要： Amines or ammonia and amines may be used to enhance recovery of heavy hydrocarbons. The amines or ammonia and amines alone or with water, steam or an oil solvent are combined with the heavy hydrocarbons to promote the transport of the heavy hydrocarbons. The amines or ammonia and amines may be injected downhole or admixed with heavy hydrocarbon containing ore on the surface, optionally with water or steam. Ammonia may be used alone with high quality steam.It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
摘要翻译： 可以使用胺或氨和胺来提高重质烃的回收率。 单独或与水，蒸汽或油溶剂的胺或氨和胺与重质烃混合以促进重质烃的运输。 胺或氨和胺可以在井下注入或与表面上的重质含烃矿石混合，任选地加入水或蒸汽。 氨可以单独使用高品质的蒸汽。 要强调的是，该摘要被提供以符合要求摘要的规则，这将允许搜索者或其他读者快速确定技术公开的主题。 提交它的理解是，它不会用于解释或限制权利要求的范围或含义。

摘要： A polymer useful as a flocculent, demulsifier or water clarifier may be selected from those having the general formula: wherein R is an alkyl group having from 3 to about 7 carbons and X is an integer having a value of at least two. The alkyl group may be linear or branched.
摘要翻译： 可用作絮状，破乳剂或水净化剂的聚合物可以选自具有以下通式的聚合物：其中R是具有3至约7个碳的烷基，X是具有至少2个值的整数。 烷基可以是直链或支链的。
