摘要： Compositions and methods of using same are described for negating asphaltene deposition in a formation, wellbore, near wellbore region, and production tubing. Compositions of the invention comprise an asphaltene solvent and a viscosity reducing agent, the asphaltene solvent and viscosity reducing agent present in a ratio so as to substantially reduce viscosity of an asphaltene-containing material while substantially negating deposition of asphaltenes either in a reservoir, in production tubing, or both when mixed or otherwise contacting the asphaltene-containing material. Methods of the invention comprise forcing a composition comprising an asphaltene solvent and a viscosity reducing agent to contact an asphaltene-containing hydrocarbon in an underground geologic formation, and producing from the formation a production composition comprising at least some of the treatment composition and at least some of the asphaltene-containing hydrocarbon under conditions sufficient to substantially negate deposition of asphaltenes in the formation.
摘要翻译：描述了使用它们的组合物和方法，用于消除地层，井筒，井眼区域和生产管道附近的沥青质沉积。本发明的组合物包含沥青质溶剂和粘度降低剂，所述沥青质溶剂和粘度降低剂以比例存在，以便基本上降低含沥青烯的材料的粘度，同时基本上不产生在储存器中生产中的沥青质沉积物管道或两者混合或以其他方式接触含沥青质的材料。本发明的方法包括强制包含沥青质溶剂和降粘剂的组合物接触地下地质地层中的含沥青质的烃，并从地层生产包含至少一些处理组合物和至少一些的含沥青质烃在足以基本上抵消地层中沥青质沉积的条件下进行。
