摘要

用含氧溶剂混合物代替芳烃和萜烯溶剂去除表面有机沉积物的技术可行性已经得到证实。采用二烷基醚和二烷基烷醇的混合物制备了微非均相溶剂。这些微非均相溶剂表现出独特的性质,可以有效地增溶和去除表面的有机沥青质烃沉积物。微非均相溶剂的主要应用是去除井筒和近井区域的有机沉积物,从油砂和含油污泥中回收稠油,以及重油加工设备的清洗。

Micro-Heterogeneous Solvent Mixtures for Removal of Organic Deposits from Various Surfaces
The technical feasibility of using oxygenated solvent mixtures as an environmental and ecological friendly alternative to aromatic hydrocarbon and terpene solvents for removal of organic deposits from surfaces has been demonstrated. Micro-heterogeneous solvents were prepared using mixtures of di-alkyl ethers and 2-alkyl alkanols. These micro-heterogeneous solvents exhibit unique properties and are effective in solubilizing and removing organic asphaltenic hydrocarbon deposits from surfaces. The main applications of micro-heterogeneous solvents are in organic deposits removal from wellbores and near wellbore regions, heavy oil recovery from oil sands and oily sludges, and heavy oil processing equipment cleaning.
