摘要
本文考察了胶质,沥青质对原油-表面活性剂-盐水体系相行为的影响。实验结果表明,原油对体系相行为的影响主要是其中的胶质引起的,沥青质几乎不产生影响。
The effects of resines and asphaltenes in crude oils on the phase behavior of oil/surfac- tant/brine systems are investigated experimentally.Introducing both resines and asphaltenes into the oil phase leads to decreasing solubilization parameter of the systems.The optimum salt concentration of systems is lowered with resines being added to the oil phase but is un- altered when asphaltenes exist in the oil phase.Similar changes in phase behavior of such systems are observed when resines and crude oil are introduced into the systems.The opti- mum salt concentration is shown to be a standard parameter of these systems from which equivalent alkane carbon number(EACN)of the oils under study can be estimated.
