这里所述的方法与研究伏尔加乌拉尔中生代石油、亚得里亚北高加索第三纪石油时所用之方法在原理上是一样的。 预处理:当样品中有极为稳定的乳胶体的油层水时,为破坏此乳胶体,分离层间水中之盐类并去除机械杂貭,可以将样品与氯仿按1:1之重量此彻底混合,然后加入蒸溜水,用分液漏分去水层,继续用水 The method described here is the same in principle as it was for the study of the Mesozoic oil of Volga Urals and the Tertiary oil of the Northern Caucasus of Adria. Pretreatment: When the sample contains a very stable latex of reservoir water, the sample may be thoroughly mixed with chloroform at a weight ratio of 1: 1 to destroy the emulsion, remove salts in the interlayer water, and remove mechanical impurities , Then add distilled water, with the separation of leakage to the water layer, continue to use water
