有时往往遇到野外送来一些泥浆样品,让实验室决定其中含有的油是否原油抑是加工油。在这项工作试验中,稍有一些体会,简述如下: 钻机及柴油机所用的加工油,有柴油、机油、黄油等。所以在送泥浆样品时,野外队应将所用不同类型的加工油一起送来,把加工油各用氯仿溶解配成一套3～10级毛细条系列。便于以后与泥浆抽提物相互比较。 由于泥浆中有时夹杂有有机物以及在含煤地区中找油时有煤屑的沾污,因而用氯仿抽提后的萃取液颜色往往为黄褐色或深褐色,所抽提之毛细条发光亦为黄褐色或黄兰色,发光很强,这些现象易误认为原油。一般加工油或原油除沥青质组份外极易溶于石油醚中。但加工油中含沥青质也较少,因而用石油醚来代替氯仿抽提,可以避免以上有机物或煤屑大量溶解的一些不利因素。
Sometimes often encountered in the field sent some mud samples, allowing the laboratory to decide whether the oil contained in crude oil is processing oil. In this work trial, a little experience, briefly as follows: Drilling rig and diesel engine processing oil, diesel, oil, butter and so on. Therefore, when sending mud samples, the field team should send different types of processing oil used together to dissolve the processing oil with chloroform to form a series of 3 to 10 capillary strips. For later comparison with mud extract. Due to the mud sometimes mixed with organic matter and oil in the coal-containing areas when there is contamination of the coal dust, so chloroform extraction of the extract color is often brown or dark brown, the extraction of the capillary light is also Tawny or yellowish blue, very luminous, these phenomena easily mistaken for crude oil. General processing of oil or crude oil except asphaltene components easily soluble in petroleum ether. However, asphaltene in processing oil is also less, so using petroleum ether instead of chloroform extraction, can avoid some of the above organic matter or coal dissolved a number of unfavorable factors.
