Химический состав добываемой и остаточной нефти Илишевского месторождения

Химический состав добываемой и остаточной нефти Илишевского месторождения

Abstract

Comparative analyses of the chemical composition of crude and residual petroleum from the Bashkortostan Ilishewskoye oil field are made. The groups of asphaltenes, neutral and sour resins, sum of paraffin-naphthenic and aromatic hydrocarbons are obtained in identical conditions by selectively separation from the petroleums. The structure-group composition of sulfur organic compounds in the concentrate extracted by sulfolane from the crude petroleum is found and identified by the technique of chromatography mass spectrometry of 18 benso-, dibensothiophenes structures and two disulfides.

Сопоставлены физико-химические характеристики добываемой и остаточной нефти Илишевского месторождения Башкортостана. Селективным разделением нефтей в сопоставимых условиях получены группы асфальтенов, нейтральных и кислых смол, суммы парафинонафтеновых и ароматических углеводородов. Методом хроматомасс-спектрометрии определен структурно-групповой состав сероорганических соединений в концентрате, выделенном сульфоланом из добываемой илишевской нефти, идентифицированы 18 бензои дибензотиофенов, преимущественно метили этилзамещенные, и два дисульфида.
