Abstract

Настоящее изобретение относится к способу предотвращения образования, уменьшения количества и/или удаления асфальтен-парафин-восковых преципитатов на поверхностях, контактирующих с сырой нефтью внутри нефтяных скважин от забоя до устья скважины, в напорных трубах и нефтепроводах, посредством использования биоколлоидных суспензий. Более конкретно, способ включает совместное добавление (а) микроорганизма (или микроорганизмов), способного реагировать с компонентами сырой нефти и растворять их и/или устойчивого к компонентам сырой нефти, (б) органических или неорганических добавок или (в) их смеси в трубы и предоставление полученной таким образом суспензии, содержащей микроорганизмы, возможности действовать в течение желаемого времени. Суспензию можно использовать для разложения, вымывания и удаления твердых углеводородов и смесей длинноцепочечных углеводородов, а также для предотвращения их образования.Международная заявка была опубликована вместе с отчетом о международном поиске.The present invention relates to a method of preventing the formation, reduction and / or removal of asphaltene-paraffin-wax precipitates on surfaces that come into contact with crude oil inside oil wells from bottom to bottom, in pressure pipes and pipelines, through the use of biocolloidal suspensions. More specifically, the method involves co-adding (a) a microorganism (or microorganisms) capable of reacting with and dissolving crude components and / or resistant to components of crude oil, (b) organic or inorganic additives, or (c) mixtures thereof into pipes and providing the thus obtained suspension containing microorganisms, the ability to act within the desired time. The suspension can be used to decompose, wash out and remove solid hydrocarbons and mixtures of long-chain hydrocarbons, as well as to prevent their formation. The international application was published along with an international search report.
