摘要
油藏只能出现在有利于油气运移的温度和压力的地方.温度对原油的相态和生物降解作用有十分密切的关系,因此有可能根据圈闭的温度发育史和原油性质推测油藏形成时间。通过研究认为,珠江口盆地(东部)油藏主要形成于中中新世中期以后,因此本区众多的第三纪晚期形成的构造值得重视。
It is believed that petroleum reservoirs or oil accumulations only appear where proper temperature and pressure exist for hydrocarbon migration. Temperature generally affects phases of subsurface hydrocarbon and relates closely to biodegr—adation of oil.Therefore it is viable to time formation of an oil reservoir with its temperature history and properties of the oil in it This study concludes that oil reservoirs in the eastern Pearl River Mouth basin predominantly formed after the middle par t of middle Miocene. Thus a great deal of prospects there formed in Neogene deserve careful consideration for further oil hunting.
