摘要
针对靖安油田出现的“上水下油”这种独特的油层分布现象 ,利用测井、录井、薄片和压汞等资料进行了综合研究 ,分析了“上水下油”的沉积意义与形成机理 ,并对此现象进行了流体力学意义上的研究 ,指出“上水”现象是由于渗透率低、束缚水饱和度高造成的 ,在试油中不可能产液。
Aimed at a unique distribution of oil layers, called as phenomenon of “water up and oil down ” in Jing'an oilfield, a comprehensive study is carried out by using the data of well logging,borehole logging, thin sections and mercury injection The sedimentary significance and formation mechanism of “water up and oil down” are analyzed, and the phenomenon is researched hydromechanically Water up is resulted from a low permeability and a highly irreducible water saturation Fluid production is impossible during formation testing
