在油田的勘探与开发过程中,每口井完钻后都要进行油矿地球物理的测井工作,以确定井下地质剖面的岩石学类别,划分出渗透性和非渗透性地层,并指出渗透性地层中所含的是油、气或是水。确定地层中是否含油气这一工作很重要,为此,作者在油气层的解释中采用了多元统计中的二次判别函数,以便配合常规电测解释工作,提高油气层的判断成 During the exploration and development of oilfields, logging of oil-bearing geophysics should be conducted after each well is drilled to determine the petrological classification of the downhole geological profile, to divide the permeability and non-permeability strata, and to indicate the permeability The formation contains oil, gas or water. It is very important to determine whether oil and gas are contained in the formation. Therefore, the author used the quadratic discriminant function in multivariate statistics in the interpretation of oil and gas formations in order to improve the determination of oil and gas layers
