为了确保大庆油田二次开发及三次采油的顺利实施,重新开展了杏南地区主要油层的高分辨率层序地层划分和对比的分析和研究工作.运用高分辨率层序地层学原理对不整合面、整合面、初次湖泛面及最大湖泛面等各级界面进行识别和对比.通过对层序边界形成机理、识别方法及标志、边界类型及特征等方面的研究,结合各级层序内部结构特征,建立研究区目的层的等时地层格架.依据各级层序界面标志,研究区目的层被分为2个长期基准面旋回LSC1和LSC2;3个中期基准面旋回MSC1、MSC2及MSC3;35个短期基准面旋回.%In order to solve the difficult problem of well testing interpretation in Hailar oilfield, 194 copies of formation water well testing data from 2000 to 2008 in the study area are collected and arranged, considered seven formation water chemistry component variables such as CO23-, HCO3-, C1- 、S24+, Ca2+, Mg2+, K+ + Na+, applied the principle and method of discriminant analysis in mathematical geology and established the quantitative discriminant model for determining water layer. By back sentencing and testing, the fight judgment ratio of the model was 95.9％ and it proved the model is significant. 17 formation water well testing samples in 2009 was convicted by the discriminant model and its right judgment ratio is 88％. It shows the model is reliable and can be used in well testing interpretation.
