陆相地层精细对比方法及应注意的问题

Methods of fine correlation and its matters needing attention in terrestrial formation.

在陆相油藏的精细描述中 ,地层的划分和对比是描述的基础 ,其研究单位已细化到了沉积时间单元或韵律小层 ,以往以岩心为主的地层划分对比方法不再适应这种研究精度的需要。通过在胜利油区的工作实践 ,总结出组合测井曲线对比、相控对比、旋回对比及趋势对比等地层精细对比方法。文章对这些方法进行了简单介绍 。

Stratigraphic classification and correlation are a foundation in the fine description of terrestrial reservoirs. The former correlation methods that based in well cores couldn′t meet the needs of this research accuracy since its research unit of strata has been divided into depositional time element or rhythm subzone. By several years working experience in Shengli petroliferous province, some fine stratigraphic correlation methods are summarized such as the merged curve correlation, the faciescontrolling correlation, the cycle correlation and the trend correlation and so on. These methods are introduced simply, and the applicable range and the problems that should be paid attention to are analyzed in this paper.
