本文根据油藏工程理论,推导出地下力场与油藏含油饱和度变化规律的关系;根据沉积韵律、沉积能量所形成的储层孔、渗条件的变化规律,分析了低饱和度油层的成因特点,提出利用录井显示结合油水界面、沉积特征识别低饱和度油层的有效方法。

According to oil reservoir engineering theory ,the relationship of variation rule between underground force field and oil saturation of reservoir is concluded. The variation rules of porosity and permeability of reservoir formed by sedimentary rhythm and energy are used to analyze the genesis characteristics of oil reservoir with low saturation, providing an effective identification method of low saturation reservoir with logging shows combined with oil-water interface and sedimentary properties.
