| 摘 要： | 根据富县探区延长组岩心、试油、物性等资料,分析了储层的岩性、物性、含油性和电性特征及四者之间的关系,确定了延长组储层物性下限,结果表明,富县探区延长组为低孔低渗-特低渗储层,物性最好的为长3储层,含油级别很少达到油浸级。

| Abstract: | According to core,oil testing,physical property data of exploration area in Fuxian,the relationship between reser-voir lithology,physical properties,oil resistance and electrical characteristics and between the four identified Yanchang reservoir properties limit have been analyzed.The results showed that Yanchang formation is of low-porosity,low and ultra-low permeability reservoirs and the reservoirs with best properties are Chang-3 reservoirs,with oilbearing type rarely reached oil level. |
