永安镇油田沙二下地层特性的研究

RESERVOIR CHARACTERISTICS BELOW S_2 FORMATION AT YONGANZHEN OILFIELD

利用岩心分析和测井资料.对永安镇油田几口关键井的岩性、物性、电性和含油性之间的关系进行了研究.建立了该区S_2下储层四种特性之间的关系式.结果表明.该区四种特性的相关性较好。所得到的计算孔隙度、渗透率、含油饱和度和泥质含量的经验公式.经实际资料计算与取心分析资料的误差分析检验.精度较为可靠.为该区的储层特征、油气水分布规律和沉积微相研究提供了理论依据.

This paper studies the rock property, physical properties, logging paramers and oil-bearing characteristics in the reservoir below S2 formation of some key wells by using the data of core analysis and log information. The correlations of the four properties were established. The equations for calculating porosity, permeability, oil saturation and clayey content were proved reasonable, which can provide a basis for the further study of the reservoir property in this area.
