【摘要】 南阳凹陷东部核二段储层基本为三角洲前缘亚相沉积体系,储层岩性以细砂岩和粉砂岩为主。通过研究取心井储层岩性、电性、物性及含油性及之间的内在关系,拟合了相关性较好的测井资料处理解释模型;并做出了试油资料与相应储层岩性、物性及电性等参数的交汇图,得到了油、水、干层的定量解释标准,从而为实现储层参数由取心井到非取心井的定量求取,为进行测井资料二次数字处理提供了可靠的基础。更多还原

【Abstract】 Reservoirs in Eh2 in the east of Nanyang Depression is essentially of delta front subfacies depositional system, reservoir physical property is dominated by fine sandstones and siltstone. Four properties, such as lithology, electric property, physical property and oil-bearing property and their inherent relations are studied, the model for logging data processing and interpretation are established, a crossplot of 4 properties is made, by which a criterion for quantitative interpretation of oil, water and dry layer is obtained, and reliable basis is provided for quantitative calculation of reservoir parameters from coring wells to uncoring wells, as well as for secondary process of logging data.更多还原
