松辽盆地红岗北地区扶余油层精细构造解释与储层预测的开题报告
摘要：
本文以松辽盆地红岗北地区扶余油层为研究对象，通过搜集区域地质资料、测井曲线、地震资料等，运用地层学、构造地质学、沉积学等学科方法，对该区域精细构造进行了解释，并结合区域地质特征与储层属性，对其储层进行了预测。
研究发现，红岗北地区扶余油层主要沉积于中—上侏罗统，地层上部为准水平展布的延安组和下延长组，下部为具有较强倾角和变形特征的下侏罗统延长组。通过对测井曲线和地震资料的分析，发现该区域存在多个次级构造，主控构造为北西向的芫泡子断裂，次级构造包括斜北向断层、皱褶、隆起等，这些构造对储层形成及分布起重要作用。
对于储层预测，本研究采用综合分析的方法，结合测井解释、地震属性及规律、区域地质特征等因素，对储层进行了研究。通过分析发现，该区域储层类型以砂岩居多，储层储集空间主要受砂体发育程度、构造、岩性、含油饱和度等因素影响，预测表明该区域储层具有较好的勘探潜力。
