|
摘要
以层序地层学理论为基础,结合地震和测井资料,采用时频分析技术开展高分辨率层序地层划分与对比研究。根据时频计算结果,获得各级层序体的层序旋回特征,结合水进/水退沉积相、沉积间歇面、储层、盖层分布等地质信息,划分沉积地层旋回及内部精细结构。通过井震联合的多尺度匹配方法建立层序地层格架,实现井震资料在相同级别研究目标的综合解释,对经过反射空白区或断层时的两侧反射层位进行对比,从而有效提高储层预测精度,指导地震反演数据的解释,对岩性体进行从定性到定量的精细描述。形成一套完整的层序地层分析软件系统,为薄互层研究和储层预测提供技术平台。
Based on the theory of sequence stratigraphy and combined with the seismic and logging data,the division and contrast of sequence strata with high-resolution was studied by means of the time-frequency analysis technology.According to the result of time-frequency calculation,we have got the characteristics of the sedimentary cycles of different sequence bodies and divided the cycles of sedimentary strata,and the internal fine structure combining with such geological information as the distributions of the sedimentary facies in transgression and regression activities,the interstitial surface of sedimentation,the reservoirs and cap rocks,etc.The sequence strata framework was established with the well-seism coalition multi-scale matching method,realizing the comprehensive interpretation of seismic and logging data at the same level of research objectives,and in the meantime,through the contrast of both sides of reflective horizon of fault or reflective vacant area,it not only effectively improved the precision of reservoir prediction,but also directed the interpretation of inversion data as well as made fine descriptions of lithology qualitatively to quantitatively.A set of integrated analysis software systems for sequence strata was formed,providing an effective technical platform for thin interbed research and reservoir prediction.
