【摘要】：针对块状、复杂岩性区地震储层预测的难题,提出岩性地貌体概念。它是沉积体的岩性和形态特征的综合体,也是沉积体和纵横向反射结构特征对应关系的综合体,它的类型由地质体的沉积相、岩性、成层性和地震纵横向反射结构综合划分。该方法试图综合利用地震相、地震地貌及反演等多种信息,采用双域双面沉积体边界解释技术,降低复杂岩性预测时的多解性。提供岩性地貌体方法的关键技术及工作流程,并针对岩性复杂的湖底扇沉积进行了应用。研究中优选岩性地貌表征属性,并在平面-剖面相互约束下完成岩性地貌体解释。这套基于岩性地貌体的相控储层预测技术,对于块状、横向变化快、岩性复杂的湖底扇储层预测效果明显。
[Abstract]:In view of the difficult problem of seismic reservoir prediction in block and complex lithologic areas, the concept of lithologic geomorphology is put forward. It is a synthesis of lithology and morphological characteristics of sedimentary bodies, as well as the corresponding relationship between sedimentary bodies and longitudinal and horizontal reflection structural characteristics. Its types are comprehensively divided by sedimentary facies, lithology, stratification and seismic longitudinal and transverse reflection structures of geological bodies. This method attempts to make comprehensive use of seismic facies, seismic geomorphology and inversion information, and adopts the technique of boundary interpretation of double-sided sedimentary bodies in two domains. To reduce the multiplicity of complex lithology prediction, to provide the key technology and work flow of lithologic geomorphologic body method, and to apply to the complicated lithologic sublacustrine fan deposition. The lithologic geomorphologic body interpretation is completed under the mutual restraint of plane and section. This set of facies controlled reservoir prediction technology based on lithologic geomorphology body has obvious prediction effect for massive, fast lateral change and complicated lithologic sublacustrine fan reservoir.
