摘要: 针对岩性圈闭边界条件复杂、形态不规则、赋存状态隐蔽等特点,采用层序地层和"三相"联合解释技术为基础的地震信息多参数综合分析方法进行岩性圈闭识别、优选、描述与评价。该方法包括地震相分析、地震反演与储层预测、地震属性分析、流体势分析与含油气检测、三维可视化等。通过在江汉盆地蚌湖地区和吐哈盆地胜北地区的应用,初步证实了该方法在岩性圈闭识别、优选、描述与评价方面的针对性和实用性。应用表明,该方法在地震资料品质较好、构造相对简单的中等勘探程度以上地区的岩性油气藏勘探方面具有良好适用性。其中地震数据体选择、分析时窗大小的确定、顶底约束层位解释、不同频段相关属性参数优选等是该方法应用的关键。Abstract: In view of the complexity in boundary condition,irregularity in shape and subtle in occurrence of lithologic traps,a practical approach of identification,preference,description and evaluation of lithologic traps is put forward in this paper,which is the multi-parameter analysis of seismic data based on sequence stratigraphy and "three facies" integrated interpretation.This method mainly includes seismic facies analysis,seismic inversion and reservoir prediction,seismic attributes analysis,fluid potential analysis and hydrocarbon detection,3-dimensional visualization etc.The applications in Banghu area of the Jianghan Basin and Shengbei area of Turpan-Harmy Basin preliminary show the effectiveness and practicability of this approach in identification,preference,description and evaluation of lithologic traps.The practical shows that this approach is suit for lithologic reservoir exploration of the area with good quality of seismic data,simplicity in structure and medium or matured exploration area.And the selection of seismic data,definition of the size of time-widows for analysis,interpretation of top and bottom constraint horizon,optimization of seismic attributes in different frequency band are the key points for this approach.
