摘要:
基于前人扇三角洲储层构型研究成果,以贝尔凹陷苏德尔特油田兴安岭油层为例,探讨扇三角洲单期扇体的构型解剖方法及扇体组合样式。扇三角洲单期扇体的构型解剖需完成点、线、面3个层次的研究。首先,单井分析构建单期扇体与高分辨率层序构型单元的对应关系,厘定纵向研究尺度;然后,扇体连井对比搭建合适的层序地层格架,通过识别沉积旋回的横向变化刻画扇体主体和扇体侧缘部位;最后,通过地震属性手段刻画扇体的具体边界位置。通过对苏德尔特油田兴安岭油层扇三角洲沉积进行单期扇体精细解剖,总结单期扇体的3类组合样式,即孤立扇型、叠置扇型、接触扇型。其中,孤立扇型组合可进一步划分为同供给水道型、异供给水道型两种亚类;叠置扇型组合根据叠置方向的差异,可进一步划分为垂向叠置扇、侧向叠置扇两种亚类;接触扇型组合根据扇体的级次关系可进一步划分为主次接触扇、同级接触扇两种亚类。
Abstract:
Based on the previous study of fan delta reservoir architecture, taking Xing’anling reservoir of Sude’erte oilfield in Bei’er depression, China as example, the architecture description method and fan body assemble patterns of single fan in fan delta were discussed. Single fan architecture description of fan delta should be achieved in 3 dimensions, including point, line and plane. Firstly, corresponding relation between single fan and high-resolution sequence units is built to clarify the vertical scale through single well analysis; secondly, well correlation for fans is made to build proper sequence stratigraphic skeleton, and the main and margin portion of fans are identified by recognizing lateral variations of deposition cycle; finally, fan boundary is described by seismic attributes. Single fan fine description of fan delta in Xing’anling reservoir of Sude’erte oilfield was carried out, and 3 assemble patterns for single fan bodies were summarized, namely, isolated, superimposed and contact fans. Isolated fans can be subdivided into isolated fans with same supply channels and with different supply channels; according to the differences of superimposed orientation, the superimposed fans can be subdivided into vertically and laterally superimposed fans; according to the levels of fans, the contact fans can be subdivided into different-level and same-level contact fans.
