摘要
以渤海湾盆地Q油田明化镇组河流相砂体为例,采用单井分析方法并结合地震资料,分析了河流相复合砂体内部叠置特征,划分出多期砂体的切割叠置、边部侧切和边部叠加3种类型。阐述了表征复合砂体内部结构的意义,为井位部署及开发方案的编制提出了合理的建议:针对多期砂体的切割叠置存在的不确定性,提出了优化钻井顺序、设置钻井决策树、先评价后开发的建议;针对多期砂体的边部侧切和边部叠加形成的复合砂体,其内部隔夹层性质稳定的特点,提出了采用水平井开发,优化注采关系的建议。
Taking the fluvial sandbody of the Minghuazhen formation in Q oilfield in Bohai Bay as an example,this paper analyzes the in-ner superimposed characteristics of fluvial complex sandbody by means of single well analysis and seismic data,presents three types of thecut stacking,edge lateral cutting and edge superimposition of multi-stage sands,elaborates the significance of such a complex sandbodycharacterization,and proposes rational suggestions for well deployment and working out development plan in this area. For uncertainty ofthe cut stacking existence,it optimizes the drilling sequence and sets the drilling decision tree,and then proposes the suggestion of makingevaluations followed by development; for the complex sandbody formed by edge cutting and edge superimposition,and the existence of innerinterbeds,it proposes a suggestion of using horizonal well process for development of this oilfield and optimizing injection-production relations.
