摘要
准噶尔盆地莫北凸起莫7~莫11井区应用了大面元三维地震勘探,其地震资料应用单一的解释技术难以刻划小断层.在处理解释一体化攻关的基础上,解释过程中以新数据体为主体,采用了层位解释技术、速度分析与构造成图解释技术以及多种方法相结合的断裂解释技术(面块切片解释技术、构造应力场分析解释技术、构造层内标志层控制解释技术、古构造恢复解释技术、正演模拟解释技术).解释结果有了明显的改善,断裂系统更合理,并且识别出了一些对油气成藏起重要作用的小断裂(变换断层).解决了以前地震资料解释结果与试油、测井、钻井解释结果难以吻合的问题.
The extensive area element 3D seismic prospecting was applied in Mo7-Mo11 oil well district of Junggar Basin, so it is difficult to interpret small faults based on single interpretation techniques. By using many interpretation techniques, such as stratum interpretation, velocity analysis, structure drawing, time slice, stress field analysis, the interpretation technique controlled by indicative layers in the strata, the technique of resuming ancient structures and seismic forward modeling, etc., the effect of the seismic structure interpretation was improved obviously. Small faults (transforming faults) were discovered and pictured, and inconsistencies in the previous seismic data interpretation, test, logging and drilling results were solved.
