| 摘 要： | 塔里木盆地北缘工区地表类型比较复杂,主要目的层奥陶系埋藏较深,由于碳酸盐特有的复杂性,其内部很难形成波阻抗界面,反射微弱,成像较差,资料分辨率和信噪比相对较低。1999、2003、2006年3次在不同区域采集的地震资料,其分辨率、信噪比等各不相同,达不到地质应用的标准而需要进行连片处理。在分析原始地震资料基础上,采用统一网络技术、高精度静校正统一计算及剩余静校正技术、振幅补偿、叠前子波处理等技术进行地震资料处理,消除频率、振幅、相位差异;压制面波、小波干扰和各种异常振幅;提高地震资料纵横波分辨率等,使地震资料满足连片区块内整体构造成图以及储层预测的需求。

| Abstract: | The northern margin surface in the Tarim Basin work area is complex,and its target zone is Ordovician Buried deeply.As specific complexity of the carbonate,it is difficult to form impedance interface internally and will lead to weak reflection,poor image,data resolution and low signal-to-noise.From 1999 to 2006 three seismic data acquisition were completed in different regions,but the original seismic resolution and signal-to-noise diverse from each other,and it can't reach the standards of geological appli... |
