高分辨率三维地震勘探技术在莫北油田的应用
|
摘要
通过采用较小的CMP面元、较高的覆盖次数、炮检优化组合、选用中频检波器接收、大折射-沙丘曲线法静校正,处理应用动静校正迭代、高精度速度分析等方法和技术,首次在准噶尔盆地大沙漠区获得了高信噪比、高分辨率的三维地震资料。目的层侏罗系2.0～3.0s,有效频宽达10～90Hz,主频50Hz。资料解释新发现了17条小断层(断距10～20m)。
s: By using the technology of medium frequency geophone, small CMP bin,high coverage,optimizing shot-receive line pattern,big refraction-dune curve method,dynamic static correction iteration and high resolution velocity analyses ,high SNR(Signal-to-Noise Ratio) and high resolution 3-D seismic data has been gathered the first time at the massive desert of Zhungaer Basin. The travel time and frequency range found at the interest zone Jurassic system is 2.0～3.0s and 10～90Hz,main frequency is 50Hz. Through interpretation of the seismic data, another new 17 minor faults has been found(fault throw 10～20m).
