| 摘 要： | 为提高复杂断块区断裂识别精度,笔者基于Landmark解释软件,以渤海海域浅层断裂较为发育的渤中23构造区为例,详细对比分析识别断裂的ESP模块、Semblance模块及Structure Cube模块参数设置及识别效果。对比结果显示,结合倾角校正技术及滤波技术的Structure Cube模块对数据体进行相干体制作,可以显著提高断裂识别精度。将该方法应用到断裂较为发育的蓬莱A构造,新发现走滑断裂,为该区新增资源量约230万t。

| Abstract: | In order to improve the fracture recognition accuracy of complex fault blocks，based on the Land- mark interpretation software，we take Bozhong 23 tectonic region whose shallow faults are well developed in Bohai sea as an example， analyze the parameter setting and recognition effect of ESP， Semblance and Structure Cube fault identification module by means of detailed comparison． The comparative result shows that making coherent data body combined with dip correction technology and filtering technique，Structure Cube module can significantly im- prove the fracture recognition accuracy． Applying this method in analysis of the Penglai A structure，about 2. 3 mil- lion tons of new resource increased in the area based on the new discoveries of strike- slip faults． |
