摘　　要：受地震资料本身分辨率的影响,小断层的识别已成为海上油气开发的难点,通过近几年的技术总结,目前在南海西部海域复杂油气藏ODP实施随钻分析研究工作中常用的小断层识别技术主要包括方差体技术、相干体技术、蚂蚁体技术以及曲率体技术等,每个技术又存在多种小的分支。经实践表明各个技术都有其适应范围,对这些技术进行优化并选择合适的参数组合可以获得较好的识别结果。At present,the commonly used small fault identification techniques in the ODP implementation of complex oil and gas reservoirs in the western South China Sea mainly include variance body technique,coherence body technique,ant body technique,and curvature body technique,each of which has multiple small branches.Practice has shown that each technology has its own applicability,and only by selecting appropriate parameters can better recognition results be achieved.
