摘要
阿尔及利亚X区块主要发育大深度低幅度构造,低幅度圈闭识别与落实制约着区块的油气勘探发现.根据区块的地质与地球物理特点,在认真深入对比分析现有时深转换方法的基础上,提出了综合运用多种时深转换方法进行区域目标搜索及单个目标"量体裁衣"的多尺度时深转换方法,有效的解决了本区油气勘探中面临的低幅构造识别与落实难题,取得了较好的勘探效果.该方法能够有效的发现低幅度圈闭并提高低幅度构造成图的精度,落实局部构造,降低勘探风险,对于类似地区的低幅度构造研究具有借鉴意义.
Structures of Block X in Algeria are mainly low relief traps and they are buried deeply. Identification and Implementation of these low relief structures restrict oil and gas exploration and discovery in Block X. According to geological and geophysical characteristics, and base on fine comparison of the existing time-depth conversion methods, multi-scale time-depth conversion method was put forward, which means that regional low relief target searching was done by many time-depth conversion methods and single low relief target fine time-depth conversion was done one by one. This method effectively solves the difficulty of identifying low relief traps and obtains getter exploration results. The low relief traps can easy be found and their structures accuracy also can be effectively improved by multi-scale time-depth conversion method, which helps determine low relief structures and reduces exploration risk. The multi-scale time-depth conversion method is also a reference for similar area low relief structure study.
