摘要:
墨西哥湾油气资源非常丰富，与盐岩形变相关的圈闭的落实是该区勘探的主要难题,亟待形成一套有效的盐构造识别与圈闭落实技术。以墨西哥博格斯盆地深水区为研究靶区，利用地震、钻井和重力资料，从盐岩的岩石物理性质出发，根据浅层异地盐岩、深层原地盐岩岩、盐岩流动通道和围岩的地震反射特征，总结形成了一套以双层盐岩构造识别为核心的圈闭落实关键技术组合，主要包括：双层盐岩构造雕刻与分析技术、基于地震-物模的多信息断裂解释技术、基于标志层约束的全三维层位解释技术、基于处理解释一体化的盐模型判别技术。应用该项技术组合，完成了研究区多个重点目标的精细落实，其中A圈闭钻探证实构造落实可靠。形成的技术体系也可为其他含盐盆地的盐相关构造解释和分析提供参考。
Abstract:The Gulf of Mexico is famous for its rich oil and gas resources. Salt related trap verification is the key issue in basin exploration. Therefore, it is necessary to establish an effective comprehensive interpretation technology. Taking Burgos Basin as the research area, based on seismic, well-logging, and gravity data, the petrophysical properties of salt was studied, after which a set of key technology for salt-related trap interpretation was summarized considering the seismic reflection characteristics of shallow allochthonous salt, deep autochthonous salt, salt feeder, and surrounding formation The technological package includes double-layer salt identification and analysis technology, multi information fault interpretation technology based on seismic and physical model, full 3D horizon interpretation technology based on marker horizon constraint, and salt model discrimination technology based on the integration of processing and interpretation. By applying the technology set, several key targets were interpreted accurately, which is proved by drilling at the A trap with an oil discovery. Therefore, the multi-technology approach can be used as a reference to salt-related trap interpretation and analysis in other similar salt basins.
