摘要:
巴西桑托斯盆地发育多种成因类型的岩浆岩,给油气勘探带来了挑战。根据钻井及地震资料,桑托斯盆地岩浆岩可以划分为火山通道成因相、喷发溢流成因相及侵入成因相等3种成因类型,各种成因类型的岩浆岩在空间上相互依存而构成一个完整的岩浆岩发育序列,其地震反射几何形态及内幕结构具有较大的差异,其中火山通道成因相和喷发溢流成因相可进一步细分为3种地震亚相类型。依据断裂活动性、地震反射特征及同位素定年分析,桑托斯盆地岩浆岩活动可划分为断陷期火山活跃阶段、拗陷期火山活跃阶段和漂移期火山活跃阶段等3个活动期次。结合研究区岩浆岩类型多样、地质地球物理特征差异明显的特点,针对不同类型的岩浆岩总结出不同的识别刻画方法。本文研究成果可以为桑托斯盆地勘探地质风险的有效规避及有利勘探方向的优选提供有力支持。
Abstract:
A variety of genetic types of magmatic rocks have been developed in the Santos basin of Brazil, which poses a challenge to oil and gas exploration. According to the drilling and seismic data, the magmatic rocks in the Santos basin can be divided into three genetic facies of the volcanic channel genesis, the eruption and overflow genesis, and the intrusive genesis. The magmatic rocks of various genetic types are interdependent in space to form a complete magmatic rocks development sequence that shows great differences on seismic reflection geometries and internal architectures. Among them, the volcanic channel genetic facies and the eruption and overflow genetic facies can be further subdivided into three types of seismic subfacies. According to the fault activity, seismic reflection characteristics and isotope dating analysis, the magmatic rock activities in the Santos basin can be divided into three active periods, namely, the volcanic active stage in the rifting period, the volcanic active stage in the depression period and the volcanic active stage in the drift period. Combined with the characteristics of various types of magmatic rocks in the study area and obvious differences on geological and geophysical features, different identification and characterization methods have been summarized for various types of magmatic rocks. The research results in this paper can provide strong supports for the effective avoidance of exploration geological risks in the Santos basin and the optimization of favorable exploration directions.
