摘要
笔者旨在依靠重磁、遥感、GIS信息综合分析等技术手段,从宏观裂缝描述、成因分析、发育规律等方面开展多尺度碳酸盐岩裂缝发育区线性异常的综合研究,寻找不同尺度断裂、裂缝间的空间关系,作出对储层裂缝方位及发育带的预测。提出了运用重磁与遥感多元信息复合技术进行裂缝解释的思路和方法,以哈萨克斯坦阿克纠宾地区扎纳若尔和俄罗斯尤罗伯钦—托霍姆碳酸盐岩油田为例,阐明了地球物理线性异常反映的断裂和宏观裂缝的表征意义,剖析了线性异常数量化分析方法,研究了地球物理场和线性异常的分布特征,建立了研究区宏观裂缝发育模式。
Making use of the ideas and methods for interpretation of cracks,the authors employed the multi-information gravity and magnetic and remote sensing technology.The concept of linear body field of remote sensing was introduced into the interpretation of linear anomalies and linear structures of the geophysical field.The study areas are two carbonate oil fields： the Zhanazhol,Kenkiyak oilfields located in the east part of Precaspian Basin,western Kazakhstan,and the Yurubcheno-Tokhomskoye oilfields located in the west of Baykit Basin in eastern Siberia.The characterization significance of macro-cracks and fractures of the geophysical linear body is explained,the quantitative method is analyzed,the distribution features of the geophysical field and linear body of Aktobe region are studied,and the development pattern of macro-cracks in this area is established.
