精细地震解释技术在花庄北地区的应用
|
摘要
制约高邮凹陷花庄北地区勘探的主要原因是构造的落实程度低。为此本文从研究区域断裂系统入手,通过层位综合标定技术准确标定目的层的层位,分析研究区的辉绿岩发育模式,阜三段地层产状的识别,以及通过多种方法进行断层的识别与组合优化,特别是北东向小断层的识别,最后采用变速成图技术进行时深转换。通过采用上述一套精细地震解释技术,提高了花庄北地区构造的落实程度,取得了比较好的勘探成果。
The main reason restricting the exploration in Huazhuangbei area of Gaoyou sag is structural uncertainty.For that reason,starting from studying the regional structural style,the paper creates the structural style of the studied area;analyzes the development mode of diabase in studied area and identification of E1f3 strata attitude through accurately calibrating the horizon of target with the aid of horizon integrative calibration technique;carries out fault identification and optimum composition by multiple methods(especially the identification of NE minor fault),and finally uses velocity-variable mapping technique to carry out time-to-depth conversion.Through abovementioned a set of fine seismic interpretation techniques we used,the structural determinacy has been improved in Huazhuangbei area,achieving better exploration effect.
