高精度三维资料综合解释研究技术在永安地区的应用
|
摘要
随着勘探程度的日益提高,现有的常规地震资料已经不能适应对地下目标进行更深入研究和精细评价的要求。因此,在地质认识的指导下,利用高精度三维地震资料信息丰富的特点,应用多种地球物理方法对永安地区上含油气系统进行了解释和分析。并将层序、沉积、构造等多门学科有机结合,综合分析了这个地区油气聚集成藏的内在规律,总结、归纳了断层识别的新思路、新方法,并结合测井约束反演、地震属性分析、谱分解、含油气检测等多种技术,对储层的空间分布、圈闭的含油气性等进行了研究,并对新发现的一批圈闭进行了优选及综合评价,在勘探、开发方面取得了较好的效果。
With the increasing exploration degree,the current conventional seismic data can’t suitable for the in-depth research and precise evaluation of the underground targets.Therefore,under the guidance of geological knowledge and in virtue of the informative feature of high-accuracy 3D data,various geophysical techniques were used to interpret and analyze the petroleum system in Yongan area.Combined with such subjects as sequence,sediment and structure,a comprehensive analysis of the internal laws of hydrocarbon accumulation in this region was carried out and some new methods for fault identification was generalized.And based on such techniques as logging constrained inversion,seismic attribute analysis,spectral decomposition and hydrocarbon detection,spatial distribution of reservoir and hydrocarbon potential of traps were studied.The optimization and comprehensive evaluation of some newly-found traps were carried out,which proved to be effective in exploration and development.
