河套地区呼和坳陷第四系更新统地震相与沉积相
|
摘要
河套地区呼和坳陷生物气勘探已经成为长庆油田寻找后备储量的新领域。目前,该区生物气勘探研究程度低。本文主要利用地震反射波的振幅、连续性、内部结构和外部形态等地震反射特征,在第四系更新统的地震反射中识别出了3种地震相类型:中—强振幅连续反射平行—亚平行席状地震相、变振幅断续及较连续反射平行—亚平行席状地震相以及杂乱地震相。编制了研究区地震相平面分布图,同时利用单井资料对和1、和5井进行了单井沉积相分析。经综合分析,将地震相转变为沉积相,认为本区主要发育浅湖、半深湖、滨(浅)湖等沉积相,该项研究将对本区后续的生物气勘探起到一定的理论指导作用。
The exploration of biological gas in the Huhe Depression of the Hetao area has become the new domain of searching reserves while the exploration degree of biological gas is relatively low.According to the characteristics of seismic reflection such as amplitude,continuity,interior configurations and exterior shapes,three types of seismic facies are recognized on the seismic reflections of the Pleistocene in this area,including medium-intense amplitude continual paralleling or sub-paralleling sheet facies,variable amplitude weak-continuity and medium continuity and paralleling or sub-paralleling sheet facies,disorderly facies.Furthermore,the distribution map of seismic facies has been compiled for the Huhe Depression,and the sedimentary facies of wells He 1 and He 5 have been analyzed using the core data.In the end,the seismic facies have been transferred into sedimentary facies,and the results show that the shallow lake,semi-deep lake and shore lake sub-facies were mainly developed in the study area.It is no doubt that this research will have a guiding effect on the exploration of biological gas in this area.
