地震沉积学在渤海蓬莱油田中的应用研究
|
摘要
综合该区地震、地质及测井资料,结合层序地层学理论和钻井沉积相分析,利用地震沉积学的90°相位转换技术和地层切片技术,重新建立该区的等时地层格架,开展储层平面展布研究。研究结果表明,在等时地层格架下划分的油组小层更符合油田生产动态,能有效指导油田注采井网调整;在岩心和测井资料基础上,结合地层切片属性分析该区储层平面展布规律,提出该区馆陶组为辫状河三角洲沉积体系。
This paper focuses on the research of reservoir sand distribution based on the reconstruction of the time equivalent framework in this area,which is closely related with comprehensive geological,seismic and logging data,and integrated the theory of sequence stratigraphy and sedimentary facies analysis,using the major technology 90°phase transform and strata slicing of seismic sedimentology. The research showed sub-layers of different oil group which using the time framework picked can match the dynamic data well and it can effectively guide the field injection and produce well pattern adjustment. It also proposed the new understanding that depositional system of Guantao formation is a braided-river delta,based on the coring and logging data and analysis of the regularities of distribution of reservoir sand,integrated with the strata slicing attribute analysis in this area.
