孤东地区馆陶组河道砂体油藏勘探技术研究

The technology research on riveralsands reservoir exploration of Guantao formation in Gudong area

孤东地区馆陶组为河流相沉积体系,河道砂体岩性圈闭发育,为典型的隐蔽型岩性砂体油藏。因此,加强河道砂体的识别描述和评价研究,才能实现孤东地区河道砂体勘探的新突破。本文针对孤东地区馆陶组地质特点,以高精度三维地震资料为基础,形成了"水平切片、测井约束反演、地震属性分析、三维可视化和油气检测评价"等勘探技术。河道砂体识别描述技术的综合研究,对指导孤东地区馆陶组河道砂体勘探具有重要的作用。

Guantao formation is riveral depositional system in Gudong area,riveralsands lithologic trap development,it is a typical sandstone reservoir lithology concealed type,therefore,strengthen the channel sandbody identification description and evaluation studies can be achieved riveralsands exploration breakthrough in Gudong area.In this paper,to the geological characteristics of Guantao in Gudong area,base on high-precision three-dimensional seismic data,the formation of a ＂horizontal sections,logging constrained inversion,seismic attribute analysis,three-dimensional visualization and evaluation of hydrocarbon detection＂ and other exploration techniques,riveralsands identification techniques described in a comprehensive study has an important role to riveralsands exploration of Guantao formation in Gudong area.
