摘    要:以吐哈盆地温米油田含油层段为例,探讨在陆相油田开发阶段进行油藏范围内高分辨率层序地层学研究的方法和技术.提出了一种综合应用岩心、测井及测井约束地震反演资料进行湖泛面识别和对比的新方法.通过岩层组合关系、自然伽马及自然伽马能谱测井、岩矿分析和X衍射分析,对工区低伽马泥岩的成因及其层序地层学意义进行了研究.研究表明,低伽马泥岩是在湖泛时期由于富含放射性的钾长石和云母等矿物受到抑制而沉积形成的,因此,低伽马泥岩可作为湖泛面识比的标志.应用测井约束反演资料,可对湖泛面及高分辨率时间地层单元进行高精度的追踪对比.据此,建立了温米油田三间房组含油层段(高位体系域)的高分辨率时间地层单元格架,从而为储层流动单元及渗流屏障的研究奠定了基础.

关 键 词:高分辨率  层序地层学  自然伽马测井  测井约束反演  温米油田  侏罗系  油藏开发

Abstract:Taking the oil bearing series of Wenmi Oilfield in Turpan Hami Basin as an example,this paper has studied the techniques and methods for high resolution sequence stratigraphical research within reservoir in terrestrial oilfield in development stage.A new method was proposed that recognition and correlation of flooding surfaces and chronostratigraphic units through the integration of cores,well logging and well logging constrained seismic inversion data.Through the comprehensive analysis of formation relation,natural gamma ray logging data,gamma ray spectrometric data,petrology and x ray diffraction,the origin and sequence stratigraphic significance of the low gamma shale were studied.The results show that the low gamma shale was deposited in the lake flooding stage which inhibited the deposition of minerals with high radioactivity such as k feldspar and mica,so the low gamma shale may be referred as the recognition marker of flooding surfaces.The correlation of flooding surfaces and high resolution chronostratigraphic units can be made using well logging constrained seismic inversion data.Based on this,a high resolution chronostratigraphic framework of oil bearing series of the Sanjianfang formation in Wenmi Oilfield was built,which provides the basis of research of reservoir flow units and percolation barriers.
Keywords:ywords:high resolution  sequence stratigraphy  natural gamma ray logging  well logging constrained seismic inversion  Wenmi Oilfield  Jurassic  reservoir development
