摘　　要：以新疆吐哈盆地温米油田为例 ,探讨应用测井约束地震反演资料进行高分辨率时间地层单元对比的思路和方法。研究表明 ,由于测井约束反演不仅可提高原始地震资料的垂向分辨率 ,而且可将地震波转换为层的信息 ,因此 ,据此可进行高精度的时间地层单元的追踪对比。在油田开发阶段 ,应用测井约束反演资料进行高分辨率等时地层对比的步骤包括 :地震资料的时 -深转换 ;应用地质、测井、地震资料建立宏观层序地层格架 ;测井约束地震反演处理 ;测井细分层及标定 ;This paper, taking the Wenmi (Wenjisang—Mideng) Oilfield of the Tuha Basin as an example, discusses the methods of high resolution correlation of time stratigraphic uints using logging constrained seismic conversion data. This kind of conversion not only can increase the vertical resolution of seismic data, but also make the seismic waveform data to be transformed into zone data. Therefore the conversion data can be used in high resolution correlation of time stratigraphic uints. The correlation steps proposed includes: (1) time depth transform of seismic data; (2) creation of large scale sequence stratigraphic framework according to the integration of geologic, well logging and seismic data; (3) logging constrained seismic conversion processing; (4) well logging interpretation of geological layers and log to seismic calibration; (5) tracking and correlation of time stratigraphic uints in well logging constrained seismic conversion section.
