摘要/Abstract

摘要： 以准噶尔盆地西北缘五区南油藏上二叠统乌尔禾组为实例，用二维地震资料进行油藏描述。以油藏框架描述为基础，从工区中选出26条过井多、质量高的二维地震剖面，在斯伦贝谢公司的CHARISMA和CGG公司的INTEGRAL勘探工作站上进行了精细的解释，并综合应用地震、测井、钻试和分析化验等资料描述构造、地层沉积、横向追踪油气层、反演绝对波阻抗剖面和孔隙度剖面，研究孔隙度平面变化，利用地震多种信息和绝对波阻抗剖面确定气油界面和油水界面。研究所得出的结论与钻探结果是符合的，说明在准噶尔盆地西北缘用二维地震资料进行精细油藏描述是可行的。

Abstract: With respect to Wuerhe formation reservoir (Upper Permian), south District No.5 in northwest margin of Junggar basin, the reservoir description has been made with 2~D seismic data.Based on the reservoir framework description, 26 high-quality 2-D seismic profiles which travel through more holes have been selected in work area, the fine interpretation has been made on CHARISMA (Schlumberger Co.) and INTEGRAL (CGG Co.) exploration workstations.The data of seismic, logging, drill stem testing, and lab analysis were wholly used to undergo the structure and sedimentology description, lateral tracing of oil and gas bed, backward modelling of absolute wave impedance and porosity profiles, and studies in change of porosity in plane.Gas/oil contact and oil/water contact were determined by using varied information of seismic event and absolute wave impedance profile.The agreement between the above results and drilling results suggest that the fine reservoir description with 2 D seismic data in northwest margin of Junggar basin is feasible.
