摘要
在我国东部地区,针对老油气区开展精细勘探,具有十分重要的战略意义。文中以松辽盆地徐家围子地区葡萄花油层为例,系统论述了老油区精细勘探的思路及方法。首先在纵向上细化研究目的层,综合利用地震储层反演和测井相分析结果,开展大比例尺沉积微相研究,搞清目的层段储层的时空展布规律,在此基础上叠合三维地震精细构造解释成果,以岩性油气藏评价的思路进行分析,最终在勘探老区取得了很好的勘探效果。
With the exploration difficulty increasing, the fine exploration becomes more and more important to the oilfields, especially the eastern old oilfields in China. The authors analyzed the method of the fine exploration in the old oilfields based on the research of Putaohua Formation in Xujiaweizi area, Songliao Basin, divided the targets in vertical direction, and carried out sedimentary microfacies study to make clear the distribution of the target reservoir by using seismic reservoir inversion and logging facies analysis. By overlapping 3D fine structural map and reservoir distribution map, the targets were synthetically analyzed according t6 the lithologic reservoirs exploration method, which proved a good exploration effect.
