摘要/Abstract

摘要： 四川盆地东北部七里北—渡口河地区飞仙关组具有较大的油气勘探开发潜力,但高频旋回地震识别及追踪难度大,多期次滩体纵向叠置,储层横向非均质性强,未形成配套的迁移型鲕滩储层分期地震预测方法。针对高频旋回地震识别追踪和鲕滩储层分期地震预测难度大的问题,基于不同地震反射相带分区的方法,进行飞仙关组内部旋回横向精细追踪,精细预测飞仙关组多期次鲕滩储层。研究表明:基于不同地震反射相的层序地层地震反射界面追踪对比法,可以有效地解决高频层序界面识别难题,飞仙关组划分出双轴强反射、内部弱反射、单轴强反射、杂乱-亚平行反射和多轴强反射5类反射地震相;利用振幅和弧长敏感属性定性及神经网络反演定量预测成果,明确优质储层主要发育在Ⅱ旋回,从Ⅱ旋回到Ⅲ旋回,储层具有自东向西、从台地向海槽不断迁移进积发育的规律。实践表明,不同地震反射相的层序地层地震反射界面追踪对比,结合敏感属性控制的储层预测方法,针对迁移型鲕滩储层具有较好的适用性。该研究对同类型气藏储层精细预测具有一定的借鉴意义。

Abstract: A large potential for oil and gas exploration and development is found at the Feixianguan Formation in the Qilibei-Duokouhe area of the northeastern Sichuan Basin, but the high-frequency rotary seismic identification and tracking are difficult, the multi-stage beach body is vertically stacked, and the reservoir has strong lateral non-homogeneity, so a supporting staged seismic prediction method for the migratory oolitic beach reservoir has not been formed. In response to the difficulties of the high-frequency rotary seismic identification and tracking and the staged seismic prediction of oolitic beach reservoirs, the horizontal fine tracking of internal cycles in the Fixianguan Formation was carried out on the basis of the method of zoning different seismic reflection phase zones, to make a fine prediction of multi-stage oolitic beach reservoirs in the Fixianguan Formation. The study shows that the seismic reflection interface tracking and comparison method for the sequence stratum based on different seismic reflection phases can effectively solve the problem of identifying the interface of high-frequency stratigraphic sequences, and the Fixianguan Formation has been divided into five types of seismic reflection phases: biaxial strong reflection, internal weak reflection, uniaxial strong reflection, cluttered-subparallel reflection, and multiaxial strong reflection; the results of the qualitative prediction of amplitude- and arc length-sensitive attributes and the quantitative prediction of the neural network inversion make clear that the high-quality reservoirs mainly develop in the The results of the quantitative prediction using amplitude and arc length sensitive attributes and neural network inversion showed that the high-quality reservoirs are mainly developed in the Cycle Ⅱ, and from the Cycle Ⅱ to the Cycle Ⅲ, and the reservoirs have the pattern of migrating and accumulating from the east to the west, and from the plateau to the trough. The practice has shown that the seismic reflection interface tracking and comparison method for the sequence stratum of different seismic reflection phases, combined with the reservoir prediction method controlled by sensitive attributes, is suitable for the migratory oolitic beach reservoir. This study is also useful for the fine reservoir prediction in the same type of gas reservoirs.
