摘要: 江陵凹陷南斜坡古近系新沟嘴组下段岩性岩相变化大,储层厚度薄,岩性圈闭的识别难度大。此次针对凹陷南斜坡金家场三维区,以古地貌与成藏分析为基础,以砂组或单砂层为单元,以薄互层砂体预测为核心,以地震地质复合微相为指导,建立了一套利用地震地质复合相控和地质统计学反演相结合的薄互层砂岩储层预测技术,开展了南斜坡地区的砂岩展布规律预测,为江陵凹陷新领域的油气勘探提供指导。

Abstract: The lower Xingouzui Formation of the southern Jiangling Depression is characterized by interbedded thin reservoirs, that make the lithological traps quite difficult to be identified. Taking the 3D surveyed area in the Jinjiachang of the southern Jiangling Depression as an example, we worked out a set of prediction techniques for thin-interbedded sandstone reservoirs, which include both seismic and geological composite phase control and geostatistical inversion on the basis of paleogeomorphy and reservoir formation mechanism under the guidance of seismic and geological composite microfacies. The sandstone distribution pattern is revealed on the south slope of the Jiangling Depression.
