东濮凹陷文西斜坡古盐湖沉积的油气储层预测

早第三纪的东濮凹陷是一个典型的盐湖含油气盆地。与传统的“干盐湖”理论沉积模式相比 ,东濮凹陷下第三系沉积组合明显具有砂岩储集层层薄而且少的特点。作者讨论了在高分辨率层序地层研究基础上 ,使用地震岩性反演技术等方法预测东濮凹陷古盐湖沉积超薄储集层分布的实例。在层序地层解释的基础上 ,利用稳定泥岩的区域展布特点 ,使用JASON软件系统的储层反演功能可预测潜在的储集层分布情况 ,追踪含油气砂岩储集层的展布特征 ,预测文西斜坡的储集层展布。

The Reservoir Prediction of Paleo-Saline Sediments in Wenxi Ramp of Dongpu Depression

Dongpu depression in Eogene is a typical oil-bearing saline basin.Compared with the conventional "Sabkha" theoretical sedimentary mode,the strata in the basin has individual features that sandstone reservoir is poor and thin.So reservoir prediction is the most important research work of petroleum geologists.This paper discusses a case that a very thin bed reservoir was predicted with a normal seismic data,which is less thick than that seismic data can resolute, based on the high-resolution sequence stratigraphy interpretation of three-dimensional seismic data,with a composed bed combining stable mudstone(condensed section) and the thin-bed sandstones, and then tracing and mapping the oil-bearing reservoir of the area with JASON lithology inversion.Finally,we predicted the sandstone reservoir in the middle Member Shasan.
