英买力地区复合潜山的地层分布及意义

英买力地区复合潜山构造非常复杂,采用地震相与地震多属性聚类分析技术时潜山不同岩性进行了识别和有效区分,明确了白垩系下伏地层的分布范围和意义,特别是侏罗系的分布直接导致潜山油气的漏失.同时利用地震多属性聚类方法对复合潜山储层发育进行预测,有利储层主要分布在上寒武统白云岩潜山、英买7以北下奥陶统灰质云岩潜山以及志留系柯坪塔格组沥青砂岩段.

Stratigraphic distribution of complex buried hill and its significance in the Yingmaili aera

In order to determine the stratigraphic distribution of a complex buried hill composed of different rocks, subtly structure elucidation is made on the condition of complex tectonic setting based on technology of seismic facies analysis and seismic muti-attribute clustering. It is very important to know stratigraphic distribution along the Cretaceous bottom, especially Jurassic distribution leads to the breakage of buried hill hydrocarbon reservoir. Then revervoir distribution of the complex buried hill is predicted by use of the seismic muti-attribute clustering analysis method. The results obtained suggest that favorable reservoir is distributed on the upper Cambrian dolomite buried hill and lower Ordovican grey matter dolomite buried hill north of the Ym7 well, as well as bitumen-bearing sandstone member in the Kepingtage formation of Silurian.
