【摘要】 针对临盘油田大芦家地区馆三段构造高点不清和成藏规律认识不清的矛盾,本文在前人工作的基础上,综合利用地质、测井和地震资料,利用高分辨率层序地层学分析、综合层位标定技术、相干数据体分析技术、可视化技术以及低序级断层识别技术等多种新技术与方法,对该区进行了精细构造解释;在精细地层划分和对比的基础上,通过补心,海拔及井斜的校正,做出了研究区的3幅顶微构造图。对各小层的顶面进行了构造特征分析,指出了剩余油富集的有利地区。更多还原

【Abstract】 For the ambiguity of structural high and reservoir-formation rules in the third section of Guantao formation of Dalujia tectonic block in Linpan oilfield,based on the summarization of predecessors’ work,this paper synthesizes geologic information、logging、seismologic data and some new methods and techniques such as high resolution sequence stratigraphic analysis、integrative layer-labeling technique、coherent data volume analysis、lower-order faults identification technique etc are used to study the fine structure and reservoir-formation rules in the researched area.On the basis of the fine stratigraphic division and correlation,according to make adjustment of well deflection、above sea level of well-head and bushing elevation,completing three top micro-structure graph.Analyzing the tectonic properties for the top surface of each single sandstone layer,pointing out the favorable area of the residual oil concentration.更多还原
