摘要
针对辽河坳陷东部凹陷西斜坡北部铁匠炉—大湾斜坡带构造演化复杂、地层结构复杂、储层变化大等地质特点,综合运用层序地层学、古地貌分析、“三相”联合解释、地震属性预测砂体分布、分频解释和多参数反演等技术,对本区沙三段岩性油气藏有利储层、储盖组合、岩性圈闭发育区、油气运聚条件等进行分析预测,有效地预测沙三段碎屑岩有利储层的分布状况,实现了该区岩性油气藏勘探的重大突破,对开展岩性油气藏研究具有指导意义。
Tiejianglu-Dawan slope belt in the north of the west slope,eastern sag,Liaohe depression is sophisticated in tectonic evolution,formation structure,and shows big difference in reservoirs.This paper uses sequence stratigraphy, palaeogeomorphic analysis,'three-phase' interpretation,sand distribution prediction by seismic attribute,frequency division interpretation and multi-parameter inversion to analyze and predict favorable reservoirs,reservoir-caprock association,lithologic trap development zone,and oil and gas migration and accumulation conditions of s_3 lithologic reservoirs in this area.The distribution of s_3 clastic reservoir has been effectively predicted.This is a big breakthrough of lithologic reservoir exploration in this area and may guide the study of such reservoirs.
