摘要
冷家-雷家地区位于辽河坳陷西部凹陷中段,根据高分辨率三维地震资料,精细解释断层和断裂系统,确定了地层层位和局部构造,分析了圈闭特征。研究区受北东向主干断裂控制,形成陈家洼陷、背斜构造带、斜坡带三个二级构造带。该区断裂构造发育,断层活动复杂,含油层系众多,油藏类型多样。研究表明构造变形是油气聚集的关键因素,断裂、背斜构造的发育对盆地内沉积相带发育和生、储、盖及油气藏的分布具有重要的控制作用,构造地质条件的研究在油气勘探的全过程中至关重要。
Lengjia-Leijia area is located in middle part of Liaohe western depression.According to high resolution three dimensional seismic data,fine interpretation of fault and faulty system,stratum position and local structure has been determined and the trap characteristic has been analyzed.The study area is controlled by north east main fault,and is formed with three secondary structural belts of Chengjia fault sag,anticline belt and slope belt.This area faulted structure developed,the fault activity is complex,the oil-bearing stratum is numerous,the oil deposit type is diverse. The research indicated that the tectonic deformation is the key factor of oil and gas accumulation,the fault,anticline tectonic development plays important role in basin sedimentary facies belt development and source,reservoir,seal rock and distribution of hydrocarbon reservoir.The geotectonic condition research is vital importance in the entire process of oil-gas exploration.
