饶阳凹陷武强地区新生代断裂构造特征及其控藏作用
|
摘要
渤海湾盆地饶阳凹陷武强地区新生代断裂构造发育,并对烃源岩、沉积、储层及油气运聚成藏具有重要控制作用。为此,结合钻井、测井等基础地质资料,利用三维地震数据体系统分析了饶阳凹陷武强地区的断裂构造特征,并深入探讨了新生代断裂活动对油气成藏的控制作用。研究结果表明:饶阳凹陷武强地区主要发育非旋转平面式、旋转平面式、铲式及坡坪式4种类型正断层,纵向上多呈断阶型、"y"字型或反"y"字型、"马尾"状及堑垒状等组合形式,平面上多呈雁列式展布;该区新生代共发育孔店组-沙四段(强烈断陷期)、沙三段-沙二段(湖盆扩张期)、沙一段-东营组(抬升剥蚀期)3期断裂体系,且以前两期为主,第3期为抬升剥蚀期,断裂活动微弱;前两期断裂活动是武强地区富烃洼陷形成及两套主力烃源岩发育的重要因素,且断裂活动对研究区的古地貌特征、沉积体系与储集砂体的空间展布亦具有显著的控制作用。基于上述研究成果,认为武强地区断裂活动控制油气成藏的整个过程,不同区带油气成藏分布规律具有明显的分隔性和差异性。
The Cenozoic fault system developed in the Wuqiang area of the Raoyang sag plays an important role in controlling the source rocks,sediments,reservoir formation and hydrocarbon accumulation and accumulation processes. This paper,combining with the basic geological data such as drilling and logging,analyzes the characteristics of this fault system using 3 D seismic data system,and discusses the control effect of Cenozoic fault system on hydrocarbon accumulation in Wuqiang area of Raoyang Sag,Bohai Bay Basin.The results show that the Wuqiang area of Raoyang sag mainly develops four types of normal faults: non-rotating plane type,rotating plane,shovel type and sloping type. The longitudinal direction is mostly fault-type, "y"-shaped or anti-.The combination of "y" type, "horse tail" and combination of the base appears on the plane. During the Cenozoic period,a three-stage fault system was developed in the Kongdian-Es_4 section(strong fault depression period),the Es_3-Es_2 section(lake basin expansion period),and the Es_1-Dongying Formation(lifting and erosion period). Mainly,in the third period of uplifting and erosion,the fault activity tends to be weak. The second-stage main fault system is an important factor for the formation of hydrocarbon-rich depressions and the development of two main source rocks in Wuqiang area,and the fault activity also has the paleo-geomorphological characteristics of the study area,the sedimentary system and the spatial distribution of the reservoir sand bodies, showing significant control. The above characteristics and analysis suggest that the fault process in Wuqiang area controls the whole process of hydrocarbon accumulation,and the distribution rules of hydrocarbon accumulation in different zones have obvious separation and difference.
