济阳坳陷白垩系沉积特征及其控制因素
|
摘要
济阳坳陷白垩系沉积特征的研究程度较低,使得这一层位的油气资源勘探存在较大风险。在系统观察岩心的基础上,结合测井、地震等资料,对济阳坳陷白垩系沉积特征进行了综合研究,并探讨了沉积的主要控制因素。结果表明,研究区白垩系主要发育的沉积相类型有:杂乱堆积的冲积扇相;纵向上呈粒度向上变细的河流相;中等成分成熟度和结构成熟度的三角洲相;杂色砂泥岩呈薄互层沉积的滨浅湖亚相。北西向断层的活动对沉积起到主要的控制作用,在其控制下,白垩纪济阳坳陷为一相互分割的山间盆地,湖盆范围时大时小,湖水深度不断变化,总体湖水较浅,主要发育滨浅湖亚相。
There exists high risk for oil-gas resource exploration owing to the low study of sedimentary characteristics of Cretaceous in Jiyang depression.According to coring observation,a lot of well logging and seismic data,sedimentary facies types and their distribution in Cretaceous of Jiyang depression were comprehensively studied,and the primary controlling factors were analyzed.The results show that there are many sedimentary facies in Cretaceous of study area,such as alluvial fan with disorderly deposits,river with positive cycle,delta with middling maturity of petro composition and texture,and coastal and shallow lake sub-facies with deposits of thin multilateral mottle sand and shale.Being primarily controlled by northwest faults,Cretaceous of Jiyang depression contained several isolated basins,and lake levels of these isolated basins were instable,but on the whole,shore and shallow lake sub-facies is in the majority.
