东营凹陷博兴洼陷深洼区古近系沙河街组三段中亚段沉积特征
|
摘要
利用岩心、测井、录井、地震等资料,应用层序地层学与沉积学理论,建立博兴洼陷深洼区古近系沙河街组三段中亚段层序地层格架,识别沉积相类型,揭示研究区沙河街组三段中亚段湖底扇砂体的充填期次和规律.结果表明:沙河街组三段中亚段地层划分为2个三级层序,层序内部细分为6个体系域;识别湖底扇中扇、湖底扇外扇、深湖3种沉积亚相,以及辫状水道、水道间、席状浊积岩、远源浊积岩和深湖泥5种沉积微相;总结各沉积微相在岩心、测井、地震上的识别特征;在层序格架内识别各体系域沉积相平面展布规律.此研究对该区下一步油气资源的勘探开发具有指导意义.
Based on methods of core observation analysis,using the theory sequence stratigraphy and sedimentology,logging curve comparison and seismic reflection recognition,the sequence stratigraphic framework of the Mid-sha-3 Member,Shahejie formation,Eogene in the deep depression area of the Boxing Sag was built,sedimentary facies types were identified,and the filling periods and filling law of sand bodies of the sublacustrine fan were revealed.The Mid-Sha-3 Member,ShaHejie Formation,Eogene can be divided into 2 third order sequence and 6 system tracts.And 3 sedimentary subfacies including the middle fan of sublacustrine fan,the outer fan of sublacustrine fan and deep lake,and 5 sedimentary micro-facies including braided channel,inter-channel,sheet-like turbidite were identified.And the identification features of various sedimentary micro-facies were concluded in terms of cores,logging and seismic.Finally the planar distribution characters of the sedimentary microfacies of every system tract were figured out in the sequence stratigraphic framework.This study will be helpful for exploration and development of next stage in study area.
