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
Abstract
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.关键词
