【摘要】 利用层序拉平法和合成记录标定建立层序地层格架,再结合地震剖面反射特征以及钻井资料识别沉积相,显示该区域内属于辫状河三角洲-湖相沉积体系。在研究区域内S1-2划分出辫状河三角洲平原,辫状河三角洲前缘,前辫状河三角洲,滨湖及浅湖亚相;并通过砂体扫描解释得到沉积相平面图,指出有利储集相带。更多还原

【Abstract】 Based on the sequence level method and the synthetic seismogram calibration to establish the sequence stratigraphic framework, then combined with the characteristics of seismic profiles reflection and drilling data to identify sedimentary facies, and shows that the area belongs to the braided river delta-lacustrine facies sedimentary system. S1-2 sand set is divided into braided river delta plain, braided river delta front and braided river delta, lakeside and shallow lake subfacies.And we can get the horizontal plan of sedimentary facies with sand body scanning solutions, which is conducive to points out the favorable reservoir facies belt.更多还原
