【摘要】 利用高分辨率层序地层学理论和技术方法,综合岩心、地震和测井小波资料,对印度尼西亚南苏门答腊盆地Jabung区块NEB气田Lower Talang Akar段Lumut亚段地层进行高分辨率层序地层学研究,从中识别出长、中、短3个级别基准面旋回,以各中期层序的上升和下降相域为编图单元,讨论Lumut亚段高MSC1～MSC3中期层序上升、下降半旋回相域的岩相古地理特征。更多还原

【Abstract】 Based on integrating well wavelet and seismic data,in combination with high resolution sequence stratigraphic theory and techniques,the marine delta sedimentary system of Lower Talang Akar Formation in NEB Gas Field of Jabung Block in the South Sumatra Basin was divided into short-term,middle-term and long-term base-level cycles.The base-level cycles of different orders are correlated with the restriction of seismic interpretation and method of cycle isochrostratigraphy correlation.The ascending and descending half-cycle facies tracts of each middle-term sequence system are taken as the mapping unit,the lithofacies paleographic characteristics of each ascending and descending half-cycle facies tract of MSC1-MSC3 are plotted and discussed.更多还原
