摘要
埕南大断层下降盘发育了许多不同规模的砂砾岩体。本文应用三维可视化技术、地震属性技术、相干分析技术对砂砾岩扇体的时空展布进行了分析研究和预测 ,采用测井约束反演技术、时频分析技术对单个砂砾岩扇体进行了描述 ,确定出研究区古地貌的 6个古冲沟及其对应的埕 913等 10余个砂砾岩体的空间展布特征 ,初步形成了砂砾岩体储层预测及描述技术序列 ,实现埕南断裂带上砂砾岩扇体油藏的高效勘探开发 ,取得了显著的勘探效果。
There are many scale-different sand-gravel body that developed in downdropped block of Chengnan great fault.The paper used 3-D visualization technique,seismic attributes technique and coherent analysis technique to analyze and predict the time and space distribution of sand-gravel fans,used logging-constrained inversion technique and time-frequency analysis technique to describe the single sand-gravel fan and determined the space distributed feature of 6 paleo-gulches of palaeogeomorphology in the study area and their corresponding more than 10 sand-gravel bodies such as Cheng 913 etc.,preliminary forming the predicting and describing series of sand-gravel body,that realized high-efficient exploration and development of sand-gravel fan reservoir and resulted in good exploration benefits.
