小洼地区洼38井区精细构造解释与储层预测
|
摘要
为寻找洼 38井区新的出油点和储量增长点 ,借助Landmark一体化软件 ,应用相干体分析、可视化、地震属性分析等新技术对其进行研究。通过研究 ,进一步搞清了该区的沉积、构造、储层特征及油气分布规律 ,发现和落实有利圈闭 4个 ;同时指出了下步勘探的方向 :在清东陡坡带应注重断鼻的勘探 ,在潜山披覆构造带上应注重充填沉积体的勘探 ,在冷东逆掩断裂带上应以断块勘探为主
Fine structural interpretation and visualized analysis for the subject reservoir are finished to additional oil reserve in Wa 38 well area at first. Other innovative technologies, including coherence analysis, visualization, seismic attribute analysis, etc., are applied to gain deeper understanding of sedimentary structure, reservoir characteristics and oil/gas distribution regularities at a later stage. Four favorable traps have been identified as result and orientation for next step exploration is established, that is, laying stress on faulted nose in Qingdong steep slope zone, filled up sedimentary body in buried hill drape structures and faulted block in Lengdong thrust fault zone.
