东营凹陷浊积岩优质储层预测技术
|
摘要
针对东营凹陷浊积岩油气藏"埋藏深、个体小、厚度薄和含灰质"的特点,建立了浊积岩优质储层预测技术。该技术主要包括三个部分:1利用子波分解技术对地震资料进行保幅拓频处理,可以有效提高浊积岩发育层段地震资料分辨率和保真度;2利用高精度古地形恢复技术、地震属性技术和波阻抗反演技术对浊积岩储层有利发育区进行宏观预测;3综合使用多参数岩性反演技术、高亮体地震属性技术、甜心体地震属性技术和叠前反演技术,能够有效区分浊积砂岩与含灰质砂岩、灰质泥岩。该技术在东营凹陷及梁家楼地区的应用中取得了良好效果。
Turbidite reservoirs in Dongying Depression are characterized by deeply buried small bodies and thin limestone.To solve the problem,we propose an approach for high-quality reservoir prediction on seismic data.The approach includes three parts:1Frequency broadening with wavelet decomposition for resolution and fidelity improvement;2Turbidite zone macro prediction with high accuracy palaeo- geomorphology resume,seismic attributes and impedance inversion;3Sandstone identification from mudstone and limestone with multi-parameter lithology inversion,high light body attribute,sweetness body attribute,and prestack attributes.Rather good results are obtained by the proposed approach in Bindong and Liangjialou areas,Dongying Depression.
