利用多元地震属性反演与分析技术综合预测南海M油田有利储层
|
摘要
针对在南海M油田增储上产研究中所面临的砂泥岩难以区分和储层含油性难以判别的问题,在深入研究该区地震、地质、测井等资料和大量模型试验的基础上,选择了高精度拟声波反演、地震衰减分析和多元信息融合等技术,提出了先找储层再判别含油性和融合多种信息减少预测多解性的研究思路,总结出一套利用多元地震属性反演与分析技术综合预测有利储层的方法。该方法在M油田有利储层综合评价中取得了很好的效果。
There are difficulties to discriminate sandstone from mudstone and to evaluate oil potential of reservoir in an attempt to increase oil reserves and to gain production for M oilfield.The data of seismic,geology,logging and a lot of experiments in the field are deeply analyzed,and several techniques are selected,such as pseudo acoustic inversion with high resolution,seismic attenuation analysis and multiple information integration.Based on these,a research idea is developed,that is to look for reservoirs firstly and then to evaluate their oil potential,and to integrate multiple information to reduce prediction ambiguity,and a methodology to use techniques of multiple seismic attribute inversion and analysis for comprehensive prediction of favorable reservoirs is provided.The methodology has made good results in a favorable reservoir evaluation in M oilfield.
