【摘要】 SLG气田是我国重要的低渗透气田,针对性的有效储层预测技术,对增储上产具有重要意义。通过对叠前地震预测方法在SLG地区的实用性进行分析,认为基于测井资料的地震岩石物理分析技术是叠前地震预测方法不可缺少的基础环节,AVO分析技术和叠前地震反演技术是地震预测技术中最为关键的技术。通过实际应用,这些技术在SLG地区取得较好的应用效果,提高气层预测的准确率。更多还原

【Abstract】 SLG is an important low permeability gas field in our country.The prediction techniques aimed at effective reservoir have a great significance for the increase of reserve volume and yield.In this paper,the practicability of seismic prediction techniques in SLG area was analyzed.Based on the research of He 8 sandstone reservoir in SLG area,we considered that techniques of seismic rock physical analysis,AVO forward modeling,prestack seismic inversion,effective absorption coefficient and prestack and poststack seismic property integrated description are key seismic prediction techniques to SLG area.These techniques show good effects on SLG area in practical applications.更多还原
