摘　　要：为解决济阳坳陷中深层气藏由于埋藏深、地震资料品质不理想及单一的储层预测技术应用效果差的问题,在系统分析沉积相对烃源岩、储层分布、储盖组合和储层物性等控制作用的基础上,开发了基于相控的生储盖地震地质综合解释技术,结合相势匹配关系,建立了中深层气藏的相控模式。该技术丰富了中深层气藏勘探的技术方法,在孤北深层天然气藏的预测中取得了良好的效果,可以作为济阳坳陷中深层气藏勘探的有效手段。The application effect of single reservoir prediction technology is poor in mid-deep gas reservoirs of Jiyang Depression because of worse quality of the seismic data and deep buried depth.On the basis of systematical analysis on the control of sedimentary facies to the source rocks,reservoir distribution,association of reservoir and cap rocks,reservoir physical property,etc.,seismogeology integrated interpretation technology of source bed-reservoir-cap rock has been produced based on facies control.The facies control pattern of the mid-deep gas reservoirs is set up associating with the facies-potential matching relationship.The usage of this technology has obtained good effect on the gas reservoir forecasting in Gubei deep zone in Jiyang Depression.It enriches the technical method of the mid-deep gas reservoir exploration,which is suitable to the available exploration means in Jiyang mid-deep gas reservoirs.
