摘　　要：松辽盆地北部齐家地区高台子油层发育典型的致密砂岩油储层,需通过水平井的钻探有效动用致密油资源.针对致密油“甜点”的井间分布预测和水平井钻探设计需求,提出了相对保幅的高分辨率处理、地震岩石物理分析、叠前AVO反演及“甜点”识别等系列地震技术,有效支撑了该区水平井钻探.地震综合预测技术具有良好的应用前景。The typical tight sandstone oil reservoirs are developed in Gaotaizi oil layers in Qijia region of North Songliao Basin,the tight oil resources must be effectively developed by horizontal exploring well.In the light of the requirements of predicting the interwell distribution of the ＂sweet spot＂ and design of the horizontal well,a series of seismic techniques are proposed such as high-resolution seismic processing with relatively preserved amplitude,seismic petrophysical analysis,prestack AVO inversion,＂sweet spot＂ discrimination and so on,all these achievements effectively support the horizontal well drilling in the region.The seismic integrated predicting techniques possess much better application prospects.
