摘　　要：准噶尔盆地南缘前陆冲断带勘探潜力巨大,但特殊地震地质条件造成地震资料品质普遍较低,影响了构造圈闭识别的准确性,对南缘油气发现影响巨大。采用GeoEast系统高保真去噪技术、DIVA井控建模技术、复杂构造建模技术等处理解释一体化技术序列,大幅度改善了齐古背斜地震资料成像品质,提高了高陡构造成像精度,深度域成像与井深相对误差控制在2.5%以内。GeoEast处理解释一体化系统特色技术为地质研究提供了可靠的基础资料,有力支撑了该地区井位部署与论证。Foreland thrust belts in the southern margin of Junggar Basin have great potential for the hydrocarbon exploration,but seismic data quality is rather poor due to surface conditions,which affect greatly the structural trap identification and hydrocarbon discoveries in the area.To overcome the problems we adopt a series of integrated processing and interpretation approaches provided by GeoEast such as high fidelity denoising,DIVA well-control modeling,complex structure modeling,etc.Both seismic data quality and steep structure imaging in Qigu Anticline are greatly improved.The depth difference between our predicted targets and that found by drilled wells is less 2.5%.The integrated processing and interpretation technology of GeoEast provides reliable basic data for geological research and effective supports for the future deployment in this area.
