| 摘 要： | 准噶尔盆地南缘山前构造复杂,油气勘探潜力大.高探1井获得高产油气流,高泉背斜目的层埋藏深、小断裂发育、储层薄,地面地震采集资料分辨能力非常有限.为此,开展了 Walkaway VSP(W-VSP)技术攻关,实施了三条W-VSP三分量资料采集.资料对比分析表明,W-VSP资料分辨率明显高于地面地震,能够较清楚地识别小断裂...

| Abstract: | The piedmont structures at the southern margin of the Junggar Basin are complex,with great oil-gas exploration potential.Well GT1 has achieved high-yield industrial oil-gas flows.In contrast,the target formations of the Gaoquan Anticline are deeply buried,the reservoir is thin,and small faults have developed.Consequently,surface seismic data has a limited resolution.In response,efforts are made to achieve technical breakthroughs in walkaway vertical seismic profile(W-VSP).Three-component W-VSP data are collected.Comparative data analysis shows that the resolution of W-VSP data is significantly higher than that of the surface seismic data and small faults and thin reservoirs are thereby clearly identified.This research not only provides a basis for analyzing the distribution of main oil-gas target formations and the types of oil-gas reservoirs of the Gaoquan Anticline but also offers experience for W-VSP application at Xinjiang Oilfield. |
