摘要
根据准噶尔盆地60口井的DSI测井资料和150多口井的声波时差、密度测井资料，对其中的含水砂岩、含油砂岩、含气砂岩和泥岩的纵、横波速度及密度的统计分析，得出了研究区岩石弹性参数随深度变化的规律。进一步分析出准噶尔盆地含油气砂岩随深度变化的地震反射特征，同时发现了由含钙泥岩地层组合造成的AVO陷阶。对呼2井产气层做了正演模型应用分析，并用AVO技术进行了检测验证，与分析结果一致。
Based on DSI logging data from 60 wells and transit and density logging data from more than 150 wells in Junggar basin, this paper launched a statistical analysis of P-and S-wave velocity and density of water-bearing sandstone, oil-bearing sandstone, gas-bearing sandstone and shale, and then realized the variation of rock elastic parameters with depth. Moreover, the seismic reflection characteristics of hydrocarbon-bearing sandstone with depth in Junggar basin were sununarized, and AVO pitfall resulting from the combination of calcareous mudstone found.The forward modelling of gas producing pay in Well Hu2 was in good agreement with AVO measurement.
