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。
According to the DSI logging data of 60 wells in Junggar Basin and the acoustic time-difference and density logging data of more than 150 wells, the statistical analysis of the longitudinal and shear wave velocities and densities of water-bearing sandstone, oil-bearing sandstone, gas-bearing sandstone and mudstone, The law of variation of rock elasticity with depth is obtained. The seismic reflection characteristics of oil and gas sandstone in Junggar Basin with depth variation are further analyzed. At the same time, the AVO subsidence caused by the combination of calcareous mudstone strata is found out. The application of forward model to gas production in Well Hu 2 was analyzed and verified by AVO technology, which was consistent with the analysis results.
