摘　　要：随机地震反演方法是一项用于油田开发区块 ,提高储层描述精度及油气识别的重要技术。利用地质统计模拟与地震反演紧密结合完成的随机地震反演处理 ,可以得到多种地下目的储层的岩石物性参数分布特征 ,其分辨能力具有同时兼顾薄储层及厚储层的优点。在埕北 35井北地区的成功应用表明 ,该方法许多处理环节具有独特的技术特点和要求 ,通过对这些技术的有效控制和应用 ,取得的反演结果可以在储层描述、储量计算。Random seismic inversion is an important technique that can be used for oilfield development and to improve the precision of reservoir description and oil gas identification.Closely combining the geostatistical modeling with seismic inversion to complete the random seismic inversion can result in distributing characters of petrophysical parameters that the variety of underground objective reservoirs has,which the resolution has the advantage of considering both the thin reservoir and the thick reservoir.Successfully used this method in Chengbei No.35 well zone showed that the many processing steps of the method have its particular characters and demands,the resulted inversion from effective controlling and application of these techniques can play an important role in reservoir description,reserve calculation and drawing up the development plan.
