Reservoir Prediction of J2x Gas Reservoir in Qiudong Gas Field

通过针对吐哈盆地台北凹陷侏罗系西山窑地层扇三角洲储层沉积特点,利用相关分析技术软件及解释,获得了西山窑组各主砂体地震均方根振幅属性、平均振幅属性和地震相分类属性,定性预测了砂体分布特征;采用Emerge神经网络多属性预测技术,对该区储层进行单砂体级别的定量预测描述;圈定了有利储层位置,提出了3口调整井井位,应用效果良好。

According to deposit characteristics of fan- delta of Jurassic J2x stratum in Taibei depression in Thuha basin, using coherent analysis technical software and interpretation, seismic root- mean -square amplitude attribute and average amplitude attribute as well as seismic facies classification of main sand bodies of J2x formation are obtained, the distribution characteristics of sand body is quantitatively predicted. Using the technology of Emerge neural network multi - attribute prediction, single sand body of reservoir in the region is quantitatively predicted and described, preferential reservoir is located, and three adjustment wells location is given, with good application effect.
