焉耆盆地宝浪油田宝中区块波阻抗反演储层预测

摘要

The inversion technique of wave impedance has successfully been employed in the prediction of eight reservoir sandstone beds within the Baozhong block, Baolang oil field, Yanqi Basin, Xinjiang. The technique is mainly developed on the basis of well logs, especially the constraints on the well logs. Therefore the results of inversion obtained have higher resolution and reliability. The distribution of sandstone bodies may well be delineated with the aid of this method, and thus the risks on exploration and exploitation may be decreased to the least degree.%笔者采用波阻抗反演技术，对新疆焉耆盆地宝浪油田宝中区块8个小层的砂体厚度进行了横向预测。该方法的关键在于对测井资料的应用，也就是测井资料的约束条件，使得反演结果具有较高分辨率和可靠性。通过预测，认清了该区块砂体从上至下的分布规律，克服了“一孔之见”的缺陷，增强了预见性，减少了风险性，为编制开发方案奠定了基础。
