摘要
针对河道砂体横向变化较快的非均质性特点,通过对低频信息保存较好的地震纯波进行信息挖潜,提取纯地震振幅信息以及相对阻抗反演进行河道砂体预测,利用地震低频增量属性对流体进行预测,有效解决了河道砂体横向变化较快的横向非均质性难题。通过河道砂体及流体检测结果,进行井位部署的优选,提供建议井5口,其中4口获得高产,研究结果可以作为油田生产井位部署的主要依据,此研究方法可以在类似地质条件区块中加以推广应用。
According to the characteristics of the lateral heterogeneity geological changes of channel sand body, this article uses the pure seismic information, in which low frequency information is well preserved, to predict the sand body and fluid by extracting pure seismic amplitude information by doing relative impedance inversion and using the low-frequency incremental attribute. According to the prediction results of sand body and fluid, well location optimization can be performed. Five wells were suggested and four of them had high yields. The research result can be used as a basis for the next step of the production of the oil field well deployment, and it also can be popularized in similar geological conditions blocks.
