| 中文摘要: |
| 多点地质统计学是一种建立地质模型的方法，该方法比传统的两点地质统计学更适合河流相沉积体系。本文基于地震、测井、录井及生产数据，绘制了苏48区块的盒8下段辫状河训练图像，并在此基础上利用多点地质统计学方法，加入三维地震资料作为约束，以水平井整体开发为研究对象，建立了该区的地质模型，优化了水平井整体部署，指导水平井导向。利用多口水平井实钻效果验证了地质模型的精度，以苏19-62井为例，录井显示气层钻遇率为78.3%，测井显示气层钻遇率为69%。这与地震反演剖面预测相似，且与实钻效果有很好的对应性。 |

| The multiple-point geostatistics is a useful tool for geological modeling, which is more suitable for fluvial sedimentary systems than the traditional two-point geological statistical method. Using data from seismic survey, logging and production, this work has plotted the training images for the braided streams in the lower section of He 8 in the Su48 block. training image. Then we constructed a geological model for this area using the multiple-point geostatistics with 3D seismic data as constraints and whole development of the horizontal-well area as the target. The establishment of this geological model permitted to optimize the horizontal-well deployment and to guide horizontal-well orientation. Real drilling results verify the accuracy of the geological model by using multiple horizontal wells. As exemplified by the Su 19-62 well, the well log displays a gas-reservoir drilling ratio of 78.3%, and logging shows a reservoir drilling ratio of 69%, which are similar to prediction of seismic inversion profiles and correspond well to the real drilling results. |
