摘要

利用常规地震反演进行储层预测,影响因素诸多。而随机反演将随机模拟技术与常规地震反演相结合,有效地综合地质、测井和三维地震数据,可以弥补井点资料的不足,提高预测精度,在滚动开发阶段可以起到积极的作用。利用随机反演对某地区三维工区Eq41、Eq42、Eq43层段的渗透性砂岩进行预测,取得了较好的效果。
The application of the conventional seismic inversion in reservoir prediction is constrained by many factors, while the technology of random inversion combines effectively the random simulation technology and conventional seismic inversion, and integrates geology、logging and 3-D seismic data, which can make up for the lack of enough information about logging and improve prediction accuracy, what is more, this technology can play a positive role in the rolling stage of exploitation. The technology was applied in a three-dimensional work area to predict permeable sandstone in layers Eq41, Eq42and Eq43, which achieves good results and plays a positive role in the rolling stage of exploitation.
