摘要(Abstract)：

受分辨率和薄层干涉影响,基于原始地震资料薄层描述难度大,而反射系数反演核心算法在提高砂体空间分辨率和消除薄层干涉方面虽有明显优势,但反演结果受噪声扰动明显。针对该问题,创新提出了多正则化参数不同反演结果加权叠加反演策略,有效压制了反演噪声,同时使薄层发育位置较弱的有效信号也得到了保持或增强。将该方法运用于车排子地区白垩系薄储层预测,结果显示白垩系底部扇三角洲砂体主要分布在西部近岸区域,且扇体内部厚度不一,而远源多为规模小、厚度薄的点状滩坝砂体。该方法有利于提高岩性圈闭及储层预测的可靠程度,指导井位部署,加快勘探开发进程。
Influenced by the resolution and thin layer interference, due to the difficulty of describing the thin layer based on the original seismic data, although the core algorithm of the reflection coefficient inversion has obvious advantages in improving the spatial resolution of the sand bodies and eliminating the thin layer interference, the inverted results are obviously disturbed by the noise. In the light of the problems stated above, the weighted stack inversion strategy with different inverted results of the multiple regularization parameters was proposed, thus the inversion noise was suppressed effectively, and moreover the weak effective signal of the thin-layer developed location was also maintained and enhanced. The method was applied in the Cretaceous thin reservoir description in Chepaizi area, the results show that the fan-delta sandbodies at the bottom of Cretaceous system are mainly distributed in the western coastal area, and the thickness is different inside the fan, while the most small-size and thin-thickness beach-bar sandbodies are distributed in the distant sources. The method is beneficial to enhance the reliabilities of the lithological trap and reservoir prediction, guide the well location arrangement and furthermore speed up the exploration and development processes.
