摘要

摘要: 采用地震地质综合预测技术，对川东北地区开江-梁平海槽东侧上二叠统长兴组生物礁沉积相特征、主控因素和礁相油气藏进行了研究。通过单井沉积相研究，查明该区生物礁纵向发育有两期，长兴组沉积期的古地貌对生物礁发育及迁移具有控制作用，坡度越大生物礁越厚。早期古地貌控制了生物礁的发育，在北部陡坡沉积区发育早期生物礁且成条带状，在南部缓坡沉积区发育晚期生物礁且成块状；晚期古地貌控制了生物礁向台地方向迁移，发育第二排生物礁。针对不同区域沉积环境的差异，采用针对性的预测技术。在中部沉积陡缓转折带，优选台缘带内长兴组顶部振幅属性预测生物礁厚度；在南部缓坡沉积区，采用基于地震沉积学的分频解释技术预测生物礁。预测成果经实钻证实，多口井获得高产气流。

Abstract: The sedimentary characteristics, main controlling factors and reef reservoir facies of the Upper Permian Changxing Formation reef on the eastern side of the Kaijiang-Liangping trough in the northeastern Sichuan Basin were studied using comprehensive seismic prediction technology.Through the study of single well sedimentary facies, it is found that there are two stages of longitudinal development of the reefs in this area. The paleogeomorphology of the Changxing Formation has a controlling effect on the development and migration of the reefs:the larger the slope, the thicker the reefs.Early paleo-geomorphology controlled the development of reefs. In the northern steep slope zone, early reef strips developed, while in the southern gentle slope zone, late reef blocks developed. Late paleotopography controlled the migration of reefs to the platform, resulting in the second row of reefs.Targeted prediction techniques were used to account for differences in sedimentary environments in different regions. In the central transitional belt, the amplitude property on the top of Changxing Formation on the platform margin was optimized to predict reef thickness. In the southern gentle slope sedimentary zone, the bioreef is predicted by the seismic-based interpretation technique. The predicted results have been confirmed by actual drilling, and many wells have obtained high-yield gas flow.
