摘要

沙溪庙组是目前四川盆地陆相致密油气勘探开发重点层位,主力含气层系为沙二一段(J₂s¹₂)河道砂体,然而河道砂体与古地貌的耦合关系研究较为缺乏,制约了下一步致密气的精细勘探开发。针对这一问题,在建立川中地区等时格架的基础上,基于沉积补偿原理,充分考虑地层差异压实作用,采用印模法,半定量化恢复了J₂s¹₂段古地貌格局;综合岩心、测井和地震资料对J₂s¹₂段沉积体系进行了分析,在此基础上分析了各地貌单元和沉积微相之间的耦合关系。采用地震多属性融合方法进行了砂体厚度预测,提出了古地貌控制河道砂体分布及砂体优势运输通道,即“河谷输砂、河间丘分砂、缓坡阻砂”的结论。研究结果表明:川中地区J₂s¹₂段为谷丘相间的古地貌格局,南西高北东低,整体坡度较缓,主要发育主河谷、支河谷、河间丘和缓坡4类地貌单元;研究区J₂s¹₂段发育陆相河流沉积体系,河道砂体平面呈条带分布;J₂s¹₂段古地貌单元控制了沉积微相分布,河道沉积集中发育在河谷,河漫沉积多发育在缓坡。该研究成果对下一步致密气勘探工作具有一定的指导意义。

Abstract

The Shaximiao Formation is currently a key target for exploration and development of continental tight oil and gas in the Sichuan Basin,and the main gas-bearing series is the channel sand bodies of J₂s¹₂.However,the research on the coupling relationship between the channel sand bodies and palaeogeomorphology is scarce,which restricts further fine exploration and development of tight gas.To address this issue,based on the establishment of an isochronous framework in the central Sichuan Area and employing the principle of sedimentary compensation,the paleogeomorphology of the J₂s¹₂ was semi-quantitatively restored using the impression method while fully considering the differential compaction of strata.An integrated analysis of core,well logging,and seismic data was conducted on the J₂s¹₂ section of the sedimentary system,which then serves as the basis for analyzing the coupling relationships between various ancient landform units and sedimentary microfacies.The seismic multi-attribute integration method was utilized to predict the thickness of the sand bodies,proposing that palaeogeomorphology controls the distribution of channel sand bodies and the preferential pathways for sediment transport,namely "the valley transporting sand,interfluvial hill separating sand,and gentle slope stopping the sand".Research results indicate that J₂s¹₂ in the central Sichuan Area features ancient landform pattern of alternating valleys and hills,with higher elevations in the westsouth and lower elevations in the eastnorth,and an overall gentle slope.The area primarily consists of major river valleys,tributary valleys, interfluves,and gentle slopes.The main morphological units developed include primary valleys,tributary valleys,interfluvial hills,and gentle slopes.The J₂s¹₂ section in the study area features a continental river sedimentary system,with channel sand bodies distributed in a banded pattern.The ancient landform units of the J₂s¹₂ section control the distribution of sedimentary microfacies,with channel deposits concentrated in the valleys and floodplain deposits more frequently occurring on the gentle slopes. This research provides valuable insights for the subsequent exploration of tight gas.

Key words： palaeogeomorphology; channel sand body; impression method; sedimentary system; sand control mechanism; Shaximiao Formation; Sichuan Basin
