摘要/Abstract

摘要：

四川盆地川西坳陷上三叠统须家河组沉积时期经历了海相—海-陆过渡相—陆相沉积环境的转变，龙门山隆升过程中坳陷周缘不同物源供砂的差异性致使盆内砂体展布规律复杂、储集体非均质性强。以川西坳陷须家河组二段和四段为研究重点，结合钻、测井以及地震资料，阐明沉积地层及砂体展布特征，揭示须家河组沉积时期沉积充填过程及其对龙门山隆升的响应。须二段沉积时期，龙门山北段局部隆升，弱挤压与强物源供给背景，以米仓山-大巴山供砂为主；海-陆过渡相三角洲前缘叠置河道具有相对的一致性与继承性，北部主河道向东迁移。须三段沉积时期，龙门山北、中段整体表现为水下隆起，强挤压与弱物源供给背景，南部康滇古陆及米仓山-大巴山为主要物源；海-陆过渡相三角洲砂体主要发育于坳陷北部和南部斜坡部位，滩坝砂体呈点状局部发育坳陷中央。须四段沉积时期，龙门山北、中、南段全面隆升，弱挤压与强物源供给背景，会同北部米仓山-大巴山双侧供砂且整体连片；湖相三角洲砂体范围稳定，总体呈NW-SE与NE-SW双向展布。龙门山幕式挤压过程中隆升强度和时序的差异共同控制了各沉积时期坳陷内砂体的沉积充填过程。

Abstract:

The Upper Triassic Xujiahe Formation in Western Sichuan Depression, Sichuan Basin, was deposited against a marine to terrestrial backdrop.With nearby Longmenshan uplifting during the period, the formation received various provenance inputs that led to a complex sandstone distribution and high reservoir heterogeneity.To reveal the distribution of sand bodies as well as the depositional history and response of the formation to the uplifting, we took the second to fourth members as study objects and analyzed their drilling, logging and seismic data.The results suggest that the uplifting of northern Longmenshan with weak extrusion and intense sediment flux led to a major supply of sands from Micangshan-Dabashan during the deposition of the second member.The stacked channels at the transitional delta front show a relative consistency and inheritance, with the main drainage line migrating eastward.The underwater uplifting of northern and middle parts of the mountain with intensive extrusion and weak sediment flux resulted in a supply of sediments from ancient Kangdian land and Micangshan-Dabashan during the deposition of the third member, with deltaic sand bodies mainly distributing in the north and south of the basin and sand bars in the center of the basin.During the deposition of the fourth member, the northern, central and southern parts of the mountain had all been uplifted.And with a weak extrusion and intensive sediment flux, the uplifting introduced a supply of sediments from both Micangshan-Dabashan and Longmenshan, resulting in a wide distribution of lacustrine delta sandstones of NW-SE and NE-SW orientations.It concludes that the uplifting intensity disparity and rising sequence of the different parts of Longmenshan during the episodic extrusion process are probably the joint controlling factors on the depositional processes and accumulation of sediments in the Western Sichuan Depression.

Key words: heterogeneity, sand body distribution, depositional filling, Longmenshan, Xujiahe Formation, Western Sichuan Depression, Sichuan Basin
