摘要/Abstract

摘要： 通过二维、三维地震剖面解释和运用平衡剖面技术观点，对焦石坝地区基底结构、中、古生界构造特征及其构造演化进行了研究。研究结果表明，该区存在着基底卷入和盖层滑脱2种构造类型。基底卷入型有背冲背斜、对冲向斜、叠瓦逆冲、正花状扭动和多字形扭动5种构造样式。盖层滑脱型有断展或断弯、断滑、叠瓦逆冲、叠瓦反冲、冲断楔5种构造样式和组合。燕山早、中期是该区的2个主要构造变形期，在燕山早期，中、古生界与基底及其内幕之间近水平向西拆离滑脱推覆，形成了侏罗山隔挡式背-向斜交替褶皱。方斗山断裂与大天池背斜之间的焦石坝地区为挤压宽缓复向斜背景；在燕山中期，受东邻隔槽带中、深层基底拆离向西强烈冲断作用，焦石坝地区形成了仰冲-逆冲-掩冲构造格局，经历基底叠瓦冲断-盖层滑脱-左行压扭3个变形幕，形成了焦石坝双层背冲背斜及翼部的断褶带。石门断褶带具有多层滑脱褶皱特征，乌江断褶带具有滑脱与左行压扭的性质。构造变形性质与类型、龙马溪组-五峰组滑脱程度、层滑作用产生的构造缝是该区形成大型页岩气田重要的构造影响因素。

Abstract: Through 2D and 3D seismic interpretation and application of balanced cross section technique,basement structure,and tectonic characteristics and its evolution of the Mesozoic-Paleozoic of Jiaoshiba area,the Sichuan Basin are analyzed in this study.The results show that there are two types of structures in the study area.The first type is basement-involved structure,which is characterized by five structural patterns and assemblages,including back thrust anticlines,ramp syncline,imbricate thrusting,positive flower wrench and "多"-shaped wrench.The other type is cap detachment structure,which is characterized by five structural patterns and assemblages,including fault-propagation or fault-bend,fault-slipping,imbricate thrusting,imbricate ramp and thrust wedge.Additionally,the Early and Middle Yanshanian period are two major tectonic deformation periods.During the Early Yanshanian period,the nearly horizontal westwards detachment and decollement-nappe structures occurred along the interface between the Mesozoic-Paleozoic and the basement and the interfaces within the basement,resulting in the anticline-syncline alternating Zhuluoshan fold.The Jiaoshiba area between Fangdoushan fault and Datianchi anticline is within a broad compressional synclinorium structural background.During the Middle Yanshanian period,the detachment of the middle-deep burial basement in the eastern trough-like fold belt caused intensive westward thrusting,and then led to the formation of the tectonic framework of obduction-thrust-overthrust in the Jiaoshiba area.The double-layer back-thrusting anticline and faulted fold belt in the flanks were formed in Jiaoshiba area after three deformation episodes,including basement-involved imbricate thrusting-cap rock decollement-left-lateral transpression.Furthermore,Shimen faulted fold belt is characterized by multi-layer detachment folding structure and Wujiang fault-fold belt is characterized by detachment and left-lateral transpression structure.The tectonic deformation properties and types,decollement degree of the Longmaxi and Wufeng Formations,and layer-slipping structural fractures are the major tectonic factors controlling the shale gas play.

Key words: double-layer back thrusting, multi-layer decollement, basement detachment, ejective folding, shale gas, Jiaoshiba anticline and its periphery, Sichuan Basin
