摘要：

中、下侏罗统是柴达木盆地东部主力生烃层系，针对前人“早—中侏罗世广盆沉积、现今凹陷均残留分布”的普遍认识与实际钻探不相符的矛盾，在充分利用野外地质调查、钻井、地震、电法等成果资料基础上，系统梳理了侏罗系露头层段归属与横向差异，研究了早—中侏罗世原始沉积与残留分布规律，认为研究区早—中侏罗世发育鱼卡、红山、德令哈、霍布逊等4个分隔性湖盆，并非广盆沉积，马海古隆起、欧龙布鲁克低凸起等造成原始沉积湖盆分割性较强；中、下侏罗统平面上局限分布于尕西、鱼卡、红山、小柴旦、霍布逊和德令哈等6个凹陷，并且在凹陷带、山前冲断带均有分布，并非与现今凹陷一一对应，欧南、大柴旦等凹陷均不发育中、下侏罗统。其残留分布主要受控于早—中侏罗世原始沉积和燕山运动晚期隆升改造两大因素，平面上严格受南祁连、埃南等NW向控山、控凹断裂和马仙等NE向、近EW向调节断裂的双重控制，从而造成现今凹陷之间、控凹断裂上下盘之间中、下侏罗统残留厚度的差异。

Abstract:

Middle and Lower Jurassic are main hydrocarbon generation layers in the eastern Qaidam Basin.It is used to being widely accepted that broad basin was developed during the Early-Middle Jurassic,and residual strata can be found in each sag at present.However,these ideas don't meet well with drilling practice.In face of such situation,the author made full use of field survey,drilling data,seismic data,and electric survey results,analyzed time correlation and lateral variation of outcrops,and studied original sedimentary system and distribution rules of residual strata.It is pointed out that during the Early-Middle Jurassic there developed four separated lake basins instead of broad basin namely Yuka,Hongshan,Delingha and Huobuxun,and Mahai paleohigh and Oulongbuluke low uplift separated the original lake basin into several small ones.Residual strata of Middle-Lower Jurassic were limited in sags such as Gaxi,Yuka,Hongshan,Xiaochaidan,Huobuxun,and Delingha,etc.Residual strata were developed in both sag area and piedmont thrust belt,but not correspond with present sags,such strata were not found in Ounan Sag and Dachaidan Sag,for instance.Distribution of residual strata was mainly controlled by the development of original sedimentation and reconstruction of uplift during Late Yanshan Movement.Laterally,residual strata distribution was strictly confined by NW striking mountain-controlling faults and sag-controlling faults such as South Qilian fault and Ainan fault,and NE striking or EW striking accommodation faults such as Maxian fault.Coupled influence of big faults and accommodation faults resulted in difference in development of residual strata between two walls of a fault and among sags.

Key words: Controlling factors, Distribution of remnant thickness, Middle-Lower Jurassic, Original sediments, Qaidam Basin
