摘      要：In order to reveal the relationship between the penecontemporaneous karstification and sedimentary microtopography in sequence stratigraphy,the sequence stratigraphic framework of Lianglitage formation in Upper Ordovician is studied according to the well drilling,logging,geophysical data,detailed observations of core and the *** Lianglitage formation belongs to the sequence Ⅳ of *** second member of Lianglitage formation is prograde sedimentation in highstand systems tract,and is favorable for developing reef *** development scale and thickness of reef flat are controlled by the variation of secondary sea *** types and characteristics of karst in the highstand systems tract show that the late highstand systems tract is dissolved and cemented by the meteoric fresh water and mixed *** karstification is developed at the top of parasequence and high place of *** diagenetic lens is *** developing regulations and controlling factors of penecontemporaneous karstification can provide new clues to the prediction and exploration of favorable reservoir in this area.
