After have systematically studied sequence stratigraphy of chagan depression , a analysis method of high precision sequence stratigraphic framework in fault - depressed lacustrine basin . the core of the establishing framework is exploration - significant identify of sequence , division of 2 , 3 , 4 , 5 grades sequence and analysis of base - level based on lithologic log or well - logging , high - resolution seismic inversion constrained to well data . then using the results of 2d seismic data , and interpret sequence to enhance the precision of interpretation
2.
Guided by the theory of sequence stratigraphy and petroleum system using cores , lithologic log or well - logging , biostratigraphic and seismic data , adopting seismic inversion constrained to well data , digital analysis technology , basin modeling , test method and so on , and adopting an integrated study technology , aiming at lower exploration in chagan depression , this work put forward a new research thoughtfulness , technic flow and method system that is an integrated study by " looked upon sequence stratigraphy as a base , looked upon petroleum system as a integer , combing with each other closely " and tie in qualitative analysis and quantitative analysis and applied synthetically new theory , new technology and new method
