Control Effects of the Sequence Stratigraphy in the Terrestrial Lacustrine Basin Clastic Rock to the Diagenesis of Reservoirs

Nowadays,the main exploration targets of the continental oil fields in China are aiming at the subtle reservoirs,such as lithologic and stratigraphic reservoirs.The quantitative and predictive diagenesis researches are important to subtle reservoirs exploration.To discuss the control of sequence boundary and systems tract on the diagenesis,diagenetic evolution sequence and its impact on reservoir properties demands combining researches of diagenesis and sequence stratigraphy,which provide new ideas for the regional evaluation and prediction of hydrocarbon reservoirs.But the literature studies about the diagenetic sequence stratigraphy of terrestrial lacustrine basin in china are limited.This paper reviewed a large amount of literatures,summarized the control of sequence boundary and systems tract in terrestrial lacustrine basin on reservoir diagenesis,diagenetic evolutionary pathways and diagenetic facies,and discussed the related researches of the branch discipline:diagenetic sequence stratigraphy,including the history and development of diagenetic sequence strtigraphic concepts,main research contents,application trend,future research direction and currently undissolved problems.Then the future development direction of diagenetic sequence stratigraphy of terrestrial lacustrine basin was summarized from the aspects of improvement of related theories and methods,analytical techniques and the inter-science crossing and penetration.
