摘要
Diagenesis and features of the 3rd member of Feixianguan Formation in the Jiannan Gas Field were studied taking well Jian43 as an example. Dolomitization, karstification and tectonic disruption were contributive to reservoir. There were 4 kinds of diagenesis environment including seabed (intertidal), atmospheric water, shallow bury and deep bury. Dolomite crystals, secondary granular consolidations, eroded fluorites, tensional fissures and pores without obvious deformation were the main identifications for buried erosions.
