Title: Discussion on Sedimentary Relationship between Weixinan Sag and Haizhong Sag during Paleogene Period in Beibuwan Basin
Abstract: Weixinan Sag and Haizhong Sag is adjacent,but oil-gas exploration achievement and the understanding about petroleum geological conditions of both sags are different.By means of recovering original attitude of strata,influence of Weixinan low uplift on sedimentary environment of both sags during Paleogene was discussed and sedimentary accommodation space archetype was recovered during Palaeocene and Eocene.It’s believed that two sags were part connected during Palaeocene and fully connected during Eocene and Oligocene,and as part of boundary of the two sags,No.3 fault controlled the distribution and cubage of sedimentary accommodation space.Because the activity intensity of No.3 fault was maximum during Eocene,the sedimentary accommodation space was also maximum in Eocene.As these two sags were fully connected,an analogy can be drawn between hydrocarbon generation ability of Eocene strata in Weixinan Sag and Haizhong Sag.
