Abstract

There are clear hydrocarbon accumulation features for Xiaermen Oilfield in BiyangDep ression of Nanxiang Basin, which changed upward from pure reservoirs inMember He₃ and He₂ to reservoirs with gas cap in the upper part of Member He₂, and up to pure gas reservoirs in Member He₂ and Liaozhuang. Oil-source correlation shows that hydrocarbon in the upper part migrated and accumulated upward through long distance vertical migration from the lower mature gas-oil. Alongwith fast drawdown of boundary fracture during deposition of sand group Ⅵ in Member He₃, Xiaermen anticline structure came into being antithetic drag anticline structure together with deposition, but lifting am-plitude is not clear. This area was subjected to strong comp ression caused by early Himalayasmovement ( at the deposition last term of LiaozhuangMember), this caused Xiaermen ancline structure into fracture develop ing many trap types connected with faults. Correspondingly, this oilfield is characterized ofmulti-term reservoir-forming and modified reservoir-forming: (1) reservoir-forming took p lace in the paleo-reservoir-forming period at the position last term of Member He₁ ; (2) reservoir-forming took p lace in the period of destruction of paleo-reservoir and began the filling of mature oil-gas at the deposition last term of MemberL iaozhuang; (3) reservoir-forming took p lace at the end of struc- ture-rifting period in the late deposition, enough oil-gas filling before the Quaternary deposition. Hydrocarbon reservoir formingmodes are that hydrocarbon laterallymigrates through channels in single sand body and slowly fill and accumulate in the early term, and during mid and last term hydrocarbon fast migrate, fill and accumulate into reservoir because of sharp increase in potential energy caused by differential lifting motion, and vertical fracture modification at the end of Liangzhuang deposition period.
