In order to fine analyse the reservoir characteristics on complex salt- arch tectonic belt in ��io Muni Basin of west Africa��and provide certain reference for other similar reservoir evaluation��we take the H reservoir as an example�� The structure��sediment��reservoir��oil distribution and main controlling factors of reservoir are ana- lyzed according to the seismic data��wireline logging��mud logging��drilling and MDT�� The conclusion is that the H reservoir is a litho- structural reservoir��lithologic edge water oil pool with some oil- water contact in structural set- ting�� There is salt diapir in the crest�� The reservoir has both turbidite sandstone and gravitational decollement lime- stone in lower part of this trap�� Decollement fault and salt diapir are the main factors of oil accumulation��
