西非 Ｒio Muni 盆地复杂盐拱构造油藏特征

为精细解剖西非油气富集的 Ｒio Muni 盆地复杂盐拱构造带上的油藏特征，为其他相似地区油藏评价提供一定参考，以位于复杂盐拱构造带上的 H 油藏为例，利用地震、测井、录井、钻井和 MDT 测试等资料分析 H 油藏的构造、沉积、储层和油层分布特征及成藏主控因素等。研究得出，H 油藏属于典型的构造岩性复合油藏，为构造背景下的岩性边水油藏，具有多套油水系统，构造高部位发育盐刺穿，储层既有浊积砂岩储层又有滑脱灰岩储层，主要分布于构造的翼部低部位，滑脱断层和盐拱是油气成藏的主控因素。

Ｒeservoir characteristics of complex salt- arch structure in Ｒio Muni Basin，West Africa

In order to fine analyse the reservoir characteristics on complex salt- arch tectonic belt in Ｒio 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．
