摘要
西湖凹陷位于东海盆地东部,凹陷内正反转构造发育.反转构造与油气成藏密切相关,目前西湖凹陷已发现油气储量的90%与反转构造有关.西湖凹陷油气资源丰富,储盖组合条件较好,大多数反转构造形成时间与烃源岩生排烃高峰期相匹配.中央反转构造带、西斜坡反转构造带与东斜坡反转构造带是有利油气聚集带.
Xihu sag is located in the eastern East China Sea basin, where normal inversion structures have developed. The inversion structures are closely related to hydrocarbon accumulation, and about 90% of the reserves discovered are associated with these structures in the sag. Xihu sag has abundant resources and good reservoir_seal combination, and most inversion structures are matchable in their formation periods with the peak stages of hydrocarbon generation and expulsion. The Central, the West Slope and the East Slope inverted structure zones are all favorable for hydrocarbon accumulation.
