二连盆地潜山成藏条件及油藏类型

潜山油藏具有埋藏浅、产量高、效益佳的特点。文章深入分析了二连盆地潜山成藏的地质条件，总结了以石炭系碳酸盐岩风化壳油藏为代表的5 种油藏类型，指出潜山的油气运移系统以断裂为主，其储集物性主要受断裂和风化淋滤作用的控制。研究结果对二连盆地及具相似地质条件的其它地区潜山油藏的勘探具有一定的指导作用。

Reservoir accumulation conditions and patterns of buried hill in Erlian Basin

There are some features of shallow bury, high production, fine benefit for buried-hill reservoirs. The article analyses the geology of buried-hill reservoirs in Erlian Basin and summarizes five reservoir types. The weathering crust reservoir of carbonate rocks in Carboniferous is the representative. The article indicates that the main system of hydrocarbon migration of buried-hill is fault, its reservoir physical properties are mainly controlled by fault and weathering eluviations. This study provides the guidance to exploration of Erlian Basin and other buried hill reservoirs of similar geologic condition.
