1) buried-hill stratigraphy
古潜山内幕地层
2) interior reservoir in buried hills
古潜山内幕油藏
3) pa-leo-buried hill formation
古潜山地层
4) inner buried hill
潜山内幕
1.
Inner buried hill laminar formation or lithology association together with minor faults form inner buried hill traps.
大民屯凹陷隐蔽型潜山是低平或负向形态的元古宇或太古宇基底潜山,中生界、古近系房身泡组或沙四段的非渗透层对不整合面形成封闭,在多期构造运动改造、风化剥蚀作用下,具有多种较好的储集岩性和多期发育的裂缝型储集层,潜山内幕层状地层或层状岩性组合与微幅度断层一起构成潜山内幕圈闭,来自各生油洼陷的油气首先沿连通油源的深大断裂垂向运移,之后沿不整合面长距离侧向运移至隐蔽型潜山圈闭,形成潜山油藏。
2.
The exploration work for buried hill reservoir has changed from much distinct hill,such as top buried hill,middle part buried hill to much deeper,blinder,complex buried hill,such as,lowly buried hill,inner buried hill.
辽河坳陷潜山油气藏勘探近年来不断取得重大突破,实现了由寻找成藏条件相对明显的高、中潜山向寻找埋藏更深、更隐蔽、更复杂的低潜山和潜山内幕油气藏的勘探转变。
3.
Exploration targets have shifted from the Shallow-medium buried hill reservoirs with clearer reservoir forming conditions to the low and inner buried hill reservoirs with deeper,hidden and more complex features.
近年来,辽河坳陷潜山油气藏勘探不断取得重大突破,实现了由寻找成藏条件相对明显的高、中潜山向寻找埋藏更深、更隐蔽、更复杂的低潜山和潜山内幕油气藏的勘探转变。
5) internal episodic synclinal buried hill
内幕向斜型潜山
1.
It was found in the research of Yuanguyu Buried Hill in Damintun Depression of Liaohe Oilfield that they belonged to internal episodic synclinal buried hills.
前人对潜山油气藏做了大量研究,但是对向斜型潜山却很少有报道,对成藏特征分析未见文献报道,笔者在对辽河大民屯凹陷元古宇潜山研究时发现它们都属于内幕向斜型潜山,系统阐述了向斜型潜山的确定依据,并分析了成藏条件,指出了向斜型潜山除具有一般潜山油气藏特征外,还具有独特的成藏特征,即具有多层系含油和翼部成藏的特点,内幕向斜型潜山的提出,丰富了我国潜山成藏理论,扩大了潜山勘探领域。
6) reservoirs in buried-hills
