1) Eoorogenic phase
潜伏造山幕
2) 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。
3) buried structure
潜伏构造
1.
The Fangdoushan and Qiyueshan buried structures are both favorable for preservation,with the former better than the latter.
石柱复向斜主体因盖层完整、特别是下三叠统嘉陵江组膏盐岩盖层连片分布且断裂构造不发育而保存条件最好;方斗山、齐岳山潜伏构造保存条件较好,但位于西侧的方斗山潜伏构造要好于齐岳山潜伏构造;复背斜主体因区域大断层的开启及区域盖层的剥蚀而保存条件较差;利川复向斜南部盖层较完整,保存条件较好,而北部较差。
4) holoorogenic phase
全造山幕
5) orophase
造山幕
6) buried structural belt
潜伏构造带
