上升盘

并且控制了沉积岩相的发育、分布，表现为在该断裂北侧下降盘形成伸展裂陷盆地，上升盘一侧发育浅海碳酸盐台地或孤立碳酸盐台地，断裂带构成二者的构造-古地理边界。

On its downthrow , extension-depression basin develops , and on the upthrow , neritic carbonate platform or isolated carbonate platform develops , it is the structure & paleo-geography boundary of the two kinds .

1号断裂上升盘缺乏良好的盖层；

Fault rising block is short of good seal .

正断层在地震剖面中有多种特征，但人们通常认为：1正断层下降盘地层厚度一定要大于或等于上升盘地层厚度；

The normal fault has multiple features on seismic section , the people often considered : ① Thickness of strata in downthrow side must greater than or equal to that in uplifted side ;

沙四上亚段沉积时期，胜坨地区存在两个不同的物源体系，即坨94断层上升盘物源和胜北断层上升盘物源。

The results indicate that there were two different provenance systems during the deposition of the upper Es4 : one on the upthrow of the Tuo94fault and the other on the upthrow of the Shengbei fault .

对于构造油藏，位于断层上升盘的油井在投产初期要比位于下降盘上的油井产油量高、含水低、开发效果好。

As for structural hydrocarbon reservoir , the oil well on up-thrown block has higher daily oil production , lower water cut and better development performance compared with the oil well on down-thrown block in block faulted oilfield .
