勘探资料证实，西湖凹陷内生成的油气由生烃深凹向西部和南部的古斜坡带运移。
The exploration data approve that the hydrocarbon in the Xihu Depression migrated from the deep depression of hydrocarbon-generating to the west and south parts of the ancient slope.
油气主要以T1，T2界面和储层的侧向运移为主导，叠置在古隆起、古斜坡之上的各类圈闭是最有利的圈闭，成藏效率高。
Oil and gas in the basin migrated laterally along T1, T2 interfaces and reservoirs. Verious kinds of traps superposed on paleo-uplifts and paleoslopes are more favourable to form oil and gas pools.
沿盆地长轴方向，在坡降缓、斜坡长的古地形等条件下，源远流长地巨大的定向曲流河携带大量的泥沙进入湖盆，在河湖作用过渡带形成曲流河三角洲沉积体。
The immense oriented meandering river, along the long axis of the depression and with the gentle declivity and long slope, carried a large amount of mud and sand into the lake basin.
古隆起斜坡带控制隐蔽油气藏的分布。
Ancient heave slope band controls distributing of subtle trap.
孤北断层持续不均衡发育形成孤北斜坡带沟梁相间、陡缓变化的古地貌，古地貌控制了隐蔽圈闭的平面分布。
Continuous disproportionate growth of Gubei fault formed the palaeogeomorphology of Gubei slope belt with groove alternating with roof and with abrupt and gentle change.
因此古地貌高地、古地貌斜坡与洼地中的局部地貌隆起将是层间岩溶作用发育的最有利区带。
Therefore the partial landform uplift among the ancient landform highland, the ancient landform slope and the marsh land will be most advantageous area belt of the growth of interlayer karst process.
伊盟隆起地抽侧斜坡及中央古隆起四周斜坡地带，是寻找古生界天然气的有利场所；
The south slope of the northern Yimeng Uplift and the slope region around the central uplift are favorable for seeking Paleozoic natural gas.
