Oil and gas migration and their reservoir formation in Lixian Slope are controlled by the nose-like struc-tural belts mainly resulted from the inherited development and later-period differential compaction against the back- ground of the uplift of the basement. The belts are characterized by eontinous development and episodic evolution, which are divided into 4 stages, namely Basement-Es4, Es3-ESlX, Es1sand Ed. This kind of characteristic has 3 kinds of controlling actions to the hydrocarbon accumulation： the development periods and times control the formation of overlying pinchout-type sandbodies along the two wings, the later nose-like structural crest makes channel len-shaped sandbodies developed; tong-existed structural peak dominates the petroleum migration and results in the formation of the following oil reservoirs ： faulted nose, updip pinehout, sandstone lens and structural lithologic one ; the latter is the most popular type of the oil reservoir on Lixian Slope.
