中文摘要：

蠡县斜坡的鼻状构造带控制了油气的运聚与成藏，此构造带主要由基底古凸起背景下的继承性发育和后期的差异压实作用形成，具有持续发育、幕式演化的特征，可分为沙四段、孔店组-基底、沙三段-沙-下亚段、沙-上亚段和东营组4个阶段。这种特征对油气成藏具有3个控制作用：鼻状构造的发育期次控制砂体在两翼形成超覆尖灭型砂体，后期鼻状构造脊部发育河道透镜状砂体；长期的构造高部位控制了油气的运聚，可形成断鼻油藏、上倾尖灭油藏、砂岩透镜体油藏和构造-岩性油藏；构造-岩性油藏是蠡县斜坡最普遍的油藏类型。

英文摘要：

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.
