The Putaohua Oilfield is a fault-prolific area and the faults have close relation with structural traps. The genetic models of the structural traps in the Putaohua Oilfield can be divided into two types： individual fault model and multi-fault interaction model. This is based on the description of displacement distribution of typical individual normal faults, the geometry of the footwall and hanging wall, and the analysis of the interaction between faults and the corresponding change in geometry when the faults grow. The individual fault model is that the displacement reaches a maximum at or near the center of fault and decreases toward the fault tips, so a half-graben is formed on the hanging wall of the fault and a half- anticline is formed on the footwall because of the isostatic process. The multi-fault interaction model is that during the growth of faults, they overlap and interact with each other, and accommodation zones are formed in the overlapping segments. The accommodation zones are favorable targets for hydrocarbon exploration, and the trap characteristics are dependent The multi-fault interaction model can be subdivided on the extent of overlap and occurrence of faults. into three types： synthetic accommodation zone, convergent accommodation zone and divergent accommodation zone. Hydrocarbon migration and accumulation models of each type have been developed. The hydrocarbon migration and accumulation models of the traps with different genetic models have their own characteristics in the different stages of fault growth.

应用调节构造理论,以断层生长分析为基础,在东濮凹陷识别出3大类共13个调节构造。同向型调节构造主要分布于分段活动的兰聊断层各断层段连接处及雁列型排列的长垣断层系内各断层叠覆段,其几何形态分别表现为断鼻及与断层斜交的斜坡,起到分隔凹陷东部与西部洼陷带的作用;对向型调节构造主要由倾向相对的兰聊断层各断层段与长垣断层各断层(段)叠覆形成,表现为较为完整的背斜形态,是凹陷中央隆起带的组成部分;背向型调节构造发育于凹陷中央隆起带上倾向相反的断层叠覆带,表现为条形凸起,与对向平行型调节构造叠加在一起。该区调节构造主要与东西边界断层(系)在分段期的相互作用有关。调节构造作为凹陷中相对高地势带并分隔半地堑,从多个方向邻近烃源,是有利的油气勘探目标。

通过铸体薄片和分析化验资料,分析了张店油田核桃园组二段储层中碳酸盐胶结物的产状及其含量随深度变化的规律。储层中碳酸盐含量总体上随深度增加而不断加大,但在不同成岩阶段具有不同特点。在有机质成熟期尤其是半成熟-低成熟阶段(晚成岩早期),碳酸盐含量下降明显,是次生孔隙主要发育期。在晚成岩B亚期(晚成岩晚期)以后即有机质生烃高峰期以后,储层中尤其是高孔隙储层中碳酸盐胶结物含量增加明显。碳酸盐在储层中的不断富集与泥岩压实作用和有机质成熟期的酸性孔隙水溶解作用有关。不同微相中碳酸盐富集部位不同。对于三角洲前缘分支水道微相,它主要富集于砂体底部;而对于河口砂坝,则主要富集于砂体顶部。碳酸盐在储层中的富集是造成储层孔隙度下降的主要因素之一,它对2 450 m深度以下储层影响尤为严重。
