【摘要】：油田勘探开发实践证实斜坡区同向和反向断层圈闭均是油气勘探的潜力区。以束鹿斜坡西曹固构造带为研究靶区,从断层变形机制出发,结合断层分段生长理论,系统探讨斜坡区同向和反向断层形成机制及控圈作用差异性。研究结果表明:由于断层差异活动和分段生长作用,反向断圈形成于下盘分段生长点之间,而同向断层圈闭形成于上盘分段生长点上;基于断圈面积和断距的关系分析,认为反向断层控圈面积和幅度明显大于同向断层。
[Abstract]:The exploration and development practice in oil field has proved that the codirectional and reverse fault traps in the slope area are potential areas for oil and gas exploration. Based on the fault deformation mechanism, the Caogu structural belt in the west of Shulu Slope is taken as the research target. Based on the theory of fault segmental growth, the formation mechanism of codirectional and reverse faults and the difference of cycle controlling effect in slope region are systematically discussed. The results show that: due to fault differential activity and segmental growth. The reverse fault circle is formed between the sub-growth points of the lower disc, while the codirectional fault trap is formed at the growing point of the upper section. Based on the analysis of the relationship between the fault area and the fault distance, it is considered that the area and amplitude of the reverse fault control circle are obviously larger than that of the same direction fault.

【正文快照】： 中国陆相盆地断裂构造十分发育,断裂对盆地的成盆、成烃和成藏的各个过程都有重要的影响,断裂在油气成藏中的作用也日益受到地质学家及石油勘探家们的重视,对其研究的力度和深度都在不断增加[1-2]。特别是裂陷盆地斜坡构造带,其是油气运移的最终指向区,斜坡带断裂相对较发育,
