【摘要】 以构造坡折带理论为指导,通过地震资料、测井资料的综合应用,对渤海湾盆地饶阳凹陷南马庄构造坡折带类型,以及与砂砾岩体分布的关系进行了研究,并探讨了构造坡折带与岩性油气藏形成的关系。研究表明,根据断裂发育特征及组合样式,南马庄构造坡折带可分为梳状构造坡折带、帚状构造坡折带和阶梯状构造坡折带3类。不同的构造坡折带具有不同的发育特征,并且对砂砾岩体的控制作用也有所不同。总体来说,构造坡折带主干断裂及物源方向控制着砂体发育的位置,构造坡折带之下砂体明显加厚,砂体的展布方向受控于构造坡折带断裂的走向。构造坡折带容易形成岩性或断层—岩性等岩性油气藏圈闭,是进行岩性油气藏勘探的重要区带。更多还原

【Abstract】 Under the guidance of tectonic slope-break theory,the types of tectonic slope-break in Nanmazhuang area of Raoyang Depression of Bohai Bay Basin and relationship between distribution of sand bodies and types are researched by using seismic and well log data.The genetic mechanism of lithologic oil and gas reservoir at tectonic slope-break in this area is also discussed.The results indicate that the types of tectonic slope-break in Nanmazhuang can be divided into three types according to faults basic characteristics and combined style,they are "comb-like tectonic slope-break","broom-like tectonic slope-break" and "ladder-like tectonic slope-break".Different types have different control on distribution of sand bodies,but as a whole,main faults of tectonic slope-break and direction of sediment influx system determine forming location of sand bodies,and strike of main faults controls stretch direction of sand bodies.The tectonic slope-break zone is favorable and important for the formation of subtle oil and gas reservoir,such as lithologic reservoir.更多还原
