| 摘 要： | 渤南洼陷是济阳坳陷沾化凹陷中的一个三级负向单元,具有丰富的油气资源。文章从渤南洼陷的地层温度场和地层压力场出发,总结了该洼陷的地温场和地压场的平面和剖面特征,以及地温-地压场的耦合特征,并分析了地温-地压场特征与油气分布的关系。综合研究认为,渤南洼陷具有超压型复式温压系统特征;油气分布主要集中在相对低能的温压分区范围内。

| Abstract: | nan subsag, a third-order negative unit in Zhanhua sag, Jiyang Depression, possesses abundant hydrocarbon resource. Based on geothermal-formation pressure field of the subsag, in this paper, the plane and section characteristics of the geothermal-formation pressure field, and the coupling characteristic of geothermal-formation pressure system ( T-P system) in Bonan sub sag are summed up, and the relation between these characteristics and hydrocarbon distribution is analyzed. The comprehensive research shows that the Bonan subsag has the characteristic of overpressure multiple T-P system. Hydrocarbon is mainly distributed in T-P subarea with relative low energy. |

| Keywords: | P system abnormal pressure hydrocarbon distribution Bonan subsag |
