走滑-伸展断裂叠合特征及其控藏作用
|
摘要
渤海湾盆地(海域)新生代受伸展和走滑双重作用控制,形成了复杂的走滑-伸展叠合构造区。基于全区三维地震和钻井等资料,对渤海湾盆地(海域)南北部构造特征、动力学机制的差异性及其对油气成藏的控制作用进行了研究,得出了以下结论:盆地南部和北部走滑-伸展叠合作用方式存在明显差异,南部的黄河口和莱州湾凹陷为始新世—渐新世的弱伸展和新近纪的强走滑作用近平行叠加;北部的辽东湾坳陷为始新世—渐新世的强伸展和新近纪的弱走滑作用近垂直叠加。叠合作用方式的不同控制了南北部油气差异成藏,南部油气主要分布于凹陷区的走滑带,成藏层系以新近系为主;北部辽东湾坳陷油气主要分布于陡坡带和凸起区,成藏层系以古近系为主。该研究对渤海湾盆地不同构造区油气差异成藏理论研究具有重要意义。
The Cenozoic strata in Bohai Bay Basin( seas) is dependent on the dual actions of strike-slip and extension,which leads to a complex strike-slip-extension superimposed structural zone. The structure properties and dynamic mechanism differences of the southern and northern Bohai Bay Basin( seas) and their effects on hydrocarbon accumulation were investigated on the basis of the whole 3 D seismic and drilling data. Result indicates that there are significant differences of strike-slip-extension superposition patterns in the southern and northern parts. The southern Yellow River Mouth and Laizhou Bay Sags are considered as nearly parallel superposition between the EoceneOligocene weak extension and the Neogene strong strike-slip effects. The Liaodong Bay depression in the north is a vertical superposition between the Eocene-Oligocene strong extension and the Neogene weak strike-slip effects.Different superposition patterns result in the difference in hydrocarbon accumulation between the southern and northern parts. The hydrocarbon in the southern part mainly distributes in the slip zone of the depression,and the hydrocarbon accumulation strata series is dominated by Neogene strata. The hydrocarbon in the northern part mainly distributes in the steep slope and bulge zones,and the hydrocarbon accumulation strata series is dominated by the Paleogene strata. This research could provide certain significance for the study of diverse hydrocarbon accumulation theories in the different structural areas of the Bohai Bay Basin.
