济阳坳陷断块油藏构造特征
|
摘要
作为胜利油田重要探区之一的济阳坳陷油气储量相对丰富。在高精度地震资料解释的基础上,对济阳坳陷含油断块特征进行了分析。研究表明,坳陷内断块具有断层多、反向断块多、断块小的特征,自然断块内部发育众多的次级断层。多个断块所构成的断块区表现为"堑式"背斜、逆牵引、穹窿背斜及鼻状等构造形态;剖面上以地垒、阶梯状及"Y"字型断层组合样式为主。断块之间通过变换构造相连接,形成一个动力学变形相互协调的构造变形域。
As one of the most important exploratory areas,the oil and natural gas reserves of Jiyang Depression are relatively abundant.With the interpretation of high precision seismic data,the character of Jiyang Depression oil-bearing blocks has been analyzed.The research shows that the fault-blocks in the depression are featured by large amount of faults and lots of counter regional faults and smaller fault-blocks,which contains many secondary faults.The block zone composed of many fault-blocks shows a structure form of graben-anticline or reverse drag anticline or dome and nose structure.And the main profile composite patterns are horst,stepladderhorst and "Y" font.Fault-blocks are connected by transition structure,which forms a dynamic deformation coordinated tectonic deformation of the domain.
