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。
The Jiyang Depression, one of the important exploration areas in Shengli Oilfield, has relatively abundant oil and gas reserves. Based on the interpretation of high-precision seismic data, the characteristics of oil-bearing fault blocks in Jiyang Depression are analyzed. The research shows that the fault blocks in the depression have many faults, reverse fault blocks and small fault blocks. Many secondary faults are developed in the natural fault blocks. The fault blocks formed by multiple fault blocks are characterized by “grab” anticlines, reverse traction, dome anticlines and nose structures. In the section, the fault blocks are stepped, stepped, and “Y” Fault combination style based. The fault blocks are connected by transformational structures to form a structural deformation domain in which the dynamic deformation is coordinated with each other.
