在分析东营凹陷构造格局基础上,研究了陈官庄—王家岗地区的区域断裂展布及第三纪应力场背景,探讨了陈王断裂带形成的动力学机制,认为该断裂带是在第三纪由区域右旋张剪应力背景下,使该区基底断层继承性活动与斜坡带的重力作用共同形成的雁行状断裂构造带。该断裂带控制了王家岗油气田的形成及构造特征,进行了含油气区块划分,认为该油气主要富集于“北部高断鼻带”和“中部地堑带”的沙二段,并指出了下一步油气勘探的三个领域。
Based on the analysis of tectonic structure of Dongying depression, the regional fault distribution and the background of Tertiary stress field in Chenguanzhuang-Wangjiagang area are studied, and the dynamic mechanism of the formation of Chenwang fault zone is discussed. It is considered that the fault zone was formed in Tertiary Under the background of dextral tensile shear stress in the region, the synoptic fault zone formed by the inherited activities of the basement faults and the gravity of the slope zone is formed. The fault zone controls the formation and structural features of the Wangjiagang oil and gas field. The division of oil and gas blocks is carried out. The oil and gas are mainly concentrated in the second section of Shaheer of “northern high cut nose zone” and “middle graben zone”, and pointed out The next three areas of oil and gas exploration.
