摘要:

通过理论模型研究,推导出了走滑拉分盆地中盆地的走滑速率与沉降速率之间的关系,即走滑速率同盆地的几何形状参数、最大沉降深度和沉降速率存在着稳定的数值关系。以莱州湾地区潍北凹陷为研究对象,利用回剥法对凹陷内处于不同构造位置的4口井的基底沉降历史进行了恢复,建立了潍北凹陷沉降速率与郯庐断裂中段走滑速率之间的经验关系式;根据位于洼陷带的伪1井和央5井的计算结果,得出郯庐断裂中段新生代右行走滑位移量为40 km左右。

关键词: 走滑位移, 沉降分析, 拉分盆地, 郯庐断裂带

Abstract:

The formula between strike-slip rate and subsidence rate in the pull-apart basin is derived by doing theoretical model studies. The result shows that the strike-slip moving rate has a steady relationship with the geometric parameters, the maximal subsidence depth and the subsidence rate. The Weibei sag in the Laizhou Bay is selected as the study area. Four wells in different structural positions of the Weibei sag are chosen to do subsidence history reconstruction using the back-stripping method and the empirical relationship between Tan-Lu fault strike-slip rate and Weibei sag subsidence rate is obtained. According to the calculating results of the wells Wei 1 and Yang 5 in the north depression, it is concluded that the Cenozoic dextral strike-slip displacements of the Middle Tan-Lu fault in the Laizhou Bay is about 40km.

Key words: Strike-slip displacement, Subsidence analysis, Pull-apart basin, Tan-Lu fault.
