%X 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.
