Abstract:This paper demonstrates an example of strike-slip fault displacement calculation based on structure physical simulation.Using drilling data and seismic interpretation,a structural physical simulation of Liaozhong Sag is completed based on local faults and fault system characteristics.Three groups of fault patterns are involved,i.e.,two main parallel strike-slip faults,two main non-parallel strike-slip faults,and a single main strike-slip fault.The evolution and formation mechanism of the strike-slip faults are discussed and main strike-slip fault displacement is calculated.The following understandins are obtained:①Several geese and broom fault systems were developed in Liaozhong at the end of the LZ1 fault and upper layers of strike-slip faults,which were mainly controlled by the Oligocene right-lateral strike-slipping;②Geese and broom fault systems,and plane through fractures were formed with the increase of slip,geese and broom fault systems can be used as references for deep strike-slip fault interpretation; ③Based on quantitative statistical analysis,the ratio of extension to slip is about 3:2,the strongest strike-slipping of three main faults was in the Dongying Period,and the largest slip occurred at LZ1.
