摘要
Based on the fault activity analysis and the development phase, the faults affecting the red-bedding series can be divided into three systems: pre-deposition, deposition and post-deposition of Ek-Lower Es4. The fault systems formed during the red-bedding series deposition display as the succession and reformation of the former NW fracture system, and its development characteristics control the Ek-Lower Es4 prototype basin. The analysis on development characteristics of fault system has an important meaning for realizing the distribution of red-bedding reservoir in Dongying Depression.
