The basement of Bohai Bay Basin suffered different extension and compression through two phases Indo-China movement and three phases Yanshan Movement in Mesozoic Era, which controls the stratum assemblages and structural styles in basement. Based on the previous achievements and data of exploration, the tectonic evolution in Mesozoic Era has been studied, the results show that the second stage of Indo-China Movement and the second stage of Yanshan Movement are the key tectonic periods which make the differences of the basement structure. The influence of the Paleo-asiatic tectonic domain in north, Paleotethys tectonic donmain in south, Pacific tectonic domain in southeast and the active of the Taihang Mountain fault, Yanshan-Lanliao fault, Tan-Lu fault responsible for the four zones of different basement structure which are west uplifted structure zone, middle reversed structure zone, east-north striked structure zone and south depressed structure zone. West uplifted structure zone and east-north striked structure zone with thinner compartment are easier to form high quality reservoirs and windows for hydrocarbon, whose buried hill hydrocarbon enriched in all of the sag and with a big reverses percentage, while middle reversed structure zone and south depressed structure zone whose buried hill hydrocarbon almost enriched along the sag edges are relatively poor in buried hill hydrocarbon accumulation.
