Abstract: Bohai Oilfield is an important support for increasing offshore oil and gas reserves and production in China. In view of the complex geological conditions,the coexistence of multiple pressure systemspoor wellbore stabilityhighly risky drilling operationand the great difficulty in comprehensively improving inefficient wells in Bohai Oilfieldan analysis and study of the system of innovative technologies to improve drilling speed and efficiency are conducted with safe drilling operation as the criterion. These technologies have been applied successfully in fieldwhich include the wellbore stability study-based extreme extending techology for ERWthe technology of twin holes in monobore to use the slot more efficientlythe well structure optimization technology to minimize casing stages and sizesthe dynamic comprehensive analysis and optimization technology for coated tubularsand the decision-tree model-based refined sidetracking technology. The future development trend of reducing cost and increasing efficiency for drilling in Bohai Oilfield is also looked into in order to provide technical reference for the efficient development of Bohai Oilfield. 

Key words:
