Abstract
Based on the present drilling situation of Zhenjing oilfield,the paper systematically introduced the main technology measures of drilling engineering,analyzed the technical difficulties of high quality and high speed drilling: drilling well leakage,borehole stability,optimization of directional drilling technology,maintenance of resistance to salt erosion by potassium amine group polymer drilling fluid and leakproof by steady pressure well cementing.According to the drilling practice,the high quality and high speed drilling was put forward,which could be the reference to the drilling construction in Zhenjing oilfield.
