摘要

This paper summarizes the latest achievements and technological progress in oil and gas production engineering of China National Petroleum Corporation(CNPC) and discusses the main four challenges faced: developing low quality resource at low oil price;keeping stable production of mature oilfields when well oil production drops year by year;low systematic efficiency, high cost, prominent environmental protection issue and short of technological strategy for high water cut ratio and high oil recovery ratio oilfields;and lacking of high level horizontal well drilling and completion technology to develop unconventional and deep reservoirs. Three technological development directions to address these challenges are put forward: developing fracture controlling stimulation and well factory to produce low quality resource economically, developing re-fracturing technology for old wells in mature oilfields, promoting the fourth generation separate layer water injection technology to stabilize the production of mature oilfields;innovating new technologies of water flooding with nano-material, injecting and producing through one well.
