Abstract: Petroleum engineering technology is the means to realize oil/gas exploration and development and also an important momentum for pushing the development of oil and gas industry. In order to achieve efficient exploration and development of complex oil/gas reservoirs and tap the remaining oil/gas and to meet urgent demands for petroleum engineering technologies, Sinopec has carried out technology research and development in fields of quick drilling and completion, wireline logging and mudlogging for complex formations, special formation stimulation, and also engaged in the development of matching equipment. These achievements provided strong support for the oil/gas exploration and development in over 70 basins and over 500 blocks, as well as for the oilfield technical service market exploration in nearly 40 countries. This paper presents the current development status of Sinopec’s petroleum engineering technologies, and highlights technical breakthroughs in drilling and completion, wireline logging, mudlogging and reservoir stimulation made by Sinopec. Considering the development goals of Sinopec petroleum engineering technologies and new demand for technologies, it also proposes to accelerate the development of core technologies and further improve technologies for ultra-deep oil/gas reservoirs, shale oil/gas reservoirs, tight oil/gas reservoirs, mature oilfield in east China,and give full attention to the technology esearch and development for unconventional energies and deep-water oil and gas.All these efforts will help to enhance the integrated service capacity of Sinopec.
