Abstract: In recent years, Sinopec Oilfield Service Corporation continued to make study of the key petroleum engineering technology, improve the related equipment and focus on the information development direction to modernize a variety of technologies. In the light of the petroleum engineering objectives to“ improve quality, speed, efficiency and production”, this article elaborates a series of petroleum engineering technological achievements as result of “four improvements”, such as rotary steering,casing drilling, drilling string automation equipment, re-construction of wellbore, and re-fracturing. Significant progress was also made in engineering quality, drilling speed, service efficiency, and production from oil and gas wells, effectively supporting exploration and development of deep and ultra-deep layers and unconventional and low-graded oil and gas resources. With the exploration targets becoming increasingly complicated and development increasingly difficult, it is necessary to further promote highefficiency and high-quality development of oil and gas resources by means of technological innovation and equipment modernization. Based on the existing theories and practice, it is proposed to make efforts for cross-disciplinary integration and empowering, develop disruptive technologies and couple professional information knowledge to re-accelerate improvement of petroleum engineering technologies.
