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 high-efficiency 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.
