Advances and Prospects of Sinopec’s Petroleum Engineering Technology During“14th Five-Year Plan”Period

During the“14th Five-Year Plan”period, Sinopec achieved systematic breakthroughs in petroleum engineering technology through continuous technological research and systematic integration, strongly supporting China’s stable crude oil production and natural gas output growth. Major advancements in engineering technology include: the development of a drilling and completion technology system for ultra-deep and extra-deep wells, significantly improving drilling efficiency and safety under complex geological conditions and enabling a 10 000-meter drilling capability; the development of key technologies for drilling and completion of horizontal wells with ultra-long horizontal sections in shale oil and gas, promoting breakthroughs in exploration and cost-effective development of shale oil and gas resources; the large-scale application of engineering technologies for enhancing production and efficiency in mature oilfields, effectively supporting production increase and stabilization in high-water-cut oil and gas fields; the establishment of offshore engineering technologies such as intensive cluster drilling and extended-reach drilling, ensuring efficient development of shallow-water oil and gas resources; the realization of “water consumption without water extraction” large-scale geothermal development and million-ton-level CCUS full-chain capabilities in new energy engineering, opening new pathways for green and low-carbon transformation; the construction of intelligent drilling, completion, and fracturing platforms, leading the transformation of engineering operation models. During the “15th Five-Year Plan” period, Sinopec will focus on the fields of “two deeps and one unconventional” and “one mature and one new”, targeting high-end, intelligent, and green research directions. It will continue to conduct research on key engineering technologies such as development in extreme deep-earth environments, cost reduction and efficiency enhancement in unconventional resources, deep potential tapping in mature oilfields, integration of new energy, and digital transformation, providing core engineering technology support for strengthening the foundation of national energy security.
