We have developed key drilling technologies including "well factory" drilling pattern, oil base drilling fluid and elastic-tenacity cementing slurry system, logging technologies including conveying logging in the long horizontal casing and areal mud logging, fracturing and gas testing technologies including the joint operation of pumpdown bridge plug and perforating, and large scale staged fracturing technology in horizontal well, microseismic geometry designed to perform microseismic fracture monitoring, key equipment technologies including high-pressure & large-power fracturing units, "well factory" supporting drilling equipment, surface engineering construction technologies including loop & branch-shaped station layout and standardization construction.

We have developed four serial technologies including high acid gas reservoirs drilling technologies for safe, fast and premium drilling, well logging and surface logging technologies for complex conditions monitoring & prediction, high acid content gas well testing technologies for reservoirs efficient evaluation, high acid gas reservoirs surface engineering technologies centered for acid gas reservoirs environment protection and acid wet gas gathering & transmission facility construction. These four systems realized the high acid gas reservoirs E&D engineering technologies systemization, standardization, integration and industrialization. 112 patents are achieved and 485 standards are established. The output of natural gas and sulfur in Puguang and Yuanba gas fields reach 12 billion mᵌ and 2.7 million tons per year now.

We have developed integrated geological engineering design technology for improving the economic recoverable reserves of single well; fast and premium drilling technologies for horizontal wells like specific high efficiency bits, hole trajectory design and control and "wells factory" development pattern; complex reservoir well logging evaluation technologies that take reservoir response as characteristics; X-ray elements mud logging technology, horizontal well staged fracturing technologies for different well completion , until now more than 1700 wells have been drilled in Shengli oil field, Ordos basin, Western Sichuan, etc.

We have developed integrated well bore engineering technologies including seismic exploration technology, engineering construction technology, marine engineering equipment design and building technology, marine engineering surveying and position technology, dense cluster and extended reach well technology. Developed Three develop patterns are on beach and in shallow sea area, on the artificial island and on the shallow sea platform, ensure the shengli offshore oilfield sustainable development, the annual oil output reach to 3 million tons.

We have developed integrated technologies including low-cost and high-efficient drilling technology, well logging evaluation technology, optimized fracturing technology, quantitative production and drainage technology, construction technologies adapted to the "low pressure and low yield". Realized production capacity of 5 × 108m³ in southern Yanchuan CBM field -the first CBM field of Sinopec.

We have developed the technology of ultra-deep well design optimization, ultra-deep well drilling at quick speed, ultra-deep drilling fluid technology, ultra-deep cementing technology and ultra-deep well engineering supporting technology. Until now, more than 1350 ultra-deep wells have been completed among which more than 200 wells has depth over 7000m and 2 wells has depth over 8000m (MASHEN 1 with the depth of 8418m and TASHEN 1 with the depth of 8408m).
