              Major Technology Development

              We adhered to problem-solving orientation and accelerated making breakthrough in key and frontier technologies. In E&P technology, we further developed enrichment theory and exploration technology for marine phase large and medium-sized gas fields in Sichuan Basin. The stable production technology for shale gas field supported the increasing production in Fuling gas field. The ultra-deep drilling and well completion technology facilitated the construction work in Shunbei ultra-deep well. In refining technology, we developed products such as low-sulfur bunker fuel, high-grade gasoline engine oil and diesel engine oil. In petrochemical technology, the industrial demonstration unit of the second generation highly-efficient environmental-friendly aromatics was successfully commissioned. The hydrogen peroxide production technology using anthraquinone method in slurry bed and the complete set technology of para-aramid were industrialized.
