The key technology for the exploration and development of ultra-deep fault-controlled and fractured-cavernous oil and gas reservoirs was continuously iterated to provide strong support for the engineering of Project Deep Earth No.1. The shale gas exploration of complex structure zone was integrated in the margin of southeastern Sichuan Basin, and the exploration of Cambrian new type shale gas in western Sichuan obtained major breakthrough for the first time in China, opening up a new front to scale up reserve in Sichuan and Chongqing Natural Gas Base as part of Project Deep Earth. We also developed a set of classification and evaluation standards for the “sweet spots” of continental shale oil in Jiyang Depression and Northern Jiangsu Basin, providing technical support for the megaton-scale production capacity construction in Jiyang Shale Oil National Demonstration Zone.

We successfully developed a complete set of low-sulfur heavy bunker fuel technology and obtained airworthiness certification for the independently-synthesized aviation engine lubricating oil. The independently-developed aerospace phase-change materials were applied to the support devices of Wentian lab module. We picked up pace to develop “fuel to specialty” products with multiple grades of special oil products commercialized.

The industrial unit using the third generation aromatic technology was competed and put into operation, and the crude cracking gas to ethylbenzene/styrene unit was successfully started up. The high-grade polybutene-1 industrial demonstration unit achieved continuous and stable operation, and the hydrogenated nitrile rubber industrial unit produced on-spec products. The 10000-tonne synthetic high-temperature thermal oil industrial unit was operated at full capacity with products applied in the national energy storage demonstration project.

We formed an intelligent safety control technology system for high acid gas fields and built a risk monitoring, warning, and control platform. We also successfully launched and operated the complete set of online real-time optimization (RTO) software for S-Zorb unit.
