    Abstract: In recent years, Sinopec has maintained a commitment to intensivying the exploration & development of deep, ultra-deep strata, shale gas and tight oil and gas. In order to meet the needs of complex oil and gas exploration & development, Sinopec has developed a series of new oil well additives with high performance qualities. The additives include self-healing, nano-liquid silicon, and cover a wide temperature spectrum, are resistant to high temperatures. In addition, Sinopec has developed, high density and low density as well as elastoplastic cement slurry, and has formed the matching technology of ultra-deep well HTHP cementing, shale oil/gas cementing, as well as the ultra-long interval cementing with significant temperature difference. These new additives can also meet the cementing requirement under complex geological conditions, and promote the company’s oil and gas exploration & development process. Many new tools, equipment and products have been developed, including high-performance liner hangers, multiple stage cementers, automatic control cementing truck and integrated nitrogen foam cement slurry system, etc. Optimized cementing design software with independent intellectual property rights has been developed, so as to improve the level of domestic cementing technologies and core competitiveness. Going forward, the cementing technology development of Sinopec plans to adhere to the principle of demand-oriented product development, while maintaining a focus on the development trends of cementing for complex deep/ultra-deep wells, low-permeability and shale oil/gas, and complex pressure system technology for adjustment wells in old oilfields. Thus, the new technologies will better serve high-efficiency exploration & development of complex oil and gas reservoirs. At the same time, more effort will be directed to strengthen cross-disciplinary technology integration. In addition, Sinopec will research and develop new multi-functional, broad-spectrum, intelligent and integrated cementing materials, as well as cementing equipment to integrate with high-power, automation, intelligence, designing and monitoring.
