Professor Yao Jun is responsible for the achievement of Key Technology and Industrial Application of Multi-scale and Multi-mode Coupling Numerical Simulation of Complex Oil and Gas Reservoir, which is supported by more than 20 national and enterprise projects such as National 973 Plan Project and National Natural Science Foundation Key Project. In view of the characteristics of complex oil and gas reservoir such as spatial multi-scale, flow multi-mode and obvious multi-field coupling effect, traditional oil and gas seepage mathematical model and numerical simulation software are not applicable. For this, The academic idea of multi-scale correlation, multi-field coupling, combination of continuous and discrete media is put forward from the deep level of mechanical theory, the numerical simulation technology and real-time optimization method of complex oil and gas reservoir are established, and practical software is developed and applied in industry. The achievements have been popularized and applied in 15 oil and gas fields at home and abroad, supporting the construction of national shale gas demonstration areas and the efficient development of fractured and vuggy carbonate reservoirs in China.

Professor Hou Jian is responsible for the achievement of Deep slow release viscosity enhancement chemical flooding enhanced oil recovery technology, relying on the joint support of national outstanding youth science fund, general fund, national science and technology major special projects and other national and enterprise projects, aiming at the three key problems of low viscosity retention rate of displacement fluid, difficult start-up of remaining oil and low efficiency of chemical agent displacement in the chemical flooding process of old oil fields, after more than ten years of tackling key problems, he invented the water phase flow field control technology of capsule polymer deep slow release viscosity enhancement. The microcosmic seepage experimental device and simulation method of chemical flooding are developed, the corresponding numerical simulation software of chemical flooding reservoir is formed, and the method, device and system of channeling prevention are established. The results have been applied to 7 oilfields in China, and the effect of increasing oil production and reducing water is obvious.

Professor Li Binfei is responsible for the achievement of Key Technologies and Equipment for Low Carbon and Efficient Recovery of Heavy Oil by Steam Injection and Industrialization. Relying on the support of many major projects such as major national science and technology projects, he innovates the theory of low carbon enhanced thermal recovery of gas enhancing deep heat transfer and replacing viscosity reduction by hot gas in view of the large heat loss of heavy oil steam injection recovery, high steam consumption per ton, small viscosity reduction range by steam heating, prominent steam channeling problems, etc., and invents aerogel. Micro-nano particle reinforced foam system, created a series of methods for steam cavity expansion equilibrium regulation, innovated mixed gas dew point monitoring and corrosion control technology, developed mobile, skid-mounted integrated flue gas capture and treatment injection equipment, and built an industrial production line of equipment. The results have been applied to heavy oil fields in China, supporting the innovation and development of heavy oil and low carbon development technology and equipment in China.

Professor Huang Weian is responsible for the achievement of Key Environmental Protection Technologies and Large-scale Application of Water-based Drilling Fluid, supported by more than 20 research projects such as National Science and Technology Major Project, National Natural Science Foundation of China, PetroChina, Sinopec and CNOOC. In view of the low utilization degree of drilling waste resources and high cost, it is impossible to realize the environmental protection treatment problem covering the whole process pollution control of process reduction, terminal treatment and source control. We have developed equipment for solid phase control and solid-liquid separation of onshore drilling fluid, equipment for in-situ reduction and disposal of offshore drilling fluid waste, invented composite flocculant based on medium molecular weight cationic polymer, developed high-strength surface curing coating technology for water-based drilling cuttings, and invented environment-friendly treatment agent. 20 drilling fluid recovery and treatment stations, 1 harmless treatment experimental base and more than 5000 wells have been built in domestic oilfields by applying this technology.
