Representative Achievements

1、Dynamic monitoring technology of remaining oil in high water cut oilfield

The dynamic monitoring technology of remaining oil in high water cut oilfield is an important technical means in the tertiary oil recovery stage. Through this technology, the migration law of oil and water in reservoir can be dynamically monitored, and the oil-water interface, water flooding and water string in reservoir can be understood. This technology not only provides important guidance for the implementation of tertiary oil recovery technology scheme, but also provides guidance for the reasonable and effective development of oilfield It provides an important scientific basis for making the development plan of high water cut oilfield economically and searching for the distribution of remaining oil. The project is supported by the 863 plan during the 11th Five-Year Plan.

2、High sensitivity broadband electromagnetic sensor technology

High sensitivity and wide-band inductive electromagnetic sensor is the core equipment in electromagnetic exploration. Its technical performance directly affects the results of electromagnetic exploration. For a long time, China's electromagnetic exploration instruments and equipment are heavily dependent on foreign imports, especially high-performance electromagnetic sensors, which are monopolized by a few foreign companies. These electromagnetic sensors are not only expensive, but also take strict export control on individual models. This will greatly reduce China's voice in the field of electromagnetic exploration technology, but also seriously restrict the further development of China's electromagnetic exploration technology. In view of this situation, the subject focuses on the research and development of magnetic core materials, assembly technology, detection technology, etc., forming a set of manufacturing technology with independent intellectual property rights of high sensitivity and broadband electromagnetic sensor, and realizing the industrialization promotion of scientific research products, so as to further promote the development of electromagnetic exploration technology in China. The project is supported by the 863 plan during the 12th Five-Year Plan.
