Development and Opinions of Chemical EOR Technology for High-temperature and High-Salinity Reservoirs Sun Huanquan 2021, 40(2): 1-7.  DOI: 10.3969/j.issn.1002-302x.2021.02.001 Abstract ( )   PDF (2331KB) ( )   Most of the mature oilfields in East China came under the ultra-high water-cut development stage. Further improvement of oil recovery is a stern challenge. Based on the practice from technological innovation and application both inside and outside China, it is confirmed that chemical flooding technology is able to substantially improve EOR of the ultra-high water-cut oilfields. The resources owned by Sinopec for chemical flooding are the high-temperature and high-salinity heavy oil reservoirs which are of the lacustrine facies and high heterogeneity, therefore it is difficult to apply chemical flooding. Focusing on substantial improvement of oil recovery, this paper elaborates the development process and application results of the chemical flooding technology that mainly includes polymer flooding, alkali-free surfactant-polymer flooding and heterogeneous composition flooding. A series of technologies has been developed on the basis of continual scientific research, which leads the world as a whole. The geological reserves of 17.6×108t have been implemented under chemical flooding development by the end of 2020. The annual production reached 1400×108t, showing that the EOR technology plays an important role in cost-effectively keeping production of the mature oilfields stable. Chemical flooding will be extended into the oil reservoirs with a higher temperature, a higher salinity and a higher viscosity in the next period of time. The surface engineering of chemical flooding is developing towards standardization, modulization and informatization. Cost-effectiveness and green development are the inevitable trends for enhancement of chemical flooding technological competitiveness.

Enhance Research on Reserves in Oil and Gas Exploration and Development Integration Zhang Kang, Zhang Liqin 2021, 40(2): 16-22.  DOI: 10.3969/j.issn.1002-302x.2021.02.003 Abstract ( )   PDF (2042KB) ( )   The upstream sector of the petroleum industry is divided into two stages -- exploration and development. The geological reserves proven in the exploration stage only reflect the preliminary and static knowledge about the oil and gas fields. China usually makes public its exploration achievements in terms of the static geological reserves. However, this may make outsiders misunderstand the oil and gas industrial situation. In the development stage, the reserves should be produced at maximum for economic benefits on the basis of deeply understanding the dynamic state of the hydrocarbon accumulation. In addition exploration should be supplemented to verify and increase the previous knowledge about the reserves. In recent years, China’s oil and gas imports have risen with the decline of the country’s oil production. However, the proportion of the proven non-produced geological reserves to the proven geological reserves is increasingly high in the reserves table, indicating that the reserves system reflected in the current reserves table cannot entirely show the economic recoverability of the reserves. It is suggested that the reserves should be continually revised and supplemented. Particularly, it is necessary to make the more detailed and clearer specifications on identification of the oil and gas recoverability and clarification of the dynamic changes in the reserves in the development stage while completing the reserves specifications on unconventional oil and gas of the various kinds which already come under large-scale development.
