A New Method for Evaluating the Water Drive Curve of Sandstone with Strong Bottom Water
School of Petroleum Engineering, Chongqing University of Science and Technology, Chongqing 401331, China
| Abstract: | Strong bottom water sandstone reservoirs are a type of reservoir with abundant natural energy. During the development process of reservoirs, water drive energy is the main source of energy. At the same time, there are also many problems that arise during water flooding, especially the problems of early water breakthrough and bottom water breakthrough. Through literature research and geological characteristics of the reservoir, combined with previous research on the region, it was found that water drive analysis of this type of reservoir is very necessary. This article mainly analyzes four classic water drive curves, as well as FW-Np and WOR-Np water drive curves, and fits single wells. The fitting effect is comprehensively evaluated using correlation coefficients, calculated values, and actual values. Through calculation, in the water drive characteristic curve, the difference in R2 is not significant when fitting the straight line segment. Relying solely on the correlation coefficient R2 cannot determine the adaptability of the water drive curve well. Therefore, the actual and calculated data are fitted, To comprehensively determine the suitable water drive curve for production wells. Most wells conform to Type A water drive curves, while some wells have good adaptability to Type C, Type D, and WOR-Np water drive curves. In the process of reservoir development, using water drive curves with good applicability, adjusting the development system, predicting the water content and cumulative water production of the reservoir, is beneficial for the development of the reservoir. |
