Widely applied in the sandstone reservoir, Tong’s chart board can estimate the recoverable reserves, calibrate the oil recovery, and predict the water cut of waterflooded sandstone reservoirs. The characteristics of water drive of conglomerate reservoirs which has the intricate mode pore structure and severe heterogeneity are obviously different from sandstone reservoirs, and the adaptability of Tong’s chart is poor. Based on the actual data of several conglomerate reservoirs in the northwestern margin of the Junggar Basin, through drawing the A-type water drive curve and taking the slope of the straight line of stable waterflooding period data, analyzing the relationship between B value and block geological reserves, and the empirical constant M of 8.65 is obtained, which is more consistent with the water drive curve characteristics of conglomerate reservoirs. The generalized water drive chart (GWDC) of conglomerate reservoirs is established by introducing the water and oil ratio correction coefficient c which is introduced in the formula of Tong’s chart and combining the empirical constant M. Based on the example of the Bai 21 blocks in Baikouquan Oil Field, it is proved that the conglomerate water drive chart proposed in this study can successfully reflect the characteristics of the waterflooding development of the conglomerate reservoir, and has guiding significance for the index prediction of the waterflooding development in the middle-late stage of the conglomerate reservoir.
