摘　　要：标准的童氏图版已经被广泛应用于中高渗透率砂岩水驱油田的可采储量预测和采收率标定,以及水驱开发中后期含水率预测,但是对于具有复模态孔隙特征和严重非均质性的砾岩油藏适应性较差。根据准噶尔盆地西北缘71个砾岩区块实际生产动态数据,使用数理统计学方法,把经验系数7.5修正为8.65,引入水油比修正系数c,并建立砾岩油藏广义水驱图版。经过实例分析,证明砾岩油藏广义水驱图版对于百口泉油田砾岩区块适应性较好,并且对于整个西北缘砾岩油藏水驱开发具有指导意义。The standard Tongs Chart has been widely used for recoverable reserves estimation and recovery calibration,and water cut prediction of medium-high permeability sandstone oilfields in the middle-late period of waterflooding development,but for the conglomerate reservoirs which has the complex mode pore structure and severe heterogeneity,is less adaptable. Based on the actual production data of 71 conglomerate blocks in the northwestern margin of the Junggar Basin,the generalized water drive chart of the conglomerate reservoir was established by revising the empirical coefficient 7. 5 to 8. 65 using the method of mathematical statistics,and introducing the water-oil ratio correction coefficient. Through the instance analysis,it is proved that the generalized water drive chart of conglomerate reservoir is well adaptable to the conglomerate blocks in Baikouquan oilfield,and it is as well as instructive for the water flooding development of the conglomerate reservoirs in the northwestern margin of Junggar basin.
