摘　　要：注采参数是影响复合热载体吞吐采油现场试验效果关键因素之一.为了提高复合热载体吞吐采油的经济效益,依据复合热载体为两相三组分的流体特征,结合试验区油藏特点,以萨北过渡带的典型井B2-2-S90井为模拟井,利用数值模拟方法对复合热载体吞吐的注采参数进行了优化.结果表明：优化的措施半径为16 m,注入速度为9 000 m3/d,注入温度为310℃,焖井时间为9d,采液速度为39 m3/d.同时依据优化的注采参数开展了现场试验,试验取得了明显的增油效果,累计增油量739.7 t,有效期14个月.The parameters of the injection and production are one of the key factors of influencing the effects of the oil-production field test by means of combined heat carrier huff and puff. In order to enhance the economic profit of the huff and puff, with the help of the liquid characteristics of two phases and three components of the carrier, the optimization of the parameters is conducted by integrating with the reservoir properties of the tested area and taking the typical Well B2-2-S90 in Sabei transitional belt as a simulating example and moreover by means of the numeri- cal simulating method. The results show that the optimized treatment radius is 16 m, the injection rate is 9 000 m3/d, the injection temperature is 310 ℃, the well killing duration is 9 d, the liquid withdrawl rate is 39 m3/d. At the same time, according to the optimized parameters, the field test is launched, and moreover the oil incremen- tal effect is obvious, the accumulated incremental production is up to 739.7 t, the valid duration reaches 14 months.
