摘　　要：X油田扶余区块采出液具有凝固点高、黏度大、低温流动性差的特点,易造成集输系统设备设施结蜡结垢等问题加剧,同时扶余井与水驱井共同集输模式使得集输温度整体升高,加大了节能降耗工作难度。通过区块采出液集输方法研究:一是开展关于凝固点、粘壁温度、冷输模式的现场运行试验对比,明确了凝固点作为油井最高集输进间临界温度的管理思路;二是优化调整集输运行思路,大平台建设模式下实现扶余区块与水驱区块分开管理,单井综合能耗相比零散井平均降低57.27%,在保障生产基础上降低运行能耗,以期为后续开发扶余区块地面系统运行管理方法提供指导。The produced liquid in Fuyu block of X oilfield has the characteristics of high freezing point,high viscosity and poor low-temperature fluidity,which is easy to aggravate problems such as wax and scale formation of equipment and facilities of gathering and transportation system.Meanwhile,the common gathering and transportation mode of Fuyu well and water flooding well increases the overall temperature of gathering and transportation,which increases the difficulty of energy conserva-tion and consumption reduction.Through research on the gathering and transportation methods of pro-duced liquid in the block,the field operation test comparison on the freezing point,sticky wall tem-perature and cold transport mode has been carried out,which clarifies the management idea of solidifi-cation point as the critical temperature between the highest gathering and transportation of the oil well.The ideas of gathering and transportation operation are optimized and adjusted.Under the mode of large platform construction,Fuyu block and water flooding block are managed separately.Compared with fragmented wells,the comprehensive energy consumption of single well is reduced by 57.27%on aver-age,and the operation energy consumption of a single well is reduced on the basis of ensuring produc-tion to provide guidance for the subsequent development of the ground system operation management method of Fuyu block.
