外围油田常规降粘方法主要有水泥车循环洗井,加药降粘和超导热洗三种方式,通过近几年的加药降粘效果来看,常规加药降粘效果不甚明显,而水泥车循环洗井和超导热洗降粘效果有限,以升平油田生产实际为例,分析和对比了三种加药方法优缺点,摸索出了延长加药热洗周期方法,总结出适合本油田的两种综合降粘方法。 Peripheral oilfield conventional method of viscosity reduction are mainly cement tank circulating well washing, drug dosing and superconducting heat washing in three ways, through the drug in recent years, the viscosity reducing effect point of view, the conventional dosing viscosity reducing effect is not obvious, The cement truck circulating washing and superconducting thermal desorption viscosity reduction effect is limited to Shengping oil field production as an example, analyzed and compared the advantages and disadvantages of the three dosing methods, worked out to extend the dosing hot cleaning cycle method, summed up to fit Two integrated methods of viscosity reduction in this field.
