摘要: 反韵律砂层油的运移二维模拟实验研究表明:(1)反韵律砂层在油的运移过程中表现为顶部含油饱和度高,含油厚度小,含油层段平均运聚效率高,含油饱和度具有从上到下逐步降低的特点 ;(2 )在反韵律砂层,油气的运移方向、路径和通道总体表现为自下而上,由复杂趋于简单,并主要受油气充注方向、充注速率和渗透率级差等条件的影响 ;(3)水动力既可以增加反韵律砂层油的运移效率,减小散失量,亦可以降低油的运移效率,增加散失量。注水速率较小时,可以增加反韵律砂层油的运移效率,但注水速率较大时,主要表现为降低油的运移效率 ;(4 )水动力作用降低了反韵律砂层中油的运移速率

Abstract: ExperimentaI study of oiI migration in coarsening upwards sands have carried out by 2-D experimentaI modeI. The foIIowing resuIts have been obtained：（1）Near the top of the coarsening upwards sands, the oiI saturation is higher, the thickness of oiI sand is smaIIer, and the average efficiency of oiI migration in the parts of oiI-bearing sands is higher. In the sands the oiI saturation is decreasing downwards;（2）The direction and pathway of oiI migration generaIIy become more simpIe upwards in coarsening upwards sands and they are mainIy depended by the rate and direction of oiI injection, the permeabiIity difference of carrier beds and so on;（3）Hydrodynamics not onIy increase the efficiency of oiI migration but aIso decrease it. When the rate of water injection is Iow, hydrodynamics can increase the efficiency of oiI migration, whereas it wiII decrease the efficiency of oiI migration;（4）Hydrodynamics can decrease the rate of oiI migration.
