低渗透油藏在实行注水开发过程中,注入水容易沿着渗透性较好的方向突进,导致对应油井含水上升快或者难以见到注水效果,而相对低渗透层吸水量较少,甚至不吸水。利用注入剖面测试技术,结合油水井动静态资料能够从纵向和横向了解油层的吸水状况、注水波及特征及储量动用情况。再结合相关资料对油水井作出及时的调整措施,达到提高该油藏注水效率和区块稳产的目的。
During the development of waterflooding, the injected water tends to protrude in the direction of better permeability, resulting in the rise of water corresponding to the well or the effect of water injection, while the water in the relatively low permeability layer has less water absorption or even no water absorption . By using the injection profile test technology and the dynamic and static data of oil and water wells, it is possible to understand the water absorption status, water injection characteristics and reserves utilization of the oil reservoir both vertically and horizontally. Combined with relevant information on oil and water wells to make timely adjustment measures to improve the efficiency of the reservoir water injection and block the purpose of stability.
