化学调剖技术,是在较低的注入压力下,利用非均质油层不同的启动压力,注入化学调剖剂,使之优先进入启动压力较低的高渗透层,当药剂凝固或膨胀后,降低地层的渗透率,从而降低高渗透层的吸水能力,限制高含水和强水淹层的吸水量,提高中低渗透层和低水淹部位的注水量,达到调整吸水剖面的目的。本文主要探讨调剖技术在注入开发油藏的应用。 Chemical profile control technology, at a lower injection pressure, the use of heterogeneous oil layer of the different start-up pressure, injection of chemical profile control agent, make it into the lower start-up pressure of high permeability layer, when the agent solidified or expanded, Reduce the permeability of the formation, thereby reducing the water absorption capacity of the high permeability layer, limiting the water absorption of high water and strong water flooded layer, improve the water infiltration of middle and low permeability layer and low flooding site, to achieve the purpose of adjusting the water absorption profile. This paper mainly discusses the application of profile control technology in the development of reservoirs.
