吸水剖面资料在低渗透油藏开发中的应用

在低渗透性油藏的注水开发过程中,由于存在层间、层内、平面的三大矛盾,以及裂缝的存在,注入水主要沿着渗透性较好的方向单向突进,而相对低渗透层则吸水量较少或不吸水,对应油井变化是含水上升快和难以见到注水效果两极差异。利用吸水剖面测试技术,结合油水井动、静态资料可以从纵向上和横向上了解油层的吸水状况、水驱方向和注水波及特征。结合相关资料能对油水井作出及时的调整措施,达到提高注水效率和区块稳产的目的。

In low permeable oil deposit water-injection development process, as a result of in existence level, level, plane three big contradictory, as well as crack existence, flood water mainly along permeable good direction unidirectional advance, but relatively low filter layer then the soakage are few or does not absorb water, corresponds the oil well change is the watery rises quick and sees the irrigation effect two-pole difference with difficulty.Using the entry profile test technology, the union oil water we...
