随着油田的开发,动用的层位越来越多,同时对应的注聚(注水)井就需要多层注水,以满足油田开发的需要。由于各层位的物性、能量等因素的差别,造成层间非均质性严重,往往不能满足地质动态调整的要求。为了达到注够水、注好水注好聚的目的,更好的扩大注聚效果,对层间差异大的注聚(水)井实施油套分注,改善吸水剖面,避免层间干扰,满足配注要求,保证动态调整有效实施,促使对应油井见效。
With the development of oilfields, more and more layers are used, and the corresponding injection (injection) well requires multiple layers of water injection to meet the needs of oilfield development. Due to the difference of physical property and energy of various layers, the interlayer heterogeneity is serious, which often can not meet the requirements of dynamic adjustment of geology. In order to achieve enough water injection, the purpose of water injection is good, the injection polymerization effect is better expanded, and the injection well (injection) of oil injection wells with large difference between layers is implemented to improve the water absorption profile and avoid interlayer interference. Meet the note requirements, to ensure the effective implementation of dynamic adjustment, prompting the corresponding wells effective.
