本文针对萨北开发区葡II、高台子油层沉积特点及高含水后期剩余油分布特点,以周期注水原理为依据,并结合数值模拟理论研究成果对萨北开发区处于高含水后期的葡II、高台子油层实施周期注水,取得了较好的效果,对萨北开发区葡II、高台子油层高含水后期周期注水方法推广应用具有指导作用。 In this paper, according to the sedimentary characteristics of the Portuguese II and Gaotaizi reservoirs in Sabi Development Zone and the remaining oil distribution characteristics in the later period of high water cut, based on the principle of periodic water injection and the results of numerical simulation, The Gaotaizi reservoir is filled with periodic water and has achieved good results. It has a guiding role in the promotion and application of the periodic waterflooding method in the later stage of high water cut in Portai II and Gaotaizi reservoirs in the Saibei Development Zone.
