古城油田B124区普通稠油注水开发目前已进入中高含水期开发阶段,油层非均质性严重,平剖面矛盾突出,在注水开发过程中油田含水上升速度加快,地层压力保持水平低,稳产难度大。要通过综合治理,进一步完善注采井网,细分注水,改善水井吸水剖面,适时动态调配,确定合理注采比,逐步提高地层压力,保持稳产。 At present, the injection of heavy oil in B124 area of ​​Gucheng Oilfield has entered into the development stage of middle and high water cut stage. The reservoir heterogeneity is serious and the flat profile is contradictory. During the process of water injection development, the water cut of oilfield is accelerated, the pressure of formation is kept low, . Through comprehensive management, we should further improve the well pattern of injection and production wells, subdivide water injection and improve the water absorption profile of wells, and timely and dynamically allocate them to determine a reasonable injection-production ratio and gradually raise the pressure of formation to maintain stable production.
