| 摘 要： | 目前,BZ油田S–1区块注采矛盾越来越明显,累计注水亏空量大,导致地层压力下降,地层压力保持水平低,油田开发效果差。为此,运用数值模拟法和Logisitic生命旋回数学模型,研究了不同含水条件下油田的合理注采比,并建立了不同含水率下合理注采比的图版。研究结果表明,利用Logisitic生命旋回数学模型求得S–1区块合理注采比为1.22;利用数值模拟模型求得合理注采比为1.2～1.3。

| Abstract: | At present, the contradiction between injection and production is becoming more obvious in S-1 block of BZ oilfield. The large accumulative water injection deficit leads to the decline of formation pressure, low formation pressure and poor oilfield development effect. Therefore, by using numerical simulation and Logisitic life cycle mathematical model, the reasonable injection-production ratio of oilfield under different water cut conditions was studied and the drawing plates of the reasonable injection-production ratio under different water cut conditions were established. The results show that the reasonable injection-production ratio of S-1 block obtained by Logisitic life cycle mathematical model is1.22, and the reasonable injection-production ratio obtained by numerical simulation model is 1.2～1.3. |
