摘要
新疆油田百口泉某区块已进入中高含水期,确定油藏在注水开发过程中的配注量或注采比,对于稳定原油产量、控制含水上升率、实现油田合理高效开发具有十分重要的意义.应用油藏工程方法中广泛使用的水驱特征曲线公式推导出了新的注采比随含水率变化预测模型,与传统注水配注计算方法相比,其使用限制条件简单,适用范围广,给定未来某一时刻含水率就能确定其合理注采比,且只需较少生产数据,参数求取方法简便,对于静、动态参数录取较少的区块特别适用.通过实例计算分析表明,该方法应用效果很好,可在其他区块推广使用.
Abstract
The Baikouquan oilfield in Junggar basin has faced with high water cut stage. In such waterflooding process, determination of water allocation quantity or injection-production ratio is of great significance for keeping oil production stable, controlling water cut and realizing reasonable and effective oilfield development. Using the formulae for waterflooding characteristic curves, the predicting model for injection-production ratio changing with water cut is established. Comparing with the traditional water allocation calculation method, it is characterized by simple limited condition and wide applied range. By given a future water cut, the suitable injection-production ratio can be determined. Its fewer production data requirement and simple calculation method are particularly suitable for the reservoir or block which has less static and dynamic production parameters. Case study shows that this method could be applied to other blocks in this oilfield.
