在天然水驱和人工水驱油田的开发条件下,原油是通过水的驱替作用而流向井底的,因而油井的见水是一个不可避免的客观规律。由于水驱的作用,一方面可以保持油田的地层压力,实现油田的高产稳产和较高的采收率;另一方面,随着水线的推进和油井的逐步含水与水淹,必将引起油田含水的上升和产量的下降。因此,如何分析、研究和预测油田动态的变化规律,适时地采取必要的措施和对策,乃是一项重要课题之 Under the conditions of natural waterflooding and artificial waterflooding, the crude oil flows to the bottom of the well through the displacement of water, so the seepage of oil wells is an inevitable objective law. Because of water flooding, on the one hand, it can maintain the formation pressure in the oil field and achieve high and stable production and high oil recovery; on the other hand, as the water line progresses and the oil well gradually water and flooded, it will inevitably cause Oilfield water up and production decline. Therefore, how to analyze, study and forecast the law of the dynamic changes of the oilfield and take the necessary measures and countermeasures timely is an important issue
