随着油田开发的不断深入,逐步进入高含水期。由于纵向非均质性的影响,各小层吸水状况存在较大差异,层间矛盾和平面矛盾不断加大,总体上厚层动用好,薄层动用差。有必要通过细分调整来提高各类油层的动用程度,改善注水效果。由于各油田的储层特征不同,有必要研究适合油田自身储层的界限,指导细分调整,挖掘油田细分注水的潜力,改善开发效果。
With the deepening of oilfield development, and gradually into the high water cut period. Due to the longitudinal heterogeneity, there is a big difference in the water absorption of each layer. The contradiction between layers and the contradiction between layers are increasing. Generally, the thick layers are well used and the thin layers are poorly used. It is necessary to adjust the subdivision to improve the utilization of various types of reservoirs to improve the water injection effect. Due to the different reservoir characteristics of different oilfields, it is necessary to study the boundaries suitable for the reservoir itself, guide subdivision adjustment, tap the potential of oilfield subdivision and injection, and improve the development effect.
