摘要
腰英台油田为中低孔特低渗天然微裂缝发育油藏,通过对注水开发过程中油井见效见水的规律性总结,研究分析见效见水的主控因素是受裂缝及沉积微相的影响,注入水方向性推进特征明显。这一研究成果对指导油田下一步高效注水开发具有极其重要意义。
Yaoyingtai oilfield is one with low-medium porosity, extra-low permeability and natural micro-fractures. By summariz- ing the effectiveness rules of waterflood response during the development, this paper pointed out that the controlling factors of water- flood response were mainly influenced by fracture and sedimentary microfacies and the characteristics of directional propulsion by injected water were obvious. The study is of great significance in guiding the effective waterflood development of oilfields in future.
