摘　　要：由于在实际生产中,天然能量开发强边水重油油藏表现出不同于普通边水油藏及热采稠油油藏的开发规律。因此,利用油藏工程方法等手段对哥伦比亚C油田的开发特征进行深入分析研究。结果表明,水体能量是影响该类油藏开发特征的主要因素;油田中低含水期含水率上升快,高含水期是主要产油期;受原油重度影响,油井在生产过程中易发生含水率突升、产油量突降;随着含水率上升,油田的采液指数上升,高含水期可通过提液增加油井产量。During the actual production of oilfields,the development of strong-edge water heavy-oil reservoirs was different from that of ordinary reservoirs with edge water and heavy oil,in this article,the reservoir engineering and other methods were used to analyze and study the development characteristics of C Oilfield in Colombia.The results show that water energy is the main factor affecting the development characteristics of such reservoirs.Water cut rises rapidly during its early period,and the high water cut stage is the main production period.The production wells are likely to occur that water sudden rises and oil decreases due to API gravity during production.With the increase of water cut,the liquid productivity index of heavy oil reservoir also increases,and oil production can be raised by increasing liquid quantity during high water cut period.
