摘要
介绍并分析了新店油田葡萄花油层边水推进快,含水上升率增大,从而影响油田开发效果的现状。采取了有针对性的边水治理措施,即合理控制生产压差和采油速度,完善注采关系。治理后,葡萄花油层水侵系数由0.0624×104m3/(月·MPa)下降到0.0489×104m3/(月·MPa),水侵速度由0.4659×104m3/月下降到0.3921×104m3/月,油田综合含水上升率由1.92%下降到1.75%。
The current situations are rapid advance of edge water,accelerating increase of water cut and harming development effects in Putaohua oil reservoir of Xindian oilfield.Some objective measures to treat edge water have been adopted ,including reasonably controlling production pressure drawdown and oil recovery rate and improving a relationship between injection and recovery.After this treatment,water encroachment factor decreased from 0.0624×10gm^3/（month·MPa） to 0.0489×104m^3/（month·MPa）,water influx rate from 0.4659x 104m3/month to 0.3921×10^4m^3/month and comprehensive acceleration rate of water cut from 1.92% to 1.75% in the reservoir.
