大庆油田基础井网全面转抽后稳产途径的探讨

依据杏树岗油田北部的生产数据,采用历史拟合、数理统计等方法,分别整理出采液指数和吸水指数与含水率、地层压力、流动压力、注水压力等因素的定量关系。提出了大庆油田基础井网全面转抽后高含水期的稳产途径是:以不断提高产液量为中心,通过强化注水系统恢复和保持地层压力,在较高压力下保持注采平衡,并在不断提高产液量的过程中,加强分层注采强度的调整,控制含水上升速度。

DISCUSSION ON PRODUCTION STABILIZATION METHODS IN DAQING OIEFIELD AFTER FINISHING FLOWING-TO-PUMPING CONVERSION OF WELLS IN ITS BASTC WELL PATTERNS

According to the production data of the northern part of Xingshugang oilfield, using historical fitting method, methmatical statistic method, etc,tcthis paper systematizes out respectively the quantitative relationships between liquid production index, water absorption index and water cut, stratum pressure, ilowing pressure, water injection pressure and other factors,Thus proposes that during the high water cut period in Daqing oilfield, after the basic well patterns have been turned completely to production by artificial lift, the production stabilization methods are,taking inereasing the amount of liquid output continuously as a key, recovering and maintaning the stratum pressure through intensification of the water injection system, preserving the injection-production ballance under a rather higher pressure, and during increasing the liquid oulpul unceasingly, strengthening the regulation for the intensity of injection and production by layer and controling the water cut increasing rate..
