摘　　要：近年来,针对W13西块油藏井网适应性差,分层调剖堵水、高压分注、分层压裂、井况治理等方面缺乏配套措施,非主力层水驱动用程度低,油藏潜力得不到发挥,稳产基础薄弱等存在问题。开展了油藏描述和剩余油研究,室内和矿场试验,实行了细分重组、开发对象向非主力层转移、提高水驱采收率为目标的精细调整治理。进行文13西油藏"异常高温、高压、高矿化度"条件下的配套工艺技术攻关,攻克深层开窗侧钻、大修、高压分注、分层改造等技术,实现了油藏有效开发动用,实现了年产油稳定、综合含水下降、采收率提高,取得了较好的经济效益。In recent years,for W13 West Block Reservoir WELL poor adaptability,layered EOR,high pressure dispensing,lack of supporting measures stratified fracturing,well conditions governance,driven by non-degree water main layer low reservoir potential not play,and stable foundation is weak,such as a problem.Launched a reservoir description and remaining oil,indoor and field test,the implementation of the subdivision restructuring,development of the object to the transfer of non-main layer,improve water flooding recovery as the goal of fine-tuning treatment.Man carried 13 West Reservoir supporting technology under the 'abnormally high temperature,high pressure,high salinity,' research conditions,overcome deep sidetracking,overhaul,high-pressure dispensing,layered transformation technology to achieve effective development of reservoir utilized to achieve an annual output of oil stable,comprehensive water drop,enhanced oil recovery,and achieved good economic results.
