摘　　要：针对吴旗油田吴93区块低渗透油藏递减快、稳产难、采收率低的特点,采用了超前注水技术开发。在油藏研究基础上从水井注水时机、注水见效时间、注水压力、注水强度的确定4个方面对超前注水技术措施进行了阐述。该方法在吴旗油田实际生产中取得了明显效果,对吴旗油田低渗及特低渗透油藏的开发具有重要意义。同时对同类油田或区块的开发具有借鉴作用。In accordance with the features of low permeability, low abundance, fast declining, difficult to stabilize production, and low recovery factor, advanced water injection has been conducted in block wu93 of The wuqi oilfield. Based on the study in the reservoir ,this paper elaborates the measures of advanced water injection in aspects of the opportunity of water injection, the effective time of Water Injection, the proper pressure of water injection, the proper intensity of advanced water injection. This method has obtained an evident effect in the oil field production. The advanced water injection can enhance the level of developing low permeability reservoirs. The success of advanced injection development test may guide the development of similar oilfields or blocks.
