摘　　要：为改善开发效果,大庆外围油田开展了大范围井网加密调整,为了对已加密区块开发效果进行评价,引入中心逼近理想点法,并结合实例探讨了其在井网加密区块开发效果评价中的应用。结果表明,适合朝阳沟油田评价的8个加密效果评价指标为:提高采油速度倍数、综合递减率变化、提高水驱控制程度、提高水驱动用程度、含水上升率变化、提高采收率、地层压力保持水平变化、税后内部收益率。参数体系进行排序可知,二类区块加密效果最好,三类区块加密效果一般,一类区块加密效果最差,评价结果与利用开发数据分析的结果一致,为定量化评价井网加密区块开发效果提供了新的方法。In order to improve the development effect, Daqing peripheral oilfield has carried out a wide range of well pattern encryption adjustment. In order to evaluate the effect of the encrypted block development, the center approximation ideal point method is introduced, and the effect of the development of the well pattern In the application. The results show that the eight evaluation indexes for Chaoyanggou oilfield evaluation are as follows., increasing the speed of oil recovery, increasing the rate of comprehensive decline, improving the degree of water flood control, increasing the degree of water drive, increasing the rate of water rise, improving the oil recovery Pressure to maintain the level of change, after-tax internal rate of return. The results show that the encryption effect of the two types of blocks is the best, the encryption effect of the three types of blocks is the best, and the results of the evaluation are the same as those of the development data. The Mock development effect provides a new approach.
