摘　　要：在油田开发晚期为了避免油井产量大幅度下降,考虑了日月涨潮现象,进行了油田注水调整和地层的振动处理,在降低注水量的同时也节约50%的电能,最终增加油井产油量,提高油田采收率。采用可导致地层水力变形的局部注水和提高注水地层波及率的新工艺,进一步提高了开发晚期油田的原油产量和采收率。In order to avoid significant decline of oil production in the late of the oilfield development. Considering the sun and the moon high tide phenomenon and the oilfield water injection and the formation of vibration treatment were done. Water injection was lower than before and at the same time had a 50% energy savings. Finally increased oil production and enhanced oil recovery. Used localized water injection which can lead to the formation of hydraulic deformation and used new technology which can increase the rate of formation spread. Further improve the development of late oil field crude oil production and recovery.
