油田开发后期,地层能量降低,开采难度增大,产量下降,是目前影响老油区效益的一条重要因素。采用注水开采的方式可以提高地层能量,解决生产矛盾。传统的粗犷型注水方式针对性不强,往往事倍功半,达不到预期效果。临盘采油厂引入精细注水管理,通过对地层的研究,既节约了成本,又取得了良好的效果。 In the late stage of oilfield development, formation energy is reduced, exploitation difficulty is increased and output is decreased, which is an important factor that affects the efficiency of old oilfields at present. The use of water injection method can improve formation energy, solve production contradictions. The traditional rough type of water injection is not targeted, often less effective, can not achieve the desired results. Linpan oil production plant into the fine water management, through the study of the formation, not only saves costs, but also achieved good results.
