Monitoring technique and application of reservoir,case and wellsite facilities which oilfield development mainly concerns are introduced.
文章介绍了油气开发中主要关心的油气藏、井场设备及套管的监测技术和运用效果,油气藏监测主要是剩余油和油藏储藏物性的监测,套损直接影响油、水井的使用寿命、油、气产量和注水效果,井场设备运行的好坏直接关系油、气产量和注水效果,输油(注水)管道泄漏造成资源的浪费、人身伤害和环境污染事故。
Accord to high water containing developing period of Daqing oilfield and actual situation of case damaged seriously in water and oil wells, a set of explosive perforation tech for cased well is introduced.
针对大庆油田开发进入高含水开采阶段,油水井套管损坏显著加快的实际情况,介绍了套损井爆炸打通道工艺技术。
Injection unbalance caused by case damaged not only effects unsteady of oil field production, but also brings about oil-water well stopped, discarded which makes it unusually conduct of normal operation.
玉门油田在注水开发过程中,油水井套管损坏情况非常严重。
