ST. PETERSBURG, Russia消息 — Gazpromneft公司的子公司—Gazpromneft Shelf公司在Prirazlomnoye油田开凿了第一口回灌井，Prirazlomnoye油田位于Barents海，而Gazpromneft Shelf公司一直是Barents海地区开发项目的引领者。根据该油田的发展计划，这口回灌井将被用于回灌油井建造过程中产生的废弃物。
回灌工程将在产油层之上进行，以保证该工程能受到上下岩层的保护。抽水井将会促进工业废物循环，在不对环境造成破坏的情况下，这些工业废物将会被直接用于油田运营。
该采油平台已经安装了“零排放”系统，从而防止任何生产或钻井过程中产生的废物排放到大海之中。这些生产废物将会直接被回灌到岩层之中，或是运回岸上进行废物再利用。
目前，Prirazlomnoye油田上有两口采油井和一口回灌井处于运行状态中。而该油田计划总共开凿运营32口油井。自投产以来，Prirazlomnoye油田已累计生产1000万桶石油。
Gazprom Neft 公司的常务董事Gennady Lubin表示：“这口井极大地提升了油田工程的安全性和经济效益，同时也降低了管理难度。建造这口井的主要是为了直接在采油平台上对废弃物进行再利用。此外，我们还把废弃物运回岸上以降低成本。”石油圈原创www.oilsns.com

ST. PETERSBURG, Russia — Gazpromneft Shelf, a subsidiary of Gazprom Neft, has commissioned the first reinjection well at Prirazlomnoye field in the Barents Sea, on which it is leading development. Consistent with the field development plan, this will be used for the re-injection of waste materials produced during well construction.
Injection will take place into strata above the production horizon, ensuring its protection from higher and underlying layers. The absorption well will optimize the recycling of industrial wastes, which will now be utilized directly at the field with no negative environmental impacts.
A “zero emissions” system has been integrated into the platform to prevent the discharge of any production or drilling waste into the sea, with waste, instead, re-injected directly into the strata, or transported onshore for recycling.
Two production wells are currently in operation at the field, together with the injection well. The project envisages the commissioning of a total 32 wells. More than 10 MMbbl of oil have now been produced at Prirazlmnoye field since the start of production.
“The absorption well significantly improves the security, manageability and cost-effectiveness of the project. Making possible the direct recycling of waste directly on the platform, with no impact on the environment, is its main purpose. Added to which, we are reducing costs by transporting waste onshore,” said Gennady Lubin, executive director, Gazpromneft Shelf.
