Aker BP在挪威海发现少量油气

    中国石化新闻网讯 据离岸工程网站11月12日消息 挪威石油公司Aker BP在挪威海发现少量石油和天然气。

    根据挪威石油管理局的消息，Aker BP ASA作为127 C生产许可证的运营商，已经完成了对6607/12-4和6607/12-4 A评价井的钻探。

    这些井是在挪威海北部发现的6607/12-2S（Alve Nord）天然气和石油发现地东北方向约7公里处和Br?nn?ysund以西200公里处钻探。

    6607/12-4井的主要勘探目标是证实侏罗纪/三叠纪（Garn、Ile、Tofte、Tilje和?re组）储层岩石中的石油。二次勘探目标是探明早白垩世（兰格组）储集层中的石油。

    在初步勘探目标中，该井在Garn、Not和Ile组共遇到80米气柱，其中45米位于储层质量较差的砂岩层。在侏罗纪/三叠纪的其他地层中，砂岩层含水层，储层质量中等至较差。

    在二次勘探目标中，该井在兰格组的三个储层带中遇到了石油。在上部区域，油层质量较差至中等的2米砂岩层；中部区域，5米砂岩层，储层质量中等至良好；下部区域，3米砂岩层，储层质量较差至中等。没有遇到油/水接触。

    Aker BP Makes Minor Oil and Gas Discovery in Norwegian Sea

    Norwegian oil and company Aker BP has made a minor oil and gas discovery in the Norwegian Sea.

    According to the Norwegian Petroleum Directorate, Aker BP ASA, as the operator of the production licence 127 C, has concluded the drilling of wildcat well 6607/12-4 and appraisal well 6607/12-4 A.

    The wells were drilled about 7 kilometers northeast of the 6607/12-2 S (Alve Nord) gas and oil discovery in the northern part of the Norwegian Sea and 200 kilometres west of Br?nn?ysund.

    The primary exploration target for well 6607/12-4 was to prove petroleum in reservoir rocks from the Jurassic/Triassic Age (the Garn, Ile, Tofte, Tilje and ?re Formations). The secondary exploration target was to prove petroleum in reservoir rocks from the Early Cretaceous Age (the Lange Formation).

    In the primary exploration target, the well encountered a total gas column of 80 meters in the Garn, Not and Ile Formations, 45 meters of which in sandstone layers with poor reservoir quality. In the other formations from the Jurassic/Triassic Age, the sandstone layers are aquiferous with moderate to poor reservoir quality.

    In the secondary exploration target, the well encountered oil in three reservoir zones in the Lange Formation. In the upper zone, oil was encountered in a 2-meter sandstone layer with poor to moderate reservoir quality; in the middle zone in a 5-meter sandstone layer with moderate to good reservoir quality and in the lower zone in a 3-meter sandstone layer with poor to moderate reservoir quality. No oil/water contacts were encountered.
