中国石化新闻网讯 据油田技术7月6日报道，拥有719生产许可证的挪威Spirit Energy AS已经完成了对7321/8-2 S号油井的钻探工作。该井在Johan Castberg油田以北110 千米处和Hammerfest以北约310 千米处钻探。 在第一次勘探中，该井遇到厚度约30米的Stø组，含水砂岩层20 米，主要储层质量中等。Fruholmen组厚约120米，上部有多个含水砂岩层，共30米，储层质量中、差水平为主。在Snadd地层上部约80 米处钻井，仅遇到厚2 米的含水砂岩层，储层质量良好。 二次勘探目标在下白垩统（Kolje组）的淤泥和细砂中发现了石油的踪迹。这口井被归为干井。 邹勤 摘译自 油田技术 原文如下： Spirit Energy drills dry well in Barents Sea Spirit Energy Norway AS, operator of production licence 719, has concluded the drilling of wildcat well 7321/8-2 S. The well was drilled about 110 km north of the Johan Castberg field and about 310 km north of Hammerfest. In the primary exploration target, the well encountered the Stø Formation with a thickness of about 30 m, with water-bearing sandstone layers of 20 m, mainly with moderate reservoir quality. The Fruholmen Formation was about 120 m thick, with several water-bearing sandstone layers in the upper part of the formation, totalling 30 m, mainly with moderate to poor reservoir quality. About 80 m of the upper part of the Snadd Formation was drilled, but the only thing encountered was a water-bearing sandstone layer, 2 m thick and with good reservoir quality. The secondary exploration target encountered traces of petroleum in silt/fine sands in the Lower Cretaceous (the Kolje Formation). The well is classified as dry. |
