中国石化新闻网讯 据俄罗斯油气网Juschno-Sachalinsk,报道，作为其勘探战役的一部分，俄罗斯石油公司（俄油/Rosneft）日前成功地完成了位于萨哈林岛大陆架上的Vostochno-Pribrezhny许可证区块中的第一口勘探和评价井的钻井作业，发现了一个新的油田。 这口勘探井由俄油自己的钻井承包商RN-Burenie根据计划日期和所有安全和环保标准进行钻井作业。 作为钻井作业的一个结果，此井完钻时所测量的深度为3047米，垂向位移为1450米。在复杂的地质条件下，为了在钻井过程中最优地发现所有预定目标，俄油开发了一种s形轨迹的钻井设计。裸眼井的地球物理研究结果证实了生产层的含油饱和度。 俄油目前正在进行套管测试的准备工作。据初步估计，这个新发现油田的石油储量200万吨，这个储量数将被纳入俄罗斯今年国家资产负债表中。 在这个项目的进一步开发过程中，俄油将对新油田投产的时间作出决定。目前在这个许可证区块中钻探的第一口勘探井证实了俄油地质学家早些时候对整个区块作出的1100万吨油当量资源潜力的预测。 李峻 编译自 俄罗斯油气网 原文如下： Rosneft discovers new field offshore Sakhalin Neftegaz.RU. As part of its exploration campaign, Rosneft has successfully completed the drilling of the 1st prospecting and appraisal well at the Vostochno-Pribrezhny license block on the shelf of Sakhalin Island, resulting in the discovery of a new oil field. The well was drilled by Rosneft’s own drilling contractor RN-Burenie in accordance with the planned dates and all safety and environmental protection standards. As a result of drilling, the measured depth was 3,047 m; the vertical deviation was 1,450 m. A well design that provided for drilling 2 holes with S-shaped paths was developed for optimal discovery of all intended targets in the course of drilling in difficult geological conditions. A set of geophysical studies in the open hole confirmed the oil saturation of productive formations. Preparations are now underway to test the well in casing. According to preliminary estimates, the reserves are up to 2 million tonnes of oil, which will be included in the State balance sheet in 2019. In the course of further development of the project, decisions will be made on the timing of the commissioning of the new field. The 1st well drilled in the licensed area at the moment confirms the forecast made earlier by the company’s geologists for the resource potential of the entire area of 11 million tonnes of oil equivalent. |
