中国石化新闻网讯 据俄罗斯油气网莫斯科报道，俄罗斯第2大天然气公司诺瓦泰克宣布，该公司的合资企业雅吉欧(Yargeo)日前在雅鲁杰伊斯科耶大油田成功完钻了第68口针对侏罗系地层的创纪录油流量的高产油井。作为建井设计的一部分，此井水平段长度达到了1068米。 初始每日井石油流量为1010吨，这是雅鲁杰伊斯科耶大油田自2015年投产以来的最佳井流量。由于该井独特的设计，在没有水力压裂的情况下实现了创纪录的井流量，这也是这个油田维持石油产量计划的一部分。 2015年6月，诺瓦泰克在雅鲁杰伊斯科耶大油田启动了商业化生产。雅鲁杰伊斯科耶大油田由雅吉欧开发，雅吉欧是诺瓦泰克(51%)和奈夫特石油有限公司(49%)组建的合资企业。 雅鲁杰伊斯科耶油田是诺瓦泰克投资组合中的最大原油资产，其特点是独特的地质，结合先进的钻井和完井技术的应用使诺瓦泰克能够在这个油田平均每天每口井达到超过350吨的生产流量。雅鲁杰伊斯科耶油田的平均井流量是西伯利亚西部油田中产量最高的油田之一。 这个油田的生产复杂性具有高石蜡含量(高达17%)和高凝点(约+15°C)的特点。诺瓦泰克的专家与俄罗斯的设计单位和研究机构一起开发了技术解决方案，使优化油田的原油产量成为了可能，并在最短的时间内达到了设计能力。 李峻 编译自 俄罗斯油气网 原文如下： Record oil flow rate well completed at the Yarudeyskoye field NOVATEK announced today, that Yargeo, the company´s joint venture, successfully completed well number 68 targeting the Jurassic layers at the Yarudeyskoye field, utilizing a horizontal length of 1,068 meters as part of the well construction design. Initial daily well flow rate amounted to 1,010 tons, representing the field’s best well flow rates since commissioning of the field in 2015. The flow rate was achieved without hydro-fracturing due to the well’s unique design, and is part of a program to maintain the field’s oil production. In June 2015 NOVATEK launched the start of commercial production at the major Yarudeyskoye oil field. The field is developed by Yargeo, a joint venture between NOVATEK (51%) and Nefte Petroleum Limited (49%). The Yarudeyskoye field is the largest crude oil asset in the company’s portfolio, and is characterized by unique geology, which combined with the application of state-of-the-art drilling and completion technologies allowed us to achieve the average production flow rate of more than 350 tons per day per well. The field’s average flow rate is one of the highest production output amongst fields producing in Western Siberia. The field’s production complexity is characterized with high paraffin content (up to 17%) and a high pour point (about +15 °C). NOVATEK's specialists, together with Russian design organizations and research institutes, developed technological solutions that made it possible to optimize the field’s crude oil output and reach its design capacity in minimal time.
