石油圈中国石化新闻网讯 据路透社8月14日东京报道，日本国内的上游公司时下正在加紧寻找致密油来弥补国内不断下降的产量并可能寻求利用所获得的经验参与海外类似的项目。 自从在位于日本西北部秋田省其陆上油田的Onnagawa致密地层中钻取日本第一口水平勘探井以来，日本石油勘探公司（Japex）打算在2020年3月底之前的3年时间里寻找更多的远景构造。 Japex的日本Onnagawa页岩油项目研究小组的地质和技术顾问Satoru Yokoi在接受标普全球普氏能源资讯记者采访时说：“尽管我们迄今还不能承诺，但我们将在实施当前中期商业计划期间监测油价。” 日本页岩油先驱者之一的Yokoi说，在今年早些时候完成了一次涉及从水平井进行多阶段水力压裂试验的Japex在Onnagawa地层中成功地进行了水力压裂作业。 在从2014年起在Fukumezawa油田实施的钻井和压裂作业最初未能生产自然流以后，Japex暂停了生产测试来寻找可能的原因以及考虑改进计划。 李峻 编译自 普氏能源资讯 原文如下： Japan pursuing tight oil at home, may seek it abroad too Japanese upstream companies are looking to tight oil to supplement dwindling domestic output and may seek to use the experience gained to become involved in similar projects abroad.
Japan Petroleum Exploration intends to seek out further prospects by the end of March 2020 over three years since the drilling of Japan’s first horizontal exploration well in the Onnagawa tight formation at its onshore oil field in northwestern Akita province.
“While we cannot commit ourselves yet, we will look into the opportunities while monitoring oil prices during the current medium-term business plan,” Satoru Yokoi, geologist and technical fellow of Japex’s Japan-Onnagawa shale oil project team said in an interview with S&P Global Platts.
Japex, which earlier this year concluded a pilot test involving multi-stage fracturing from a horizontal well, successfully fractured mostly as intended in the Onnagawa formation, Yokoi, one of Japan’s shale pioneers, said.
After drilling and fracturing from 2014 at the Fukumezawa oil field – one of the Sarukawa oil fields at Oga city in Akita, about 600 km (372 miles) north of Tokyo – initially failed to produce natural flows, Japex paused output tests to look into probable causes and consider plans for improvement.
