柴达木英雄岭页岩油作为全球独具特色的"高原山地式"陆相页岩油藏，受喜马拉雅构造运动多期强改造 和沉积环境高频变化作用的共同影响，地下地质与地上地表条件"双复杂"，呈现出咸化湖盆巨厚混源沉 积、低有机质丰度烃源岩高效生烃和构造复杂等特点，与国内外构造相对稳定的海相和陆相页岩油藏在 地质背景和富集条件方面具有明显差异。同时，英雄岭地区地处偏远、社会依托弱，加之高寒缺氧、干 旱缺水，导致页岩油勘探开发难度极大。 "近年来，研究团队针对英雄岭页岩油有多少、在哪里、哪里好、如何采等关键问题开展系统攻关，实 现勘探战略突破，形成配套技术体系。"青海油田勘探开发研究院英雄岭页岩油勘探开发项目负责人伍 坤宇表示，目前已完成3个开发先导试验平台的部署实施，为今后规模增储和效益上产提供科学指导。 (完) 深居中国西北干旱内陆、青藏高原北部的柴达木盆地平均海拔超3000米，是全球最具代表性的高原含油 气盆地。 历经多年开发，柴达木盆地油田探明储量动用程度高、产量递减压力大，亟需拓展新领域。为保障油田 持续增储上产，2021年起，中国石油天然气股份有限公司青海油田分公司研究团队梳理研究柴达木盆地 非常规油气地质特征、勘探开发关键技术 ...

中新网松原5月13日电 (郭佳高东旭)在位于吉林省松原市的中国石油吉林油田公司黑46区块，从长岭天 然气净化站分离出的二氧化碳经过12.6公里的运输管道，源源不断地注入地下。 4月28日，吉林松原，吉林油田一平台正利用CCUS技术开采石油。 郭佳摄 "把注入地下的二氧化碳作为开采石油的介质，开采效率比传统的水介质要高25%，这样每年可以多开 采20多万吨石油。"中国石油吉林油田二氧化碳开发公司(一体化中心)主任张德平13日受访时说。 中国石油吉林油田公司最新数据显示，今年前4个月，埋存二氧化碳14.8万吨，至此埋存二氧化碳总量 已接近400万吨，相当于植树3400万棵、200余万辆经济型轿车停开一年，埋存二氧化碳总量稳居中国第 一。 2005年，吉林油田在科尔沁草原深处发现了中国陆上第一个火山岩气田——长岭气田。该气田虽然天然 气蕴藏丰富，但二氧化碳含量高达20%以上，若清洁开采必先解决伴生二氧化碳气体的去向问题。 为解决这一难题，吉林油田将大情字井油田黑59、黑79、黑46区块列为先期"试验田"，在国内率先走通 了二氧化碳捕集输送、集输处理、循环注入全流程，累计申报国家专利技术30多项。 凭借系列自主技术， ...
