中国石油“十一五”以来油气勘探成果、地质新认识与技术进展

"十一五"以来,中国石油突出资源战略,大力实施油气储量增长高峰期工程,在鄂尔多斯、塔里木、四川、准噶尔、松辽、柴达木、渤海湾等大型含油气盆地取得了一系列重大成果,形成了中国石油历史上持续时间最长的储量增长高峰期。同时,随着油气勘探的持续突破,海相碳酸盐岩、前陆冲断带、大面积砂岩、火山岩、潜山及其内幕油气藏、致密油气、页岩气等油气地质认识取得重要新进展,进一步丰富和发展了中国石油地质理论。勘探工程技术攻关有效地促进了工程技术的快速发展,物探采集、处理、解释技术、复杂地区和深井的钻井提速,以及复杂储层和油气藏测井评价技术、水平井钻完井+体积压裂技术等发展迅速,形成了一系列针对不同勘探领域的配套技术。未来油气勘探对象日趋复杂,勘探难度加大,但随着地质认识的深化和勘探技术的进步,油气勘探仍具有良好的发展前景。

PetroChina＇s Oil and Gas Exploration Results,New Geological Theories and Technological Achievements Since 11th Five-Year Plan Period

PetroChina has highlighted its resources strategy and spared no efforts to increase its oil and gas reserves since the 1 lth Five- Year Plan Period. The company has achieved a series of important results in large-scale hydrocarbon basins like Ordos Basin, Tarim Basin, Sichuan Basin, Jnnggar Basin, Songliao Basin, Qaidam Basin and Bohai Bay Basin, leading to a longest peak for reserves growth in PetroChina＇s history. Meanwhile, with the breakthroughs made continually in oil and gas exploration, PetroChina has also made an important progress in geological theories in the areas of marine carbonate rock, frontal thrust belt, large-area sandstone, volcanic rock, buried hill and its inner curtain oil and gas reservoirs, tight oil and gas, and shale gas, further enriching and developing China＇s petroleum geological theories. The study of exploration engineering technology has effectively promoted rapid development in this area. Development of geophysical acquisition, processing and interpretation technology, higher drilling rate for complicated zones and deep wells, logging appraisal technology for complex reservoir, and horizontal well drilling technology including volumetric fracturing technology has shaped a series of technologies for exploration of different areas. The oil and gas exploration targets will be increasingly complicated and more difficult in the future. However, the development prospect for oil and gas exploration remains promising thanks to the progress in geological theories and exploration technologies.
