油气资源是油气工业的基础,极大地关系到国民经济的发展。近年来,我国的石油勘探形势发生了明显的变化:年新增石油探明储量下降,石油年产量连续3年(2016—2018年)下降,2018年石油对外依存度高达73%。因此,亟需对油气资源状况开展全面客观的评价,夯实国内常规与非常规油气资源的基础,明确剩余油气资源的重点勘探领域与有利勘探方向。中石油以近十几年来取得的油气勘探成果、地质认识成果与资料积累成果为基础,攻关形成常规与非常规油气资源评价方法技术体系,针对中石油矿权区及全国主要含油气盆地系统开展了第四次油气资源评价。评价结果显示:我国常规石油地质资源量约为1080×10~8 t;非常规石油地质资源量为672.08×10~8 t,其中包括致密油125.80×10~8 t,油页岩油533.73×10~8t,油砂油12.55×10~8 t。陆上常规剩余石油资源主要分布在岩性-地层(碎屑岩)、复杂构造2大重点领域;海域石油资源主要集中在海域构造、生物礁和深水岩性3个领域。在剩余石油资源分析的基础上,优选出常规石油现实有利目标区带20个,致密油有利目标区带12个,油页岩油露天挖掘目标6个、原位改质目标4个,油砂油有利目标5个。 相似文献

正中国陆上39%的剩余石油资源和57%的剩余天然气资源分布在深层。深层石油地质资源量约153.81亿吨,天然气约16.52万亿立方米。但深层油气资源的探明率较低,分别为12%和6.3%,远低于石油总体探明率35.5%和天然气探明率17.9%的水平。以上数据表明我国深层油气资源相当丰富,勘探潜力巨大。利用三维地震勘探技术,在美国西 相似文献

伊拉克油气资源丰富，探明石油储量超过1125亿桶，天然气储量110万亿立方英尺。中国2001年石油进口量的55％来自中东，中东局势紧张，会直接影响中国石油的稳定供应。通过详细分析伊拉克石油资源状况，结合中国实际情况，探讨其对中国能源安全战略的影响，认为中国在摸清家底，加强国内油气地质勘查工作，包括全国油气资源战略选区工作，提高石油地质储量，增加国内生产能力的同时，应积极拓展中亚—俄罗斯、中东—北非和南美石油市场，实现原油进口地区的多元化，以降低对中东石油进口的依赖程度。 相似文献

The Silk Road Economic Belt and the 21st-Century Maritime Silk Road Initiative, abbreviated as the Belt and Road Initiative, is a primary development strategy of China’s future international cooperation. Especially, the energy resource cooperation, including oil and gas resources cooperation, is an important part of this initiative. The Belt and Road has undergone complicated geological evolution, and contains abundant mineral resources such as oil, gas, coal, uranium, iron, copper, gold and manganese ore resources. Among these, Africa holds 7.8% of the world’s total proven oil reserves. The oil and gas resources in Africa are relatively concentrated, with an overall low exploration degree and small consumption demand. Nigeria and Libya contain the most abundant oil resources in Africa, accounting for 2.2% and 2.9% of the world’s total reserves, respectively. Nigeria and Algeria hold the richest natural gas resources in Africa, occupying 2.8% and 2.4% of the world’s total reserves, respectively. Africa’s oil and gas resources are mainly concentrated in Egypt, Sultan and Western Sahara regions in the northern Africa, and the Gulf of Guinea, Niger River and Congo River area in the western Africa. The Russia–Central Asia area holds rich petroleum resources in Russia, Kazakhstan, Turkmenistan and Uzbekistan. The potential oil and gas areas include the West Siberia Basin, East Siberia Basin and sea continental shelf in Russia, the northern and central Caspian Basin in Kazakhstan, the right bank of the Amu-Darya Basin, the East Karakum uplift and the South Caspian Basin in Turkmenistan, and the Amu–Daria Basin, Fergana Basin, Afghan–Tajik Basin and North Ustyurt Basin in Uzbekistan. The Middle East oil and gas resources are mainly distributed in the Zagros foreland basin and Arabian continental margin basin, and the main oil-producing countries include Saudi Arabia, Iran and Iraq. The Asia Pacific region is a new oil and gas consumption center, with rapid growth of oil and gas demand. In 2012, this region consumed about 33.6% of the world’s total oil consumption and 18.9% of the world’s total natural gas consumption, which has been ranked the world’s largest oil and gas consumption center. The oil and gas resources are concentrated in China, Indosinian, Malaysia, Australia and India. The abundant European proven crude oil reserves are in Norway, Britain and Denmark and also rich natural gas resources in Norway, Holland and Britain. Norway and Britain contain about 77.5% of European proven oil reserves, which accounts for only 0.9% of the world’s proven reserves. The Europe includes main petroliferous basins of the Voring Basin, Anglo–Dutch Basin, Northwest German Basin, Northeast German–Polish Basin and Carpathian Basin. According to the analysis of source rocks, reservoir rocks, cap rocks and traps for the main petroliferous basins, the potential oil and gas prospecting targets in the Belt and Road are mainly the Zagros Basin and Arabic Platform in the Middle East, the East Barents Sea Basin and the East Siberia Basin in Russia–Central Asia, the Niger Delta Basin, East African rift system and the Australia Northwest Shelf. With the development of oil and gas theory and exploration technology, unconventional petroleum resources will play an increasingly important role in oil and gas industry. 相似文献

With a population of 1.3 billion, China is a large agricultural country. However, China is short of potash resources as the external dependence is more than 50% for many years. With the limited possibility for increasing potash reserves from surface salt lakes, and the challenge of finding potash deposit from marine strata has not been yet overcome, the oil (gas) field brine resources has become the preferred source for the urgent needs of potash. In recent years, a lot of exploration and research work on the oil (gas) field brine has been done under the guide of “oil and potash co-exploration” policy and delightful achievements have been obtained. The research achievements at Qaidam Basin, Sichuan Basin, Jianghan Basin and Tarim Basin were summarized in the present paper. All of the above basins are the most important areas with great prospects of oil (gas) field brine. This paper mainly focused on three aspects, the brine characteristics, the brine geochemistry and resource assessment. After the summary, the characteristics of oil (gas) field brine and the progress in study of that were gotten in different basins. It was suggested that the research work of (gas) field brine at Qaidam Basin should be emphasized. It was concluded that the evaluation work of oil (gas) field brine resources is insufficient at the four basins, and it is urgent to establish oil (gas) field brine resources evaluation criteria and methods. 相似文献

世界油页岩资源开发利用现状与发展前景 总被引：5，自引：0，他引：5
由于世界原油价格的高涨和常规油气资源的短缺,非常规油气资源中的油页岩以资源丰富、经济性和开发利用的可行性成为21 世纪重要的石油补充和替代能源。世界油页岩资源探明储量折算成页岩油约70%分布在美国,其次集中分布在中国、俄罗斯、巴西、加拿大、约旦、澳大利亚和爱沙尼亚等; 中国油页岩资源约85%以上分布在吉林、辽宁和广东省。随着各国重新或开始重视油页岩的开发与利用,油页岩的储量、页岩油的产量和油页岩开发利用的经济价值都呈增长趋势,相应的政策支持力度也在加大。 相似文献

The world’s present demand for oil and gas is still in a rapid growth period, and traditional oil and gas resources account for more than 60% of the global oil and gas supply. The Americas is the world’s second largest production and consumption center of liquid fuel, and is also the world’s largest natural gas producer. In 2016, the Americas had 85.3 billion tons of proven oil reserves and 18.7 trillion m3 of proven natural gas reserves, which account for 35.4% and 10.0% of world’s total reserves, respectively. It produced 1267.1 Mt of oil and 1125.4 billion m3 of natural gas, which account for 28.9% and 31.7% of the world’s total production, respectively. The crude oil and natural gas reserves are mainly distributed in the U.S., Canada and Venezuela. The U.S. is the earliest and most successful country in shale gas exploration and development, and its shale gas is concentrated in the southern, central and eastern U.S., including the Marcellcus shale, Barnett shale, EagleFord shale, Bakken shale, Fayettevis shale, Haynsvill shale, Woodford shale and Monterey/Santos shale. The potential oil and gas resources in the Americas are mainly concentrated in the anticline and stratigraphic traps in the Middle-Upper Jurassic slope deposition of the North Slope Basin, the Paleozoic Madsion group dolomite and limestone in the Williston Basin, dominant stratigraphic traps and few structural traps in the Western Canada Sedimentary Basin, the Eocene structural-stratigraphic hydrocarbon combination, structural-unconformity traps and structural hydrocarbon combination, and the Upper Miocene stratigraphic-structural hydrocarbon combination in the Maracaibo Basin of Venezuela, the stratigraphic-structural traps and fault horst, tilting faulted blocks and anticlines related to subsalt structure and basement activity in the Campos Basin, the subsalt central low-uplift belt and supra-salt central low-uplift belt in the Santos Basin of Brazil, and the structural-stratigraphic traps in the Neuquen Basin of Argentina. In addition, the breakthrough of seismic subsalt imaging technology makes the subsalt deepwater sea area of eastern Barzil an important oil and gas potential area. 相似文献

钛矿是我国对外依存度较高的矿种之一,对我国战略性新兴产业的发展起着重要的支撑作用,对全球钛矿行业的发展现状进行分析与研究,能够为我国钛矿资源安全提供重要研究依据.本文对全球钛资源的储量及分布状况、钛资源的生产和消费情况进行了分析.分析结果显示,我国是钛资源大国,钛储量位居世界第一;但多为共伴生矿,品位不高.钛精矿进口量呈逐年上升趋势,对外依存度超过了60％.受当今国际政治经济环境的影响,钛矿资源的国际贸易形势必然会受到影响.同时随着我国战略性新兴产业的发展,钛的消费需求将不断增加,因此,加大我国钛资源的勘查和资源储备,加快我国钛行业的产业升级转型以及保障钛矿的资源供给安全是未来整个行业的重要议题. 相似文献

页岩气是化石能源中相对清洁高效的一种天然气.美国的页岩气革命可以算是本世纪最具影响力的能源革命,使其实现了梦寐以求的“能源独立”.从美国的经验来看,页岩气革命可以认为是开放市场和解放思想的成果,是完全竞争市场模式理论在页岩气资源开发中的成功实践.中国页岩气技术可采储量为世界第一,但由于中国页岩气管理体制等原因的制约,目前中国只在个别区块取得了勘探突破,离页岩气的大规模商业开采还有比较长的路.通过对页岩气资源管理体制深入分析,总结和讨论传统油气管理体制的不足以及美国页岩气开发给我国页岩气资源开发的启示,运用西方经济学经典的完全竞争市场模式理论对页岩气资源管理体制改革及相关政策提出适当建议. 相似文献
