This article examines Russian energy policies toward China over the past decade as reluctant engagement changed into a priority energy partnership. From 2008 to 2016 Russian and Chinese companies signed several major oil and gas agreements, a period in which Moscow reassessed China as a future energy consumer and lifted bilateral cooperation to a new level. The article utilizes the strategic partnership concept as an analytical framework and finds traditional realist concepts and hedging inadequate for this particular case. The study illuminates Russian geopolitical considerations and acceptance of vulnerability, which combined make long-term Russian energy policies more China dependent. Officially, Russia seeks diversification among Asian energy buyers, but its focus has increasingly been on China. Western sanctions imposed in 2014 for Russia’s role in Ukraine accelerated this trend. Moscow’s energy policies toward Beijing with its pipelines and long-term agreements are permanent arrangements that resemble strategic partnership policies. China is eager to increase energy relations with Russian companies, but Beijing also ensures that it does not become too dependent on one supplier. Russian concern over its increased dependence on China in the East is deemed secondary to expanding Russia’s customer base beyond the still-dominant European market. 相似文献

Interpretation of high‐resolution two‐dimensional (2D) and three‐dimensional (3D) seismic data collected in the Qiongdongnan Basin, South China Sea reveals the presence of polygonal faults, pockmarks, gas chimneys and slope failure in strata of Pliocene and younger age. The gas chimneys are characterized by low‐amplitude reflections, acoustic turbidity and low P‐wave velocity indicating fluid expulsion pathways. Coherence time slices show that the polygonal faults are restricted to sediments with moderate‐amplitude, continuous reflections. Gas hydrates are identified in seismic data by the presence of bottom simulating reflectors (BSRs), which have high amplitude, reverse polarity and are subparallel to seafloor. Mud diapirism and mounded structures have variable geometry and a great diversity regarding the origin of the fluid and the parent beds. The gas chimneys, mud diapirism, polygonal faults and a seismic facies‐change facilitate the upward migration of thermogenic fluids from underlying sediments. Fluids can be temporarily trapped below the gas hydrate stability zone, but fluid advection may cause gas hydrate dissociation and affect the thickness of gas hydrate zone. The fluid accumulation leads to the generation of excess pore fluids that release along faults, forming pockmarks and mud volcanoes on the seafloor. These features are indicators of fluid flow in a tectonically‐quiescent sequence, Qiongdongnan Basin. Geofluids (2010) 10 , 351–368 相似文献

The paper surveys the Russian aluminum industry during the turbulent transition years of the 1990s, and updates developments to the current period. The focus is on primary aluminum production, with emphasis on the key topics of ownership and governance, output and performance, costs of production (dominated by energy and transportation), investments, technology, and alumina and bauxite inputs. Considerable attention is devoted to elucidating the corporate strategies of the two dominant Russian aluminum companies emerging by the end of the period—Rusal and SUAL.

The concentrations of H2, O2, CO2, and concentrations and isotopic composition of the noble gases (including 222Rn), N2, CH4, and higher hydrocarbons dissolved in 4000 m deep‐seated fluids from a 12‐month fluid production test in the KTB pilot hole were analyzed. This determination of the gas geochemistry during the test in combination with the knowledge of the hydraulic data provides relevant information about the fluid hydraulics of the deep system. All gas concentrations and isotopic signatures, except for 222Rn, showed constancy during the course of the test. This, in combination with large fluid flow rates at a moderate water table drawdown, imply an almost infinite fluid reservoir in 4000 m depth. From the change in 222Rn‐activity as a function of pump rate, the contribution of smaller and wider pores to the overall fluid flow in an aquifer can be deduced. This 222Rn‐activity monitoring proved therefore to be a valuable instrument for the qualitative observation of the scavenging of pore and fracture surfaces, a hydraulic feature invisible to standard hydraulic testing tools. The observance of this scavenging effect is due to (i) the continuous on‐line geochemical monitoring, (ii) the durability of the test, (iii) a change in pump rate during the course of the test, and (iv) due to the short half‐life of 222Rn. The fluids have a 5.9% mantle He component, and a δ21Ne excess of 14%, and a noble gas model age of about (5.5–6.2) ± 2.0 Myr. The mean N2/Ar‐ratio of 516 and δ15N‐data of about +1.5‰ indicates sedimentary or metamorphic origin of N2. The hydrocarbons, amounting to 33 vol.% in the gas phase, are derived from thermal decomposition of marine organic matter of low maturity. But a key question, the identification of the potential source region of the fluids and the migration pathway, is still unidentified. 相似文献

Seismic evidence for fluid migration pathways from an overpressured system in the South China Sea 总被引:1,自引:0,他引:1
Overpressured systems and intense, anomalously hot fluid expulsion in the Yinggehai Basin of the South China Sea offer an opportunity to understand the history of fluid flow and the process of hydrocarbon accumulation in overpressured environments. Fluid migration pathways from overpressured compartments in the basin are largely controlled by the distribution of faults and fractures. Episodic opening of these faults are related to the dynamics of an overpressured system and tectonic movements during basin evolution. At the crests of diapiric structures, fluid expulsion is seismically imaged as chimney‐ or plume‐like features, low to middle seismic amplitudes, and intermittently chaotic and blank reflecting seismic facies. These fluid pathways are controlled by vertical faults, which commonly penetrate overpressured and overlying normally pressured zones. Fluid expulsion is also observed near the main faults, such as the No. 1 Fault at the north‐eastern margin of the basin. Investigation by sidescan sonar on onshore and offshore Hainan Island indicates that there are more than 100 gas seepages adjacent to the No. 1 Fault. Migration pathways in the diapiric structures are controlled by three types of fault and fracture. Penetrative faults formed by dextral strike‐slip movement of the Red River faults commonly occur in the centre of the diapirs, and may have been a triggering factor for the diapirism, and controlled their distribution. Hydrofractures occur in certain mud‐rich layers and may have been generated by hydraulic fracturing. Radial normal faults occur at the top of diapirs and were formed by the intrusive process. These fluid migration pathways played an important role in regional hydrocarbon accumulation. 相似文献

In 2009, the remnants of Her Majesty's Queensland Ship Mosquito, a 2nd‐class torpedo‐boat built in 1883, were relocated. Purchased by the colonial government of Australia in response to heightened tensions between Great Britain and Imperial Russia, Mosquito was assigned to Queensland's capital, Brisbane, where it had a largely uneventful career. Following removal from active duty it was stripped and abandoned on the foreshore of a tributary of the Brisbane River. This paper discusses Mosquito's historical background, and chronicles the rediscovery of the vessel, and the archaeological investigation and identification of its remains. © 2010 The Author 相似文献

The article analyses the perception of the mid-to-late nineteenth-century Russian liberals of the West European states and their foreign policy of the time towards Russia. The article discloses the main features and differences in assessing the West and Russia as its part. It allows to reveal such features in Russian liberalism as common provisions and values typical of world liberal theory and a number of special features which resulted in developing different schools of liberal movement in Russia. The article underlines that the range of liberal ideas varied from selective borrowing of some elements of the western political system to their complete adaptation in Russia. The article focuses on the opinion of a number of national-oriented Russian liberals of the time who put forward a priority task to modernize the country, to implement liberal reforms, but not to strengthen its foreign policy power which, according to them, prevents improving well-being of the people and social stabilization.
The study allows to define a main vector of the ideological pursuit of the Russian liberals, the part of whom tried to enroot the liberal ideas in the backward peasant country. 相似文献

Nationalism and revolution have generally been held to go together. Many nation‐states have had their origins in revolution, from the Americans in the 18th century to a host of Third World nation‐states in the 20th century. Generally, both modern revolutions and modern nationalism have the same origins, in 18th century Enlightenment thought. But this paper argues that, despite this common origin, the principles of revolution and nationalism are divergent, and can set one against the other. Revolutions emphasise freedom and equality; nationalism emphasises integration and unification. These principles can clash, though not inevitably and not always. The paper examines the 1789 French Revolution, the 1848 revolutions and the 1917 Russian revolution. It shows that in the first two cases, revolutionary aspirations came up against and were eventually displaced by nationalist aims. In the case of 1917, revolution paradoxically, and unintentionally, institutionalised nationalism. These examples show that, though linked at some high level of modern thought, revolution and nationalism express different and at times divergent strands of modernity. 相似文献

This contribution focuses on the right of nations to self-determination after the Russian invasion of Ukraine. It suggests that sovereignty and territorial integrity are not as secure as once thought. A number of articles and statements issued by Vladimir Putin are analysed to identify nationalist themes which he uses to reject Ukraine's right to exist outside the Russian state. Key themes include a primordial account of national origins, the conflation of state and nation, and a refusal to recognise a right to self-determination of territories that had once been part of Russia. Putin's nationalism draws on imperial nationalism, state nationalism, revanchism and majoritarianism to underwrite his claims. Such views are widespread among established states, contributing to the instability of the contemporary world. It is argued that a reconfiguration of the relationship between state and nation is long overdue, as is the inflexible nature of territorial integrity. 相似文献
