Conditions of Petroleum Geology of the Qiangtang Basin of the Qinghai-Tibet Plateau

Acta Geologica Sinica(English Edition) 2000年第3期74卷 661-665页

The Qinghai-Tibet Plateau located in the Tethyan tectonic domain is the best developed region of Mesozoic and Cenozoic marine sediments in China. The Qiangtang basin is the biggest and relatively stable area of the plateau. Triassic and Jurassic hydrocarbon source rocks are extensively distributed in the basin. There exist good dolomite and organic reef reservoirs and mudstone and evaporite cap rocks, as well as well-developed structural traps in the basin; in addition destroyed petroleum traps have been discovered. Therefore, the conditions of petroleum geology in the Qiangtang basin are excellent

Leading-edge technologies in hydropower development in China

Global Energy Interconnection 2019年第3期2卷 244-253页

作者： Zeyan Yang Chao Liu Mingxin Wu China Renewable Energy Engineering Institute No. 2 North Alley Liupukang Community Xicheng District Beijing China 100120

After the implementation of the Reform and Opening-up Policy for a period of 40 years, the exploitation of Chin a's hydropower resources developed significa ntly. Through vast amounts of scie ntific and tech no logical research and construction practices, China has accumulated abundant engineering experience with respect to the construction technologies required for 300-meter-high concrete arch dams, 200-meter-high roller-compacted concrete gravity dams, 200-meter-high concrete face rockfill dams, 250?meter?high earth core rockfill dams, large-flow discharge and energy dissipation, huge underground cavern group constructions, complicated foundation treatments for high earth and rockfill dams and high and steep slope reinforceme nts. These series of tech no logies have now reached an inter national leadi ng level. In the near future, these technical improvements will likely have broader application prospects and make greater contributions toward hydropower development both in China and across the world.

The Genetic Mechanism and Model of Deep-Basin Gas Accumulation and Methods for Predicting the Favorable Areas

As a kind of abnormal natural gas formed with special mechanism, the deep-basin gas, accumulated in the lower parts of a basin or syncline and trapped by a tight reservoir, has such characteristics as gas-water inversion, abnormal pressure, continuous distribution and tremendous reserves. Being a geological product of the evolution of petroliferous basins by the end of the middle-late stages, the formation of a deep-basin gas accumulation must meet four conditions, i.e., continuous and sufficient gas supply, tight reservoirs in continuous distribution, good sealing caps and stable structures. The areas, where the expansion force of natural gas is smaller than the sum of the capillary force and the hydrostatic pressure within tight reservoirs, are favorable for forming deep-basin gas pools. The range delineated by the above two forces corresponds to that of the deep-basin gas trap. Within the scope of the deep-basin gas trap, the balance relationship between the amounts of ingoing and overflowing gases determines the gas-bearing area of the deep-basin gas pool. The gas volume in regions with high porosity and high permeability is worth exploring under current technical conditions and it is equivalent to the practical resources (about 10%-20% of the deep-basin gas). Based on studies of deep-basin gas formation conditions, the theory of force balance and the equation of material balance, the favorable areas and gas-containing ranges, as well as possible gas-rich regions are preliminarily predicted in the deep-basin gas pools in the Upper Paleozoic He-8 segment of the Ordos basin.
