Weiyuan gas field, located in the Sichuan basin of south China, is a large marine gas field with the oldest reservoir (the Sinian sequences) in south China. The hydrocarbon origin of the gas field has long been debated by petroleum geologists. Recently, it was recognized that a paleo-oil pool maybe the significant contributor to the gas field. Consequently, when the paleo-oil pool had been crac...

Tazhong Oil Field located in the center of Tarim Basin is one of the greatest discoveries during the petroleum exploration in Tarim Basin. The course of many years for hydrocarbon exploration and development has proved that there existed a much larger ancient reservoir than present-day reservoir and residual oil section below present WOC is of obvious characteristics of water displacement. Stud...

The heterogeneity of deep carbonate reservoirs is strong, it significant for exploration and development to clarify the key stages oil gas accumulation. Taking Ordovician in Gucheng area Tarim Basin as an example, this paper systematically investigated stage model hydrocarbon accumulation using data cores, thin sections, cathode luminescence tests, laser ablation U-Pb isotope geochronometry, bi...

Original scientific paper Studies on the evolution of paleo-channels in coastal areas are important for submarine engineering construction and to reveal changes in the global paleoenvironment. Thus, to explore the characteristics of paleo-channels during the late Last Glaciation in the western South Yellow Sea, digital terrain analysis method and ArcGis river extraction function were employed, ...

Suicide in China accounts for about a quarter of all suicides worldwide. In contrast to western populations, in China more women than men kill themselves. It is a gloomy picture, but there are signs that the situation may be improving. Cui Weiyuan reports.

Since the Land Administration Bureau was established in 1986, China has carried out the national land-use planning twice, of which the first was focused on "serving for social and economic development", and the second converted to “protecting arable land". At present a new round of land-use planning is ongoing (2005-2020), but the aims and requirements are even more and higher(Zheng Weiyuan,200...

Bull World Health Organ 2010;88:885–886 | doi:10.2471/BLT.10.031210 Infertility is a public health problem that affects all societies, not least traditional ones such as the Maasai of East Africa. In this Bulletin interview, Weiyuan Cui talks to Dr Yadira Roggeveen, a medical officer at Endulen Hospital in the Ngorongoro Conservation Area in the United Republic of Tanzania. Maasai couples seek ...

To reveal the film formation mechanism of oil-in-water (O/W) emulsion, nanofilms of aqueous paraffin oil emulsion stabilized with the nonionic Tween 80 and Span 80 surfactants were measured in confinement between two solid surfaces, by the use of relative optical interference intensity (ROII) approach. In contrast to single-phase oil lubricant, the film formation of oil-in-water emulsions norma...
