Abstract: The effects of TFC on cytokines levels, total antioxidant activity, antinociceptive effects in vivo, LD50 and tactile hyperalgesia were analyzed respectively.TFC treatment decreased the levels of cytokines and total antioxidant status (TAOS) and inhibited the acetic acid-induced abdominal constrictions in mice. In addition, TFC reduced CFA-induced tactile hyperalgesia in a dose-dependent manner and the LD50 of TFC was determined to be 400?mg/kg. However, TFC did not significantly inhibit the reaction time to thermal stimuli in the hot-plate test.TFC showed anti-inflammatory, antioxidant, peripheral antinociceptive and antihyperalgesic activity in various models of inflammatory pain. The data suggest that TFC may be a viable treatment option for inflammatory pain.

Abstract: 摘要: 摘要:祁连山地区天然气水合物分布较为复杂,急需对该区天然气水合物成藏控制因素与成藏模式进行深入研究。本次重点对青海木里三露天天然气水合物系 列钻井揭示的地质资料及各种样品分析测试结果进行综合分析,结果显示:该区天然气水合物气源以油型热解成因气为主,少部分在浅部混有部分微生物成因气及煤成气,这些油型热解成因 气源主要由下部或更深部上三叠统或二叠系提供;当气源岩生成烃类气体后运移至浅部直接或间接由断裂连同泥岩、油页岩等封堵形成浅部气体聚集;浅部气体聚集体局部加入微生物成因气 或煤成气,经过不晚于中更新世早期形成的岛状永久冻土作用,在天然气水合物稳定带内与水结合形成天然气水合物,当它们处在天然气水合物稳定带之外便在更浅部以异常高压气层或游离( 吸附)气存在。由于气源类型与供应条件、运移与聚集条件、天然气水合物稳定带范围的不同,它们之间的匹配关系在不同位置具有很大的差异性,从而影响该区天然气水合物在横向平面上和 纵向剖面上分布与产出的不均性。
Abstract: The distribution of gas hydrate is very complex in Qilian area, therefore it is urgent to study the controlling factors and the formation pattern of gas hydrate in this area. The geological data and analytical results of various samples collected from the series of gas hydrate drilling holes are emphatically studied in Sanlutian. Results show that gas source for gas hydrate in the study area is mainly composed of oil-typed thermo-genic gases and this kind of gas source is partially mixed with some biogenic gas or coal gas in the shallow. And the oil-typed thermo-genic gases are mainly derived from lower or deeper Upper Triassic or Permian. When gas source migrated upward and arrived at the shallow formation, gases were directly or indirectly blocked by fracture and other seals such as mudstone, oil shale, thus causing shallow gas accumulation. Shallow gas was locally added by microbial gas or coal gas. They together with water were formed into gas hydrate in gas hydrate stability zone after these gases were encountered into frozen formation which happened no later than early Middle Pleistocene. Parts of them still exist as abnormally high-pressured gas reservoir or free (adsorbed) gases in shallower strata when they are outside of the gas hydrate stable zone. Because of variation of gas source types and supply conditions, migration and accumulation conditions, and range of gas hydrate stability zone, these factors’matching relation is various at different location, which affects occurrence and distribution of gas hydrate in a horizontal plane and vertical profile in this area

Abstract: Marginal basins in the northern area of South China Sea have abundant natural gas resources. Not only a large amount of oilfield have been found in the shallow water of the northern area, but also great exploration breakthroughs of deepwater oil and gas have been made in the deep water of the southern area so far. A large number of biogenetic gas, sub-biogenetic gas and gas hydrate have been discovered in submarine and shallow layers of the deep water area. This paper, based on a large number of geochemical data of natural gas which received from gas exploration in recent years, as well as combining hydrocarbon accumulation geological conditions, makes a depth analysis and elucidation of the geological and geochemical characteristics of biogenetic gas and sub-biogenetic gas and the distribution feature of hydrocarbon source rocks in Neogene and Quaternary of Pearl River Mouth Basin in the northeast of South China Sea. On this basis, we preliminarily predict and estimate the generation amount and resource extent of biogenetic gas in Pearl River Mouth Basin. At the same time, by geochemical and geological analysis on the genetic type of gas hydrate at the deep water area in Baiyun sag in the southern area of Pearl River Mouth Basin, we further confirm that the gas hydrate discovered so far belongs to self-source diffusion model and biogenic mineralization hydrates type ,whose gas source is a kind of mixture dominated by biogenetic gas coming from original place and nearby, while the mineralization and accumulation model of gas hydrate can be classified into near-source migrated and accumulated model of self-generation and self-reservoir, which has tremendous resource potential

Abstract: 摘要: 根据在青海木里三露天施工完成的14 口天然气水合物钻孔揭露的地质信息,从天然气水合物产出、赋存、空间展布3个方面介绍工作区天然气水合物基本特征。此外,文章还以岩性特征、空间展布、裂隙、岩石物性多元控制因素 间相互制约和促进的内在联系为桥梁建立了天然气水合物储层这一研究对象。从储层方面分析,受岩相的控制作用三露天天然气水合物在空间上的分布有一定的选择性、延展性和可追索性, 即其储层具有相对稳定性;三露天天然气水合物在储层内部的分布除了受有利储层产状变化限制外,还受到裂隙产状的控制,致使其在空间上分布既不规则、又往往突然消失或突然出现。
Abstract: Based on the geological information derived from 14 gas hydrate drilling holes in Sanlutian of Muli,Qinghai, the basic features of gas hydrates’output, occurrence and spatial distribution are analyzed in this paper. According to the inner connection between inter-restriction and inter-stimulation of multivariate control factors, which is taken as a bridge, the gas hydrate reservoir is introduced as a study subject. From the aspects of reservoir analysis, it shows that the gas hydrate is controlled by lithofacies, which makes its spatial distribution appear to be selective, extensile and comparable to some extent, namely the relative stability of its reservoir appearance in Sanlutian. The gas hydrate distribution in the interior reservoir is also controlled by various occurrence of fracture besides the various occurrence of the reservoir in Sanlutian, leading to irregular distribution in space and frequently sudden disappearance or sudden appearance of gas hydrate

Abstract: Since the first drilling discovery of gas hydrate samples in Muli of Qilian Mountain permafrost in 2008, the gas source problem has become the focus. On the basis of previous work, the analysis of gas composition and methane carbon and hydrogen isotopes in adsorbed gases from cores, and of gas composition in headspace gas from cores was conducted in the paper. Those samples were collected from the gas hydrate drillings which were invested by Shenhua project in Sanlutian of Muli. Combined with gas composition and methane carbon and hydrogen isotope feature of gas hydrate in the relevant drillings, the analytical results are to further explore the genesis and properties of gas source for gas hydrate in this area. The results show that the gas source in the study area is of mixed genesis. The gas source is mainly composed of microbial gas partially mixed with a small amount of thermo-genic gas in the eastern part of the study area. The gas source is mainly composed of thermo-genic gas and secondarily of some microbial gas with a small amount of coal-derived gas in the middle to east of the study area. The thermo-genic gas is characteristic of crude oil cracking gas, and partly of microbial transformation gas

Abstract: 摘要: 通过采集青海木里三露天天然气水合物钻孔岩心样品,对该区天然气水合物赋存层段的中侏罗统和上三叠统烃(气)源岩的有机地球化学特征进行了分析。结果显示:研究区中侏罗统和上三叠统烃(气)源岩有机质丰度较高,TOC含量多在0.6%以上,即整体上为中等、好、很好烃源岩;有机质类型两套地层均主要以Ⅱ2型、Ⅲ型为主;两套地层 样品镜质体反射率多数介于0.7%~1.3%之间,只有少部分样品镜质体反射率低于0.7%,故有机质演化整体处于成熟阶段,或处于凝析油阶段,还没有达到湿气和干气阶段,可能只为该区天然气水合物提供一定量的气源条件,其主力气源岩可能来自更深部层系;研究区上三叠统烃(气)源岩有机质成熟度整体不高甚至低于中侏罗统,可能受断层逆推作用而出露地表的影响。
Abstract: The organic geochemical indicators were analyzed emphatically on the hydrocarbon (gas) source rocks of the Middle Jurassic and the Upper Triassic in gas hydrate occurrence interval in Sanlutian area of Muli,Qinghai. Results showed that the organic matter contents are at high levels in hydrocarbon (gas) source rocks of the Middle Jurassic and the Upper Triassic in the study area. Most TOC contents are more than 0.6%, that is medium, good and very good source rocks.The main organic matter is typed II2 and Ⅲ. The vitrinite reflectance of most samples are between 0 .7% to 1.3% and only a small part of the vitrinite reflectances are less than 0.7%. So the organic matter in most samples are at mature levels, or at condensate levels, not reach the level of wet to dry gas.This kind of gas source rocks may not produce large amounts of hydrocarbon gases to meet the prerequisite formation conditions for gas hydrate in the study area.The maturity of organic matter in the Upper Triassic is not high, even lower than that in the Middle Jurassic in the study area, which is probably caused by ground or shallow occurrence of the Upper Triassic reversed by faults
