| 1 | Self-adjusted elastic action and its CBM pool-forming effect of the high rank coal reservoir显示文摘The coal reservoir is a kind of geologic body with considerable elasticity, and its response to stress is more sensitive than the routine ones. In the pool-forming process of the coalbed methane, (CBM) the action of many external geodynamic factors in the coal reservoir is represented by the ability of CBM’s diffusion and migration in the coal reservoir. Therefore, the occurrence of the natural fissures in the coal reservoir becomes a key that determines whether the CBM pool can be formed or not. Based on the principle, the authors have designed a comprehensive method of physical modeling to study the elasticity of the coal matrix block with different coal ranks in the light of the solid to fluid coupling, have established the model of the volume deformation (self-adjusted elastic effect) of the coal reservoir under the condition of the effective stress-adsorption/desorption, and have obtained a correct understanding of the law of the elastic deformation. Afterwards, a new viewpoint, named as the self-closing elastic effect for forming the CBM pool in the high rank reservoir, is put forward, providing an initial point and a scientific basis for a further investigation into its dynamic factors, possible mechanism and role in the CBM energy-balancing system. | QIN Yong FU Xuehai WU Caifang FU Guoyou BU Yingying | 2005 | Chinese Science Bulletin2005，50，S1： | 9 |
| 2 | The mechanism of the flowing ground water impacting on coalbed gas content显示文摘The hydrogeological condition affects the coal-bed gas storage dramatically. In an area of stronger hydrodynamics, the coal has a lower gas content, while a higher gas content exists in an area of weaker hydrodynamics. Obviously, the flowing groundwater is harmful to coalbed gas preservation. But few researches focus on the mechanism of how the flowing water diminishes the coalbed gas content Based on the phenomenon that the flowing groundwater not only makes coalbed gas content lower, but also fractionates the carbon isotope, this research puts forward an idea that it is the water solution that diminishes the coalbed gas content, rather than the water-driven action or the gas dissipation through cap rocks. Only water-soluble action can both fractionate the carbon isotope and lessen the coalbed gas content, and it is an efficient way to take gas away and affect the gas content. | QIN Shengfei SONG Yan TANG Xiuyi FU Guoyou | 2005 | Chinese Science Bulletin2005，50，S1： | 3 |
| 3 | Dissection of heterosis for yield and related traits using populations derived from introgression lines in rice显示文摘Despite the great success achieved by the exploitation of heterosis in rice,the genetic basis of heterosis is still not well understood.We adopted an advanced-backcross breeding strategy to dissect the genetic basis of heterosis for yield and eight related traits.Four testcross(TC) populations with 228 testcross F1 combinations were developed by crossing57 introgression lines with four types of widely used male sterile lines using a North Carolina II mating design.Analysis of variance indicated that the effects of testcross F1 combinations and their parents were significant or highly significant for most of the traits in both years,and all interaction effects with year were significant for most of the traits.Positive midparent heterosis(HMP) was observed for most traits in the four TC populations in the two years.The relative HMPlevels for most traits varied from highly negative to highly positive.Sixty-two dominant-effect QTL were identified for HMPof the nine traits in the four TC populations in the two years.Of these,22 QTL were also identified for the performance of testcross F1.Most dominant-effect QTL could individually explain more than 10% of the phenotypic variation.Four QTL clusters were observed including the region surrounding the RM9–RM297 region on chromosome 1,the RM110–RM279–RM8–RM5699–RM452 region on chromosome 2,the RM5463 locus on chromosome 6 and the RM1146–RM147 region on chromosome 10.The identified QTL for heterosis provide valuable information for dissecting the genetic basis of heterosis. | Chao Xiang Hongjun Zhang Hui Wang Shaobo Wei Binying Fu Jiafa Xia Zefu Li Yongming Gao Guoyou Ye | 2016 | The Crop Journal2016，4，6： | 3 |
| 4 | Abnormal overpressure distribution and natural gas accumulation in foreland basins, Western China显示文摘Abnormal overpressure occurs in the forelandbasins of Kuqa, South Junggar and West Sichuan in China.The pressure coefficients are high. Overpressure exists inwide areas and various strata. The layers of overpressurehave a very close relationship with lithology, and the area ofoverpressure is controlled by the piedmont depression. Themechanisms of overpressure formation in the Kuqa andSouth Junggar Depression include disequilibrium compac-tion and tectonic compression; the importance of these twofactors varies in different basins and in different stages of thesame basin. Different models of gas accumulation are estab-lished to explain the relationship between overpressure dis-tribution and gas pool formation, and the influence of over-pressure on the gas pools. These models include: (i) theviolent tectonic movement leads to the pool formation inoverpressure belt (Kela-2 gas field in Kuqa); (ii) the pres-sure releases at shallow part and the gas pool forms in latetime (Hutubi gas field in southern Junggar Basin); (iii)through the pressure transfer the gas migrates and accumu-lates (Xinchang gas field in Western Sichuan Basin). | SONG Yan XIA Xinyu HONG Feng QIN Shengfei FU Guoyou | 2002 | Chinese Science Bulletin2002，47，S1： | 3 |
| 5 | Study on process and model of CBM dissipating显示文摘Coal Bed Methane(CBM) occurs in coal seams in the states of adsorption gas, free gas and water-dissolved gas. Its dissipating starts with desorption, and then it dissipates outwards in the states of free gas and water-dissolved gas. The dissipating approach is classified to three patterns: Free gas in pores dissipates through the cover rocks; hydrocarbon molecules in the cap-rocks and reservoir diffuse because of concentration gradient; gas dissolving in water is directly taken away by water. According to the controlling factors of CBM conservation and considering the cover rocks, soleplate, hydrological region identification and dissipating theory, three geological models of CBM dissipating are built: closed system model, lateral hydrological closed model and open system model. | Feng Hong Yan Song Zhenhong Chen Mengjun Zhao Shaobo Liu Shengfei Qin Guoyou Fu | 2005 | Chinese Science Bulletin2005，50，S1： | 1 |
