近年来,鄂尔多斯盆地东南部上古生界天然气勘探取得了重大突破。为了明晰该区上古生界天然气的成藏过程,以区内延安气田上古生界气藏主力产层--下二叠统山西组为例,通过对储层流体包裹体颜色、形态、成分、均一温度等特征的分析,结合埋... 近年来,鄂尔多斯盆地东南部上古生界天然气勘探取得了重大突破。为了明晰该区上古生界天然气的成藏过程,以区内延安气田上古生界气藏主力产层--下二叠统山西组为例,通过对储层流体包裹体颜色、形态、成分、均一温度等特征的分析,结合埋藏史、热史模拟,确定了包裹体形成期次,厘定了烃类充注的地质年代,分析了油气充注与成岩演化的耦合关系。研究结果表明:①延安气田山西组储层流体包裹体主要赋存于自生石英、碳酸盐胶结物及石英颗粒愈合缝中,有CO2、烃类和盐水3种类型的包裹体。②烃类包裹体的形成主要有两期,其中第一期主要发育在石英次生加大边和石英颗粒愈合缝中,均一温度介于90~110℃,气态烃组分以富CO2和CH4为主;第二期主要发育在石英加大边、碳酸盐胶结物及石英颗粒愈合缝中,均一温度介于130~160℃,气态烃组分以富CH4为主。③山西组存在着两期烃类充注,其中第一期发生在晚三叠世-早、中侏罗世,该时期有机质开始生排烃并充注,长石和岩屑溶蚀形成次生孔隙,化学压溶作用开始发生并形成少量石英加大边;中、晚侏罗世,烃源岩进入成熟阶段,开始大量生排烃并开始第二期烃类充注,化学压溶作用加强,石英胶结大量发育;至早白垩世,烃源岩热演化达到高-过成熟阶段,大量生气,石英胶结继续发育,铁白云石发生沉淀;早白垩世末至今,烃源岩生烃作用逐渐停止。 展开更多

Objective: The aim of the study was to evaluate the safety and therapeutic effects of autologous dendritic cells co-cultured with cytokine-induced killer cells (DC-CIK) combined with chemotherapy in advanced non-small cell lung cancer (NSCLC) patients. Methods: Fifty patients with advanced NSCLC (stages III to IV), who had received therapies in our Center (Department of Biotherapy, Affiliated to Cancer Hospital of Shanxi Medical University, Taiyuan, China) from August 2008 to January 2010, were treated by DC-CIK + chemotherapy as the combined treatment group; fifty advanced NSCLC patients treated with chemotherapy at the same time served as controls. The immunologic function, short-term therapeutic effects, the 1-year survival rate, the life quality, the chemotherapy side effects were compared between the two groups, the safety and therapeutic effects of DC-CIK cells therapy were observed too. Results: There was no obvious change of subsets of T cells in peripheral blood before and after therapy in DC-CIK + chemotherapy group, and IFN-γ was improved after therapy in this group (P < 0.05); in chemotherapy alone group, the ratios of CD3+CD4+, CD3+CD8+, CD3-CD56+ cells and the secretion of IL-2, TNF-α decreased significantly after therapy (P < 0.05); the ratios of CD3+CD8+, CD3+CD56+ were improved after cell culture (P < 0.05). The disease control rate (DCR) of DC-CIK + chemotherapy group was higher than that in the chemotherapy alone group (78.0% vs 56.0%, P < 0.05); the 1-year survival rates of DC-CIK + chemotherapy group and chemotherapy alone group were 50% and 44% respectively, had no significant difference. Compared with chemotherapy alone group, the occurrence of chemotherapy side effects (including bone marrow suppression, nausea and vomiting, peripheral nerve toxicity) was less in the DC-CIK + chemotherapy group (P < 0.05). The physical and appetite were better in DC-CIK + chemotherapy group after therapy. Conclusion: To compare with simple chemotherapy, DC-CIK + chemotherapy for advanced NSCLC is safe and effective, and it can improve patients' life quality and remission rate, and prolong their survival time. 展开更多

Landslides not only cause property losses,but also kill and injure large numbers of people every year in the mountainous areas. These losses and casualties may be avoided to some extent by early warning systems for landslides. In this paper, a realtime monitoring network and a computer-aided automatic early warning system(EWS) are presented with details of their design and an example of application in the Longjingwan landslide, Kaiyang County, Guizhou Province. Then, according to principle simple method of landslide prediction, the setting of alarm levels and the design of appropriate counter-measures are presented. A four-level early warning system(Zero, Outlook, Attention and Warning) has been adopted, and the velocity threshold was selected as the main warning threshold for the landslide occurrence, but expert judgment is included in the EWS to avoid false alarms. A case study shows the applicability and reliability for landslide risk management, and recommendations are presented for other similar projects. 展开更多

During an excavation survey to the Daijiayuan vestige of the Western Zhou Dynasty-Late Spring and Autumn Period at Huoshan in Western Anhui,a ground crack related to tectonic movement and filled with silty fine sand was found. This phenomenon was initially confirmed to be due to seismic liquefaction. Many microscopic seismic relics,such as load structure,flow structure,cutoff plane and flotation of organic matter were found in the directional microscopic analysis of deformation. These discoveries and cognitions prove that there were two earthquake events taking place in the Western Zhou Dynasty-Late Spring and Autumn Period in this area. Above-mentioned works enrich and develop the research methods to identify prehistoric earthquake event in eastern China area to a certain extent. 展开更多
