| 2 | Formation mechanism of high-quality reservoirs in intermediate volcanic rocks:A case study of Longfengshan area in Songliao Basin显示文摘The basin margin slope area of Changling fault depression in Songliao Basin is dominated by intermediate-basic volcanic rocks of Huoshiling Formation,and there is still a lack of in-depth understanding of the development pattern and formation mechanism of high-quality reservoirs in intermediate-basic volcanic rocks in this area.Taking the intermediate volcanic rocks in Longfengshan area of Changling fault depression as an example,a comprehensive study was undertaken via core observations,thin section porosity analysis,rock physical property tests,scanning electron microscopy and X-ray diffraction analysis,combined with well log and seismic d ata.As a result,formation mechanism of a high quality reservoir was made clear based on dissolution modification effects of the volcanic rocks,and the development model of the high quality reservoir under t he dual control of lithology and fluid was established.The research shows that the volcanic rocks in this area consist of six lithologies:andesitic hydrothermal breccia,andesite,andesitic volcanic breccia,andesitic tuff,dacitic tuff and sedimentary tuff,which are controlled by structure,eruptive source,eruptive action and palaeotopography.The proximal facies of the volcanic edifice were located on the basin margin,distributed along faults mainly consisting of overflow facies intermixed with eruptive facies,and gradually transformed into thick eruptive facies(middle-source facies)and volcanic sedimentary facies(distal facies).The reservoir space of volcanic rocks was dominated by dissolution pores,which were formed by weathering and dissolution by organic acidic fluids.The thermal debris flow subphase in the middle-source facies of the volcanic edifice had a large amount of easily dissolved volcanic ash,which was close to the source rock in the centre of the basin and was a favourable area for the development of dissolution pores.This study is providing a guide for oil and gas exploration in the intermediate-basic volcanic rocks in the slope of Changling fault depression in Songliao Basin. | XING Jian SHAN Xuanlong REN Xianjun YI Jian LIU Chaoyang NIU Penghui | 2022 | Global Geology2022，25，2： | 1 |

| 4 | Differentiation of rat oligodendrocyte precursor cells in chemical conditional medium in vitro显示文摘Objective: To investigate in vitro differentiation of oligodendrocyte precursor cells (OPCs) into mature oligodendrocytes in chemical conditional medium. Methods: The mixed glial cells from cerebral cortices of 48-hour-old Sprague-Dawley (SD) rats were cultured in vitro. The OPCs were separated by shaking procedure around 9–10 d in the primary culture. Then the isolated OPCs were further transferred into the chemical conditional medium for cell differentiation. The pattern of OPCs maturation in vitro was continuously observed with contrast phase microscopy and mature oligodendrocytes were further identified by immunocytochemical assays. Results: OPCs grew well when co-cultured with glial cells and distinct cellular stratification formed about 9–10 d in the primary culture, which indicated the appropriate opportunity for the separation of OPCs. Following cultured in the chemical conditional medium, the OPCs progressively differentiated into the mature oligodendrocytes. These mature oligodendrocytes were also immunostained with the oligodendrocyte lineage-specific antibody, Oligo2. Conclusion: The OPCs isolated from the cerebral cortices of neonatal SD rats can progressively differentiate into mature oligodendrocytes in the chemical conditional medium in vitro. | Wu Bo Ye Feng Ren Xianjun | 2008 | Journal of Medical Colleges of PLA(China)2008，23，4： | 0 |
| 5 | Microscopic pore characteristics of andesite and implication from mineral content:A case study in Huoshiling Formation of Changling fault depression,Songliao Basin显示文摘In order to study the microscopic pore characteristics of andesite reservoir and the effect of mineral content on the andesite pore,this study takes the andesite of the Huoshiling Formation in Longfengshan of Changling fault depression,Songliao Basin as a subject.The andesite reservoir space was discerned through the observation of cores and casting thin sections.Besides,the pore size distribution of andesites and their mineral contents were quantitatively characterized by high-pressure mercury injection,nitrogen adsorption and XRD,respectively.The results show that:(1)There are various types of reservoir space in andesites,including vesicles,amygdule,intergranular pores,matrix dissolution pores and dissolution pores of amygdala,and three types of fractures including dissolution,structural and explosion fractures.(2)The pore size distribution of andesite is complex.The main pore size of andesite is mid-pore(10-20 nm)with some large-pores(>50 nm).Mid-pore and large-pore provide the main specific surface area,which are the main space for gas storage.(3)The andesite reservoir space in the study area is mainly controlled by dissolution,as supported by the relationship between the change of mineral content and porosity evolution.The porosity of andesites decreases with the increase of quartz and chlorite content,but increases with the increase of soluble mineral,e.g.,feldspar content. | NIU Penghui SHAN Xuanlong REN Xianjun YI Jian LIU Chaoyang XING Jian | 2022 | Global Geology2022，25，2： | 0 |
