It is shown that the metamorphic buried hill reservoir is mainly distributed in the metamorphic glutenite, schist, cataclastic granite, mylonite. The reservoir is mainly divided into two types: weathered crust and inner layer. The weathered crust reservoir is developed at the top of the uplift zone, mainly developed dissolution fractures and broken intergranular pores; the lower part of the weathered crust is an insider type reservoir, which can be divided into two sets (insider I and insider II) under the influence of different longitudinal lithology. In insider I, structural fractures (1.1%~3.2%), intergranular pores (0.3%~1.4%) and intragranular corrosion pores (0.1%~0.8%) are mainly developed; in insider II, foliation fractures (0.5%~1.2%) and local intragranular dissolution pores (0.3%~0.7%) are mainly developed. The physical property and gas bearing property of weathered crust type reservoir are better than that of inside type reservoir. The main forming mechanism of metamorphic buried hill reservoir in the study area is dissolution and uplift extrusion. The main reason for the undevelopment of reservoir in deep insider I is that the reservoir pores are reduced or even completely filled due to the burial depth and hydrothermal process. © 2020, the Editorial Department of Journal of Xi'an Shiyou University.

Insights into palaeo fluid compositions complement observations on present day fluid compositions, which represent only the end-point of complex cumulative processes throughout basin history. In this contribution, we review a wide range of approaches used to extract geochemical information from petroleum inclusions, and how these can be used to better constrain petroleum systems. These techniques can be grouped into optical, spectrographic and thermometric non-destructive methods, or destructive chemical analyses of bulk samples or individual inclusions.Typically optical methods documenting the distribution and visual properties of petroleum inclusions are used to provide petrographic context for subsequent specialised geochemical analyses of petroleum inclusions. Additional non-destructive techniques such as Raman spectroscopy can then be applied to provide some further insights into the composition of the trapped fluids, although the complex nature of petroleum generally requires direct access to the fluid for a more complete understanding of geochemical aspects. A variety of destructive techniques have been developed, initially to analyse bulk samples released by mechanical crushing and more recently through ablation type techniques that allow the composition of individual inclusions to be characterised.Screening geochemical techniques that utilise mechanical crushing of bulk samples to analyse petroleum inclusions using mass spectrometry without prior chromatographic separation have become routine analyses. Other geochemical techniques more geared towards detailed molecular information such as biomarkers utilise chromatographic separation prior to mass spectrometry. Evaluation of the isotopic composition of petroleum inclusions is also possible for both bulk samples and compound specific analyses.The use of lasers to open individual inclusions allows the released contents to be analysed by thermal extraction-gas chromatography-mass spectrometry (GC-MS), or mass spectrometric mapping of minerals using Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS), a surface-sensitive analytical method that uses ion beams to ablate into minerals.The continued evolution of techniques to analyse the incredibly small volume of hydrocarbons trapped within fluid inclusions has progressed to a point where there is little that can be done to evaluate a live oil or gas sample that cannot be achieved for a fluid inclusion sample. The full power for tracing petroleum systems is, however, only realised where there is an effective integration of fluid inclusion data with a more conventional approach to petroleum systems analysis.

The diabases are high-K calc-alkaline and belonging to the tholeiitic series, enriched in large ion lithophile elements, Ti, Zr and light rare earth elements, and depleted in high field strength elements. These characteristics are different from the oceanic island basalt but highly consistent with the continental rift basalt, indicating the Luoji and Cuiyi diabases are the products of the intracontinental rift related to the initial opening of the Ganzi-Litang Ocean. The Luoji and Cuiyi diabases originated from an enriched mantle source with a small degree of crustal contamination during their emplacement. Zircon U-Pb ages show that the Luoji and Cuiyi diabases were emplaced at 293.4±5.4Ma. Therefore, we propose that the time of initial rifting of the Ganzi-Litang Ocean occurred during the very Early Permian. © 2019, Croatian Geological Survey.

Some of these may give rise to subsurface vibrations that can potentially increase groundwater pollution risks in double-porosity systems. The more complicated situation was where underground storage tanks and petroleum pipeline damage have caused the leakage of non-aqueous phase liquids (NAPLs) which migrated into the groundwater resources. These problems need to be addressed by both professionals and researchers worldwide to ensure the sustainability of groundwater utilization. This paper aims to investigate and understand NAPL migration in vibrated double-porosity soils. To do so it was necessary to study the phenomena and characteristic of soil structure and the pattern of NAPL migration to identify cost-effective remediation schemes. A laboratory experiment was conducted to study the phenomena and characteristics of vibration response and NAPL migration in double-porosity soil deformation under vibration effect using a digital image processing technique (DIPT). The outcomes of the experiment show that the gradual increase of vibration table excitation frequency yielded different vibration responses from the respective soils. This indicated that soil surface acceleration depended significantly on the soil conditions, soil water content, soil structure and the pattern of soil fracturing. NAPL migration was faster in sample 2 with 150ml toluene than sample 1 with 70ml toluene and this could be because the greater amount of toluene in sample 2 exerted an extra entry force on top of the soil sample that had yet to migrate through the sample surface. Finally, it was concluded that the DIPT may provide detailed information, and can be used to understand and identify the remediation method as well as to ensure the sustainable consumption of groundwater.}, keywords = {VIBRATION; Laboratory experiment; NAPLs migration; aggregate kaolin; image analysis method}, year = {2018}, eissn = {1333-4875}, pages = {163-171} } @article{MTMT:3399845, title = {Pervasive early diagenetic dolomitization, subsequent hydrothermal alteration, and late stage hydrocarbon accumulation in a Middle Triassic carbonate sequence (Szeged Basin, SE Hungary)}, url = {https://m2.mtmt.hu/api/publication/3399845}, author = {Garaguly, István and Raucsikné Varga, Andrea Beáta and Raucsik, Béla and Schubert, Félix and Czuppon, György and Frei, R}, doi = {10.1016/j.marpetgeo.2018.07.024}, journal-iso = {MAR PETROL GEOL}, journal = {MARINE AND PETROLEUM GEOLOGY}, volume = {98}, unique-id = {3399845}, issn = {0264-8172}, year = {2018}, eissn = {1873-4073}, pages = {270-290}, orcid-numbers = {Garaguly, István/0000-0002-2802-0738; Raucsikné Varga, Andrea Beáta/0000-0002-8673-1482; Raucsik, Béla/0000-0002-1951-5974; Schubert, Félix/0000-0001-8647-5354; Czuppon, György/0000-0002-7231-6042} }
