The deep metamorphic rock gas reservoir in the central paleo-uplift of the northern Songliao Basin has good exploration and development potential. In this study, we use a combination of qualitative descriptions and quantitative analysis to comprehensively analyze the pore characteristics of the reservoir and explore the factors controlling the pore characteristics of the metamorphic rock reservoir in the central paleo-uplift belt of the Songliao Basin. The metamorphic rock reservoir in the central paleo-uplift belt contains three types of lithologies: chlorite schist, mica schist and mylonite, each with different protoliths and metamorphic histories. The results of high-pressure mercury intrusion and nitrogen adsorption indicate that the pore size distributions of the schist and mylonite differ. Compared with the mylonite, the schist has larger reservoir space, more heterogeneity, smaller pore size, larger specific surface area and larger adsorbed gas storage capacity. This paper also studies the formation process of the reservoir and divides it into four stages. Finally, this article discusses in detail the factors controlling the microscopic pore characteristics of metamorphic rock reservoirs in the central paleo-uplift belt; the metamorphic rock protolith is the most important controlling factor.}, year = {2022}, eissn = {2045-2322} } @misc{MTMT:32389153, title = {Semiquantitative Characterizations And Controlling Factors of Microscopic Pore Characteristics of The Metamorphic Rock Reservoir In The Central Paleo-Uplift Belt, Songliao Basin}, url = {https://m2.mtmt.hu/api/publication/32389153}, author = {Zhouqiang, Zeng and Xuanlong, Shan and Guoli, Hao and Wentong, He and Changqing, Zheng and Jian, Yi and Jiannan, Guo}, unique-id = {32389153}, year = {2021} } @article{MTMT:31453490, title = {Lithofacies characteristics and their controlling effects on reservoirs in buried hills of metamorphic rocks: A case study of late Paleozoic units in the Aryskum depression, South Turgay Basin, Kazakhstan}, url = {https://m2.mtmt.hu/api/publication/31453490}, author = {Han, Changcheng and Tian, Jijun and Hu, Chenlin and Liu, Hailei and Wang, Wenfeng and Huan, Zhipeng and Feng, Shuo}, doi = {10.1016/j.petrol.2020.107137}, journal-iso = {J PETROL SCI ENG}, journal = {JOURNAL OF PETROLEUM SCIENCE AND ENGINEERING}, volume = {191}, unique-id = {31453490}, issn = {0920-4105}, abstract = {Metamorphic rock reservoirs are special reservoirs that are quite different from traditional sedimentary rock reservoirs and contain rich hydrocarbon reserves. However, their lithofacies characteristics and reservoir properties are relatively underexplored, and the key factor in reservoirs is lithofacies. Based on core samples, thin sections, whole-rock analysis and well-log and seismic data, we evaluated the lithologies, petrological characteristics and reservoir properties of metamorphic rocks and then explored the main factors controlling reservoir formation and metamorphic rock quality in the Aryskum depression, South Turgay Basin, Kazakhstan. In this area, four types of lithofacies are identified: granitic gneiss (high DEN and CN, low GR), leptite (high GR and CN), gabbro (low GR and CN) and granite (high GR and low CN); among these rocks, granitic gneiss is widely distributed. The reservoir spaces of metamorphic rocks are divided into fractures and pores produced via metamorphism and structural movements. Fractures can be subdivided into structural fractures (SFs), dissolution fractures (DFs), cleavage microfissures (CMfs) and microfissures (Mfs), and pores include dissolved intergranular pores (DInterPs), dissolved intragranular pores (DIntrPs) and vugs (Vgs). Numerous SFs and DFs provide the main reservoir spaces for hydrocarbons. The reservoir quality of metamorphic rocks is primarily controlled by faults, fractures, lithofacies, minerals, dissolution and paleogeomorphology. Lithofacies and minerals are the internal factors that control dissolution and fragmentation, while paleogeomorphology and faults are the external factors that control fracture development. Leptite and granitic gneiss are high-quality reservoir lithofacies, and high paleogeomorphology areas and fault zones are the optimal locations for fractures and pores. Reservoir spaces undergo a series of repeated changes from formation to development, filling and reformation, and a comprehensive reservoir evolution model is proposed to illustrate the distribution of high-quality reservoirs. This study has scientific significance for investigating the reservoir-forming mechanisms of metamorphic rocks and practical applications for exploring and developing oil and gas fields in areas with metamorphic rocks.}, keywords = {Metamorphic rocks; reservoir properties; Lithofacies characters; Aryskum depression}, year = {2020}, eissn = {1873-4715} } @article{MTMT:27669308, title = {Dilatancy as a measure of fracturing development in the process of rock damage}, url = {https://m2.mtmt.hu/api/publication/27669308}, author = {Jerzy, Cieślik}, doi = {10.1515/geo-2018-0038.}, journal-iso = {OPEN GEOSCI}, journal = {OPEN GEOSCIENCES}, volume = {10}, unique-id = {27669308}, issn = {2391-5447}, year = {2018}, eissn = {2391-5447}, pages = {484-490} } @article{MTMT:25486536, title = {Identification of mineralized zones in the Zardu area, Kushk SEDEX deposit (Central Iran), based on geological and multifractal modeling}, url = {https://m2.mtmt.hu/api/publication/25486536}, author = {Dahooei, Ahmad Heidari and Afzal, Peyman and Lotfi, Mohammad and Jafarirad, Alireza}, doi = {10.1515/geo-2016-0014}, journal-iso = {OPEN GEOSCI}, journal = {OPEN GEOSCIENCES}, volume = {8}, unique-id = {25486536}, issn = {2391-5447}, year = {2016}, eissn = {2391-5447}, pages = {143-153} } @article{MTMT:2949640, title = {Localisation of ductile and brittle shear zones along the Szentlőrinc-1 well in the Mecsekalja Zone using quartz microstructural and well-log data}, url = {https://m2.mtmt.hu/api/publication/2949640}, author = {Skultéti, Ágnes and M.
