“…Most MPs are on the nanometer scale, and their origins are currently being debated. MPs may include the tiny intergranular pores between matrix grains, or the DPs formed by eogenetic dissolution [52,53]. The high MP content resulted in a poor connection between the porosity-permeability and complicated pore network structures.…”

The goal of this study was to investigate the impacts of various sedimentary-diagenetic conditions on the macroscopic petrophysical parameters and microscopic pore structures of tight sandstones from the Lower Jurassic Badaowan Formation in the Southern Junggar Basin, China. Based on the traditional methods for establishing pore size distribution, including integrating the results of high-pressure mercury injection, nuclear magnetic resonance, and scanning electron microscopy, the constrained least squares algorithm was employed to automatically determine the porosity contributions of pore types with different origins. The results show that there are six genetic pore types: residual intergranular pores (RIPs), feldspar dissolution pores (FDPs), rock fragment dissolution pores (RFDPs), clay mineral intergranular pores (CIPs), intercrystalline pores of kaolinite (IPKs), and matrix pores (MPs). Four lithofacies were identified: the quartz cemented-dissolution facies (QCDF), carbonate cemented facies (CCF), authigenic clay mineral facies (ACMF), and matrix-caused tightly compacted facies (MCTF). Modified by limited dissolution, the QCDF with a high proportion of macropores (RIPs, FDPs, and RFDPs) exhibited a slightly higher porosity and considerably higher permeability than those of others. A large number of micropores (MPs, CIPs, and IPKs) in MCTF and ACMF led to slightly lower porosities but considerably lower permeabilities. Due to the tightly cemented carbonates in the CCF, its porosity reduced sharply, but the permeability of the CCF remained much higher those of the MCTF and ACMF. The results highlight that a high proportion of macropores with large radii and regular shapes provide more effective percolation paths than storage spaces. Nevertheless, micropores with small radii and complex pore structures have a limited contribution to flow capability. The fractal dimension analysis shows that a high proportion of MPs is the major reason for the heterogeneity in tight sandstones. The formation of larger macropores with smooth surfaces are more conductive for oil and gas accumulation.

“…The flu vial/deltaic or i gin of the Car bon if er ous rocks from the Lublin Ba sin was in ter preted and widely dis cussed by Waksmundzka (2010). High flow ve loc ity and in tense ero sion in braided river channels (CH) and distributary chan nels of a delta plain (DCH) are rea sons why these sand stones are better sorted and there fore char ac ter ized by lower clay and mus co vite con tents; thus, this type of rock usu ally has higher pri mary po ros ity and shows better res er voir prop er ties (Liu et al, 2015;Fan et al, 2019). How ever, this struc ture is also fa vour able for the per co la tion of diagenetic flu ids which can be a fur ther rea son for po ros ity reduc tion (Yang et al, 2014).…”

“…Sedimentary facies control the lithology and original petrophysical property of the reservoir that are the foundation of all subsequent diagenetic changes (Burley, Kantorowicz, & Waugh, 1985;Hammer, Mørk, & Naess, 2010;Khalifa & Morad, 2012;Khalifa & Morad, 2015;Luo et al, 2009;Morad et al, 2010;Morad et al, 2012;Morad, Ketzer, & de Ros, 2000;Salem, Morad, Mato, & Al-Aasm, 2000). Nevertheless, different diagenetic processes have different influence on sandstone reservoir quality (Fan et al, 2019;Fan, Yang, Li, Zhao, & van Loon, 2017;Worden & Morad, 2002;Yang, Fan, Van Loon, Han, & Wang, 2014). Up to a depth of 2 km, compaction is the main mechanism of primary pore loss in clastic reservoirs (Khidir & Catuneanu, 2010;Marcussen, Maast, Mondol, Jahren, & Bjørlykke, 2010;Paxton, Szabo, Ajdukiewicz, & Klimentidis, 2002;Peltonen, Marcussen, Bjørlykke, & Jahren, 2009).…”

The sedimentary characteristics and petrophysical properties of the reservoir of the second/lower member of the Lower Permian Shanxi Formation (P 1 s 2 ) in Sulige Gas Field, Central China are studied by means of thin section petrography and scanning electron microscopy. This article highlights the relationship between reservoir quality and sedimentary environments, explains the differences in reservoir petrophysical properties in different sedimentary environments, discusses the influence of clastic components and authigenic minerals on the reservoir, and finally, provides the basis for the prediction of relatively high-quality reservoir in P 1 s 2 of the study area. The results show that the sandstones formed as a meandering river deposit in the south of the study area are fine-grained, mainly composed of lithic fragments of quartz sandstone, metamorphic, and volcanic rock lithic fragment, with high content of matrix and poor sorting, average porosity of 5.09%, and average permeability of 0.20 × 10 −3 μm 2 . The braided river sedimentary deposits in the north are coarsegrained, mainly composed of quartz sandstone sedimentary rock lithic fragment, with low content of matrix, good sorting, and more developed dissolution pores. The average porosity is 6.16%, and the average permeability is 0.53 × 10 −3 μm 2 . Among the authigenic minerals, siderite, calcite, and illite block, the pores between the grains reduce the porosity. Siliceous cement often indicates better reservoir petrophysical properties. The siliceous cement is more common in braided river deposits in the north area, in which the channel bar detailed facies are conducive to retain more primary pores or form secondary pores, thus forming better reservoirs.
