Nanostructure morphology and pore size distributions (PSDs) of 10 samples from the Lower Cambrian Niutitang Formation in northwestern Hunan were investigated using field emission scanning electron microscopy (FE-SEM), high-pressure mercury intrusion (HPMI), low-pressure nitrogen gas adsorption (LP-N2GA), carbon dioxide (LP-CO2GA). In combination with geochemical parameters mineral composition, factors influencing nanoscale structure analyzed. The results indicate that pores shale reservoirs...
The object of the study is lignite. Analytical testing techniques, such as elemental analysis, 13C nuclear magnetic resonance (13C NMR) spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron (XPS), and high-resolution transmission electron microscopy (HRTEM), were used to acquire information on structural parameters aromaticity Xianfeng lignite 43.57%, aromatic carbon structure mainly naphthalene anthracene/phenanthrene. aliphatic dominated by cycloalkanes, alkyl...
Methane adsorption experiments over wide ranges of pressure (up to 30 MPa) and temperature (30–120 °C) were performed using a gravimetric method on the Longmaxi shale collected from northeast boundary Sichuan Basin, China. Organic geochemical analyses, composition determination, porosity tests also conducted. The experimental supercritical methane excess isotherms at different temperatures initially increase then decrease with increasing pressure, giving maximum capacity (Gexm = 1.86–2.87...
Fine characterization of pore systems and heterogeneity shale reservoirs are significant contents gas reservoir physical property research. The research on micro-control factors low productivity in the Qiongzhusi Formation (Fm.) is still controversial. lower Cambrian Fm. Qujing, Yunnan was taken as object to investigate influence mineral compositions properties shale, using algorithm improve ability Atomic Force Microscopy (AFM). results showed that: (1) pores mainly wedge-shaped V-shaped...
The microscopic structure of the pore system in fine-grained mudrocks provides spaces for hydrocarbon percolation, migration, and occurrence. It exhibits strong heterogeneity due to intimate mingling organic matter (OM) inorganic minerals intricate architecture internal network dynamic changes along diagenetic pathway OM thermal maturation. present review critically summarizes advances characterization, geological controlling factors, mudrocks. can be divided into micro-, meso-, macropores...
Coalbed methane (CBM) and shale gas become two most important unconventional natural resources in US. The fractal dimension, known as the degree of self-similarity or irregularity, is an parameter to quantitatively characterize storage capacity transport properties pores rock matrix. In this study, coal samples were evaluated estimate dimensions using combined small angle X-ray scattering (SAXS), neutron (SANS) low-pressure N2 adsorption techniques. results show that surface dimension D s...
The chemical and alignment structures of coal impacts coalbed methane behavior: adsorption, desorption, diffusion. Recently, the research on accurate characterization techniques for structure has received widespread attention. In particular, spatial is critical molecular modeling coal. However, due to great challenges quantification, often been ignored in previous studies. this study, high-resolution transmission electron microscopy (HRTEM) was employed quantitatively characterize fringe...
The abundant nanopores in shale make it an unconventional reservoir for oil and gas. Matrix compressibility heterogeneity are crucial fluid accumulation migration, yet these two properties remain unclear reservoirs. Herein, we investigated the matrix compressibility, multifractal properties, their geological governing factors nanoporous Yanchang from Ordos Basin, China, utilizing petrophysical experiments, mercury injection capillary pressure (MICP), low-pressure gas adsorption. Furthermore,...
