Hence, based on the analysis of thin section, scanning electron microscope and physical property testing, this study focuses on the diagenesis characteristics and diagenetic evolution process of Chang 8 tight sandstone in southwestern Ordos basin.
The ease of access, fast image acquisition time, thin section scanning and multiplanar reformations make MDCT the ideal imaging modality.
The tabulation summarizes the results of two diagenesis studies based on analyses of thin sections, scanning electron microscope images, cores and cuttings samples.
In this paper, through outcrop and indoor core observation and analysis of thin sections, casting thin sections, scanning electron microscopy, we take the semi-weathered rock layer of unconformity at lower Jurassic in Xiazijie area of Junggar Basin as an example to discuss the diagenetic characteristics of the unconformable semi-weathered rock layer.
In this paper, based on a comprehensive analysis of well cores, thin sections, casting thin sections, scanning electron microscopy and other data, we discussed the diagenetic characteristics and the influences on reservoir physical properties of unconformity of the lower Jurassic in Xiazijie area, Junggar Basin.
The effects of pore throat structure on gas permeability in tight sand reservoir were investigated using helium-measured porosity, pulse decay permeability, casting thin sections, scanning electron microscopy (SEM), nuclear magnetic resonance (NMR), and constant-rate mercury injection for five sandstone samples from the Upper Triassic Yanchang Formation in the Western Ordos Basin, China.
Thin-section scans with 1-mm collimation were obtained at 10-mm intervals through the chest (Somaton Plus, Siemens, Erlangen, Germany).
Methods Institutional patient databases were searched to identify previously untreated patients with > two thin section CT scans showing a growing lung lesion, for which subsequent tissue diagnosis was obtained.
The analysis of thin section and scanning electron microscope suggests that intergranular pore, intergranular dissolution pore and feldspar or debris dissolution pore are the main pore types of Chang 8 sandstone in study area, and the average rate of face porosity is about 4.69%.
Initial imaging investigation of recurrent bacterial meningitis should include a contrast enhanced thin section CT scan of the temporal bone and anterior skull base, including the paranasal sinuses and an MRI imaging to detect CSF leakage.
Soiling mechanisms which are analyzed in artificially soiled samples with imaging techniques (thin sections and scanning electron microscopy) and their relevance to acoustical parameters are shown.
