“…These surface reactions include electrochemistry at liquid/solid interfaces [1][2][3], heterogeneous catalyses such as hydrogen production by catalytic reforming [4], rock weathering, and corrosion of metals [5]. The properties of the liquid at the solid interface also significantly impact the liquid's heat transfer [6] and flow characteristics on the solid surface, especially in smallscale spaces-for example, micro-nano-scale pipe flow [7,8] and nonlinear seepage [9] in reservoirs, and other issues. Despite the importance of solid-liquid interfacial science, much anomalous behaviour of the liquids on solid surfaces is still far from being thoroughly researched, with many new phenomena yet to be discovered and understood.…”

“…From these studies, the research has shown that certain structural characteristics and properties of the liquid on the solid surface undergo a change. For example, high-density water at the solid-liquid interface [9,10], ice-like water on the solid surface [11,12], ordered water at the solid-liquid interface [13][14][15], stable two-dimensional ice at room temperature [16], structured water and alkane layer at the solid interface [17,18], water with abnormal dielectric constant [19], and interfacial water and alkane with small self-diffusion coefficient [20,21].…”

Anomalous solid-like liquids at the solid–liquid interface have been recently reported. The mechanistic factors contributing to these anomalous liquids and whether they can stably exist at high vacuum are interesting, yet unexplored, questions. In this paper, thin slices of silica tubes soaked in hexadecane were observed under a transmission electron microscope at room temperature. The H-spectrum of hexadecane in the microtubules was measured by nuclear magnetic resonance. On the interior surface of these silica tubes, 0.2–30 μm in inside diameter (ID), a layer (12–400 nm) of a type of non-volatile hexadecane was found with thickness inversely correlated with the tube ID. A sample of this anomalous hexadecane in microtubules 0.4 μm in ID was found to be formable by an ion beam. Compared with the nuclear magnetic resonance H-spectroscopy of conventional hexadecane, the characteristic peaks of this abnormal hexadecane were shifted to the high field with a broader characteristic peak, nuclear magnetic resonance hydrogen spectroscopy spectral features typical of that of solids. The surface density of these abnormal hexadecanes was found to be positively correlated with the silanol groups found on the interior silica microtubular surface. This positive correlation indicates that the high-density aggregation of silanol is an essential factor for forming the abnormal hexadecane reported in this paper.

Due to the low permeability of tight reservoirs, throats play a significant role in controlling fluid flow. Although many studies have been conducted to investigate fluid flow in throats in the microscale domain, comparatively fewer works have been devoted to study the effect of adsorption boundary layer (ABL) in throats based on the digital rock method. By considering an ABL, we investigate its effects on fluid flow. We build digital rock model based on computed tomography technology. Then, microscopic pore structures are extracted with watershed segmentation and pore geometries are meshed through Delaunay triangulation approach. Finally, using the meshed digital simulation model and finite element method, we investigate the effects of viscosity and thickness of ABL on microscale flow. Our results demonstrate that viscosity and thickness of ABL are major factors that significantly hinder fluid flow in throats.

“…7,8 The boundary layer thickness can be affected by the pore throat radius, fluid properties, and experimental conditions. 58 In the tight rocks, the magnitude of the boundary layer thickness can be close to that of the average size of pores, and the nonflowing boundary layer causes a narrowed flow area to transmit the formation fluids. A number of models have been proposed to describe the boundary layer effect such as the analysis method of Li et al (2015), and several empirical models have been given for calculating the boundary layer thickness in tight formations.…”

The multiphase fluid flow in the tight rocks can be affected by the existence of the dynamic effect, boundary slip, and boundary layer. In this work, a fractal bundle of the capillary tube model is proposed to incorporate the above-mentioned factors into the two-phase fluid flow characterization in tight porous media. The model has been successfully validated by the experimental data from core-flooding tests, demonstrating its effectiveness to describe the production behavior in tight reservoirs. In addition, sensitivity analysis is conducted to quantify the effects of the dynamic effect, boundary slip, boundary layer, and injection pressure on the oil recovery of the tight formations. Results indicate that the dynamic effect and boundary layer should be taken into consideration when predicting the production behavior, while the boundary slip can be neglected. The predicted recovery can be as high as 23% higher than its actual value if neglecting the dynamic effect while the existence of the boundary layer can decrease the oil recovery by up to 7%.
