Abstract Shale formations as major unconventional energy resources are crucial in satisfying the global needs of future. Via nanoindentation method and upscale method, macromechanical parameters shale, such hardness, elastic modulus, obtained. The conventional Mori–Tanaka only divides data into three mineral classes fails to fully incorporate micromechanical properties reflect macroscale samples. research measures shale via performs cluster analysis measurements. results then combined with...
Abstract Summary: A series of high clay content Laponite XLS/polyacrylamide (PAAm) nanocomposite hydrogels (S‐M gels) with excellent resilience, low elastic hysteresis, and ultrahigh elongation, have been successfully synthesized. Based on our results, it is concluded that the mechanical properties probably depend to a great extent hydrophilicity flexibility macromolecules. Moreover, found transparency during in‐situ polymerization S‐M gels does not change, which quite different from...
Characteristics of sorption and distribution water in nanoporous shale are topics great interest to evaluate unconventional reservoirs. Also, a study surface force water/solid interaction at nanoscale is significant for understanding the storage initial fate residual treatment liquid systems. In this work, thickness stability film were investigated by vapor experiments on clay samples. Meanwhile, an approach based forces (disjoining pressure), which resulted instability adsorbed transition...
Spontaneous imbibition of water-based fracturing fluids into the shale matrix is considered to be main mechanism responsible for high volume water loss during flowback period. Understanding capacity and rate helps determine fluid volume, optimize design, analyze influences on production gas. Imbibition experiments were conducted samples from Sichuan Basin, some tight sandstone Ordos Basin. Tight volcanic Songliao Basin also investigated comparison. The effects porosity, clay minerals,...
The quantitative characterization of adsorbed gas and free in shale reservoirs is a key issue exploration development gas. Thus, the aforementioned topic great significance to evaluation reserves, screening favorable target areas, formulation plans. However, research on our current understanding quantities deep still lacking. To address this problem, shales from Longmaxi Formation southern China were collected conduct high-pressure isothermal adsorption experiments. model was used describe...
The brittle minerals and shale bedding seriously affect the fracture performance of shale, macroscopic mechanical experimental methods cannot separate these key factors for analysis. In this study, nanoindentation tests were conducted on clay carbonate shales, effects felsic micromechanical characteristics evaluated.Based extended cavity model, analytical formulas energy density total function during indentation process layered discussed. results showed that with increase mineral content,...
Taking the Chang 8 tight sandstone reservoir of Yanchang Formation Fuxian area in Ordos Basin as an example, influencing mechanism permeability on imbibition recovery was explored by spontaneous experiment, combining nuclear magnetic resonance (NMR) and CT Scanning. Results show that: (1) played a vital role water–flooding reservoir, experimental core samples can reach 5.24% – 18.23%, higher matrix permeability, degree imbibition; (2) because thickness adsorbed layer, pores above sub-micron...
