The complex fracture network in unconventional oil and gas reservoirs is the main channel for fluid flow, effective prediction of permeability basis further accurate assessment productivity. On traditional parallel-plate cube law, we introduce tortuosity fractal dimension DTf to characterize fractures. Then, combined with theory, a model derived tortuous discrete (DFN). A pixel probability decomposition algorithm used generate ten random DFNs that conform scale relationship, effectiveness...
Abstract The effect of crack angle on energy evolution during sandstone failure subjected to true triaxial cyclic loading and unloading is great concern. However, the consumed in initiation compaction process generally referred dissipated energy, which inaccurate. To reveal law breaking sandstone, a complex test carried out precast angled samples by employing system. area integral methodology exploited evaluate total density, elastic plastic density rock different angles. variations these...
Understanding the spontaneous imbibition in natural fracture with heterogeneous wettability is crucial for predicting and mitigating impacts of unstable displacement on unconventional recovery. In this paper, structured mesh model reconstructed based micro-computed tomography (micro-CT) image naturally fractured tight sandstone. The mineralogy map-based modeling method heterogeneous-wetting developed by combining thin section images, X-ray diffraction (XRD) analysis, multiple point...
Coalbed methane (CBM) is an unconventional energy source. Its productivity mainly controlled by the fracture network of coal seam. Therefore, key to accurately evaluate CBM simulate complex in reservoir. In comparison, many studies about simulation networks are based on assumptions that smooth, they do not accord with actual fracture. Here, a stochastic rough (SRFN), which closer real network, established pixel probability decomposition method. The relationship between fractal geometric...
The disturbance due to coal mining causes the surrounding rock undergo a complex process of stress changes during which axial pressure and confining usually change accordingly at same time. Existing studies generally investigated this from static perspective, was not rigorous. mechanical characterization is very important understand failure mass safety disturbance. Based on theoretical analysis, we conducted loading radial unloading tests cracked sandstone, combined with ultrasonic testing...
Abstract In underground engineering such as mining and tunnel excavation, the rock mass is often subjected to repeated loading unloading stress environments. Herein, true triaxial cyclic tests are carried out on fine sandstone medium‐fine specimens with cracks of different angles. The test results show that mechanical properties samples obvious differences, crack angle has a significant effect specimen. During experimentation, expansion phenomenon more than sandstone, its brittleness also...
Using fresh core samples, we have determined the origin and formation process of Eocene lacustrine dolomites in Tibetan Plateau through petrological, mineralogical, geochemical analyses. Dolomitic rocks were collected from upper member Niubao Formation Lunpola Basin, consisting dolomitic mudstone, argillaceous dolomite, dolomite-bearing mud-bearing dolomite. These are dominated by aphanotopic microcrystalline dolomites, with minor amounts euhedral or subhedral powder- fine-crystalline...
