Summary The identification of the fracture barrier is important for optimizing horizontal-well drilling, hydraulic fracturing, and protecting fresh aquifer from contamination. word “brittleness” has been a prevalent descriptor in unconventional-shale-reservoir characterization, but there no universal agreement regarding its definition. Here, new definition mineralogical brittleness proposed verified with two independent methods defining brittleness. Formation higher considered as good...
Abstract Sustained annular pressure caused by tubing leakage seriously threatens the safe production of deep gas wells. Therefore, it is necessary to fully understand characteristics sustained and find potential methods reduce risk. However, most models are about thermal expansion cement integrity failure. this paper establishes a model based on energy conservation law, pressure–volume–temperature (PVT) properties, volume consistency study leakage. The results indicate that in tubing-casing...
Abstract Leakage is one of the most serious challenges for safe production high‐pressure gas wells its high risks, including abnormal annular pressure, natural accumulation, and environment pollution, but available methods can hardly accurately measure leakage type depth, which are key parameters rigless repair risk assessment. Therefore, this paper proposes a method to based on characteristics, combines qualitative quantitative measurement together. Qualitative considers tubing liquid...
The bonding surface structure generated by the repair of concrete structures has been paid more attention as a weak point. effects old age, interface roughness, and freeze-thawing (F-T) attack on adhesive are comprehensively investigated. In this study, six kinds roughness five different age designed. interfacial property is mainly evaluated splitting tensile strength (fts). Fractal analysis was used to characterize using laser scanning data. general, fts increased with increasing value...
Real-time detection of Remote Sensing Imagery (RSI) with a wide background and small targets is challenging in various fields. Multimodal data fusion enhancing CNNs Transformers can improve performance. The approach combines complementary information from different modalities leverages CNNs' feature extraction capabilities. capture global learn sequence dependency without requiring large samples. goal to achieve accurate efficient target applications such as fire detection, military...
Halophilic fungi have evolved unique osmoadaptive strategies, enabling them to thrive in hypersaline habitats. Here, we conduct morphological and transcriptomic response of endophytic fungus (Aspergillus montevidensis ZYD4) both the presence absence salt stress. Under stress, colony morphology A. ZYD4 changed drastically exhibited decreased pigmentation. Extensive conidiophores development was observed under stress; rarely developed yellow cleistothecium formation inhibited, while glycerol...
Summary Pulse hydraulic fracturing technology can greatly improve the effect of fracture propagation in rock and form complex networks reservoirs. The interaction mechanism between fractures pre-existing under pulse pressure is unclear. induced laws on direction different frequencies pressures are revealed this work. We have carried out traditional (THF) tests with rock-like specimens. compared two tests. Acoustic emission (AE) characteristics during analyzed. results show that specimen...
The sustained annular pressure caused by channeling threatens the casing safety significantly. Cement mantle composite permeability and one-dimension unstable seepage were used to describe of high gas based on analysis structure cement containing micro-fractures process gas. According mass conservation law volume accordance principle, a model was built predict analyze rising when invades into trapped annulus, then this study impacts different factors pressure. can be divided rapid stage...
