This paper presents a broadband frequency tunable and polarization reconfigurable circularly polarized (CP) antenna, using novel active electromagnetic band gap (EBG) structure. The EBG surface employs identical metallic rectangular patch arrays on both sides of thin substrate, but rotated by 90 ° from each other. bias circuits are also orthogonal for surface, enabling the reflection phases incident waves to be tuned independently in wide range. By placing wideband coplanar waveguide (CPW)...
A novel design for a beam-switching antenna using active cylindrical slot frequency selective surface (ACSFSS) is presented. The system composed of an omnidirectional monopole and the ACSFSS, which employs new technique switching arrays. ACSFSS made up 12 columns with 8 slots each, dividing cylinder by 30°. To steer beam diodes are set off on, so that radiation pattern determined number state columns. estimate general dimension FSS, equivalent metallic reflector introduced optimized, then...
Shale gas, as an environmentally friendly fossil energy resource, has gained significant commercial development and shows immense potential. However, accurately predicting shale gas production faces substantial challenges due to the complex law of decline, nonlinear non-stationary features in data, which greatly repair robustness current models time series. To address these improve accuracy forecasting, this paper introduces a novel innovative approach: hybrid proxy model that combines...
A major challenge in transient pressure analysis for shale gas wells is their complex flow behavior and fracturing parameters. While numerical simulations offer high accuracy, analytical models are attractive due to computational efficiency broad applicability. However, traditional often oversimplified, making it difficult capture the seepage system, three-dimensional fracture characteristics seldom considered. To address these limitations, this study presents a comprehensive hybrid model...

The obtained using deep-learning models where simulator...
CO2-enhanced gas recovery (EGR) has emerged as a promising method for improving hydrocarbon production and achieving carbon sequestration in offshore reservoirs. This study investigates the performance influencing factors of CO2-based displacement using long core experiments. Consolidated synthetic cores were prepared to replicate reservoir conditions, experiments conducted at formation pressure temperature evaluate effects permeability, injection pressure, CO2 concentration, length on...
The exploitation of tight oil faces significant challenges due to their low permeability, complex pore structures, and rapid production decline rates. Water-based enhanced recovery (EOR) methods hold great promise cost wellbore safety. However, effectiveness is significantly constrained by injectivity clay swelling. water huff-n-puff strategy has demonstrated success in the Tuha Oilfield achieving economic production. Nevertheless, deeper mechanistic understanding needed elucidate underlying...
Spontaneous imbibition is a critical mechanism for the development of water-wet fractured reservoirs. In order to improve ultimate oil recovery, it important understand change in situ saturation during spontaneous process. this study, experiments two ends open (TEO) are conducted using unconsolidated sand packs. The packs filled with quartz sands three different particle sizes respectively and fully oil-saturated. Nuclear magnetic resonance (NMR) T2 used monitor behind front. For porous...
During the depletion development of condensate gas reservoirs, when formation pressure drops below dew point pressure, oil and natural systems are in non-equilibrium state foggy retrograde condensation.
