With the extensive application of sensor technology in scientific ocean research, resource exploration, underwater engineering construction, and other fields, target positioning has become an important support for field. This paper proposes a robust algorithm that combines disadvantages distributed estimation particle swarm optimization, which can solve large localization error problem caused by uncertainties acoustic communication sampling processes. Considering presence ranging anomalies...
There is a growing focus on the development of advanced materials to enhance energy efficiency in space heating and cooling, which accounts for 13% annual consumption global energy. Radiative cooling work wavelength span middle-to-far-infrared light, especially at 8–13 μm, effective heat dissipation. However, their fixed emissivity results unpleasant overcooling consumes excessive winter. Adaptive can change response temperature fluctuations, solving problem overcooling. absorption too much...

The plastic deformation and interface micro annulus of oil-well cement during acid fracturing are key reasons for the failure wellbore seal sustained casing pressure. However, most existing research ignores influence cooling effect fracturing, owing to which, design conditions in theoretical analysis may be inconsistent with those actual wellbore, calculation results biased. In this study, a novel elastoplastic mechanical model sheath was established. This can analyze yield state under...
Abstract Patterning polymeric materials with controllable microstructures can meet diversified requirements and realize promising applications. Exploring micro‐/nano‐pattern methodology offers possibilities for future techniques, however, the self‐organized growth of has some limitations development direct noncontact patterning processes is still challenging. In this work, study presents a facile strategy endowing polymers spatially regulated by photo‐printing, which incorporates both...
The precise evaluation of micro-crack sizes and locations is crucial for the safe operation structures. Traditional detection techniques, however, suffer from low spatial resolution, making it difficult to accurately locate micrometer-scale cracks. A method experimental study were proposed in this paper identifying locating micro-cracks using optical fiber strain sensing based on OFDR address issue. feasibility was verified by combination a polyimide-coated (PISOF) tight sheath (TSSOF)....
The cement sheath-formation interface is a weak link in wellbore isolation systems, which prone to the failure of sealing integrity during fracturing, affecting fracturing effect, and safety. In this study, we establish new model evaluate mode crack propagation interface. Using proposed model, predicted direction length zigzag cracks caused by stress, load, stress intensity factor (SIF) under temperature pressure shale oil well X eastern China field. prediction results were consistent with...
Gas prevention and control have always been the focus of coal mine safety. The pore structure characteristics gas adsorption seams are key factors affecting diffusion in seams. Lvjiatuo Mine has a high content when it enters deep mining. In order to clarify influence pore-fracture main research area on seam diffusion, study differences ability different seams, low-temperature nitrogen (LT-N2GA), high-pressure mercury intrusion (MIP) computerized tomography (μ-CT) were used as...

Carbon capture and storage (CCS) technology has become one of the most cost‐effective promising ways to achieve global climate change mitigation goals. The CO 2 capacity in depleted oil gas reservoirs is currently safest economical option. long‐term sealing cement–formation interface wells (CSW) essential avoid leakage. filter cake easily affects interfacial ability, which a thin impermeable layer formed by drilling fluid residue or solid particles remaining on borehole wall due permeable...
Summary Ensuring the sealing integrity of cement sheaths used for shale gas wells during hydraulic fracturing processes has become a major challenge. The sustained casing pressure, strong temperature difference stress, and cyclic loading unloading affect safe long-term production wells.
