Due to the development of printing materials, light-cured 3D is playing an increasingly important role in industrial and consumer markets for prototype manufacturing conceptual design due its advantages high-precision high-surface finish. Despite widespread use, it still difficult achieve requirements large volume, high resolution, speed. Currently, traditional technologies based on stereolithography, such as regular DLP SLA, can no longer meet processing size rate. This paper introduces a...
Abstract Electrical Submersible Pumps (ESPs) are widely used in the oil and gas industry to provide external energy producing wells when natural drive of reservoir is insufficient. However, ESPs susceptible repetitive impact wear caused by solid particles, which affect pump performance run life. Predicting degradation crucial estimate workability overall life an ESP. Sand erosion testing was carried out at Tulsa University Artificial Lift Projects (TUALP) on two multi-stage mixed flow ESPs....
With the rapid development of lightweight and environmentally friendly building materials, foamed concrete has been widely adopted as a novel material for filling foundation applications. However, its bearing capacity under localized loading conditions requires further investigation. This study focuses on silt-based with 30% silt content. A series unconfined compression tests triaxial shear were conducted to determine key mechanical properties. Large-scale indoor model then carried out...
Mullite whiskers were prepared from Si powders in molten Al2(SO4)3-Na2SO4 mixture salts with different Al/Si molar ratio (R) of raw materials. The resulting mullite whiskers, had been investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and infrared spectroscopy analysis (FT-IR). phase was obtained when the temperature reached at 850 °C. SEM EDS results revealed that two kinds microstructures formed final product, Al-rich...
Application of sandstone in cement-stabilized macadam (CSM) is an effective way to utilize sandstone. To determine the feasibility using as a CSM aggregate, series experimental investigations, such unconfined compressive strength (UCS) tests, Brazilian splitting tests and freeze-thaw cycle were conducted on (SCSM). Three mixed variables, covering cement content, aggregate type curing period, set influence factors. The testing results indicated that UCS, indirect tensile (ITS) frost...
This study addresses the use of preplaced casting method in lightweight aggregate concrete (LC) to provide a new perspective solve segregation. In (PLC), aggregates are cast into formworks and then fresh grout is injected fill voids. PLC conventional (CLC) with three different mixtures compared observe degree The properties CLC characterized by means cubic axial compression, splitting tension flexural tests, static modulus elasticity, drying shrinkage measurements. Results show that...
Abstract Fiber reinforced concrete beams are a popular research topic because of the improvement in performance with fibers. PVA‐FRC GFRP have better mechanical properties than those ordinary when considering combination multidirectional material properties. This article presents results an experimental study on flexural behavior beams. Seven were tested. The test variables included PVA fiber content and diameter. indicated that existence bars is effective for enhancing load‐carrying...
Abstract The paper summarized an experimental and theoretical study of the collapse resistant ability solid expandable tubular (SET)after expansion, formula used to calculate strength casing was modified make it adaptable tubular. One key limiting factor in its application open hole well replace is post-expanded mechanical properties. after expansion significantly compromised as result comprehensive influence by change factors like ovality, eccentricity residual stress. In view these...
Abstract Solid expandable tubular was widely used for casing patching and proved to be cost effective, however, when the damaged area of is exactly located below position previously applied by this technology, conventional may not choice do job since could positioned smoothly due loss wellbore size caused installed tubular. The paper discussed an innovative design meet challenge. Basically new involves putting expansion tool outside tubular, as a result ratio maximized without launcher pass...
Abstract The introduction of solid expandable tubular has been successful in the oil and gas industry, normally nitrile-butadiene rubber was vulcanized outside order to seal off annulus between wellbore, may fail at about 400K temperature, making incapable while applied high-temperature wells. To solve this problem, two kinds materials aimed replacing were considered, one is copper which could be welded upon tubular, other steel protruding part SET body can obtained through machining...
This article selects relatively common residential area as the prototype and uses finite element analysis software ANSYS/LS-DYNA to establish a framework simplify model. Four scene measured vibration velocity are loaded on structural The dynamic response under four different peaks blasting is simulated, simulation results summarized.
