Analysis on Influential Factors of Casing Stress Based on Fracture Induced Stress Field
Shiyou jixie, 2023 The staged fracturing of horizontal well creates artificial fractures, and the resulting fracture induced stress field affects the distribution of casing stress.In order to identify the influential factors of casing stress under the action of fracture ...

Mechanisms and controlling factors of casing deformation in horizontal wells of coal-bearing shale gas in continental–marginal marine transition zones [PDF]
AIP AdvancesThis study investigates recurrent casing deformation in the transitional marine–terrestrial shale gas reservoirs of the Ordos Basin, where complex sedimentary structural features intensify integrity risks during multistage hydraulic fracturing.

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

The Eect of Mechanical Loading on the Frequency of an Oscillator Circuit [PDF]
, 2009 We investigate the effect of mechanical strain on the frequency of an electronic oscillator embedded in an integrated circuit. This analysis is aimed at explaining a 1% inaccuracy in the oscillator frequency under test conditions prescribed by a leading ...
