Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids
Advanced Functional Materials, EarlyView.This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Analysis on Erosion Wear Laws of High Pressure Manifold
Shiyou jixie, 2018 In view of the problem that the inner wall of the high-pressure manifold is damaged by erosion during the fracturing operation, the erosive wear rate and the erosion dispersion distribution of the inner wall of the high-pressure manifold are studied ...

Continuous Sand Transport Unit for Fracturing in Shale Gas Development
Shiyou jixie, 2016 Given large displacement and high sand ratio in shale gas recovery,a large amount of sand and fast sanding at 3~8 m3/min are required.The sanding mode in conventional fracturing is inapplicable for its low transport efficiency and large area occupation ...

Effect of Cementing Quality on Casing Failure in Horizontal Section of Shale Gas Well
Shiyou jixie, 2019 The casing for shale gas well is subject to complicate forces. The inferior cementing quality will easily cause large stress concentration on the casing, which will lead to deformation failure.
