Influence of recovery model of coalbed methane wells after drainage interruption on coal fines migration in propped fractures

open access: yesMeikuang Anquan
In the drainage process of coalbed methane well, the interruption of drainage will induce a large amount of coal fines to stay in propped fractures, causing damage to the permeability of propped fractures. Based on the solid-liquid two-phase flow and gas-

Experimental Study on the Gas Flow Characteristics and Pressure Relief Gas Drainage Effect under Different Unloading Stress Paths

open access: yesGeofluids, 2020
Coal seam gas is a critical substance because it can be a source of a large quantity of clean energy as well as a dangerous source of risk. A pressure relief gas drainage is an effective and widely used method for coal seam gas recovery and gas disaster ...

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

open access: yesAdvanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...
