Study on Damage Mechanism of Waterflooding Development in Weizhou 11‐4N Low‐Permeability Oilfield
Geofluids, Volume 2023, Issue 1, 2023., 2023 Weizhou 11‐4N oilfield is a medium‐low‐porosity and low‐permeability reservoir. The oilfield was initially developed by edge and bottom water energy and then transferred to water injection development. Affected by poor physical properties and heterogeneity of the reservoir, the oilfield appeared in the process of water injection development.

Characteristics and contributing factors of major coal bursts in longwall mines
Energy Science &Engineering, Volume 10, Issue 4, Page 1314-1327, April 2022., 2022 1. Fifty‐four major coal bursts that caused serious consequences are collected. 2. Features and contributing factors of coal bursts are quantitatively analyzed. 3. Mining environments with high burst risk are identified. Abstract Coal burst has become one of the most serious hazards in longwall coal mines of many countries, and extensive studies have ...

Earth and Space Science, Volume 8, Issue 6, June 2021., 2021 Abstract The 2020 Mw 6.5 Monte Cristo earthquake occurred in the northeastern Mina deflection of the central Walker Lane Belt (WLB) in Nevada, USA. The Mina deflection represents a typical stepover zone that transfers the dextral slip in the northern Eastern California Shear Zone onto the dextral faults in the central WLB.

Geofluids, Volume 2021, Issue 1, 2021., 2021 This research is aimed at investigating the influence of the coal height ratio on the mechanical properties and damage behavior of rock‐coal‐rock combined samples (RCRCS) under coupled static and dynamic loads. For this purpose, a uniaxial cyclic dynamic loading experiment with four different coal height ratios of RCRCS was conducted.

Dizhen xuebao, 2021 利用2014年10月至2019年9月期间欧空局Sentinel-1卫星采集的合成孔径雷达数据分析了2014年2月12日新疆于田MS7.3地震的震后形变场。结果表明，此次地震造成了南硝尔库勒断裂上明显的震后形变，首次从地震形变场的角度验证了此次地震的发震构造为NE向的左旋走滑断裂，而非部分研究所认为的近NS向断裂。由合成孔径雷达干涉测量得到的多年平均速率图显示主震的西侧仅出现了少量震后余滑且仍为强闭锁区，这意味着2008年和2014年于田两次MS7.3地震之间的区域仍存在发生强震的风险 ...

A Multifeature Complementary Attention Mechanism for Image Topic Representation in Social Networks
Scientific Programming, Volume 2021, Issue 1, 2021., 2021 Image topic representation in social networks is vital for people to get significant and valuable content. However, this task is difficult and challenging due to the complexity of image features. This paper proposes a multifeature complementary attention mechanism for image topic representation named CATR.
