Near-surface velocity inversion and modeling method based on surface waves in petroleum exploration: a case study from Qaidam Basin, China

Autor: Xingrong Xu, Yancan Tian, Dunshi Wu, Junfa Xie, Zedan Wang, Tao Zhang

Publikováno v: Frontiers in Earth Science, Vol 12 (2024)

Surface waves are widely used in the study of underground structures at various scales because of their dispersion characteristics in layered media. Whether in natural seismology or engineering seismology, surface wave analysis methods have matured a

The key technology of 3D seismic data contiguous processing and its application: Taking the northern slope area of Zhahaquan in Qaidam Basin as an example

Autor: Yulian Zhao, Tao Zhang, Xinyuan Feng, Yue Ling, Xilin Wang, Junfa Xie

Publikováno v: Journal of Natural Gas Geoscience, Vol 8, Iss 5, Pp 363-375 (2023)

The surface conditions in the northern slope area of Zhahaquan in the Qaidam Basin are complex, and the underground is affected by tectonic extrusion movements, resulting in the development of faults and fractures. The existing six blocks of 3D seism

Automatic velocity picking with restricted weighted k-means clustering using prior information

Autor: Junfa Xie, Xingrong Xu, Yang Lan, Xiaoqian Shi, Yundong Yong, Dunshi Wu

Publikováno v: Frontiers in Earth Science, Vol 10 (2023)

Automatic picking of seismic velocity can be performed using k-means clustering. In simple k-means clustering, the number of clusters needs to be predetermined, while the picking result is affected by the initial value of each cluster center. In this

Application of Iterative Virtual Events Internal Multiple Suppression Technique: A Case of Southwest Depression Area of Tarim, China

Autor: Mingtu Xiao, Junfa Xie, Weihong Wang, Wenqing Liu, Jiaqing Sun, Baozhong Jin, Tao Zhang, Yuhe Zhao, Yihui Wang

Publikováno v: Applied Sciences, Vol 13, Iss 15, p 8832 (2023)

The seismic records in the Cambrian southwest depression of the Tarim Basin exhibit discrepancies when compared to the actual geological setting, which is caused by the presence of multiples. Despite the application of the Radon transform, multiple i

Effect of neutral pressure on the blue core in Ar helicon plasma under an inhomogeneous magnetic field

Autor: Chenwen WANG, Yang LIU, Meng SUN, Tianliang ZHANG, Junfa XIE, Qiang CHEN, Haibao ZHANG

Publikováno v: Plasma Science and Technology. 25:045403

The effect of neutral pressure on the blue core in Ar helicon plasma under an inhomogeneous magnetic field was investigated in this work. The neutral pressure was set to 0.08 Pa, 0.36 Pa, and 0.68 Pa. A Nikon camera, intensified charge-coupled device
