Autor: ZHANG Hao, FU Chang, MAN Hongxia, CHEN Cheng, FANG Xinxin, LI Zongxing

Publikováno v: Dizhi lixue xuebao, Vol 28, Iss 4, Pp 550-560 (2022)

In oil and gas seismic exploration, when the seismic wave propagates in the earth medium, it will encounter obvious absorption and attenuation, resulting in the main frequency of the seismic signal shifting to the low-frequency end. The frequency ban

The factors influencing the enrichment of organic matters in the Carboniferous source rocks, Ounan depression, eastern Qaidam basin

Autor: SHI Hui, LI Zongxing, YANG Yuanyuan, PENG Bo, HU Junjie, FANG Xinxin, ZHANG Hao, WEI Xiaojie

Publikováno v: Dizhi lixue xuebao, Vol 28, Iss 2, Pp 203-216 (2022)

The Ounan depression is a favorable structural unit for the Carboniferous hydrocarbon migration and accumulation, which demonstrates certain exploration potential. However, the organic matter enrichment mechanism is still unclear, which results in th
