Abstract
- In recent years, Shuangwang well in Weinan has accumulated a large number of accurate and reliable fluid observation data, but the data has not been systematically cleaned and analyzed. We systematically sorted the digital observation data of underground fluid in Shuangwang well from the date of digital observation start to the end of 2021 (1 June 2007 to 31 December 2021). Taking the interference and pre-earthquake anomaly observation data of water level and water temperature observation of Shuangwang well as the research object, the changes of digital observation data were analyzed, and the shape of the curve under the interference and pre-earthquake anomaly was analyzed. Analysis was carried out from the aspects of trend change characteristics, characters of earth tide, coseismic variations, preseismic anomalies and typical interference anomalies, and the change characteristics of the underground fluid data of Shuangwang well were researched, and the information reflected in the observational data were summarized and applied. It will provide scientific basis for the study of water temperature and water level anomalies and earthquake prediction in Weinan and its surrounding areas in the future.
