The influence of Wenchuan Earthquake on Puguang Gas Field development

Ge Hongkui,Shen Chen,Song Lili,Wang Xiaoqiong

Strategic Study of CAE 2010, Volume 12, Issue 10,   Pages 103-107

Abstract:

Well casings of Puguang Gas Field took place abnormal deformation beforeand seismic load analysis, it was concluded that Wenchuan Earthquake was an important factor to the deformationSeismic load caused static stress change,dynamic load, fault slip, inconsistent deformation between stratums, salt/gypsum creep speedup and casing deformation.The analysis showed that not only the stress size affected the deformation, but also the stress change
