普光气田套管变形规律研究
|
摘要
介绍了普光气田套管变形监测情况及套管变形结果,分析了套管变形与地层岩性、盐层厚度、固井质量、套管厚度、地震以及时间延长等之间的关系。研究结果表明,2008年"5.12"大地震诱发并加速了盐岩层的蠕变,造成套管变形,随着时间的延长,变形情况越来越严重。
The detection and outcome of casing deformation in Puguang Gas Field were introduced,the relationship between the casing deformation,lithological property,salt-bed thickness,cementation quality,casing wall thickness,earthquake and time delay was analyzed.The result shows that the earthquake caused in May 12,2008,expedites salt-bed creep and induces the casing deformation,the casing deformation would be more serious with the time being.
