濮城油田是一个埋藏深、含油层系多、油藏类型多、非均质性严重的断块油气田;特别是盐层发育活跃,目前濮城油田主要有沙一盐、沙二下盐、文九盐等三套盐层。针对这一特性,2002年以来我们在钻井施工中应用TP130TT×16.9高强度抗挤特殊扣套管,在减少油水井套管的损坏,延长套管寿命方面取得了良好的效果。
Pucheng Oilfield is a deep-buried, oil-bearing multi-type, multi-reservoir type, serious heterogeneity fault block oil and gas fields; in particular the active development of salt, Pucheng Oilfield is currently the main salt, sand two under salt, Man Kowloon salt three sets of salt. In response to this feature, since 2002, we applied TP130TT × 16.9 high-strength anti-extrusion special buckling casing in drilling construction, which has achieved good results in reducing casing damage and extending casing life.
