摘要
中原油田套管损坏的主要原因是现有套管强度不够,无法抵抗盐膏层段的巨大外挤力。针对这一问题,开发了一种特殊套管——TP130TT高抗挤厚壁套管。其强度高,能很好地抵抗盐膏层的巨大外挤力,各项性能指标达到了设计要求,经现场应用达到了预期的目的,取得了很好的效果,解决了中原油田盐膏层段套管强度不足的难题。
The main reason of casing failure in Zhongyuan oilfield is that casing strength is insufficient to resist the immense external force in salt interval. To solve this problem, a special casing - TP130TT high collapsing strength heavy casing has been developed. This casing has sufficient strength to resist the external force of salt interval. All performance indexes have met the requirement. The desired purpose has been achieved in field application, thus solved the problem of insufficient casing strength in salt formation of Zhongyuan oilfield.
