通过对塔里木油田套管粘扣原因进行调查研究和失效分析,认为套管粘扣原因既与其本身抗粘扣性能差有关,也与使用操作不当有关。油田采购的套管抗粘扣性能差与订货标准没有严格要求有关,使用操作不规范导致大量套管粘扣与没有切实可行的套管操作规范,或者操作人员没有严格执行操作规程有关。要从根本上解决套管粘扣问题,首先应当对套管粘扣原因进行失效分析和研究,找出粘扣原因,依据失效分析和研究成果制定严格的订货技术标准和操作规程,并采取一定的措施落实订货技术标准和操作规程。
Based on the investigation and failure analysis of the reasons for the sticking of casing in Tarim Oilfield, it is considered that the reason of casing sticking is not only related to the poor performance of its own anti-sticking, but also to the improper operation. Oilfield procurement of anti-tripping performance of the casing is poor and there is no strict requirements on the order, the use of non-standard operation leads to a large number of casing with non-trimming and no practical code of casing operation, or operators do not strictly implement the operating procedures. To fundamentally solve the problem of casing fastening, first of all should be on the cause of casing tripping failure analysis and research to find out the reasons for sticky buckle, based on failure analysis and research results to develop stringent ordering technical standards and practices, and to take certain Measures to implement the order technical standards and operating procedures.
