摘要
以东濮凹陷WZ油田历年井况大调查套管损坏资料为依据,在对出砂油井套管损坏形态、层位与射孔状况、岩石性质等因素进行综合分析基础上,对疏松砂岩出砂、上覆岩层坍塌等主要方面导致的套管受力变形进行研究,为探讨及防治措施提供依据。
Sand production is the main causes of casing damage based on well status survey in WZ oilfield of Dongpu depression over the years. The paper presented the shape and horizon of casing damage, and analyzed the perforation status and lithology in sand production oil well. The casing deformation caused by sand production of unconsolidated sandstones and caving of the overburden is studied .It provides a basis for preventing casing damage in unconsolidated sandstones.
