尾管悬挂和回接固井异常工况分析及对策

尾管悬挂、回接固井在固井施工中出现的异常工况将直接影响固井后续施工作业质量和延长施工周期。因此如何避免尾管悬挂和回接固井在施工中异常复杂工况的产生,保证固井施工正常有序的完成,是尾管固完井施工成败的关键之一。对尾管悬挂、回接固井在施工过程中出现的几种异常工况进行了分析和研讨,找出产生异常工况的原因,从而提出合理有效的预防措施,避免固井施工中出现的异常工况。

Analysis and Countermeasure of Abnormal Working Conditions of Tail Pipe Suspension and Return Cementing

The abnormal working conditions of the liner suspension and the back-joint cementing in the cementing construction will directly affect the quality of the cementing follow-up construction and the extension of the construction period. Therefore, how to avoid the occurrence of abnormal and complicated working conditions in the construction of liner suspension and back-joint cementing is one of the key to the success or failure of the completion of the liner-solid completion. It is necessary to analyze and discuss some abnormal working conditions that occur during the construction of the liner and back-joint cementing, and find out the causes of the abnormal working conditions, so as to put forward reasonable and effective preventive measures to avoid the abnormal working conditions in the cementing construction.
