油田井下打捞作业及其工具改进分析

Analysis on downhole fishing operation and its tool improvement in oilfields

油田井下作业存在明显的局限性,主要因素在于所研制的专业工具功能存在片面性。此外,井下管道由于在恶劣环境下长期得不到正确保养,出现管体开裂、松脱等情况,本文针对上两种因素进行详细的分析,对井下打捞技术和工具的改良提出了相应的策略。

The specialty tool developed for the downhole operations in oilfields has the disadvantage of one-sidedness,which causes the obvious limitation existed in downhole operations.In addition,due to the lack of proper maintenance in the long-term time in the bad environment,the conditions such as pipe body cracking,loosing and sliding would occur in downhole pipeline.So,this paper focuses on the detailed analysis on the two above-mentioned conditions and puts forward the corresponding strategies to improve downhole fishing technology and its tools.
