摘要
通过对一起地热深水井常见事故类型:填砾或投放止水泥球、固井石子发生的蓬堵事故原因的分析,提出了正冲、反吸排渣处理蓬堵事故的工艺及预防措施。并简要介绍了处理该类事故所需的机具及工艺。
By the analysis on the plugging accident in a deep geothermal well caused by gravel-filling or water-stopping mud ball and cementing pebble throwing,positive impact and reverse suction technology were put forward.The paper introduced the equipment and treatment technology for this kind of accident.
