摘要
高含硫高压气井钢丝打捞作业面临断落钢丝分布复杂,难以判断落鱼状态,打捞难度大;气井产量高,地层能量活跃,压井难度大;硫化氢含量高,对人生安全、设备安全防护要求高等难题。结合钢丝断落特征及具体井况分析,优化形成防硫电缆配合钢丝探测器组合、内捞矛组合的打捞工艺,满足了井内打捞的需求;通过无固相压井液直推法压井,配合吊罐压井、实时液面监测,满足了井内清洁、井控安全的要求;采用防硫材质作业设备,满足高压含硫气井的防护及井口安全。形成的综合性作业方案在YB121H井应用,成功解决了高压高含硫气井钢丝打捞的难题。
Fishing broken slickline in high H2 S and high pressure gas well has problems of the complicated distribution of broken slickline,being hard to estimate state of fish and to salvage,high production of gas well,high formation energy,being difficult to kill well,high H2 S content,and higher required standards of safety for both equipment and personnel. Techniques of combination of anti-H2 S wireline with slickline detector and combination of inner drags have been developed to meet the need of fishing broken slickline in well bore by considering the broken feature and down-hole conditions. Moreover,direct kill well with solid-free well control fluid,kill well in conjunction with tank,and monitoring on real time well,could satisfy the requirement of cleaning and safely controlling well. Anti-H2 S equipment has to be used for safety issue. Application of integrated procedure in well YB121 H solved the problem of fishing broken slickline in this high pressure high H2 S well successfully l.
