摘要:
 

打捞节流器时，芯杆在中间脱扣后，节流器上半部分易被捞出，下半部分芯杆、卡瓦、胶筒及防砂短节则留在井内，卡瓦散落于芯杆与油管内壁之间的缝隙里，打捞

效果差。环形强磁打捞器通过扶正机构与环形磁铁配合使用，实现了井下准确定位穿越芯杆的功能，且强磁随之下探进入芯杆与油管之间的缝隙并靠近卡瓦，实现了强磁对卡

瓦的近距离吸附。苏25419井采用环形强磁打捞器将脱落的三块卡瓦全部捞出，并用可退式卡瓦打捞器抓住芯杆成功打捞出残余节流器。环形强磁打捞器是打捞缝

隙里的小型卡瓦的有效工具。

Abstract:
 

When fishing the choke, after the core rod trips in the middle, the upper half of the

choke is easy to be fished out, and the core rod, slip, rubber barrel and sand control nipple in the lower half are left in the well. Slips are

scattered in the gap between the core rod and the inner wall of the tubing, resulting in poor fishing effect. Through the combination of centralizing

mechanism and annular magnet, the annular strong magnetic fishing device realizes the function of accurately positioning and passing through the

core rod underground, and the strong magnetic then probes down into the gap between the core rod and the oil pipe and close to the slip, realizing

the close adsorption of strong magnetic to the slip. In Well Su 25419, the annular strong magnetic fishing device was used to fish out all three

slips, and the retractable slip fishing device was used to grasp the core rod to successfully fish out the residual choke. Annular strong magnetic

fishing device is effective to fish small slips in the gap.
