摘　　要：孤东油田年井下作业达到 180 0井次 ,落物、卡钻事故经常发生 ,井下打捞工作量很大 ,年打捞工作量达 2 0 0井次。普通滑块捞矛 ,结构简单 ,使用方便 ,打捞成功率高 ,深受修井技术人员的欢迎。但是当捞获的落物处于卡钻状态时 ,滑块捞矛无法进行脱手 ,往往使井下事故复杂化 ,给进一步处理造成困难 ,为此 ,研制了可丢手捞矛。目前现场应用 4 6井次 ,成功率 10 0 % ,效果良好。Down-hole operation reached 1,800 time a year in Dongying Oilfield. The accident often happened during down-hole operation such as dropping and sticking. The annual fishing operation is up to 200 times. A slipping spear is widely accepted for its simple structure, easy operation and highsuccess. But the dropping to be fished is at sticking condition, the slipping spear has not to bereleasable, thus resulting difficult operation or making even serious down-hole operation. Theeconomy lost is conceivable. The releasable spear has been developed and has gone through 46 practical applications with 100% successes.
