打捞器

由于侧钻井、水平井特殊井身结构限制，常规的小件落物打捞器打捞成功率低。

Because the limit of special casing program of sidetracking well and horizontal well , the fishing success ratio of conventional little junk fisher is low .

针对电潜泵在起、下泵作业过程中电缆卡子落井的问题，研制了电缆卡子打捞器。

To solve the problem of cable grip dropping down the borehole during the running and pulling of electric submersible pump ( ESP ), the cable grip fisher is developed .

为解决上述问题，研制开发出开放式开窗捞筒打捞器。该打捞器由上接箍、窗舌、筒身、导向槽及引鞋组成。

The overshot is comprised of upper collar , tongue , body , guiding groove and fishing guide .

整套钻具包括：钻具总成、打捞器、钻杆、绞车、提引器、夹持器及自由钳等部件。

All the tools include principal of the drill tools , overshot assembly , drill rods , holding dog , circle wrench etc.

打捞器里面装满了驴耳贝、竖琴贝、河贝子，特别又打到了我今天才看见的最好看的糙鱼，我们又打了一些海参，产珍珠的牡蛎和一打左右的小鳖，这些都打来作为船上的食用品。

Our dragnet was filled with Midas abalone , harp shells , obelisk snails , and especially the finest hammer shells I had seen to that day . We also gathered in a few sea cucumbers , some pearl oysters , and a dozen small turtles that we saved for the ship 's pantry .
