一种新型勘探测井用非连续性可重复使用打捞矛
摘要：
本实用新型涉及一种勘探测井过程中使用的装置，尤其是一种新型勘探测井用非连续性可重复使用打捞矛。本设计的勘探测井用非连续性可重复使用打捞矛，极大的精简了机构，节省了成本，打捞过程变得非连续性，即打捞过程中觉得不合适的时候可以随时将打捞矛取出来，同时本设计提供了两种退打捞矛的方法，极大的保证了打捞矛的可重复使用，避免了资源的浪费，有利于更换成本的减少，设计使用性很强。有益效果：勘探测井用非连续性可重复使用打捞矛可以简化传统打捞矛的结构，采用一次性铸造完成，成本降低，多次重复使用，节省使用成本，实现非连续性打捞，有利于搞清井下工具状况，提供两种方法取出打捞矛，极大的保证了可重复使用性。
摘要（英）：

The utility model relates to a device used in the exploration well logging process, in particular to a novel discontinuous reusable fishing spear used for exploration well logging. According to the novel discontinuous reusable fishing spear used for exploration well logging, the mechanism is greatly simplified, cost is saved, the fishing process becomes discontinuous, namely the fishing spear can be taken out at any time in the fishing process when a user thinks that fishing is inappropriate, two methods for retreating the fishing spear are provided, it is ensured that the fishing spear is reusable, waste of resources is avoided, reduction of replacing cost is facilitated, and the design is high in practicability. The novel discontinuous reusable fishing spear used for exploration well logging has the advantages that the structure of a traditional fishing spear can be simplified, the fishing spear is cast in a one-off mode, cost is reduced, the fishing spear can be used repeatedly, using cost is saved, discontinuous fishing is achieved and beneficial for mastering conditions of downhole tools, and the two methods are provided for taking out the fishing spear, so that reusability is ensured well.
