Abstract
The utility model relates to a sandstone type uranium ore well logging gripper tube midway salvaging device, for effective processing of exploring tube well gripping accidents appearing the midway of sandstone type uranium ore field well logging process. In the utility model, an elongated slot with a diameter of 2cm and a length of 2-3m is opened along the pipe wall upward at the bottom of the inner tube, the upper end of the elongated slot is rasped into a smooth circular arc, a number eight iron wire with a length of 10cm is welded along the pipe wall at one end of the inner side opening at the lower end of the elongated slot, and the iron wire and the inner tube are in vertical shape. The utility model has novel design, simple structure, labor-saving and time-saving performance, economy and practicality, capability of using local materials, and capability of not damaging the steel wire and also not damaging the exploring tube and radioactive source in the salvaging process. After 3 years of experiments, the success ratio of the sandstone type uranium ore well logging gripper tube midway salvaging can reach 100%.
Description
One, technical field
The utility model relates to a kind of sandstone type U-ore well logging card and manages fishing device midway, is applicable to the effective processing that occurs inserting tube card well accident in the open-air well logging process of sandstone type U-ore midway.
Two, background technology
In the open-air well logging process of sandstone type U-ore, owing to falling piece, taking off reasons such as trousers, inserting tube card well accident usually occurs, mainly be to take to drag simply firmly in the past, maybe the inserting tube of Ka Jing can be pulled out, but often steel wire cable is broken, and easily cause inserting tube and damage even scrap, this kind method is simple, but weak point is that the time is long, efficient is low, and is serious to the equipment damage.
Three, the purpose of utility model
The purpose of this utility model is the present situation at prior art, provides a kind of sandstone type U-ore well logging card to manage fishing device midway, and it is simple, weak point consuming time, and inserting tube had no to damage.
The purpose of this utility model is achieved like this: it upwards opens a diameter 2cm in the core barrel bottom along tube wall, the elongated slot of long 2～3m, the upper end of elongated slot is rasped to smooth circular arc, at No. 8 iron wires of inboard opening part one end in the lower end of elongated slot along tube wall welding one long 10cm, iron wire becomes vertical configuration with core barrel.
The utility model sandstone type U-ore well logging card is managed fishing device midway, and modern design is simple for structure, time saving and energy saving, can gather materials on the spot, and is economical and practical, in the salvaging process, can not cause damage to steel wire cable, also can not damage inserting tube and radioactive source.Through the experiment more than 3 years, the success rate that the utility model is salvaged at sandstone type U-ore well logging card pipe midway reaches 100%.
Four, description of drawings
Accompanying drawing 1 is managed the structure chart of fishing device midway for the utility model sandstone type U-ore well logging card.
Wherein: 1-----core barrel, 2----elongated slot, 3----iron wire.
Five, the specific embodiment
With reference to accompanying drawing, the utility model sandstone type U-ore well logging card is managed fishing device midway, it upwards opens a diameter 2cm in core barrel (1) bottom along tube wall, the elongated slot (2) of long 2～3m, the upper end of elongated slot (2) is rasped to smooth circular arc, at No. 8 iron wires (3) of inboard opening part one end in the lower end of elongated slot (2) along tube wall welding one long 10cm, iron wire (3) becomes plumbness with core barrel (1).Concrete salvage process: earlier cable is put into by core barrel bottom end opening place, and guarantee that guiding principle silk cable is enclosed in the pipe by No. 8 iron wires, make it to skid off outside the pipe, then steel wire cable is manually strained, along steel wire cable that the core barrel of belt length groove is following to always the inserting tube place that is blocked, when feeling that steel wire cable is toward downslide, allow drilling rod continue descending 3～5m again, then just can be along with the inserting tube that blocked that the lifting of drilling rod will be ensconced in the core barrel is salvaged smoothly.
Claims (1)
1. a sandstone type U-ore well logging card is managed fishing device midway, its feature in: it upwards opens a diameter 2cm in core barrel (1) bottom along tube wall, the elongated slot (2) of long 2～3m, the upper end of elongated slot (2) is rasped to smooth circular arc, at No. 8 iron wires (3) of inboard opening part one end in the lower end of elongated slot (2) along tube wall welding one long 10cm, iron wire (3) becomes vertical configuration with core barrel (1).
