Description

Handle instrument that rope coring fisher drops

Technical Field

The utility model relates to a fishing tool, in particular to handle the instrument that wire line coring fisher drops.

Background

The wire line core drilling technology is an innovation technology on the traditional common drilling technology, and compared with the common drilling method, the wire line core drilling technology has the advantages of high rock core sampling rate, long service life of a drill bit, low labor intensity of workers, high production efficiency, low drilling cost and the like. When the drilling process is finished and the core tube is filled with the core, the whole set of drilling tool is not lifted, but the core tube is lifted out of the drill rod by using a fisher with a wire rope, and the core tube is thrown into the bottom of the hole from the drill rod after the core is taken out.

The superiority of the wire-line coring technique in the drilling process itself is increasing in the application of drilling. However, the requirement for operators is high, and especially when an accident occurs in a drilling hole, the serious result is caused by improper treatment. For example, in the process of wire-line core drilling, a wire rope on a fisher for fishing an inner pipe assembly by wire-line core is broken, so that the inner pipe falls off at the bottom of a hole and cannot be lifted, and generally, the fisher is taken out by lifting the whole drilling tool, so that the conditions of manpower and material consumption, damage to the wall of a drilling hole, repeated drilling accidents and the like are caused.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example 1

As shown in fig. 1, the utility model provides a handle instrument that rope coring fisher drops, including solid round steel 1, the diameter of solid round steel 1 is 2.4-2.6cm, the one end of solid round steel 1 is provided with bottom end 2, bottom end 2 is conical structure, thin reinforcing bar 3 has been welded in proper order on the outside surface of solid round steel 1, and use density to be 5cm interval spiral rebound arrangement apart from 2 looks intervals 6cm in bottom end, the length of thin reinforcing bar 3 is 7-8cm, the diameter is 0.5-0.6cm, 1 degree with solid round steel is 10 degrees, the other end of solid round steel 1 is provided with top end 4, and long 4cm, thick 1 cm's platykurtic structure, the inboard of top end 4 is provided with through-hole 5, and the perforation diameter is 0.8 cm.

Specifically, this product is that a solid round steel that is 2.4 ~ 2.6cm by the diameter is processed and is formed, and at the table body that solid round steel bottom 6cm height rises, according to certain interval proportion welding length be 7 ~ 8cm long, the thin reinforcing bar that the flare degree is about 10, and the thin reinforcing bar diameter is 0.5 ~ 0.6cm, and the welding thin reinforcing bar is upwards moved with the 5cm interval spiral of density and is arranged, and the total interval length of welding thin reinforcing bar is 45 cm. And the original steel with the length of 5cm at the bottom end of the solid round steel is polished into a conical shape, and plays a role in guiding in the process of lowering the orifice. The round steel is processed into a flat perforation with the length of 4cm and the thickness of 1cm at the top end of the solid round steel, the diameter of the perforation is about 0.8cm, and the perforation is used for penetrating and connecting a steel wire rope with the diameter of 0.62 cm.

The using method comprises the following steps: the product is mainly applied to the process of fishing the inner pipe assembly to be transferred or lifted in the process of wire line coring drilling, the phenomenon of fracture of a steel wire rope on a fisher occurs, and the inner pipe falls off in the treatment of drilling accidents that the bottom of a hole can not be lifted. When taking place such drilling accident, in order to avoid to promote destruction drilling pore wall and consume the resource that leads to the whole drilling tool, connect this product with new wire rope through the perforation and transfer to fisher off-position, start the rig and carry out low-speed drilling, fisher and the remaining wire rope downthehole of being connected with fisher can rotate along with the drilling tool, cause the wire rope that remains at fisher end can block in round steel and welded thin reinforcing bar mouth, along with the rotatory card that heals of drilling tool, promote this product at last, fisher can promote ground along with this product and rock core in the lump. Therefore, the accident handling cost is saved, the drilling efficiency is improved, and the risk is reduced.

The device is a tool specially used for processing the falling of the rope coring fisher, can solve the problem that the rope coring fisher can be taken out without lifting the whole drilling tool, saves manpower and material resources and avoids the repeated occurrence risk of drilling accidents.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
