Compact fishing apparatus

Abstract

The invention provides a single entry, one trip, compact drill pipe fishing apparatus (20), it consists of a cylindrical housing (21), supporting the inner tools and mechanisms; a rotatable spindle (23) is penetrating its top cap (24), and driving the inner mechanisms. The cap (24) is rotating the housing (21), while moving downward, there is two sets of keys (32), distributed through bores made horizontally inside the housing (21) body, then, syringe type lubricant tools are installed through bores made in the housing (21) body, then, in the bottom part of the housing (21), an inner cylindrical cutting block (40) is installed, with four cutting outlets bores, made via the housing (21) body, finally three cameras are installed. The fishing operation starts by cutting two sets of holes in the drill pipe (fish) (22), lubricating the holes, engaging the keys, pushing the fish right / left, and up / down via the engaged keys (32), to penetrate the oil, and pulling up the fish (22).

Description

technical field [0001] The present invention relates to a device that picks up a stuck tube, releases it from the stuck place, and then withdraws it from the surface. Background technique [0002] The lifting procedure of equipment or other objects due to failure or jamming by the drilling team using special tools or devices to remove equipment or other objects from a hole, such as a drill string (drill pipe) return, is quite expensive, Time-wasting, complex and dangerous processes, especially working in an unfriendly and high-stress environment, mainly due to differential pressure sticking. The original patent for lifting technology in the oilfield was Patent 2,972,380, issued by A.G. Bodine in 1961, which introduced the concept of resonance, which is primarily a reactance that effectively eliminates mechanical resistance, and thus can lead to effective sound wave transmission. The pressure detection technique using the three-point tool is used to find a specific high poi...

AI Technical Summary

Problems solved by technology

Vibration technology can achieve 90% success rate, but it is still limited by the length of the drill pipe, from 10 to 220 meters, which means it is limited by the depth of the well

[0003] Therefore, to release the stuck drill pipe, it is not necessarily successful at the first time. In many different steps, various forms of procedures and tools need to be used until the release is successful; this approach is considered Quite expensive when it comes to time and money, even though some devices claim to be a single tool (comprehensive tool) to perform all the steps or procedures for releasing the stuck drill pipe in a single entry hole (single procedure operation ) to operate, just like in US Patent No.: US2,830,663; US2,090,616; US1,968,282; and US5,810,410, but none of the above-mentioned patents can achieve: a-lubrication; b-vibration; c-pull up the drill pipe with a single operation procedure
