Abstract
The utility model discloses an underground debris fishing cylinder used in oil industry, suitable for workover operation of an oil or water well, which comprises an upper joint and an outer cylinder. A fishing mechanism is connected with the upper joint and threaded into the outer cylinder to form a combination and can relatively be moved against the outer cylinder; a screwed cutting piece is arranged at the center of the combination in order to not only be drilled into the accumulated debris for catching the debris, but also prevent the debris from dropping. The utility model overcomes the disadvantages of the prior art of low debris fishing efficiency and increases the underground debris fishing efficiency and decreases the production cost. The utility model has the advantages of having simple operation, having high fishing efficiency, reducing operating time and reducing production cost.
Description
Technical field
The utility model belongs to the workover treatment instrument of petroleum industry, and particularly a kind of down-hole fishing socket that minces is applicable to the workover treatment engineering of oil-water well.
Background technology
At present in the workover treatment process of petroleum industry, often need mince and salvage fritters such as the cable onal of the well that falls, strain relief clamp, broken rubber.Existing Refloatation method is that cover mills or milling is handled.Adopt the way of milling, mince and generally follow junk mill and together rotate, junk mill milling speed is slow, and efficient is low, and the engineering time is long, and cost greatly.The method that adopts cover to mill though casing section mill can be introduced in the casing section mill mincing, can't be salvaged pit shaft with mincing, often cause junk to repeat cover and mill.And cover suppresses when milling that to jump phenomenon more serious, and is big to the drilling tool damage.Because fishing success ratio is low, the anti-dipper that circulates of less employing carries out the salvaging of similar junk.
Summary of the invention
The purpose of this utility model is to manufacture and design a kind of down-hole fishing socket that minces, and overcomes defective of the prior art, improves the salvaging efficient of above-mentioned junk, reduces production costs.
The present technique solution can reach above-mentioned purpose: a kind of down-hole fishing socket that minces, comprise top connection and urceolus, and fish for mechanism and be connected with top connection, be set in the urceolus.
The utility model is compared with original fishing tool that minces has following advantage: with urceolus with fish for mechanism's applied in any combination, each other can relative motion, core bar increases the spiral section therein, both can pierce mincing of accumulation, catch junk, can guarantee that again the junk of catching can not deviate from once more.The spiral section of center-pole bottom welding and the grinding layer of shop weldering pierce mincing of accumulation as spiral bit.Forcing minces upwards enters in the urceolus along the spiral section.On carry drilling tool and urceolus is moved down wrap the spiral section, be blocked in the urceolus introducing above the mincing of spiral section, realize efficient salvaging to mincing.This tool operation is simple, salvages the efficient height, avoids repeating in a large number work, reduces the engineering time, has reduced operating cost.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: top connection 1, center-pole 2, gland 3, shelves ring 4, urceolus 5, spiral section 6, grinding layer 7.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail: referring to accompanying drawing, a kind of down-hole fishing socket that minces comprises top connection 1 and urceolus 5, fishes for mechanism and is connected with top connection 1, is set in the urceolus 5.Fish for mechanism and comprise center-pole 2, shelves ring 4 and spiral section 6, the lower end of center-pole 2 is coniform.At the bottom of center-pole 2 cylindrical spiral section 6 is set, cylindrical is provided with shelves ring 4 in the middle, is used to hitch urceolus 5.Thus urceolus 5 can shelves encircle 4 and top connection 1 between move freely and rotate.The top cover of urceolus 5 is glands 3, and the top of urceolus 5 cylindrical shells is connected with gland 3.The bottom of fishing for mechanism and urceolus 5 is equipped with grinding layer 7.During on-the-spot the use, this instrument is brought the down-hole into by the drilling tool connection and is in position shown in the accompanying drawing.Urceolus 5 is in the position of shelves ring 4.Behind urceolus 5 contact junks, no longer move down.2 continuation of center-pole also contact junk up to center-pole 2 downwards, and ground shows that the pressure of the drill increases, and show instrument contact junk.The rotation drilling tool, center-pole 2 rotates thereupon.Because sharply then urceolus 5 was not blocked by junk and rotates with drilling tool the grinding layer of shop, urceolus 5 bottoms weldering in 70 minutes.Center-pole 2 pierces the junk of accumulation downwards under the effect of the pressure of the drill, and forces junk along the spiral 6 up inner chambers that progress into urceolus 5 of cutting into slices.Center-pole 2 is constantly descending to withstand on the upper surface of gland 3 up to top connection 1, and ground shows that the pressure of the drill increases suddenly, represents that a salvaging process finishes.Stop the rotation drilling tool and on carry, in the center-pole 2 indentation urceolus 5 and stop that the junk that enters urceolus 5 deviates from.On carry the instrument certain distance after, can repeat aforesaid operations 2-3 time, salvage pit shaft with mincing in the pit shaft as much as possible.After instrument trips out, only need top connection 1 is dismantled, center-pole 2 just can be extracted out from urceolus, is convenient to remove the junk on stockpiling in urceolus 5 of salvaging and the center-pole 2, and instrument can be repeatedly used.
