Abstract
The utility model relates to a pipe wreck removal tool for downhole busywork, comprising a upper joint (1), a generating cone (2), O-shaped sealed ring (3), a steel ball (4), a piston (5), a conic inner body (6) and a guide shoe. The lower end of the generating cone and the upper end of the generating cone are respectively connected to an upper joint and a guide shoe. A piston is provided on the upper part of the conic inner body and a steel ball is arranged above the central hole of the piston. The O-shaped sealed ring is arranged inside the sealed groove which has a round outer surface. The conic inner body is arranged at the lower part of the generating cone chamber and the steel ball at the upper end of the generating cone chamber matches with the lower part of the central hole of the piston. The utility model has the advantages of original design concept and reasonable structure design. The utility model introduces the novel principle of the wire-cutter and can lock the pipe wreck, thus, realizing fishing effect without dressing the top. This utility model can simply construction procedure, shorten construction time period, save cost and bring good economic benefit.
Description
Technical field:
The utility model relates to a kind of downhole tool that is used for oil field well workover construction operation, belongs to the workover tool class.
Background technology:
Along with oil field development, the prolongation of oil-water well production time, oil-water well down-hole technology status worse and worse, the tubing class trouble of lost tool in hole well a few days becomes to increasing, and oil, well ordinary production are constituted harmful effect, must down-hole fragment tubing be salvaged out by the well workover construction operation.Because tubing class junk falls behind the well because of impact force action, bend, fracture, breakage such as splitting, form irregular shape, and the desirable down-hole fishing tool of on-the-spot at present shortage, traditional salvaging mode is to take first milling top of fish to make it into regular shape before dragging for more, carries out fishing again, thereby construction operation program complexity, long construction period, the operating cost height.
Summary of the invention:
The utility model purpose is to provide a kind ofly can need not to repair the damaged tubing fishing tool in down-hole that the junk top of fish can directly be salvaged in advance.
The utility model is to realize like this.
This kind trouble of lost tool in hole fishing tool is made up of top connection, female coupling tap, " O " RunddichtringO, steel ball, piston, inner cone and guide shoe, and the female coupling tap upper and lower end is respectively with top connection and the guide shoe of being threaded; Female coupling tap chamber internal upper part is provided with piston, and piston mesopore top is provided with steel ball, and " O " RunddichtringO is housed in the periphery seal groove; The bottom is provided with inner cone in the female coupling tap chamber, and its upper end spherosome is equipped mutually with piston mesopore below.When construction is salvaged in well workover, the top connection on this device top is connected salvaging drilling rod lower end, down to the top of fish position, drill string is transferred in rotation, guide shoe by this device bottom is introduced fishing socket with splitting oil pipe top of fish, drop into steel ball at well head then and make it seat and be placed on the piston mesopore ball seat and build the pressure, force inner cone descending, push damaged oil pipe top of fish and locking.After finishing above-mentioned operation, the upper lifting pipe post changes according to the weight indicator reading and can judge whether junk has dragged for and obtain.
The utility model is novel, reasonable in design, and it utilizes the principle of cutting pliers that fragment tubing is blocked, make and do not repair top of fish and can directly salvage and become a reality, utilize this instrument can simplify the construction operation program, shorten construction period, save cost, obtain good economic benefit.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
As shown in the figure, the utility model is made up of top connection 1, female coupling tap 2, " O " RunddichtringO 3, steel ball 4, piston 5, inner cone 6 and guide shoe 7, and its structure, assembled relation are as follows: female coupling tap 2 upper and lower ends are respectively with top connection 1 and the guide shoe 7 of being threaded; Female coupling tap 2 chamber internal upper parts are provided with piston 5, and piston 5 mesopores top is provided with steel ball 4, and " O " RunddichtringO 3 is housed in the periphery seal groove; The bottom is provided with inner cone 6 in female coupling tap 2 chambeies, and its upper end spherosome is equipped mutually with piston 5 mesopores below.Wherein, female coupling tap 2 is a pipe body, its upper and lower end is respectively equipped with top connection 1, guide shoe 7 and is connected with internal thread and external screw thread, the inner headed face middle part is provided with round platform, internal diameter is up-small and down-big, piston 5 is a hollow circular cylinder, and its mesopore top is horn-like conical surface ball seat, and the bottom is concave spherical surface in order to match with inner cone 6 upper ends.Inner cone 6 is a hollow circular cylinder, and a round platform is arranged at its top, and the upper end is spheroidal, and the periphery lower end is a taper seat.
