Abstract
The utility model relates to a fishing tool of fallen objects in a drilling well, which is a fishing socket with steel wire ropes and comprises a crossover joint, a socket body and steel wires, wherein the lower end of the crossover joint and the upper end of the socket body are fixedly installed together; the inner walls of different positions of the socket body from down to top are respectively distributed with at least three circles of installing holes; and each installing hole is internally provided with a steel wire; the inner ends of the steel wires are fixedly installed in the installing holes; the outer ends of the steel wires pass through the center axis of the socket body and are mutually intersected; and a steel wire net basket is formed among the steel wires. The fishing socket has reasonable and compact structure and convenient use; and the steel wire net basket formed among steel wires can effectively clamp slender rod parts fallen into the well, thus improving the fishing success rate of the slender rod parts fallen into the well.
Description
One, technical field
The utility model relates to the trouble of lost tool in hole fishing tool, is a kind of wire rope fishing socket.
Two, background technology
Slip socket is widely used in oilfield process as the fishing tool of trouble of lost tool in hole, but this instrument can't be salvaged external diameter less than 48 millimeters slender rod piece, main cause is subjected to the restriction of hole diameter and junk external diameter when being slip socket work, if borehole diameter is excessive, the junk external diameter is too small, causes the junk side to lean against on the borehole wall, and slip socket can't enter junk, and, there is not the supporting slip insert of fishing for slender rod piece when junk rod member external diameter during less than 48 millimeters.
Three, summary of the invention
The utility model provides a kind of wire rope fishing socket, has overcome the deficiency of above-mentioned prior art, and it can solve the problem that slender rod piece junk down-hole is difficult to salvage effectively.
The technical solution of the utility model realizes by following measure: plant the wire rope fishing socket, comprise crossover sub, cylindrical shell, steel wire, the lower end of crossover sub and the upper end of cylindrical shell are fixed together, be distributed with the installing holes that are no less than three circles respectively on the inwall of diverse location from bottom to top at cylindrical shell, in each installing hole, steel wire is arranged, the inner of steel wire is fixedly mounted in the installing hole, and the outer end of steel wire is passed the central axis of cylindrical shell and intersected mutually, forms the gauze wire cloth basket between the steel wire.
Be further optimization and/or improvements below to above-mentioned utility model technical scheme:
The lower end of above-mentioned cylindrical shell can be installed with horn mouth formula guide shoe.
The central axis of above-mentioned steel wire and cylindrical shell can be 45 degree angles.
Above-mentioned steel wire length can be grown 10 to 15 millimeters than cylindrical shell radius.
The upper end of above-mentioned crossover sub can be installed with drill collar, drilling rod and kelly bar from bottom to top in regular turn, and the upper end screwed connection of the lower end of crossover sub and cylindrical shell together.
Every 50 centimetres to the 60 centimetres installing holes that can be distributed with a circle, every circle has 8 to 12 installing hole to above-mentioned cylinder inboard wall from bottom to top, and the diameter of installing hole is 8 to 10 millimeters.
The utility model reasonable and compact in structure, easy to use, can effectively block the slender rod piece that falls into well by forming the gauze wire cloth basket between the steel wire, thereby improve the fishing success ratio of the slender rod piece that falls into well.
Four, description of drawings
Accompanying drawing 1 is looked the sectional structure schematic diagram for master of the present utility model.
Accompanying drawing 2 for A-A in the accompanying drawing 1 to analyse and observe the structure for amplifying schematic diagram.
Coding in the accompanying drawing is respectively: 1 is crossover sub, and 2 is cylindrical shell, and 3 is steel wire, and 4 is horn mouth formula guide shoe, and a is an angle.
Five, the specific embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
Shown in accompanying drawing 1,2, this wire rope fishing socket comprises crossover sub 1, cylindrical shell 2, steel wire 3, the upper end of the lower end of crossover sub 1 and cylindrical shell 2 is fixedly installed togather, be distributed with the installing hole that is no less than three rows (or circle) respectively on the inwall of diverse location from bottom to top at cylindrical shell 2, steel wire 3 is arranged in each installing hole, the inner of steel wire 3 is fixedly mounted in the installing hole, and the outer end of steel wire 3 is passed the central axis of cylindrical shell 2 and intersected mutually, forms the gauze wire cloth basket between the steel wire 2.
Can according to actual needs above-mentioned wire rope fishing socket be made further optimization and/or improvements:
As shown in Figure 1, junk enters in the cylindrical shell 2 for convenience, and the lower end of cylindrical shell 2 is installed with horn mouth formula guide shoe 4.
As shown in Figure 1, steel wire 3 is 45 degree angle a with the central axis of cylindrical shell 2, like this, is convenient to junk and easily advances to be difficult for.
As shown in Figure 1, the length of steel wire 3 is grown 10 to 15 millimeters than the radius of cylindrical shell 2, like this, and easier overlapping between the steel wire 3.
According to actual conditions, be installed with drill collar, drilling rod and kelly bar from bottom to top in regular turn from the upper end of crossover sub 1, the upper end screwed connection of the lower end of crossover sub and cylindrical shell can be salvaged junk according to the degree of depth that falls into of junk together like this.
As shown in Figure 1, according to actual needs, it is that the installing hole of a circle (or row) (is 50 centimetres to 60 centimetres of spaces between every circle that cylinder inboard wall just is distributed with 8 to 12 every 50 centimetres to 60 centimetres from bottom to top, every circle has 8 to 12 installing hole), the diameter of installing hole is 8 to 10 millimeters.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
Use of the present utility model: in drilling operation course, when the slender rod piece junk is arranged, the upper end of crossover sub drill collar, drilling rod and kelly bar have been fixedly mounted from bottom to top in regular turn, then in the lower going-into-well, junk enters in the cylindrical shell 2 and enters in the gauze wire cloth basket that forms between the steel wire 3, the utility model is upwards mentioned, and junk is stuck in the gauze wire cloth basket, at last junk is salvaged from well.
