The utility model is characterized in that a longitudinal strip window is arranged on the wall of the guide body, a guide wheel is provided on the longitudinal strip window, the guide wheel is provided with a pin axle, the pin axle is fixed on the longitudinal strip window, the lower end of the guide body is provided with an inner screw and connected with the body, a locking block is provided on the guide body, three equal-angle oblique through holes are arranged on the body wall, the bottom of the oblique is provided with a steel ball, the upper portion of the steel ball is provided with a compression spring, a pipe plug blocks the oblique hole on the upper portion of the compression spring, the inscribed circle diameter of three steel balls is smaller than the inner-hole diameter of the body. The body lower end screw is connected with an inductive shoe, the lower mouth of the inductive shoe is an inner oblique conical surface, a locking block is provided on the body, the inductive shoe is also provided with a locking shoe. When the side-open three-ball salvager is used to salvage well-log instruments, the cable is needless to cut, thereby safe release is realized.
Description
Technical field
The utility model relates to a kind of oil and salvages special tool, particularly handles the fishing tool of down-hole accident in the oil reservoir logging construction.
Background technology
In the oil reservoir logging manufacturing process, often have various trouble of lost tool in holes and fall in the well, as drilling tool, logger, sucker rod or cable etc.Downhole tool taking place fall after the well accident, need be lowered to fishing tool it is salvaged out.At present, in the well logging industry, domestic and international employed downhole instrument releasing tool is slip socket and three ball fishers basically, adopts the core-theaded type Refloatation method to salvage the well instrument.But core-theaded type is salvaged instrument, shortcoming be: salvaging in the construction needs to cut the outage cable, causes the heavy losses of cable; In addition, the direct unfreezing situation of optical viewer, cable in the construction, difficulty of construction is big; Secondly, connect at every turn and need many people when changing drilling rod and draw cable, penetrate, connect in drilling rod, construction intensity is big.
The utility model content
The purpose of this utility model is: provide a kind of side to drive three ball fishers, make in the salvaging process, do not need to cut the outage cable.Overcome the core-theaded type Refloatation method and salvage the deficiency of well instrument; Realize the purpose of safe unfreezing fishing.
The technical solution adopted in the utility model is: the side is driven three ball fishers and is made up of guide way, directive wheel, body, guide shoe, and guide way is cylindric, and there is internal thread the guide way upper end, can connect oil pipe and drilling rod.It is characterized in that: have the longitudinal strip window on the wall of guide way.A directive wheel is arranged on the longitudinal strip window, and directive wheel has bearing pin, and bearing pin is fixed on the longitudinal strip window.There is internal thread the lower end of guide way and connects body.Latch segment is arranged on the guide way.The oblique through hole that 3 five equilibrium angles are arranged on the body wall, steel ball is arranged at the inclined hole bottom, and the compression spring is arranged at steel ball top, and spring top is by plug shutoff inclined hole.The inscribed circle diameter of three steel balls is less than the body diameter of bore.The body lower end guide shoe that is threaded, the guide shoe end opening is interior scalene cone.Latch segment is arranged on the body, latch segment is arranged on the guide shoe.
Summary the utility model use:, use the utility model to salvage when logger is blocked in the down-hole.Cable put into the other longitudinal strip window of driving three ball fishers on ground; Open each latch segment, cable is put into guide way, body and guide shoe.When cable is put into each latch segment of packing into after three ball fishers are driven on the side.Connecting oil pipe and drilling rod lower tubular column on guide way top salvages.Three ball fishers are driven to lower going-into-well in the side, and cable skids off smoothly along directive wheel.Open the guide shoe arrival instrument top of three ball fishers continues to transfer when the side.The Malong head at logger top is pushed intrinsic three steel balls open obliquely by scalene cone in the guide shoe, compresses three springs, changes the public inscribed circle diameter of three steel balls, and the Malong head at logger top enters in the body by three steel balls.Three steel balls return to the origin-location at gravity and spring thrust effect lower edge inclined hole, block the Malong head at logger top, catch logger and salvage ground.Adopt the utility model to salvage, need not cut off logging cable other drive three ball fishers can be down to the logger top.
Effect of the present utility model is: adopt the other three ball fishers of opening when salvaging logger, need not cut off cable, can understand the unfreezing situation by downhole instrument, reach the purpose of safe unfreezing.The utility model also has compact conformation, easy construction reasonable in design in addition, shortens advantages such as construction period, attenuating operating expenses.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is the other three ball fisher structural profile schematic diagrames of opening of the utility model.
Among the figure, 1. guide way, 2. directive wheel, 3. bearing pin, 4. latch segment, 5. body, 6. latch segment, 7. plug, 8. spring, 9. steel ball, 10. guide shoe, 11. latch segments.
The specific embodiment
Embodiment: consult accompanying drawing.Three ball fishers are driven on the side, and guide way 1 is cylindric, and external diameter is 62 millimeters, 800 millimeters of length.There is internal thread guide way 1 upper end, can connect oil pipe.Having a width on the wall of guide way 1 is 25 millimeters, and length is 300 millimeters longitudinal strip window, and a directive wheel 2 is arranged on the longitudinal strip window.Directive wheel 2 has bearing pin 3, and bearing pin 3 is fixed on the longitudinal strip window.There is internal thread the lower end of guide way 1 and connects body 5, and latch segment 4 is arranged on the guide way 1.The oblique through hole that 3 five equilibrium angles are arranged on body 5 walls, 15 millimeters of the diameters in hole.Each oblique via bottoms has a steel ball 9, and compression spring 8 is arranged at steel ball 9 tops, and spring 8 tops are by plug 7 shutoff inclined holes.The inscribed circle diameter of three steel balls 9 is less than 12 millimeters of body 5 diameter of bores, and steel ball is exposed at a part outside the hole, but can not drop out.The body 5 lower ends guide shoe 10 that is threaded, guide shoe 10 end openings are interior scalene cone, and latch segment 6 is arranged on the body 5, and latch segment 11 is arranged on the guide shoe 10.Latch segment 4, latch segment 6 and latch segment 11 are dove-tail.
