Abstract
The utility model discloses a grinding and milling combined fishing device applicable to the engineering of oil and gas drilling. The utility model is used for processing the drill rod sticking by the cement solidification in a sleeve tube, which is composed of a fishing joint 2 fastened on the lower part of a sleeve tube 4 and a thickening grinding and milling shoe 6. On the fishing joint, a by-pass hole 1 and a taper tap 3 are arranged; at the lower part of the thickening grinding and milling shoe, a carbide alloy tool 7 is arranged; the length of a sleeve cylinder can be determined according to the length of the drilling tool by the drill sticking. When the drill sticking by the cement solidification in the sleeve tube and the drilling tool are taken out, the tool is inserted, and the accident of drill tool sticking by the cement solidification can be solved rapidly and reliably. The utility model has the advantages of simple structure, high safety, non-stop pump fishing, etc.
Description
The utility model is a kind of in the oil and natural gas drilling project, handles the milling combination fisher of the bit freezing that thes cement solidifies in the sleeve pipe.
The processing poor reliability of bit freezing is theed cement solidifies in existing cover drags in the combination tool sleeve pipe, easily cause accident disconnected, that fall, block, can not guarantee construction safety, disclose a kind of multi-functional fishing socket in CN2045421U, it is formed by connecting fishing cup, return connector, inner core, urceolus, guide shoe and claw etc.By draw expanding a well, grinding, grabbing and drag for and strong magnetic is fished for, realize that it salvages function.Its weak point is: can not solve theed cement solidifies salvaging problem in sleeve pipe of drilling rod, can not cut drilling rod body and joint, around button and make-up salvaging.Same CN2038950U, open drill extractor all can not overcome the above problems among the CN2038951U, and complex structure, uses inconvenience.
The purpose of this utility model designs a kind of to the bit freezing that thes cement solidifies in the sleeve pipe exactly, particularly snaps in the drilling rod of big external diameter in sleeve pipe, annular gap hour energy is pulled drilling rod out by root milling combination fisher.
The purpose of this utility model realizes by following structure: milling combination fisher, the fishing joint and the thickening milling footwear at two ends are formed up and down by being fastened on sleeve respectively for it, at the fishing joint middle part one by-pass prot is arranged, so that pressure liquid flushing passing through sleeve, arrive the thickening milling footwear of its lower end, at fishing joint bottom die nipple (or female coupling tap), be welded with carbide cutter tool at thickening milling sole part.
Be fastened on fastness on the sleeve in order to improve fishing joint and thickening milling footwear, can with fishing joint and thickening milling footwear elder generation's spot welding or screw thread on sleeve, strengthen fastening fishing joint and thickening milling footwear with lining respectively.
Description of drawings of the present utility model is as follows:
Fig. 1 is the structural representation that partly cuts open of the present utility model.
Among the figure: 1. by-pass prot, 2. fishing joint, 3. die nipple, 4. sleeve, 5. lining, 6. thickening milling footwear, 7. carbide cutter tool, 8. lining.
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1: the utility model by the salvaging that is fastened on sleeve two ends about in the of 4 respectively connect 2 and thickening milling footwear 6 form, the by-pass prot 1 of one discharge pressure liquid with cooling and lubricating thickening milling footwear arranged at the fishing joint middle part, one die nipple 3 is arranged in the fishing joint lower end, it can salvage object (as drilling rod) limit tapping to the quilt through milling, the limit fastening, thickening milling sole part has carbide cutter tool 7, the outer wall of object is salvaged in its energy milling, make it to separate with the casing wall or the borehole wall, so that fishing joint tapping, fastening and salvaging, thickening milling footwear are steel hollow cylinders, its thickness is 15-50mm.
Be fastened on fastness on the sleeve in order to improve fishing joint and thickening milling footwear, can on sleeve, be locked with lining 8 and 5 respectively then with fishing joint and thickening milling elder generation's spot welding or with the screw thread fastening.
When making, the utility model can in fishing joint, open a by-pass prot, its lower end adopts die nipple (also can adopt right-hand thread or back taper according to the situation of being blocked object, right-hand thread or left-hand thread female coupling tap, as: being blocked object is right-hand drill pipe, then the left-hand thread female coupling tap can be adopted in the fishing joint lower end, make its tapping, during hitch, drilling rod lower end back-off, so that not termination of pumping is salvaged), fishing joint can be welded on the sleeve and lining 8 is strengthened fastening, sleeve can be a seamless steel pipe that certain wall thickness is arranged, its length can be decided according to being salvaged object length, thickening milling footwear are with after the sleeve lower end is connected, and fastening by lining 5 reinforcements again, thickening the milling footwear is steel air Cylinders, evenly gather and be welded with carbide alloy column cutter piece in its lower surface, carbide cutter tool is a hard wolfram steel granule post.
Use the utility model safety, reliable, can improve effect. As when leaving the drilling rod that is theed cement solidifies stuck in the sleeve pipe, select the fisher of dimension, it is lowered to, add earlier the pressure of 3.0～5.0KN The power milling is inserted in the sleeve drilling rod, then carries out thread making when fishing joint contact drilling rod, hitch, and drilling rod lower end back-off is realized salvaging, and arrives milling shoes lower end lubrication because by-pass prot can make pressure liquid through sleeve, thereby has realized not termination of pumping salvaging.
The utility model compared with prior art has easy to use, and is simple in structure, and safety is reliable, can improve the advantages such as effect.
Claims (6)
