A kind of pit shaft sundries fishing anchor

Technical field

The utility model belongs to petroleum production engineering applied technical field, and what be specifically related to is a kind of pit shaft sundries fishing anchor.

Background technology

In oilfield process, stopping production is carried out to the oil-water well of down-hole shut-in well, by undesirable, thrown into foreign material sometimes, and foreign material in well are salvaged difficulty.

Summary of the invention

For solving down-hole foreign material, salvage difficult problem, the utility model provide a kind of can be with manpower the foreign material fisher at well head direct control, to the shut-in well degree of depth apart from well head number meter with interior well, do not use full-time job execution troop and equipment, by manpower direct control, junk can be pulled out, convenient and easy, disposal cost is low.

The technical scheme in the invention for solving the technical problem is: a kind of pit shaft sundries fishing anchor by dragging for pawl, main body, tailstock, shelves ring, mobile jib, bearing pin forms, main body is connected with spiral with mobile jib, main body below with drag for pawl and be connected with bearing pin, shelves ring set on tailstock, tailstock with mobile jib to be threaded.

The beneficial effects of the utility model are, the shut-in well degree of depth, apart from well head number meter with interior well, is not used to full-time job execution troop and equipment, by manpower direct control, junk can be pulled out, and convenient and easy, disposal cost is low.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure, by 1, dragging for pawl, 2 main bodys, 3 tailstocks, 4 grades of rings, 5 mobile jibs, 6 bearing pins forms.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, a kind of pit shaft sundries fishing anchor by dragging for pawl 1, main body 2, tailstock 3, shelves ring 4, mobile jib 5, bearing pin 6 forms, main body 2 is connected with spiral with mobile jib 5, main body 2 belows with drag for pawl 1 and be connected with bearing pin 6, shelves ring 4 is enclosed within on tailstock 3, tailstock 3 with mobile jib 5 to be threaded.

During application, will drag for and be anchored more piece roofbolt G.I.H, be rotated in the forward mobile jib 5, main body 2 and mobile jib 5 between descending under the spiral effect of paying, by bearing pin 6, the pawl 1 that drags for of both sides is gathered, thereby down-hole foreign material is caught, outside proposition well, complete a salvage.
