Abstract
The invention discloses a wellbore sundry fishing, and belongs to the technical field of application of oil production engineering, aiming to solve the technical problem that wellbore sundries are difficult to fish. The technical scheme includes that an anchor body is spirally connected with a main rod, the anchor body is connected with a fishing claw on the lower side through pin shafts, and a stop ring is sleeved on a tailstock which is in threaded connection with the main rod. The wellbore sundry fishing anchor has the advantages that for wells with the shut-in well depth within several meters from wellbores, professional operation teams and equipment are not needed, and the sundries can be fished out by relying on direct manual operation; therefore, the wellbore sundry fishing anchor is convenient to implement and low in treatment cost.
Description
Technical field
The invention belongs to petroleum production engineering applied technical field, 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 invention provides 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 present invention solves the technical scheme that its technical problem takes: a kind of pit shaft sundries fishing anchor forms by dragging for pawl, main body, tailstock, shelves ring, mobile jib, bearing pin, 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 invention has the beneficial effects as follows, 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, convenient and easy, disposal cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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 present invention is further illustrated: 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.
