Abstract
The utility model relates to oil field well cementation tool, is specifically related to a kind of rotary cement cap.Rotary cement cap, comprise base, pressure cap, suspension ring group, the cross section of base and pressure cap is down " recessed " character form structure, the external diameter of base is less than the internal diameter of pressure cap, the end face that base is corresponding with the upper end cover of pressure cap has central through hole, one of suspension ring group, through central through hole, the position that pressure cap is corresponding with on the sidewall of base has peephole.The utility model structure is simple, makes admission data become convenient and swift, shortens the time of admission data, reduce cost, technician can be grasped in time and stop well performance.
Description
Technical field
The utility model relates to the long well shaft that stops of oil exploitation and protects field, is specifically related to a kind of rotary cement cap.
Background technology
In oil recovery is produced, because there are wellbore damage problem or geology needs, need carry out dynamic closing well to part oil-water well, after oil-water well closing well, well head is covered with cement cap; At present, cement cap is one and falls the cement cap of " recessed " character form structure, and cement cap is marked with pound sign, stops the well time, closing well reason etc.; During use by crane sling be buckled in dynamic closing well well head on; When the data of admission, need to use crane to sling cement cap, make admission data cost high, and cause data not enroll in time, technician just can not grasp in time and stop well performance.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned prior art Problems existing, provides one to facilitate admission data, makes admission data convenient and swift, and technician can grasp the rotary cement cap stopping well performance in time.
The technical solution of the utility model is:
Rotary cement cap, comprise base, pressure cap, suspension ring group, the cross section of base and pressure cap is down " recessed " character form structure, the external diameter of base is less than the internal diameter of pressure cap, the end face that base is corresponding with the upper end cover of pressure cap has central through hole, one of suspension ring group, through central through hole, the position that pressure cap is corresponding with on the sidewall of base has peephole.
Described suspension ring group comprises suspension rod, dividing plate and nut, and suspension rod is with externally threaded screw mandrel, and suspension rod upper end connects suspension ring; Dividing plate is annular slab, and its external diameter is greater than the internal diameter of the central through hole on the upper surface of base and pressure cap, and suspension rod is through dividing plate, and dividing plate is between the upper surface of base and pressure cap lower surface, and suspension rod is through nut, and suspension rod and nut screw connection are fastened base and pressure cap.
The utility model structure is simple, makes admission data become convenient and swift, shortens the time of admission data, reduce cost, technician can be grasped in time and stop well performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 base 2 pressure cap 3 peephole 4 peephole 5 nut 6 central through hole 7 dividing plate 8 central through hole 9 suspension rod 10 suspension ring.
Detailed description of the invention
Rotary cement cap, comprise base 1, pressure cap 2,10 groups, suspension ring, the cross section of base 1 and pressure cap 2 is down " recessed " character form structure, the external diameter of base 1 is less than the internal diameter of pressure cap 2, the end face that base 1 is corresponding with the upper end cover of pressure cap 2 has central through hole 6 and central through hole 8, one of 10 groups, suspension ring, through central through hole 6 and central through hole 8, the position that pressure cap 2 is corresponding with on the sidewall of base 1 has peephole 3 and peephole 4.
10 groups, described suspension ring comprise suspension rod 9, dividing plate 7 and nut 5, and suspension rod 9 is with externally threaded screw mandrel, and suspension rod 9 upper end connects suspension ring 10; Dividing plate 7 is annular slab, and its external diameter is greater than the internal diameter of central through hole 6 and central through hole 8, and suspension rod 9 is through dividing plate 7, and dividing plate 7 is between the upper surface of base 1 and pressure cap 2 lower surface, and suspension rod 9 is through nut 5, and suspension rod 9 coordinates be fastened base 1 and pressure cap 2 with nut 5.
The utility model is contained on well top stopped for long time by rotary cement cap, can locate by pound sign; During admission data, loosen suspension ring 10 and suspension rod 9, rotate pressure cap 2 with hand, the peephole 3 on pressure cap 2 is aligned with the peephole 4 on base 1, just can enroll data; Enroll data, rotated pressure cap 2, the peephole 3 on pressure cap 2 has been staggered with the peephole 4 on base 1, then tightens suspension rod 9, pressure cap 2 can not be rotated, complete the admission work of data.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
