Technical field
the utility model relates to rotating blowout preventer assembly and shirks technical field of tools, is that a kind of rotating blowout preventer assembly shirks rope.
Background technology
about rotating the assembly security tool that neither one is ready-made in dismounting (pull-off from drilling rod) process in existing under balance pressure drilling equipment, thus in this process, the fixed instrument of rotation assembly can be made can to bring for operation when drilling rod is carried, namely do not have specification there is no code yet, more there is no standard.
a kind of method more common in Contraction in Site, substantially be carry out bolt by ropes such as wire rope, the rope made of hemp, iron chains to draw assembly, other end is affiliated to be had on the elevator of drilling tool at seat, and the weight by its drilling tool is carried out bolt and held rotation assembly, now tourist bus is carried, detach rotation assembly and fulfil assignment.There is following shortcoming in it: 1. the degree of adhesion of assembly and drilling rod is uncertain, causes when shirking assembly and need to adopt the rope of what intensity uncertain.2., as used the rope made of hemp, post-rift rope can not cause any impact (rope made of hemp fall well then be easily grated), if use steel wire cable, and the down hole problem very likely causing trouble of lost tool in hole to cause after fracture generation.3. the rope owing to using has lack of standard, usually only has an origin of force when bolt hangs assembly lower glue core, upper carry drilling rod time due to discontinuity, certain damage can be caused to rotation assembly inside.
another kind shirks and rotates the way of assembly is under empty well state, putting into well, again setting hanging with the drill rod stand column rotating assembly well head, by closing the clip fluid cylinder on rotating blowout preventer, blocking rotation assembly, then row carries drilling rod shirks object to reach.There is following shortcoming in it: 1. the method does not belong to the operation of Unbalance technique service regulation.2. operating procedure is many, need operating personnel back and forth up and down well head be affiliated to puffer rope and locking, unblock vessel safety bolt, there is certain danger and uncertainty.
therefore, the rotating blowout preventer assembly instrument that shirks of existing use has the following disadvantages in actual use: use rope lack of standardization, rotate the inner easy damaged of assembly, fracture wire rope easily causes trouble of lost tool in hole, clip fluid cylinder carries drilling rod and shirk by closing and there is potential safety hazard.
Summary of the invention
the utility model provides a kind of rotating blowout preventer assembly and shirks rope, overcome the deficiency of above-mentioned prior art, its can effectively solve the existing rotating blowout preventer assembly instrument that shirks exist use rope lack of standardization, rotate the inner easy damaged of assembly, fracture wire rope 1 easily causes trouble of lost tool in hole, clip fluid cylinder carries drilling rod shirk by closing the problem that there is potential safety hazard.
the technical solution of the utility model is realized by following measures: a kind of rotating blowout preventer assembly shirks rope, comprises wire rope, steel cable cutting ferrule and card suspension member; Two ends of wire rope form becket bridle respectively by steel cable cutting ferrule is fixing, two becket bridles are fixed with card suspension member respectively, card suspension member comprises card and hangs transverse sheet and be connected riser, card is hung one end of transverse sheet and to be connected as a single entity with the upper end being connected riser and L-shaped, the middle part that transverse sheet hung by card is provided with card hanging hole, the lower end connecting riser is provided with bridle port, and becket bridle is arranged on through bridle port and connects on riser.
here is the further optimization and/or improvements to above-mentioned utility model technical scheme:
above-mentioned card hanging hole can be circular hole, and the diameter of card hanging hole is 18 centimetre to 22 centimetres.
above-mentioned bridle port can be circular hole, and the diameter of bridle port is 18 centimetre to 22 centimetres.
the length of above-mentioned wire rope can be 13 meter to 17 meter.
above-mentioned steel cable cutting ferrule can be cast iron steel cable cutting ferrule.
the utility model reasonable and compact in structure, easy to use, it hangs transverse sheet by card and card hanging hole can convenient, fast, firmly be fixed on rotating blowout preventer assembly, effectively stop the generation of trouble of lost tool in hole, simultaneously, it can make job step simple, improves safety and the normalization of field-strip.
