Description
Technical field
The utility model relates to that a kind of wearing bush and special use that is used for the well head casing head sent into, the taking-up instrument, belongs to the drilling equipment field.
Background technology
In oil exploration drilling, situ of drilling well will descend one deck sleeve pipe whenever being drilled into certain well depth, and a kind of nonvolatil well-control equipment will be installed on sleeve pipe then: casing head, another kind of important well-control equipment is installed again: preventer on casing head; These well-control equipments are installed and just can carry out next level drillng operation after pressure testing are qualified, in drilling operation course because tripping out and be lowered to all of the rotation of drilling tool and drilling tool can particularly the sealing position in the casing head and shoulder produce wearing and tearing (because this sealing position and shoulder are the positions of internal diameter minimum in the whole well head) and such wearing and tearing can cause the seal failure of the hanger behind another layer sleeve pipe down to well head at every turn, the casing head of grinding away after just giving completion when the sealing position of casing head inside has stayed accident potential, for fear of the generation of accident, whenever new installation one deck casing head all can be adorned a wearing bush that often take out inspection or change inside; Checking in the past and changing wearing bush all is that drilling tool just can carry out in playing completion, this is because existing wearing bush is respectively with the structure of fetching and delivering instrument: the outside of wearing bush is provided with two installing holes at least, its cylindrical shell is provided with several draw-in grooves, the supporting instrument of fetching and delivering is the mandrel that the upper end is provided with the drill rod thread hole, on mandrel, be provided with several and the corresponding snap pin of draw-in groove, be similar to the draw-in groove on the lamp socket and the snap pin of bulb, when operating personnel attempt in the drilling well some time midway wearing bush to be taken out inspection, several snap pins on the mandrel will be aimed at several draw-in grooves on the wearing bush, also to rotate to an angle and just can tangle wearing bush, take out then; Because wearing bush can not touch (height of sitting at the bottom of the different drilling derricks is different) cannot see under the preventer from about turntable surface 5-10 rice, only with feeling operation, facts have proved that this operation mostly comes back after a vain attempt, can not satisfy frequent taking-up and pick up the requirement of looking into and changing, just the snap pin of fetching and delivering on the instrument be damaged by pressure owing to operation is bad simultaneously; Along with the raising of drilling tool and drill quality is gone into well when a drill bit and may be drilled a week or longer time, cannot check the abrasion condition of wearing bush for a long time, by the time pull out of hole when checking, wearing bush may be worn through (bad), and the position of casing head sealing simultaneously also is damaged; In order to check and change wearing bush; the protective sleeve tube head; could take out wearing bush after just having only the interior drilling rod of taking-up well, drill bit; reach for well depth that drilling rod is taken out in 6000 meters drilling well, drill bit need spend nearly 40 hours time; rig is that large-scale diesel engine directly drives or generates electricity and drives the electric drilling machine whim and finish; such inspection cost is too high, and the day of rig is taken, oil consumption is general must spend hundreds thousand of yuans.
