Abstract
The utility model relates to a large-displacement well drilling and completing tool, in particular to a guide tool for a wellhead pressurizing tool. A female fastener is designed at the upper end of an upper connector of the tool, a limit sleeve is connected with the lower end of the upper connector, the inner wall of the lower end of the limit sleeve is designed into an inner sphere, the outer surface of the upper end of a lower bearing body is designed into a spherical rotor and is mounted in the inner sphere of the limit sleeve, the spherical rotor of the lower bearing body can be matched to the inner sphere of the limit sleeve to rotate, the upper connector and the lower bearing body are both provided with circulating holes in the center, and a lower joint is designed at the lower end of the lower bearing body. The guide tool can be connected to the middle of a pressurizing tool, the pressurizing tool can freely rotate and optionally adjust angle when the pressurizing tool is connected with a tubular column, and a screw thread of a sleeve is protected. The defects that the existing wellhead pressurizing tool cannot freely bend when being connected with the tubular column and the screw thread of the sleeve is easy to damage are overcome.
Description
Technical field:
The utility model relates to a kind of extended reach well and bores completion tool, particularly a kind of steering tool for the well head pressurizing tool.
Background technology:
Along with the continuous application of extended reach well drilling technology, except the problem that will solve the drilling well aspect, also to take into full account the problem that is lowered to smoothly of completion tubular column.Can assist completion tubular column to be lowered to smoothly by using the well head pressurizing tool, but well head pressurizing tool body is longer, rigidity is strong, can not bend, therefore very big in difficulty when sleeve pipe on rat hole or the ramp is connected, do not have under the prerequisite of supporting machinery chemical industry tool, the connect hours is long, very easily destroys the sleeve pipe screw thread.
The utility model content:
The technical problems to be solved in the utility model provides a kind of steering tool for the well head pressurizing tool; this instrument has realized being connected to the middle part of pressurizing tool; make pressurizing tool when connecting tubing string, can rotate freely and arbitrarily adjust angle, protective casing screw thread.Having overcome existing well head pressurizing tool can't free bend when connecting tubing string, very easily destroys the deficiency of sleeve pipe screw thread.
Technical solution adopted in the utility model is: a kind of steering tool for the well head pressurizing tool comprises connector; Upper connector upper end is designed with box, the lower end connects stop collar, stop collar lower end inwall is designed to Internal Spherical Surface, bearing down body upper end external surface is designed to the rotary body of sphere and is installed in the Internal Spherical Surface of stop collar, the rotation that can match of the spherical rotary body that bears down body and the Internal Spherical Surface of stop collar, upper connector and lower bear the body center and all have circulation port time bears the body lower end to be designed with lower contact.
Bear down between the spherical rotary body of body and the stop collar O-ring seal is installed.
The beneficial effects of the utility model are: the utility model is owing to adopted match with the Internal Spherical Surface of the stop collar mode of rotation of the spherical rotary body that time bears body; thereby has a middle part that can be connected to pressurizing tool; make pressurizing tool when connecting tubing string, can rotate freely and arbitrarily adjust the function of angle, protective casing screw thread.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of steering tool for the well head pressurizing tool comprises connector 1; Upper connector 1 upper end is designed with box, the lower end connects stop collar 2, stop collar 2 lower end inwalls are designed to Internal Spherical Surface, bearing down body 3 upper end external surfaces is designed to the rotary body of sphere and is installed in the Internal Spherical Surface of stop collar 2, the rotation that can match of the spherical rotary body that bears down body 3 and the Internal Spherical Surface of stop collar 2, upper connector 1 and bear body 3 centers and all have circulation port down time bears body 3 lower ends to be designed with lower contact.Bear down between the spherical rotary body of body 3 and the stop collar 2 O-ring seal is installed.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
