Abstract

The utility model discloses a deflecting device for horizontal drilling, by the top connection that can be connected with the screw rod drilling tool, urceolus and built-in flexible drill pipe are constituteed, wherein the urceolus is by the mutual grafting series connection of the pipe nipple joint of two more than different diameters of pin joint and is constituteed, be equipped with the toper groove at the both ends of pipe nipple joint, one side is opened has the circular recess, install the spring in the circular recess of urceolus one side, by the direction of urceolus control deflection, drive the universal flexible hollow shell rotation of built-in urceolus by the mandrel of screw rod drilling tool, transmit the moment of torsion for the drill bit and carry out the deflection construction. Compared with the prior art, the utility model has the advantages of simple structure, low in manufacturing cost, construction convenient operation etc.

Description

A kind of horizontal drilling kick-off device
The utility model relates to a kind of horizontal drilling kick-off device, belongs in the petroleum exploration and development production recovery of subterranean fluid drilling engineering special tool technical field.
In the prior art, on December 26th, 1996, the patent application of a gentle pipe bit tool of ultra-short radius horizontal drilling usefulness is disclosed, application number is 96249291.4, wherein kick-off device is made up of the flexible drilling pipe of curved shell of elasticity and interior encapsulation thereof, the major defect that exists is the curved shell mechanism of elasticity and processing technology complexity, manufacturing cost height, and difficulty of construction is bigger.
The purpose of this utility model is design in order to overcome defective of the prior art a kind of simple in structure, the ultra-short radius horizontal drilling kick-off device at the bottom of the manufacturing cost.
The purpose of this utility model is achieved in that
The utility model is made up of the flexible drilling pipe of top connection, urceolus and the interior dress thereof that can be connected with helicoid hydraulic motor, wherein urceolus is to be pegged graft mutually by the different pipe pipe nipple of two above diameters that pin connects to be composed in series, be provided with the taper groove at the two ends of pipe pipe nipple, one side has circular trough, in the circular trough of urceolus one side spring is installed; The universal flexible hollow shell that the petal pipe nipple of tubulose that flexible drilling pipe is connected in series by hollow cross axle is formed and the high-pressure rubber pipe and the lower contact of liner thereof are formed, direction by urceolus control deflecting, axle by helicoid hydraulic motor drives the universal flexible hollow shell rotation of adorning in the urceolus, moment of torsion is passed to drill bit carry out the deflecting construction.
The utility model compared with prior art has simple in structure, at the bottom of the manufacturing cost, and advantages such as constructing operation convenience.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1: the utility model assembly structure schematic diagram;
Fig. 2: the utility model outer tube structure schematic diagram;
Among the figure: 1-top connection, 2-alignment bearing, 3-overcoat, 4-interior cover, 5-lower contact;
As shown in Figure 1, the utility model is made up of the flexible drilling pipe 3 of the top connection 1 that can be connected with helicoid hydraulic motor, urceolus 4 and interior dress thereof, wherein urceolus 4 is to be pegged graft mutually by the different pipe pipe nipple of two above diameters that pin connects to be composed in series, see Fig. 2, be provided with the taper groove at the two ends of pipe pipe nipple, one side has circular trough, and spring 2 is installed in the circular trough of urceolus one side; The universal flexible hollow shell that the petal pipe nipple of tubulose that flexible drilling pipe 3 is connected in series by hollow cross axle is formed and the high-pressure rubber pipe and the lower contact of liner thereof are formed, direction by urceolus control deflecting, axle by helicoid hydraulic motor drives the universal flexible hollow shell rotation of adorning in the urceolus, moment of torsion is passed to drill bit carry out the deflecting construction.
