Detailed description of the invention
Embodiment 1:
As shown in Figure 1, Figure 2, a kind of rotary guide shoe shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, comprise rotating seat 1 and the leading end 2 being arranged on rotating seat 1 lower end, described leading end 2 is hollow structure, its external surface is provided with multiple blades 9 of the trend that from up to down tilts, and is provided with and unloads discharge orifice 10 towards leading end 2 inside between adjacent blade 9; Leading end 2 inside is provided with the rotary turbine blade 5 that blade seat 13 connects; Blade seat 13 is arranged on this leading end 2 top; The center of described blade seat 13 offers centre bore, the bottom surface of blade seat 13 is provided with the hollow column coaxial with this centre bore, described rotary turbine blade 5 is at least three, and the inner of this rotary turbine blade 5 is connected with hollow column, and the top of rotary turbine blade 5 is connected with blade seat 13; The periphery of blade seat offers at least three through holes 12, and this through hole 12 is placed between adjacent rotary turbine blade 5 respectively.Operating principle of the present invention is: in the decentralization process of sleeve pipe, rotary guide shoe itself has spinfunction, and be hampered when not having drilling fluid to enter passive rotation; When running into larger resistance, by turn on pump pressurized circulation, it is inner that drilling fluid flows into rotary guide shoe by rotating seat 1 endoporus, when flowing through rotary turbine blade 5, reaction force makes blade rotary, blade drives leading end 2 active rotation, and then drive guide shoe head to rotate, thus realize the guiding of sleeve pipe in decentralization process and the function of reaming, also reduce the resistance that casing guide is transferred, ensure that sleeve pipe is lower to shaft bottom smoothly, and liquid is flowed out at a high speed by the discharge orifice 10 that unloads of rotary sleeve guide shoe head end, have and rinse borehole wall function, effectively improve cementing quality.Therefore, the present invention, by increasing rotary turbine blade to traditional guide shoe and tube wall unloads discharge orifice, makes this guide shoe have rotations, guiding function, is applicable to that horizontal segment is long, formation collapse and the more serious exceptional well use of undergauge.
Embodiment 2:
On the basis of embodiment 1, described blade seat 13 is made into integration with leading end 2 or passes through thread connection.The inside wall of described rotating seat 1 lower end is provided with the first ball grooves 7, the lateral wall of leading end 2 upper end is provided with the second ball grooves 8 matched with the first ball grooves 7, rotating seat 1 surface has the pilot hole 11 of the assembling ball leading to the first ball grooves 7 and the second ball grooves 8, contain multiple ball 3 in first ball grooves 7 and the second ball grooves 8, pilot hole is provided with plug 6; Also be provided with sealing ring 4 between rotating seat 1 and leading end 2, sealing ring 4 is positioned at the lower position of the first ball grooves 7 and the second ball grooves 8.
