Abstract
The utility model discloses a self-control type hydraulic reamer which comprises an outer sleeve which is formed by connecting an upper connector (1), a cutter frame body (5) and a lower connector (9) sequentially; a group of rectangular grooves (10) are formed in the cutter frame body (5) along the circumference; through grooves (11) are formed in the lower parts of the rectangular grooves; bottom surfaces of the upper parts of the rectangular grooves are inclined surfaces (12); a mandrel (4) is arranged in the outer sleeve; and a cutter body (6) is arranged on the mandrel (4) and stretches out from the through grooves (11) in the lower parts of the rectangular grooves. According to the self-control type hydraulic reamer, the rectangular grooves on the cutter frame body are ingeniously designed into special-shaped grooves with the through grooves formed in the lower parts and the inclined bottoms at the upper parts. When the self-control type hydraulic reamer is placed into a well, the pressure of a slurry (drilling fluid) inside the well is controlled, so that the mandrel is pushed to overcome a spring force and move upwards, and the cutter body on the mandrel can be unfolded automatically with the rotation of the inclined bottoms of the rectangular grooves in the cutter frame body. In a rotation process of a drill column, a blade on the cutter body starts cutting a rock stratum, and a reaming purpose is achieved. The self-control type hydraulic reamer is simple in structure, easy to process and low in manufacturing cost.

The technical solution of the utility model:
A kind of hydraulic pressure autocontrol reamer comprises the outer tube that is threaded successively and is constituted by top connection, tool holder body and lower contact; Tool holder body is uniformly distributed with one group of rectangular channel along the circumference; The rectangular channel bottom is groove, and the bottom surface on rectangular channel top is the inclined-plane; Be provided with axle in the outer tube, axle is provided with cutter hub, and cutter hub stretches out along the inclined-plane from the groove of rectangular channel bottom.
In the aforementioned hydraulic autocontrol reamer, described axle is tubulose, and the cylindrical of axle is respectively path section, middle footpath section and big footpath section from top to bottom, and middle footpath Duan Yuda footpath section is conical surface transition, and the conical surface is provided with nozzle.
In the aforementioned hydraulic autocontrol reamer, be with spring on the path section of described axle, be provided with spring pad between the middle footpath section end face of spring and axle.
In the aforementioned hydraulic autocontrol reamer, described spring and spring pad cooperate with the intersegmental crack of the path of axle.
In the aforementioned hydraulic autocontrol reamer, the middle footpath section of the described axle position corresponding with rectangular channel bottom groove on the tool holder body is provided with attachment lug, and attachment lug is hinged through rotational pin and cutter hub.
Compared with prior art, it is groove that the utility model is designed to the rectangular channel on the tool holder body bottom cleverly, and top is the special-shaped groove of wedged bottom.After the autocontrol reamer was put into the down-hole, when promoting axle and overcome spring force and move up by the mud in the control well (drilling fluid) pressure, the cutter hub on the axle can open with the wedged bottom of rectangular channel on the tool holder body is rotational automatic.Drill string blade on the cutter hub in rotary course begins to cut the rock stratum, reaches the reaming purpose.The utility model is simple in structure, easily processing, low cost of manufacture.
