Embodiment Construction

[0014] The technical scheme of the present invention will be further described below in conjunction with accompanying drawing, but should not be construed as limiting the present invention:

[0015] figure 1 It is a structural schematic diagram of the present invention, figure 2 yes figure 1 Top view of the middle bit body, combined with figure 1 , figure 2 As shown, the rotatable hydraulic jet drill bit, the device includes a casing 1, a jet 2 and a drill body 3, the jet 2 and the drill body 3 are located inside the casing 1, the drill body 3 is placed in front of the jet 2, the jet 2 and There are water outlet holes on the drill body 3, and the water outlet holes on the jet 2 and the drill body 3 communicate. The function of the ejector 2 is to provide high-pressure water flow, which is sprayed into the water outlet hole on the drill bit body. The outlet holes on the drill body 3 are divided into straight holes 4 and inclined holes 5. The straight holes 4 are located...

Abstract

The invention relates to a rotatable hydraulic jet drill bit. The rotatable hydraulic jet drill bit comprises a housing, an ejector and a drill bit body; the ejector and the drill bit body are positioned inside the housing; the drill bit body is positioned in front of the ejector; water outlets are formed in the ejector and the drill bit body, and are communicated with one another; the water outlets in the drill bit body comprise a straight hole and a plurality of inclined holes, the straight hole is positioned in the center of the drill bit body, the inclined holes are radially arranged around the straight hole, and are inclined in the tangential direction respectively, and the incline directions of the inclined holes are the same. The rotatable hydraulic jet drill bit utilizes high-pressure water flow to realize jetting of the inclined holes in the drill bit body to exert a rotary force on the drill bit body, so that the drill bit body can realize jetting and clockwise or counterclockwise rotation at the same time; points of strength of jetting are changed continually to prevent water from jetting a plurality of single holes, and the operation is convenient so as to realize the purpose that the hydraulic rotating jetting can be utilized to break rocks.

Description

technical field [0001] The invention belongs to the field of oilfield mechanical equipment and relates to a rotatable hydraulic jet drill bit. Background technique [0002] A horizontal well refers to a well whose inclination angle reaches or is close to 90°, and the wellbore is drilled to a certain length along the horizontal direction. Generally speaking, horizontal wells are suitable for thin oil and gas layers or fractured oil and gas reservoirs, with the purpose of increasing the exposed area of ​​oil and gas layers. Horizontal well drilling technology refers to the directional drilling technology that uses special downhole power tools and measurement-while-drilling instruments to drill a well with an inclination angle of 90° or close to it, and maintains this angle to drill a certain length of well section, including measurement-while-drilling technology. , Wellbore trajectory control technology, wellbore stabilization technology, drilling and completion fluid techno...
