Embodiment Construction

[0031] It should be noted that, in the case of no conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0032] Combine below Figure 1 to Figure 6 , the preferred embodiments of the present invention will be described in further detail.

[0033] Such as figure 1 As shown, the section of the rotary steerable tool with a bag along the axis of the drill string 3 is described.

[0034] The protrusion 14 is fixedly connected to one side of the outer circumference of the front end of the outer cylinder 10. When the outer cylinder 10 is laterally stationary relative to the well wall through friction, the protrusion 14 pushes against the corresponding well wall, so that the drill bit 4 is biased to the opposite well wall. Thereby strengthen the unilateral cutting of drill bit 4, to realize gui...

Abstract

The invention relates to a drilling tool in the field of oil, natural gas and other drilling, and is a rotary steering tool with a bag. Technical problem: the existing tool has complex structure, many internal cavities and is not compact. Technical solution: a protrusion is fixedly connected to the outer periphery of the tool to push against the well wall. Technical features: including mandrel, outer cylinder, base, protrusion; the rear end of the base is fixedly connected to the drill string; the base is fixedly connected to the mandrel, and the front end of the mandrel is fixedly connected to the drill bit; the rear end of the outer cylinder is rotatably socketed on the On the base, the front end of the outer cylinder is rotatably sleeved on the mandrel; the protrusion is fixedly connected to one side of the outer periphery of the front end of the outer cylinder. Beneficial effects: one side of the outer cylinder is fixedly connected with a protrusion, which can cause the drill bit to tilt to the opposite well wall, thereby increasing the unilateral cutting of the drill bit and achieving the effect of deflection; this scheme has a compact structure and fewer internal cavities , which is beneficial to reduce the requirements for materials and improve the working life of rotary steerable tools.

Description

technical field [0001] The invention relates to a drilling tool in the field of oil, natural gas and other drilling, and is a rotary steering tool with a bag. Background technique [0002] In the prior art, there are mainly two types of rotary steerable drilling tools: push-by type and point-to-point type. Among them, the push-to-type rotary steerable drilling tool is equipped with three retractable ribs evenly on the outer periphery of the tool, and the three ribs can be selectively pushed against the well wall in the set direction, causing the bit to deviate, thereby increasing the single-piece of the drill bit. Cutting on the side, realize the control of the drilling direction of the drill bit, and achieve the purpose of steering; however, the volume, especially the radius, of the steering drilling tool is limited, and the three retractable ribs make the structure complex and the internal cavity is large , high requirements on materials. [0003] The pointing rotary ste...
