Abstract
The utility model relates to a rotary guiding tool for oil well drill bits. The rotary guiding drilling tool mainly consists of a guiding sleeve and a mandrel, wherein the mandrel is sleeved with the guiding sleeve; the guiding sleeve is rotationally connected with the mandrel through a bearing; and a plurality of centering wheels as well as a measurement control module and a controllable guiding rib are arranged on the guiding sleeve. The tool is simple in structure and higher in practicability.
Description
Technical field
The utility model relates to a kind of drill for oil well rotary steerable tool.
Background technology
Until the nineties in 20th century, rotary steerable drilling technology as a most advanced and sophisticated automated drilling new technology in the world just true development get up.Rotary steerable drilling system is because downhole tool is worked under rotation status always, wellbore trajectory control accuracy is high, displacement extension ability is strong, effect of hole cleaning is good, be applicable to marine oil and gas development of resources and in the complex reservoir of latter period of oilfield development, bore the special wells such as extended reach well, high-leveled and difficult directional well, cluster well and 3 D complex structure well, at present, drill for oil well steering tool complex structure, the more expensive saving that is unfavorable for cost of production of cost.
Summary of the invention
The utility model is intended to propose a kind of a kind of rotary steerable tool simple in structure, with low cost.
A kind of rotary steering drilling tool described in the utility model, mainly fairlead and mandrel, consist of, fairlead is socketed in mandrel outside, between fairlead and mandrel, by bearing, is rotatedly connected, fairlead is provided with several righting wheels, and is also provided with measurement control module and controlled guiding rib.
The utility model is simple in structure, practical.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
1-fairlead in figure; 2-mandrel; 3-righting wheel.
The specific embodiment
A kind of rotary steerable tool described in the utility model, mainly by fairlead 1 and mandrel 2, formed, fairlead 1 is socketed in mandrel 2 outsides, between fairlead 1 and mandrel 2, by bearing, be rotatedly connected, fairlead 1 is provided with several righting wheels 3, and be also provided with and measure control module and controlled guiding rib, fairlead 1 is fixed in well by centralizer, between fairlead 1 and mandrel 2, by bearing, be connected to form relatively turnable structure, mandrel 2 upper ends connect drill string, lower end connects drill bit, plays a part to transmit the pressure of the drill, moment of torsion, and be the transfer passage of drilling fluid simultaneously; In fairlead 1, be provided with down-hole master cpu, measure control module and controlled guiding rib, sensor is installed in it, can measuring well oblique angle, temperature and pressure and other parameters, and monitor in real time the duty of steering tool.
