Abstract

The utility model relates to an antifriction and twisting reducing tool for well drilling of a directional well. The technical scheme is as follows: the antifriction and twisting reducing tool comprises an upper connector, a body, balls and a lower connector, wherein the upper connector is sequentially connected with the body and the lower connector; the body is provided with the balls, a pressing plate and a countersunk head bolt; the body is composed of a plurality of convex spiral type structures; each convex spiral type structure is provided with at least one row of the balls. The antifriction and twisting reducing tool is simple in technical design, advanced in functions and good in integrality; friction resistance for moving a drilling tool up and down and tripping by a large displacement well and a rotary torque of a drilling column are greatly reduced; the drilling speed of the large displacement directional well is accelerated and the supporting pressure of directional drilling is relieved; the operation is stable; the antifriction and twisting reducing tool has the characteristics of accuracy and flexibility in control, safety and environmental friendliness, time saving and labor saving, easiness for grasping, high efficiency and the like, and is mainly applied to a drilling process of the large displacement well.

Description

Antifriction lowers for directional well drilling is turned round instrument
Technical field
The utility model relates to a kind of oil drilling tool, and particularly a kind of antifriction lowers for directional well drilling is turned round instrument.
Background technology
At present, there is a kind of oil drilling tool, its structure is axis to be only installed on body or longitudinal roller is only installed, for oil drilling technique contributes, but it exists following shortcoming or deficiency: 1. structure function is single simultaneously, maybe can only reduce the frictional resistance of spudding up and down, maybe can only reduce the driving torque of drill string, and can not both reduce the frictional resistance making a trip simultaneously, reduce again the driving torque of drill string; 2. the bearing in roller is easily stuck, loses effect; 3. be subject to size restrictions, the shaft diameter of roller is little, and intensity is low, the fragile trouble of lost tool in hole that causes.
Chinese patent literature number is 2639507, patent name is that < < extended reach well drilling subtracts and turns round device > > with drilling rod, belong to and beat high angle hole, the drilling well aid using when directional well or extended reach well, the utility model is by mandrel, cutting ferrule and overcoat form, on mandrel, be reserved with bearing groove, overcoat can be arranged on mandrel and be covered bearing groove by cutting ferrule, tourelle is installed in bearing groove, tourelle is rolling bearing assembly, rolling bearing has two groups, for bearing the axial force causing because of friction, preferential contact sleeve inside pipe wall or the borehole wall form and support.Utilize originally to subtract and turn round device and can reduce drilling rod and contact with the direct of internal surface of sleeve pipe or the borehole wall, therefore, drilling rod changes overcoat into sliding-contact between sleeve pipe or the borehole wall and contacts with the rolling between mandrel body, greatly reduced friction torque, reduce the torque consumption of drilling rod, reach the object that improves bit rock breaking capacity.But its problem still existing is: complex structure, cost of manufacture is high, is not widely applied.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of antifriction lowers for directional well drilling to turn round instrument, adopts the structure of on body, free ball being installed, and has both reduced the petty wiping resistance making a trip, and reduces again the driving torque of drill string.
Its technical scheme is: comprise top connection, body, ball and lower contact, top connection is connected with body and lower contact in turn, ball, pressing plate and countersunk bolt are installed on body, described body is the sped structure of a plurality of protrusions, and at least one row's ball is installed on the sped structure of each protrusion.
Above-mentioned body is that the sped structure of three protrusions forms, and row's ball is installed on the sped structure of each protrusion.
Above-mentioned sped structure is fixed by pressing plate and countersunk bolt.
Between above-mentioned a plurality of sped structures, be provided with spiral groove.
The ball of installing on the sped structure protruding rolls and coordinates with tube wall inner chamber.
Above-mentioned top connection is female joint, and lower contact is male joint.
The utility model compared with prior art tool has the following advantages:
1, technical design is simple, and function is advanced, good integrity;
2, greatly reduce the frictional resistance making a trip of extended reach directional well and the driving torque of drill string, accelerate the rate of penetration of extended reach directional well;
3, the backing pressure in the time of can alleviating directional drilling;
4, smooth operation, precise control flexibly, safety and environmental protection, time saving and energy saving, be easy to grasp, efficiency is high.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is A-A sectional views of the present utility model;
In upper figure: top connection 1, body 2, pressing plate 3, ball 4, countersunk bolt 5, lower contact 6, spiral groove 7.
The specific embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises top connection 1, body 2, ball 4 and lower contact 6, top connection 1 is connected with body 2 and lower contact 6 in turn, ball 4, pressing plate 3 and countersunk bolt 5 are installed on body 2, the sped structure that described body 2 is a plurality of protrusions is provided with at least one row's ball 4 on the sped structure of each protrusion.
Wherein, body 2 is that the sped structure of three protrusions forms, and row's ball 4 is installed on the sped structure of each protrusion; Above-mentioned sped structure is fixing by pressing plate 3 and countersunk bolt 5; Between above-mentioned a plurality of sped structures, be provided with spiral groove 7.The ball 4 of installing on the sped structure protruding rolls and coordinates with tube wall inner chamber.Above-mentioned top connection 1 is female joint, and lower contact 6 is male joint.
The utility model is in when operation, and ball 4 is flexible rotating up and down, the frictional resistance when overcoming or alleviate spudding up and down or make a trip and the driving torque of drill string.
The utlity model has technical design simple, function is advanced, good integrity, greatly reduce the driving torque of extended reach well spudding up and down and the frictional resistance making a trip and drill string, accelerate the rate of penetration of extended reach directional well, backing pressure, smooth operation while alleviating directional drilling, precise control flexibly, safety and environmental protection, time saving and energy saving, be easy to grasp, efficiency high, mainly in the drilling technology of extended reach well, apply.
