Description
Technical field
The utility model relates to the corollary apparatus technical field of oil drilling, relates in particular to a kind of for vibrating the drilling rig of drill string.
Background technology
Utilizing drill string to carry out in the process of oil or gas drilling, contacting and rubbing between drill string and the borehole wall will consume part the pressure of the drill, this phenomenon is along with the difference between head of liquid and strata pressure in the formation of the increase of hole deviation, cutting bed and well and manifest gradually, when serious, drill string, by complete stop motion, causes lock of tool drilling.Therefore, how reducing contacting and friction between drill string and the borehole wall, is that the part weight of upper drilling string is passed to drill bit downwards smoothly, guarantees the key that drill bit efficient rock-breaking creeps into.
In order to solve the problems of the technologies described above, following technology is proposed in prior art:
China Patent No. " 201220358718.4 " discloses a kind of drilling tool that excites drillstring vibrations, its open day is on 02 13rd, 2013, its technical scheme is that described drilling tool comprises: the upper shell of a tubular, the upper end of described upper shell is provided with crossover sub, the slid underneath of described crossover sub is provided with piston rod, the lower end of described upper shell is stretched out in the lower end of described piston rod, and described piston rod is provided with the piston rod runner along its axially extended hollow; The lower house of a tubular, the upper end of described lower house is fixedly connected with the lower end of described piston rod, in described lower house, be provided with the water conservancy diversion drive unit that is positioned at described piston rod below, and be positioned at the moushroom valve device of described water conservancy diversion drive unit below, for periodically connecting or blocking-up drilling fluid.This patent mainly drives Moving plate valve to rotate by drilling fluid, Moving plate valve runner and quiet moushroom valve runner are periodically connected or blocking-up drilling fluid, realize drill string and produce in the axial direction periodic vibration, but in actual use, in the time that drilling fluid is blocked, when Moving plate valve runner turns to while staggering with quiet moushroom valve runner, Moving plate valve top drilling liquid pressure sharply rises, now whole flow guiding head is all arranged in drilling fluid, drilling fluid only has pressure to flow guiding head and without impact force, cause flow guiding head can not drive Moving plate valve to rotate, not only still can not solve the larger problem of frictional force between drill string and the borehole wall, also cause bit speed slow.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, provide a kind of for vibrating the drilling rig of drill string, the utility model makes drill string periodic vibration in the axial direction, and make the vibration number of drill string within each cycle identical, reach the frictional force reducing between drill string and the borehole wall and the object that improves bit speed.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of for vibrating the drilling rig of drill string, comprise the piston rod with runner, tubular upper shell and tubular lower house, piston rod one end is arranged in upper shell, the other end stretches out upper shell, and be fixedly connected with lower house by transition joint, it is characterized in that: described in be positioned at transition joint below lower house be disposed with adapter, flow guiding head, hollow mandrel, with Moving plate valve and the quiet moushroom valve of runner, in described flow guiding head, evenly offer multiple inclination runners, described axle is fixedly connected with integral with flow guiding head with Moving plate valve respectively, and be movably arranged in lower house by bearing, described adapter is fixedly installed between transition joint and flow guiding head, and on adapter, evenly offer multiple vertical runners, in the time rotating under the impact of flow guiding head at drilling fluid, drilling fluid liquid measure by inclination runner periodically reduces, described quiet moushroom valve is fixed on Moving plate valve below, and quiet moushroom valve coordinates with Moving plate valve for periodically connecting or blocking-up drilling fluid.
Between described adapter and flow guiding head, there is the gap of 0.4-1cm.
Employing the utility model has the advantage of:
One, in the utility model, before drilling well, multiple vertical runner on adapter is corresponding with the multiple inclination runners in flow guiding head, now maximum by the drilling fluid liquid measure of inclination runner, when drilling well, flow guiding head is rotated under the impact of drilling fluid, along with the rotation of flow guiding head, inclination runner and vertical runner sequence, now reduce gradually by the drilling fluid liquid measure of inclination runner, in the time misplacing completely with the runner of quiet moushroom valve under the drive in flow guiding head of the runner of Moving plate valve, be that drilling fluid is while being blocked, due to the reason of adapter, flow guiding head can not be soaked in drilling fluid, therefore still can under the impact of drilling fluid, continue to rotate.So go round and begin again, not only make drill string can produce in the axial direction periodic vibration, also make the vibration number of drill string within each cycle identical, effectively reduced the frictional force between drill string and the borehole wall and improved bit speed.
Two, in the utility model, if the gap between adapter and flow guiding head is less than 0.4cm, the impact force that causes drilling fluid is declined, be unfavorable for the rotation of flow guiding head, if and gap between adapter and flow guiding head is greater than 1cm, cause again the drilling liquid pressure hoisting velocity on adapter slower, a little less than making drill string vibration intensity in the axial direction, easily affect bit speed; Therefore the gap between described adapter and flow guiding head is set to 0.4-1cm, under the prerequisite that makes flow guiding head can continue to rotate, has ensured bit speed.
