Abstract
The utility model provides a hydraulic drilling guide apparatus which is used in oil exploration and well drilling. The utility model mainly comprises a mandrel, a lower sub, a reducing sleeve, a piston body and an anchoring mechanism, wherein the piston body is equipped in the mandrel, and the anchoring mechanism is equipped in the reducing sleeve and is mainly composed of a dowel pin, a fluke, a clamping plate, and a compression spring. The utility mode has the advantages that the design is advanced, the structure is reasonable, the use is convenient and reliable, and the utility model can be used to control the track of the drilled holes in the oil exploration and well drilling.
Description
The utility model relates to a kind of steering tool of oil exploration drilling.
In oil exploration drilling, creep into by predetermined orientation in order to make well track, often need the drilling guidance instrument.The reducing cover of original drilling guidance device be by rudder plate and the borehole wall near the frictional resistance that overcomes between reducing cover and the axle, reach thus that drill string drives that axle is rotated and purpose that the reducing cover can not rotate.Above-mentioned rudder plate is embedded in reducing and puts, and does not have any controlling organization, only depend on rotate drill string make it with the borehole wall near, so it is unreliable to work, on put when putting drill string and may cause blocked portion.
The purpose of this utility model is to overcome the problems referred to above, for hole trajectory control provides a kind of hydraulic drilling guider, and not only control easily, and also safe and reliable.
In order to achieve the above object, the utility model is provided with piston body in axle, and its upper and lower side is equipped with sealing and lower seal respectively, between piston body and axle, stage clip can be housed, and also can not adorn, and automatically resets in order to make the piston physical efficiency, and stage clip preferably is housed.Put at reducing of the present utility model and to be equipped with several anchor mechanisms, this mechanism mainly is made of several pins, sealing, anchor fluke, the available leaf spring control of the contraction of anchor fluke, also available pressing plate and stage clip control, for easy to assembly, the most handy pressing plate and stage clip control, its center platen is screwed at reducing and puts.The azimuth mechanism of turning round of the present utility model is assembled into by small pressure spring, backing pin and interstage sleeve, and wherein interstage sleeve is fixed on the axle.
Advantage of the present utility model is that the flexible of anchor fluke can be by fluid power and stage clip control, and easy to operate.
Fig. 1 partly cuts open structural representation for the utility model.
Fig. 2 is an A-A sectional structure schematic diagram among Fig. 1.
Among Fig. 1 and Fig. 2 in number table be shown: 1---piston body, 2---the reducing cover, 3---thrust bearing, 4---spacer, 5---journal bearing, 6---pressing plate, 7---stage clip, 8---anchor fluke, 9---sealing, 10---pin, 11---external seal, 12---axle, 13---lower contact, 14---backing pin, 15---interstage sleeve, 16---small pressure spring, 17---go up sealing, 18---stage clip, 19---lower seal.
Below in conjunction with figure the utility model is described further, referring to Fig. 1 and Fig. 2.Piston body (1) is housed in the axle of the present utility model (12), and sealing (17) is equipped with in the upper end of piston body, and the lower end is equipped with lower seal (19), between piston body (1) and axle (12) stage clip (18) is housed.Be provided with several anchor mechanisms on reducing cover (2), this mechanism is assembled by several pins (10), sealing (9), anchor fluke (8), stage clip (7) and pressing plate (6), and its center platen (6) is screwed on reducing cover (2).Turn round azimuth mechanism and be made of small pressure spring (16), backing pin (14) and interstage sleeve (15), its middle-grade cover (15) is fixed on the axle (12).During use, axle (12) is connected with drill collar, lower contact (13) is connected with drill bit by crossover sub, rotate counterclockwise axle (12), turning round backing pin (14) in the azimuth mechanism stretches in the skewed slot on the reducing cover (2), thereby reducing cover (2) rotates with axle (12), determines direct bearing thus.Circulating mud, hydraulic oil between piston body (1) and the axle (12), by the annular space between the hole on the axle (12) and reducing cover (2) and axle (12), act on the pin (10), by pin (10) anchor fluke (8) is moved outside reducing cover (2), so that with borehole wall B near, fix determined direct bearing thus, when overcoming axle (12) and rotating to the frictional resistance moment of reducing cover (2), clockwise rotating axle (12) afterwards again creeps into, at this moment backing pin (14) does not rotate and can not drive the reducing cover along the inclined-plane motion of reducing cover (2) skewed slot.Stop axle and rotate, and stop mud circulation, at this moment piston body (1) resets under stage clip (18) effect, and pin (10) and anchor fluke (8) also automatically reset under the effect of stage clip (7).
Claims (4)
1, a kind of hydraulic drilling guider that is used for oil exploration drilling, its axle (12) and lower contact (13) are with being threaded togather, reducing cover (2) is contained in outside the axle (12), thrust bearing (3), journal bearing (5), spacer (4) and external seal (11) are housed between them, turning round azimuth mechanism is contained on the axle (12), it is characterized in that in axle of the present utility model, being provided with piston body (1), on reducing cover (2), several anchor mechanisms are housed.
2, hydraulic drilling guider according to claim 1 is characterized in that the described azimuth mechanism of turning round is made of small pressure spring (16), backing pin (14) and interstage sleeve (15), and wherein interstage sleeve (15) is fixed on the axle (12).
