Изобретение относитс к горной промышленности и может использоватьс в устрой - ствах дл бурени скважин.The invention relates to the mining industry and can be used in drilling equipment.

Известны устройства дл бурени скважин , включающие неотклон емый шнексвый став с установленной в его внутренней полости управл ющей , соединенный гидродомкратом с отклон емьтм ставом, маслонасос с эксцентриковым приводом и реверсивный золотник.Well-drilling devices are known, including a non-steadily screwed end, with a control installed in its internal cavity, a hydraulic jack connected to a deflection stand, an eccentric drive oil pump and a reversing slide.

Однако в таких устройствах отклонение бурового стаза зависит от направлени подачи бурени .However, in such devices, the deflection of the drill stasis depends on the direction of drilling supply.

Цепь изобретени - обеспечить отклонение бурового става,независимо от направленни к глубины бурени .The chain of the invention is to ensure the deviation of the drill rod, regardless of direction to the depth of drilling.

Дл этого в предлагаемом устройстве на наружной поверхности неотклон емого става установлен конусный ползун, соединенный с помощью водила и гайки с управл ю- шей штангой, а реверсивный золотник встроен в шток гидродомкрата и соединен с ползуном толкателем.For this, in the proposed device, a cone-shaped slider is mounted on the outer surface of the non-steerable stand, connected with a carrier and a nut to the control rod, and a reversing slide is integrated into the hydraulic cylinder rod and connected to the slider by a pusher.

Устройство дл бурени скважин (см. чер теж ) имеет два шнековых става - неотклон емый 1 и отклон екшЯ 2, между которыми усть новлен гидродомкрат 3. К наоткдон емохгу ставу 1 гидродомкрат 3 крепитс на подшипниках 4, а к отклон емому 2 - шарнирко В шток 5 гилродомкрата встроены плунжерный насос 6 с нагнета1-елькым и всасыдоюшим клапанами 7 и 8 и рс вечх-ирныП золотник 9. Плунжерный насос 6 и jH.-HepoiBный золотник 9 соединены канала ти. Полость 1О, образованна штоком 5 и внутренним цилиндрок- 11, вл етс полостью пр мого хода, ь п-шость 12 между наружным цилиндром 13 и внутренним 11 об} азует полость об ; атного хода.The device for drilling wells (see drawing) has two screw stands — indispensable 1 and deviating EXT 2, between which a hydraulic jack 3 is installed. To put the hydraulic jack 3, 1 hydraulic jack 3 is mounted on bearings 4, and to deflected 2 it is hinged B The stem 5 of the cylinder is fitted with a plunger pump 6 with an inlet1-oil seal and a suction pressure valve 7 and 8, and a PC valve-valve 9 spool 9. The plunger pump 6 and jH.-HepoiB-valve spool 9 are connected to the tee channel. The cavity 1O formed by the rod 5 and the inner cylinder 11, is a forward stroke cavity, p-width 12 between the outer cylinder 13 and the inner 11, encloses the cavity about; the active course.

На неотклон емом шнековом ставе 1 закреш.ен жестко эксцентриковый кулачок 14, служащий приводом члунж-фног-о насоса 6 ьрн бурении.At the reluctant screw auger 1, a rigidly eccentric cam 14 is driven, which serves as a drive for block-fng pumping of 6 ln drilling.

Claims

The reversing slide 9, which is pressed by the spring 15, is pushed back; scrap 16, which is supported on the cone slider 17.: The cone slider is planted freely on the non-steerable position 1 and lodilas 18, passing through the longitudinal grooves 19 of the non-bendable position 1, is connected to the nut 2O of the control rod 21, of the missed wth Neotlon Art & a. The device works slv overwhelmingly. In case of burenevs, a zherny pump 6, driven by an action with an eccentric cam 14, continuously creates pressure, transferring oil from the cavity 1O and ps 12, or vice versa, the cavity of the IS strips 10, Repeating; supplying the pressure with a rectifier Ik 9, shkhery; EOD5 luchyag suction valve 8 and injected tatepny zshapan 7 to the corresponding posts of hydrocrat 3 .; The reversing slide valve 9 is switched by rotating the control rod 21, which pushes the nut 20. Together with the nut 20, the Body 18 moves along the axis of not turning the auger rod 1 conical slider 17, which through the pusher 16 mixes the reversing slide 9. The drawing shows the situation when The plunger pump into the pumping oil from the cavity 12 into the cavity 10, i.e. the deviation of the ujHOKOBoro 2 from the screw rod 1 is made. Thus, the rotation of the control rod G1 can be performed at any moment of drilling wells, switching the reversing valve 9, i.e. reversing hydraulic jack 3, regardless of the depth and direction of drilling. Formula isbretely Device for well drilling, including rejecting auger stand with a control rod installed in its internal cavity, connected by a hydraulic jack with an adjustable stand, oil jiiacoc with eccentric drive and reverser - - - - - - - - . A strong spool, characterized by the fact that the circuit with the deflecting chain, the drill rod, regardless of the direction of the drilling depth, on the outer surface of the non-locating rod is installed a cone slide that is connected with the aid of a nut and a nut to the control rod, and The reversing spool is built into the brush of the guide rod and is connected to the slide by a pusher.
