Abstract
The utility model relates to the field of oil production engineering in oil fields, and belongs to a friction reduction device for an underground horizontal drilling machine of an oil-water well, which mainly solves the problem of relatively serious large friction between the prior flexible shaft and an inner surface of an L-shaped central hole of a drilling gun main body in the process of long-time rotation. The device comprises a guiding body (I 1), a wearing part (2), a bearing (3), a guiding body (II 4), a fixing bolt (5), a gland (6) and the drilling gun main body (7), wherein the guiding body (I 1) and the drilling gun main body (7) are fixedly connected through the fixing bolt (5). The device is mainly applicable to oil-water well oil layer pinpoint and deep penetration horizontal borehole, and has the advantages of simple structure, convenient installation and disassembly, and improves the success rate of an underground horizontal drilling hole.
Description
Technical field:
The utility model relates to the oil field technical field of oil production engineering, belongs between a kind of oil-water well down-hole horizontal boring machine " L " type centre bore inner surface and flexible axle to reduce rubbing device.
Background technology:
At present, notification number is in the oil-water well oil layer positioning deep penetration horizontal drilling device of CN101158271, flexible axle is in " L " type centre bore high speed rotary course that bores gun main body, flexible axle is big especially with the friction of " L " type centre bore inner surface that bores gun main body, in long-time rotary course, flexible axle all compares seriously with the wearing and tearing of " L " type centre bore inner surface, has had a strong impact on the operating efficiency of whole system, has reduced the success rate of oil-water well oil layer positioning deep penetration horizontal drilling.In order to overcome existing oil-water well oil layer positioning deep penetration horizontal drilling device, flexible axle is big with the friction of " L " type centre bore inner surface that bores gun main body, in long-time rotary course, flexible axle and the more serious problem of " L " type centre bore inner surface wearing and tearing have been developed the utility model.
Summary of the invention:
The utility model provides and can use deep groove ball bearing boring on " L " type centre bore inner surface of gun main body, and a kind of oil-water well down-hole horizontal boring machine that makes the sliding friction of flexible axle and " L " type centre bore inner surface that bores gun main body change rolling friction into reduces rubbing device.
The technical solution of the utility model is: it is made up of guide way I, consumable accessory, bearing, guide way II, set bolt, gland, brill gun main body, wherein guide way I is connected and fixed by set bolt with the brill gun main body, consumable accessory is connected and fixed by set bolt with the brill gun main body, guide way II is connected and fixed by set bolt with the brill gun main body, gland is connected and fixed by set bolt with the brill gun main body, bearing is installed in the bearing groove that bores gun main body, relies on the bearing groove of guide way II and gland to fix.
Bearing is two kinds of models: a kind of model is 60/22-2Z, and quantity is five covers, is installed in the cylinder-shaped bearing groove of gland and brill gun main body composition, and another kind of model is 61804-2Z, and quantity is seven covers, is installed in to bore in the gun main body circular arc bearing groove.
Gland is a renewal part, and material can be a nylon 1010, also can be polytetrafluoroethylene (PTFE).
Consumable accessory is a renewal part, and material can be 605iMn, also can be 3Cr13.
The utility model compared with the prior art, has following beneficial effect: owing to take such scheme, has simple in structure, installation and removal convenience, reduced the friction of flexible axle with " L " type centre bore inner surface that bores gun main body, improve the operating efficiency of whole system, and improved the success rate of down-hole horizontal boring.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is guide way I 1 of the present utility model and bore gun main body 7 and fixedly connected sectional drawing;
Fig. 3 is consumable accessory 2 of the present utility model and the sectional drawing of fixedlying connected that bores gun main body 7;
Fig. 4 is guide way II 4 of the present utility model and bore gun main body 7 and fixedly connected sectional drawing.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further: the utility model is by guide way I 1, consumable accessory 2, bearing 3, guide way II 4, set bolt 5, gland 6, boring gun main body 7 forms, wherein guide way I 1 is connected and fixed by set bolt 5 with brill gun main body 7, consumable accessory 2 is connected and fixed by set bolt 5 with brill gun main body 7, guide way II 4 is connected and fixed by set bolt 5 with brill gun main body 7, gland 6 is connected and fixed by set bolt 5 with brill gun main body 7, bearing 3 is installed in the bearing groove that bores gun main body 7, relies on the guide way II 4 and the bearing groove of gland 6 to fix.
During on-the-spot the use, with bearing 3 models is 60/22-2Z, quantity is five covers, be installed in the cylinder-shaped bearing groove of gland 6 and brill gun main body 7 compositions, another kind of model is 61804-2Z, and quantity is seven covers, be installed in and bore in the gun main body 7 circular arc bearing grooves, then with guide way II 4 and the bearing groove that bores gun main body 7 to just in time, withhold bearing 3 at guide way II4 and bore in the bearing groove of gun main body 7, fixedly connected good by set bolt 5.When implementing bore operation, with flexible axle and the sliding friction of boring gun main body 7 " L " type central duct place inner surface, change the rolling friction of flexible axle and bearing 3 into, can reduce flexible axle greatly in the friction of boring gun main body 7 " L " type central duct place inner surface by bearing 3.When bearing 3 has wearing and tearing, can change bearing 3.
