Abstract
The utility model relates to a supporting device for an oil and gas well drilling, in particular to a drill accelerator. An upper connector (1) of the drill accelerator is in threaded connection with an internal gear sleeve (2); a planet gear (3) is installed and fixed in the internal gear sleeve (2); the internal gear sleeve (2) is in threaded connection with an accelerator sleeve (8); the accelerator sleeve (8), a bearing sealing sleeve (9) and an accelerator shaft (10) are connected and sealed; and a limit bearing (5), a thrust bearing (6) and a radial bearing (7) are installed among the accelerator sleeve (8), the bearing sealing sleeve (9) and the accelerator shaft (10). The supporting device effectively increases the deep drilling mechanical drilling rate, the loss of working pressure is small, and the device does not increase load to ground equipment and overcomes the deficiency of low drilling rate of the conventional deep drilling machinery.
Description
Technical field:
The utility model relates to the corollary apparatus of a kind of oil, gas drilling, particularly a kind of drill bit accelerator.
Background technology:
Central Asia's oil reservoir generally have bury dark, characteristics such as geological conditions complexity, strata pressure height, drillability difference, thereby when oil field operation, need raise speed to drill bit usually.Conventional speed-raising can only rely on screw rod, and the pressure of screw rod consumption, make this ground installation that can't bear the heavy load be difficult to operate as normal, if and the use drilling rod directly carries out wellbore construction, rate of penetration is very low, be approximately 0.3m/h, this has not only increased drilling period, and has wasted great amount of manpower and material resources.
The utility model content:
The technical problems to be solved in the utility model provides a kind of drill bit accelerator, and this drill bit accelerator has realized that effective raising deep drilling rate of penetration and working pressure loss are little, ground installation is not increased load.Overcome the low deficiency of existing deep drilling rate of penetration.
Technical solution adopted in the utility model is: a kind of drill bit accelerator, form by top connection, inner gear housing, planetary gear, axle sleeve, Limit Bearing, thrust bearing, journal bearing, accelerator cover, bearing seal cover and accelerator shaft; Top connection is threaded with inner gear housing, planetary gear is mounted and fixed in the inner gear housing, and inner gear housing is connected with the accelerator external threading, and the accelerator cover is connected sealing with the bearing seal cover with accelerator shaft, Limit Bearing is installed therebetween, thrust bearing and journal bearing.
The beneficial effects of the utility model are: the utility model is owing to adopted top connection to be threaded with inner gear housing, planetary gear is mounted and fixed in the inner gear housing, inner gear housing is connected with the accelerator external threading, the accelerator cover is connected sealing with the bearing seal cover with accelerator shaft, Limit Bearing is installed therebetween, the structure of thrust bearing and journal bearing, thereby have the effect of effective raising deep drilling rate of penetration; The utility model volume is little, and is simple in structure, good operating stability, and power comes from the rotation of drill string self in the drilling process fully, increases added burden to ground installation.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of drill bit accelerator is made up of top connection 1, inner gear housing 2, planetary gear 3, axle sleeve 4, Limit Bearing 5, thrust bearing 6, journal bearing 7, accelerator cover 8, bearing seal cover 9 and accelerator shaft 10; Top connection 1 is threaded with inner gear housing 2, planetary gear 3 is mounted and fixed on 2 li of inner gear housings, by gears engaged the moment of torsion that drill string rotating produces is passed to accelerator shaft 10, inner gear housing 2 is threaded with accelerator cover 8, accelerator cover 8 and bearing seal are overlapped 9 and are connected sealing with accelerator shaft 10, Limit Bearing 5 is installed therebetween, thrust bearing 6 and journal bearing 7, and fixing with axle sleeve 4.
During the utility model work, the top connection 1 of drill bit accelerator is connected with drilling tool, the bottom directly connects drill bit, normal rotation by the top drilling tool drives 2 rotations of instrument inner gear housing, inner gear housing 2 and planetary gear 3 engaged transmission, owing to have the effect of a gearing factor ratio, thus several times improve the velocity of rotation of accelerator shaft 10, thereby improved the frequency of downhole drill bit cutting rock stratum, finally reached the purpose that improves rate of penetration.
Claims (1)
1. a drill bit accelerator is made up of top connection (1), inner gear housing (2), planetary gear (3), axle sleeve (4), Limit Bearing (5), thrust bearing (6), journal bearing (7), accelerator cover (8), bearing seal cover (9) and accelerator shaft (10); It is characterized in that: top connection (1) is threaded with inner gear housing (2), planetary gear (3) is mounted and fixed on inner gear housing (2) lining, inner gear housing (2) is threaded with accelerator cover (8), accelerator cover (8) is connected sealing with bearing seal cover (9) with accelerator shaft (10), Limit Bearing (5) is installed therebetween, thrust bearing (6) and journal bearing (7).
