Abstract
The utility model relates to a screw drill, which is formed by the orderly connection of a by-pass valve, an equidistant hypocycloid motor, a cardan shaft with a petal type complementary connected structure, a bearing group composed of TC bearings and series bearings and a driving axle. The outer diameter of the screw drill is 216 millimeters. The utility model has the advantages of good sealing effect, high efficiency, low cost and large operation torque; the service life is increased nearly 3 times, and hidden trouble of leakage is eliminated; the utility model is a very ideal tool to drill 121/4' boreholes, the 216 drill (81/2') belongs to an 8'series, the matching of fishing tools is complete, and when accidents occur, the utility model can fish and wells can be avoided being filled.
Description
The utility model belongs to well drilling tool, particularly a kind of helicoid hydraulic motor.
Present existing helicoid hydraulic motor is a kind of novel mud motor, it adopts positive displacement motor, with the drilling fluid is power, produces moment of torsion, is widely used in directional well, from formula well and horizontal drilling, 244mm (95/8 ") and 197mm (73/4 ") are arranged on the specification of drilling tool, but are boring 121/4 " during well, 197 drilling tools seem that horsepower is not enough; and 244 drilling tools cause annular space too small, accidents happened can't salvage.
The purpose of this utility model provides a kind of helicoid hydraulic motor, solves to bore 121/4, and " well reaches safety, reliable, few accident, zero defects.
The purpose of this utility model is achieved in that
A kind of helicoid hydraulic motor, connect to form successively by bypass valve, motor, universal drive shaft, bearing, power transmission shaft, it is characterized in that: motor is equidistant hypocycloid motor, and universal joint is to adopt the complementary structure that connects of petal type, the bearing group that the outer bearing of power transmission shaft is made up of TC bearing and string bearing.
The bearing group that the outer bearing of power transmission shaft is made up of two TC bearings string bearing middle with being clipped in two TC bearings.
The position that universal joint is connected is the structure that adopts three complementary mutually petal types to connect.
The external diameter of drilling tool is 216 millimeters.
The utility model has the advantages that:
This drilling tool is structurally introduced U.S.'s enlightening with present China and is received the drilling tool of (DYNADRILL) production technology manufacturing and have some main different.
1. the motor line style adopts equidistant hypocycloid manufacturing, and enlightening is received technology and adopted circular arc.And the processing of numerical control milling rotor, good sealing effect, efficient height are adopted in processing.
2. universal drive shaft adopts the petal pattern, adopts the processing of digital control wire-electrode cutting technology, adopts the oxyacetylene torch cutting and connect the technology of receiving, and its advantage is:
A, dimensional accuracy height can reach ± 0.001mm
B, otch parallelism are good
C, do not destroy the metallochemistry composition, and structural constituent, for carburizing and quenching lays the first stone
D, smart rugosity can reach
Therefore, the life-span is received technology than U.S. enlightening and improves nearly 2 times.
3. U.S.'s enlightening is received the drilling tool drive mechanism complexity that technology is produced, and has a pair of dowel, and this dowel is burn-on by electric welding, therefore just exists the hidden danger of leakage.This drilling tool driving-shaft assembly has replaced dowel with woodruff key, need not weld, and has therefore eliminated the hidden danger of leaking.
3, this invention product price is than low 3.5 ten thousand yuan of φ 244/cover, and operation torque will improve 30% than 197, " is very desirable instrument during well at brill 121/4 therefore.
216 drilling tools (81/2 ") belong to 8 " series, fishing tool is comprehensive, accident occurs and can salvage and avoid filling out well.
Below in conjunction with description of drawings embodiment:
Fig. 1 is the helicoid hydraulic motor schematic diagram
Fig. 2 is the equidistant hypocycloid motor of a helicoid hydraulic motor sectional view
Fig. 3 is a helicoid hydraulic motor universal joint sectional view
Fig. 4 is that the complementary connection diagram of petal type is launched in the border of universal joint
A kind of helicoid hydraulic motor of called after 5LZ216 helicoid hydraulic motor is connected to form successively by bypass valve 1, motor 8, universal drive shaft 4, bearing, power transmission shaft 7.Motor is equidistant hypocycloid motor, and the section of the engagement cylinder of stator 2 and rotor 3 is equidistant hypocycloid (shown in Figure 2).Universal joint is to adopt the complementary structure that connects of petal type, and the position that universal joint is connected is the structure that adopts three complementary mutually petal types to connect.The bearing group that the outer bearing of (shown in Fig. 3,4) power transmission shaft is made up of TC bearing and string bearing.The bearing group that the outer bearing of power transmission shaft is made up of two TC bearings string bearing middle with being clipped in two TC bearings.The external diameter of drilling tool is 216 millimeters.
Product price of the present invention is than φ 244 low 3.5 ten thousand yuan/covers, and therefore operation torque " is very desirable instrument during well boring 121/4 than φ 197 raisings 30%.
This 216 drilling tools (81/2 ") belong to 8 " series, fishing tool is comprehensive, accident occurs and can salvage and avoid filling out well.
