Abstract
The utility model discloses a jet flow type hydraulic hammer which is connected with a drill. The jet flow type hydraulic hammer comprises an upper joint, an outer cylinder, a jet flow component, a piston cylinder, a piston, a punching hammer, an eight-direction sleeve and a lower joint, multiple spiral-shaped stabilized belts which are arranged at intervals are formed in the periphery direction of a body of the eight-direction sleeve, a passageway is formed between two adjacent stabilized belts, and the outer diameters of the stabilized belts are slightly less than the outer diameter of the drill. The jet flow type hydraulic hammer is simple in structure. The spiral-shaped stabilized belts are arranged on the eight-direction sleeve so as to enhance working stability of the drill, effectively prevent boreholes from declining, and further improve working efficiency of a tool.
Description
Technical field
The utility model relates to a kind of drilling well speed-raising instrument, particularly relates to a kind of jetting type impactor that surges.
Background technology
At present, rotary percussion drilling speed-raising instrument is one of effective drilling speed means, but in directional well, use the surge drilling assembly of impactor of jetting type to make drill bit well deflection easily occur in the course of the work, hindered the surge development of impactor of jetting type.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can reduces that well deflection in engineering is crossed in drilling well, the jetting type that improves the drill bit job stability surges impactor.
For this reason, the technical solution of the utility model is as follows:
A kind of jetting type impactor that surges, it is connected with drill bit, comprise top connection, outer shell, fluidic, piston rod, piston, block stamp, cover and lower contact from all directions, body circumferencial direction at described all directions cover protrudes the spiral helicine stabilized zone that is formed with the setting of a plurality of intervals, form runner between two adjacent stabilized zones, the external diameter in described stabilized zone is slightly less than described outside diameter.
Preferably, the quantity in described stabilized zone is 3～4, and the lead angle in each stabilized zone is 60～70 °.In an embodiment of the present utility model, the length 〉=600mm in stabilized zone, external diameter are 215mm, and the external diameter in stabilized zone is only less than outside diameter 1mm.Certainly, in actual production, can determine as the case may be suitable stabilized zone length and external diameter.
The utility model is simple in structure, with the jetting type impactor well track deflection problem in directional well of surging, has designed all directions cover with the spiral stabilized zone for drilling well, thereby has strengthened the stability of drill bit work, effectively prevented well deflection.This structure can effectively be stablized well track, realize the drill bit steady operation, thereby improve the operating efficiency of instrument.
Description of drawings
Fig. 1 is the surge cross-sectional view of impactor of jetting type of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in the figure, this jetting type impactor that surges comprises top connection 1, outer shell 2, fluidic 3, piston rod 4, piston 5, block stamp 6, overlaps 7 and lower contact 8 from all directions.The circumferencial direction that overlaps 7 bodies from all directions protrudes and is formed with the spiral helicine stabilized zone 9 that a plurality of intervals arrange.The external diameter in stabilized zone 9 is slightly larger than the external diameter of its drill bit that connects.
The quantity in stabilized zone is generally 3～4, and the lead angle in each stabilized zone is 60～70 °.In the present embodiment, the length 〉=600mm in stabilized zone, stabilized zone external diameter are 215mm.
Present technique provide a kind of new jetting type to surge project organization that impactor overlaps has from all directions solved the jetting type impactor that surges and has been applied to drilling tool hole deviation deflection problem in the directional well drilling process, has strengthened the drill bit job stability.
The surge all directions of impactor of this jetting type puts and is provided with the spiral stabilized zone, the external diameter in stabilized zone is smaller than outside diameter, for example, and can only little 1mm, form larger runner between adjacent stabilized zone, that is: be formed with the groove that several distribute along the stabilized zone between the stabilized zone.After connecting drill bit, the effect of rotary steering stabilizer is played in it puts from all directions spiral stabilized zone, can stablize the drilling tool well track in drilling process, raising drill bit job stability.
