As shown in Fig. 1, Fig. 7, Fig. 8, impacting transmission cylinder 8 tops is that thin cylinder, bottom are thick cylinder; Impact in transmission cylinder 8 and be provided with dark cylinder 87 and lower dark cylinder 89, upper dark cylinder 87 and lower dark cylinder 89 are separated by the flat board 88 at middle part; Thick cylindrical end face is profile of tooth 85, impacts transmission cylinder 8 and realizes staggered cooperation by this profile of tooth 85 with the tooth-shape structure of shell body 2 bottoms; The bottom of lower dark cylinder 89 is provided with drill bit box 86, impacts transmission cylinder 8 and is connected with the pin thread of drill bit by drill bit box 86.
Impact the thin cylindrical both sides excision on transmission cylinder 8 tops, cut position and become drilling fluid runner, the lower end of this drilling fluid runner is communicated with lower dark cylinder by runner breach 83, and drilling fluid enters lower dark cylinder 89 by runner breach 83 by the both sides of impacting transmission cylinder 8, and then flow into drill bit.
Between the thin cylinder of shell body 2 bottoms and impact transmission cylinder 8, be provided with and lift bearing 23 and sealing ring 24.Lift bearing 23 and formed by ball bearing, from the lifting bearing screwed hole and fill in of shell body 2, enter lifting bearing groove and impacting the groove 84 of transmission cylinder of shell body, on bearing pin shutoff shell body 2, lift bearing screwed hole by lifting.Sealing ring 24 is O type circle or the sealing of car formula, is arranged in the sealing ring mounting groove on shell body 2.Lift sealing and integrality that bearing 23 and sealing ring 24 have guaranteed instrument.
Impacting transmission cylinder 8 tops is smooth flat, and by one, fan-shaped and two rectangles form the horizontal profile shape of upper dark cylinder 87, and two rectangles are positioned at the fan-shaped left and right sides, as two ears; All coated with hard alloys polishing smooth of all walls of upper dark cylinder 87; Impact the upper surface of transmission cylinder 8 and the lower surface of jet flow distribution plate 6 and realize sealing by plane jam-packed.
Block stamp 7 is made up of a small cylinder and little fan-shaped cylinder (as shown in Figure 6); The upper and lower end face coated with hard alloy of block stamp 7 also polishes smooth, and two circular arc side coated with hard alloys of block stamp 7 also polish smooth.
As shown in Fig. 1, Fig. 6, block stamp 7 is positioned at dark cylinder 87, and on the Length Ratio of block stamp 7, the degree of depth of dark cylinder 87 is smaller, and block stamp 7 upper surfaces contact with jet flow distribution plate 6 but without compression, and lower surface contacts with flat board 88 but without compression; Upper dark cylinder 87 is divided into left jet chamber 81, right jet chamber 82 by block stamp 7, and left jet chamber 81, right jet chamber 82 communicate with left jet orifice 61, right jet orifice 62 respectively; The smooth abrasion-proof arc surface of block stamp 12 contacts with the wall that impacts dark cylinder 87 on transmission cylinder but without compression; Block stamp 7 can swing in dark cylinder 87 on impact transmission cylinder, and two arcuate profile guarantee can not depart from center in block stamp 7 swing process, and the fluid in swing process in left jet chamber 81, right jet chamber 82 can channelling.
In the time of wellbore construction, jetting type torsional impact drilling tool top is connected on drill collar by top connection 1 upper end box, bottom connects drill bit by the drill bit box 86 that impacts transmission cylinder 8.The pressure of the drill moment of torsion of conventional drilling is delivered to top connection 1 from drill collar and is delivered to shell body 2 again; Again by height rise and fall tooth-shape structure 85 pass to impact transmission cylinder 8, be finally delivered on drill bit.
Drilling fluid enters after top connection 1 inner flow passage, and a part enters the surrounding of valve seat flow distribution plate cylinder 41 and dull and stereotyped 42 both sides, front and back, and a part enters float valve 3 centers becomes jet power fluid.Drilling fluid impacts the upper surface of float valve 3 and hydraulic coupling is delivered to spring 9, mud flow rate is larger, impact force is larger, the decrement of spring 9 is larger, the gap of float valve 3 taper surfaces and top connection 1 taper surface is larger, it is larger that drilling fluid is diverted to flow outside valve seat flow distribution plate cylinder 41, and it is substantially constant to flow into the inner flow that participates in jets acting of float valve 3, and this has just guaranteed normal running parameter and the working life of the substantially constant and percussion tool of the jet parameters of fluidic 5.
Jet drilling fluid enters behind float valve 3 centers, enters fluidic entrance 51 by the dull and stereotyped centre bore of valve seat flow distribution plate 4; Eccentric runner place at fluidic 5 produces one-sided wall-attachment fluidic, and fluidic 5 regulates jet deflection direction automatically according to drilling fluid mobility status and block stamp 8 motion conditions, therefore automatically produces the alternately eccentric jet of deflection of left and right.
Suppose that now eccentric jet flows into jet flow distribution plate 6 left side jet orifices 61 from left avertence heart jet runner 54, then enter and impact the left jet chamber 81 of transmission cylinder 8, fluid enters rear promotion block stamp 7 deflections in left jet chamber 81 and rushes at the wall in right jet chamber 82; The hydraulic pressure fluctuation producing while impacting right jet chamber 82 wall is experienced by fluidic 5, fluidic 5 regulates jet direction to turn to right avertence heart jet runner 55 automatically, eccentric jet enters right side jet orifice 62, then enters the impact right jet of transmission cylinder 8 chamber 82, swings to the left thereby promote block stamp 7; Now left jet chamber 81 inner fluids are discharged by fluidic left bank outlet 52, and the liquid of discharge, with other drilling fluid mixed, finally enters in drill bit by the runner breach 83 and the lower dark cylinder 89 that impact transmission cylinder 8.
When left side cavity 81 inner fluids drain, block stamp 7 collision left side walls, jet direction deflects into left avertence heart jet runner 54 again, left side jet enters the interior promotion block stamp in left jet chamber 81 and starts to swing and discharge right jet chamber 82 interior drilling fluids to the right, then block stamp 12 and the right jet chamber 82 walls impact that bumps.
In this process, block stamp 7 constantly occurs with the left jet chamber 81, the right jet rifle 82 wall collision impacts that impact transmission cylinder 8, constantly left and right conversion of jet direction, block stamp 7 does not stop to swing and produces wall and impacts, the collision impact power producing is constantly delivered to drill bit by impacting transmission cylinder 8, causes fluctuation and the raising of torque-on-bit.
In this instrument drilling process, ground installation, well drilling pipe column, bite type are not had to specific (special) requirements, constructor's operation construction is identical with conventional drilling, is conducive to popularization and the use of instrument.
