Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, this utility model is further elaborated.
As it is shown in figure 1, a kind of novel coiled tubing Full hydraulic while-drilling jarring, it comprises: splined shaft 1；Float fulcrum pin 5, its one end is socketed in outside one end of described splined shaft 1；Poppet shaft 9, its one end is socketed in outside the other end of described float fulcrum pin 5；The axis of guide 12, its one end is socketed in outside the other end of described poppet shaft 9；Spline urceolus 2, it is set in outside described splined shaft 1, is provided with jarring pad 4 between one end of its one end and described float fulcrum pin 5；Float urceolus 3, it is set in outside described float fulcrum pin 5, and its one end is connected with one end of described spline urceolus 2, is provided with float 6 between this float urceolus 3 and float fulcrum pin 5；Valve urceolus 8, it is set in outside described float fulcrum pin 5, poppet shaft 9 and the axis of guide 12, and its one end connects the other end of described float urceolus 3 by one first transition joint 7, and its other end connects a lower contact 14 by one second transition joint 13.
This utility model realizes two-way unfreezing operation by following structure, is provided with metering valve 10 between described poppet shaft 9 and valve urceolus 8, and this metering valve 10 has an endoporus and is set in described poppet shaft 9, is provided with needle 11 in this metering valve 10；On described valve urceolus 8 inwall, the position of corresponding described metering valve 10 is provided with interference section, seals for being formed with the cylindrical of described metering valve 10, i.e. outside seal；Be provided with R shape circular arc chamfering in the position of corresponding described metering valve 10 one end of described poppet shaft 9, as in figure 2 it is shown, under hit time form linear sealing with the bore orifice place of described metering valve 10 one end；One end end face of corresponding described metering valve 10 other end of the described axis of guide 12 is 45 ° of tapered slope inclined-planes, as shown in Figure 3, for forming linear sealing when upper hitting with the bore orifice place of described metering valve 10 other end, i.e. inner sealing, inside and outside all seal after, just only by oil leak hole draining, form the time-lag action that builds the pressure.
In the present embodiment, for the ease of the processing of valve urceolus, described valve urceolus 8 is through-hole form, the diameter 0.01mm less of described through-hole diameter of described interference section.
Operation principle of the present utility model is, need to upwards produce when hitting jarring releasing effect, see state of hitting on Fig. 2, lift up drill string, poppet shaft 9, metering valve 10, the axis of guide 12 moves up, there is part size (namely described interference section) to be slightly smaller than clear size of opening owing to valve urceolus 8 is internal, when metering valve 10 passes through, metering valve 10 cylindrical and valve urceolus 8 interference section are closely cooperated, formed and seal, simultaneously, the 45 degree of conical surfaces in the bore orifice place of metering valve 10 and the axle head of the axis of guide 12 form linear sealing, now hydraulic oil carries out slow draining only by the aperture 11 on metering valve body 10, realize drill string energy storage.When metering valve body 10 by the interference section of valve urceolus 8 constantly, build the pressure oil Condition of Sudden Unloading, discharges drill string energy storage, produces upwards jarring action.When jarring releasing need to be carried out downwards, see and hit state under Fig. 3, transfer drill string, poppet shaft 9, metering valve 10, the axis of guide 12 move down, and metering valve 10 cylindrical and valve urceolus 8 interference section closely cooperate, and are formed and seal, simultaneously, the bore orifice place of metering valve 10 forms linear sealing with the R circular arc chamfering in poppet shaft 9, and now hydraulic oil carries out slow draining only by the aperture 11 on metering valve body 10, it is achieved drill string energy storage.When metering valve body 10 by the interference section of valve urceolus 8 constantly, build the pressure oil Condition of Sudden Unloading, and build the pressure oil Condition of Sudden Unloading, discharges drill string energy storage, produces downward jarring action.
Although content of the present utility model has been made to be discussed in detail already by above preferred embodiment, but it should be appreciated that the description above is not considered as restriction of the present utility model.After those skilled in the art have read foregoing, multiple amendment of the present utility model and replacement all be will be apparent from.Therefore, protection domain of the present utility model should be limited to the appended claims.
