Concrete, cutting ferrule is fixed on screen casing outer wall by pin.
The utility model additionally provides the application of described bore hole grappling washing type dropper in constructing with completion, during open hole well completion, described bore hole grappling washing type dropper is down to down-hole desired location, after putting in place, flushing fluid enters down-hole by screen casing and interior washing pipe, is discharged by the ring set space between screen casing and the borehole wall; After flushing completes, drop into pressure ball, the internal projecting ring that pressure ball clashes into inner sliding sleeve lower end cuts off shear pin, inner sliding sleeve glides, and the annular groove on inner sliding sleeve is relative with the through hole in top connection, then continues fluid injection pressurization, liquid applies pressure to slip ring by the through hole on inner sliding sleeve by the through hole in top connection and screen casing, slip ring and lower slip ring descending, Ka Ya is engaged with the unidirectional tooth of seating nipple lower end, cutting ferrule open hang with the open hole well borehole wall on; Move in the space that the annular groove of ball on inner sliding sleeve and the through hole in top connection limit, liquid enters in above-mentioned limited space, along with residing for ball, space to be narrowed towards the direction of screen casing and is being impacted towards inner sliding sleeve direction ball, on put on joint, ball enters in the annular groove space between top connection and inner sliding sleeve, be connected together by ball between top connection and inner sliding sleeve, joint is put in continuation, top connection, ball, interior washing pipe are up in the lump, and screen casing, cutting ferrule, lower slip ring, seating nipple, slip ring, card tooth, torsion head hang with in well.
The utility model has following technical advantage:
1, cutting ferrule design is unique, makes small tools instrument can realize hanging in large pit shaft, as 90mm instrument can rivet in 130mm well.
2, screen casing and interior washing pipe are gone into the well in the lump and are carried out flushing operation, avoid first to rinse to cause well expanding, more lower screen casing, cause construction often not do over again smoothly, the consequence that time serious, well is scrapped.
