description well drilling equipment used in lowering and cementing of liners. SUBSTANCE: disconnector has a body with lock unit in the form of collet with hooks, coupling funnel and flushing holes. Movable bushing is secured in coupling funnel by means of shearing members. Flushing holes are made in movable bushing and closed from inside by suspended plug member and from outside, by plugs on shearing members. Hooks on collets are made in the form of thread. In the second version, collet internal surface is made in the form of cone. External surface of movable bushing embraced by collet is made in the form of vertical cone. In this case, vertexes of cones are directed towards face of movable bushing with large area. EFFECT: higher reliability, simple in manufacture and operation. 3 cl, 2 dwg
