Urceolus (4) is one and is enclosed within the outer steel cylinder of drilling tool that the internal diameter of urceolus (4) is bigger than drilling tool male joint (2) reinforcement external diameter; Suspension step (3) outer rim is processed with screw thread (901); Urceolus (4) is connected fixing through screw thread (902) with suspension step (3);
Urceolus lower surface (11) is the most beneath end of urceolus (4); Keep certain distance between the reinforcement of the step (10) of urceolus lower surface (11) and drilling tool male joint, that is to say when reserving whole device is connected button with down-hole equipment and detain occlusal position on the tong;
Be the annular space (8) between urceolus and the drilling tool body between drilling tool body surface (7) and urceolus (4) inner surface;
Side pinger interface (5) is near urceolus (4) top and the interface opened in urceolus (4) outside;
Circular bead surface pinger interface (6) is the interface of opening from suspension step (3);
The two is connected side pinger interface (5) and circular bead surface pinger interface (6) with pinger simultaneously, perhaps stops up firmly one of them with plug and only stays another and be connected with pinger.
Said suspension step (3) is straight step or sloping platform rank.
Said drilling tool female joint (1) all is all identical with the joint dimension type of down-hole equipment with drilling tool male joint (2).
The distance of said side pinger interface (5) to urceolus lower surface (11) must be more than or equal to the distance of the envelope core of first shut-in well below rig floor face to the rig floor face mouthful.
The beneficial effect of the utility model is: no matter the down-hole has or not drilling tool; Below the envelope core position of getting into first blowout preventer below the rig floor face under the said joint of the utility model; Close first blowout preventer (also can have nothing to do with), all can solve the problem that pinger can't couple together with well head; Solve when other position is not with the pinger connecting interface on the well head can't monitor well under the problem of level.After increasing the said linkage of the utility model, can be up and down by this device, do not influence the wellhead shut-in sealing, from then on the junction is the linkage between a kind of pinger safely and effectively and well head to down-hole conduct acoustic waves signal again.
