Abstract
The utility model discloses a rotary hot melting drill bit. Two independent heating modules and one non-heating module form a round head drill bit, and an outfall is formed at the bottom of the drill bit; when the two heating modules work and the drill bit drills normally in rotation form, because of rotation, the heat of the heating modules can be transferred around evenly, an ice layer is melted, and the drilling is vertical hole drilling operation; when the two heating modules work, and the drill bit feeds in non-rotary form, the ice layer close to the two heating modules continues to melt after absorbing heat, and the ice layer at the side of the non-heating module melts slowly or stops melting, thus the drilling tool is inclined so as to change the hole drilling direction and realize orientation. The rotary hot melting drill bit solves the difficult problem of drilling a directional well in the polar ice layer well, and the drill bit is well compatible to the conventional drilling tools, the directional drill bit can be used just by matching of a control system of the conventional hot melting drilling tool and a drill bit circuit, and the upper mechanical structure is substantially unchanged; and the hot melting drill bit adopts the modular design, and is simple in structure and easy to replace, so that the service life and the utilization rate of the drill bit are increased greatly.
Description
Technical field
The utility model relates to a kind of ice sheet directed drilling of directional well use that creeps at the polar region ice sheet with turning round hot melting drill head.
Background technology
The hot melt drilling tool that uses in the world at present mostly is and creeps into the upright opening use, when main aperture drilling accident occurs and maybe needs out branched hole, then need whipstock at the bottom of the lower hand-hole, and enlarge at the bottom of utilizing special tool(s) with the hole, then be lowered to the hot melt drilling tool, under the help on whipstock inclined-plane, thereby drilling tool tilts to realize that inclined hole creeps into.But adopt this method to creep into inclined hole, drilling tool has the trend to vertical offset all the time under Gravitative Loads, also will return vertical direction after after a while, can not realize that inclined hole creeps into.And along with global warming and going deep into polar ice sheet research, increasing scientists not only is confined to research ice core itself, and begin to pay close attention to the stability of ice sheet self, and such as the ice sheet translational speed in every year, the problems such as discharge that subglacial stream and subglacial lake flow into the sea.The research of these problems also just for drilling technique has proposed new problem, needs a kind of novel drilling tool of not getting the core fast pore-creating and possessing the directional hole construction ability simultaneously.At present in the world the existing drill bit of not getting core hot melt drilling tool all centered by heated type, bore such as the probes I of Germany and the satellite hot melt of probes II and The Hong Kong Polytechnic University's research, such mode of heating can not make drilling tool realize directional drilling.Winconsin-Madison university has developed the directed drilling tool of a kind of motor machine, is that the opening width that relies on control to be installed in three orientation levers on the drilling tool to apply certain lateral force to drilling tool, thereby makes drilling tool creep into middle change direction.Also do not see the introduction of domestic and foreign literature for the research of the directed drilling tool of hot melt.But it is stronger handling that directed hot melt drilling tool has than motor machine drilling tool, and simple in structure, easily realizes, work also relatively stable, is bound to become the main direction that polar region ice sheet Directional Drilling tool is studied in the research in future.
Summary of the invention
The purpose of this utility model provides the revolution hot melting drill head that a kind of ice sheet directed drilling that can realize directional drilling in the probing of polar region and glacier is used.
The utility model by two independently heating module and one not heating module form, two independently heating module and one not heating module form sphaerocepharous drill bit, the drill bit bottom offers outfall, the suction water pipe of top drilling tool drainage pump can be installed near the position mouth of a river, outfall can in time be drained melting water at the bottom of the hole, be conducive to the heat transmission, heating module is the cast copper heater, the side of heating module and inner surface all scribble thermal insulating coating, be conducive to like this heat by external surface to the ice sheet transmission.
The inwall of described heating module has terminal, terminal is connected with wire, and the other end of terminal is connected with the slip ring prap, terminal, wire and slip ring prap, all adopt waterproofing work, described slip ring prap links to each other with power supply from the top drilling tool.
