Description
Technical field:
The utility model relates to the corollary apparatus of a kind of oil, gas drilling, particularly a kind of vertical drilling tool.
Background technology:
At present, in drilling process, realize that the deviation prevention and fast on high steep stratum is a ubiquitous technical difficult problem.Domestic existing deviation prevention and fast technology is to utilize tower drilling tool, meet the eye on every side hold angle drilling tool, pendulum assembly, decentralized drill collar or off-axis and carry out deviation prevention and fast, yet these technology are the deviation prevention and fast that cost realizes high steep stratum to sacrifice the pressure of the drill, to reduce rate of penetration mostly.The hole deviation problem on stratum such as solution high inclination-angle that therefore can not economical and efficient, steep structure, and cause problem such as lock of tool drilling easily.
The utility model content:
The technical problems to be solved in the utility model provides a kind of vertical drilling tool, this vertical drilling tool has been realized can be when skew takes place in well, automatically the flash in well produces a thrust, under the reaction force of the borehole wall, increase the cutting output of drill bit on the low limit of well, drill bit is remained to vertical direction creep into, thereby reach the purpose of drop angle.Having overcome prior art is the deficiency that cost realizes the deviation prevention and fast on high steep stratum to sacrifice the pressure of the drill, to reduce rate of penetration mostly.
Technical solution adopted in the utility model is: a kind of vertical drilling tool, and stablize piece, rib and lower contact and form by top connection, turbine generator, positioning tube, voltage rectifier, tool body, acceleration of gravity meter, centralizer, central controller, gland, fuel tank, hydraulic pump, motor, plunger displacement pump, interior six rib nuts, rib; Turbine generator is installed in the positioning tube, positioning tube is fixed on the tool body inwall, turbine generator links to each other with voltage rectifier, between voltage rectifier and the acceleration of gravity meter, between acceleration of gravity meter and the central controller centralizer is installed all, gland seal fuel tank, hydraulic pump, motor, plunger displacement pump are in tool body inside, rib is stablized piece and is fixed on the tool body, and rib is connected with plunger displacement pump.
The groove milling of described tool body upper surface institute is 3, is distributed on the same circumference of tool body, and corresponding plunger displacement pump is 3.
It is to be fixed on the tool body with interior six rib nuts that described rib is stablized piece.
The beneficial effects of the utility model are: the utility model is owing to adopted turbine generator to be installed in the positioning tube, positioning tube is fixed on the tool body inwall, turbine generator links to each other with voltage rectifier, between voltage rectifier and acceleration of gravity meter, centralizer all is installed between acceleration of gravity meter and the central controller, the gland seal fuel tank, hydraulic pump, motor, plunger displacement pump is in tool body inside, rib is stablized piece and is fixed on the tool body, the structure that rib is connected with plunger displacement pump, thereby have can be when skew takes place in well, automatically the flash in well produces a thrust, under the reaction force of the borehole wall, increase the cutting output of drill bit, make drill bit remain the function of creeping into to vertical direction on the low limit of well.In addition, the utility model is dynamic bias backup bit system, and is simple and practical, esy to use, safe and reliable, press consumption to hang down and be applicable to multiple offshore boring island, do not have relative stationary part with well, help the cleaning of well, make well Paint Gloss, frictional force and resistance are little, help the pressure of the drill and directly be added on the drill bit, improve bit speed, reduce drilling cost.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of vertical drilling tool is stablized piece 15, rib 16 and lower contact 17 and is formed by top connection 1, turbine generator 2, positioning tube 3, voltage rectifier 4, tool body 5, acceleration of gravity meter 6, centralizer 7, central controller 8, gland 9, fuel tank 10, hydraulic pump 11, motor 12, plunger displacement pump 13, interior six rib nuts 14, rib.Top connection 1 directly is connected with drill string, transmits the drill string moment of torsion and drives the utility model and drill bit rotary drilling.Turbine generator 2 is installed in the positioning tube 3, positioning tube 3 is fixed on tool body 5 inwalls, turbine generator 2 links to each other with voltage rectifier 4, and the current commutates one-tenth of turbine generator 2 is stablized direct current, electric current supply acceleration of gravity meter 6, central controller 8 and motor 12.Between voltage rectifier 4 and the acceleration of gravity meter 6, between acceleration of gravity meter 6 and the central controller 8 centralizer 7 is installed all, thereby reduce the influence of vibrations to Instrument measuring precision.Acceleration of gravity meter 6 is measured the variation of hole deviation in the drilling process in good time, measured value directly is sent to central controller 8, when measuring hole deviation above setting value, 12 work of central controller 8 control motors, utilize hydraulic pump 11 to extract hydraulic oil from fuel tank 10 and suppress to plunger displacement pump 13, drive rib 16 and stretch out, its reaction force acts is on drill bit, increase the cutting output of drill bit, guarantee the vertical of well track on the low limit of well.Gland 9 leakproof fuel cells 10, hydraulic pump 11, motor 12, plunger displacement pump 13 prevent that in tool body 5 inside the mud in the well from entering.Rib is stablized the interior six rib nuts 14 of piece 15 usefulness and is fixed on the tool body 5, avoids rib 16 to break away under down hole problem, brings difficulty to construction.Rib 16 is connected with plunger displacement pump 13.The groove milling of tool body 5 upper surfaces institute is 3, is distributed on the same circumference of tool body 5, and corresponding plunger displacement pump 13 is 3.
When skew took place well track, the utility model produced a thrust at the flash of well automatically, and under the reaction force of the borehole wall, the increase drill bit remains to vertical direction drill bit and creeps in the cutting output on the low limit of well, thereby reached the purpose of drop angle.
