Abstract
The utility model discloses a screw rod drilling tool for oil drilling, the screw rod that has the cavity in the middle of one, the bottom fixedly connected with drill tip of screw rod, the upper portion fixedly connected with helical blade of drill tip, the last one -level reaming wing of making with polycrystalline diamond that is provided with of helical blade, the position that is close to one -level reaming wing top on the screw rod is provided with second grade reaming device, in operation, at first bore through the drill tip and move, and simultaneously, one -level reaming wing carries out the reaming, when the reaming is proceeded to needs, pour into the water under high pressure through the governor pump gear into to the store water intracavity, it outwards expands to utilize pressure differential to promote the movable wing of piston drive, simultaneously under the drive of screw rod, integral rotary, carry out reaming work, after the reaming finishes, the rethread reduces the pumping pressure and withdraws movable wing, can avoid the loaded down with trivial details trip -out process in tool joint like this, and the time is saved, moreover, the steam generator is simple in structure, and the production cost is greatly decreased. Shorten the duration of a project, economic benefits is showing by a wide margin.
Description
Technical field
This utility model relates to a kind of drilling tool for oil and gas well drilling, particularly relates to a kind of petroleum drilling and mining helicoid hydraulic motor, belongs to oil drilling and extracting equipment field.
Background technology
Along with the development of petroleum natural gas exploration technology, drilling technology, directional well, being increasingly widely applied from drilling technologies such as formula well, horizontal wells, in drilling process, using reaming tool is comparatively effective technological means. Reaming tool is divided into two classes, and the first kind is fixed, the similar regulator of fixed reamer, can effectively cut the borehole wall, play the effect of gauge in continuing the process crept into, if but pull out of hole time top well section hole shrinkage, lock of tool drilling can be caused. Equations of The Second Kind is expanding reamer, and its feature is to realize expansion and the contraction of wing by regulating pump pressure, and wing can make it open maximum outside diameter equal to bit diameter through special design, and replaceable. But currently used reamer mostly adopts import equipment, and structure is complex, and use cost is higher.
Utility model content
Problem to be solved in the utility model is to provide a kind of simple in construction, can reduce the petroleum drilling and mining helicoid hydraulic motor of production cost.
In order to solve the problems referred to above, this utility model by the following technical solutions:
A kind of petroleum drilling and mining helicoid hydraulic motor, including a middle screw rod with cavity, the bottom of described screw rod is fixedly connected with apex point, the top of described apex point is fixedly connected with helical blade, being provided with the one-level reaming wing made with polycrystalline diamond on described helical blade, on described screw rod, the position above one-level reaming wing is provided with secondary chambering device.
The following is this utility model further optimization to such scheme:
Described secondary chambering device includes the reaming pedestal being fixed on screw rod, and the part that described reaming pedestal is positioned at screw rod has reservoir, and described reservoir can pass through water injection pipe and connect with regulating pump.
Optimize further: the periphery of described reaming pedestal is provided with several compression chambers that can connect with reservoir, it is respectively arranged with piston in described compression chamber, described piston 7 is connected to piston rod, the end of each piston rod is stretched out from the periphery of reaming pedestal and is fixedly connected with movable wing, when each piston rod is under the effect of power, when all stretching out, the round diameter that each movable wing surrounds is more than the diameter of section of helical blade.
During work, first pass through apex point and bore dynamic, simultaneously, one-level reaming wing carries out reaming, when needs proceed reaming, injects water under high pressure by regulating pump in reservoir, pressure reduction is utilized to promote the movable wing of piston driving to expand outwardly, simultaneously under the drive of screw rod, integral-rotation, carry out reaming work, after reaming, regain movable wing again through reducing pump pressure, so can avoid the loaded down with trivial details trip-out process in drilling process, the saving time, simple in construction, greatly reduce production cost. Significantly shorten the duration of a project, remarkable in economical benefits.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
