Description
Technical field
The utility model relates to drilling tool technical field, relates in particular to a kind of drilling water forced oscillation device.
Background technology
Oil drilling develops to horizontal well gradually from original directional well at present, because making drilling tool in pressure process, presses close to the downside borehole wall in horizontal drilling process by drilling tool, cause drilling tool to rub in drilling process excessive, have a strong impact on and creep into, even cause the de-pressure of drilling tool can not be pressurized to drill bit.Reduce frictional resistance, reduce conventional drilling lock of tool drilling, the efficiency that increases moving the pressure of the drill, raising conventional drilling is problem in the urgent need to address in current drilling engineering.Research can cause mud pressure size variation while finding drilling tool by mud, thereby causes the vibration of this drilling tool regularity, and then makes drilling tool in drilling process, produce vibration, can reach and reduce the resistance of drilling tool at drilling process, thereby reach the effect that drilling tool raises speed.
Utility model content
The purpose of this utility model is to provide a kind of drilling water forced oscillation device, large to solve the drilling tool frictional resistance that prior art exists, and affects the de-problem of pressing of drilling tool speed and drilling tool.
The utility model solves the technical scheme that its technical problem adopts:
A kind of drilling water forced oscillation device, comprise axial oscillation device mechanism and power assembly, axial oscillation device mechanism comprises joint, dish spring, housing and piston, fitting sleeve is contained in housing rear portion, dish spring is connected between housing and joint, piston is arranged on housing front end, power assembly comprises top connection, stator, rotor, upper valve block, lower disc and lower contact, rotor is arranged on stator interior and can in stator, rotates, stator one end is connected with axial oscillation device mechanism by top connection, the stator other end is connected with drilling tool by lower contact, upper valve block is connected with rotor, lower disc is fixedly connected on the stator interior of valve block below, an eccentric orfice is set on upper valve block, a centre bore is set on lower disc.
Above-mentioned upper valve block and lower disc all adopt carbide alloy to process.
Rotor in above-mentioned power assembly adopts conjugation gerotor structure to be arranged in stator.
Operating principle of the present utility model is in horizontal drilling process, instrument of the present invention is arranged on helicoid hydraulic motor upper end, in the time that drilling mud passes through this tool's power assembly part, power motor produces certain moment of torsion and rotating speed under the pressure of mud, thereby drive the upper valve block of its underpart to be rotated, and lower disc is fixed, in upper valve block rotary course, the eccentric orfice of upper lower disc and centre bore constantly produce to be connected and closes two states, in the time of on-state, mud passes through smoothly, in off position time, thereby mud can not be by making the pressure that top formation of sludge is very large: be advanced into axial oscillation device mechanism on this pressure, thereby impeller-hub produces and shrinks to the in-house dish spring of oscillator, in the time that pressure reduces, dish spring rebounds at the elastic force of itself again, make axial oscillation device mechanism under the effect of power assembly, produce the vibration of certain frequency like this, thereby reach the frictional resistance that reduces drilling process, and reach the effect that improves drilling well operating efficiency.
The beneficial effect of the utility model device is that the rotor by adopting the design of conjugation cycloid provides power, and produce certain frequency of oscillation, axial oscillation device mechanism provides axial oscillation function simultaneously, the upper valve block of power assembly and lower disc mud by time can produce pulse function, like this in horizontal drilling process, the utility model device can produce certain frequency of oscillation, reduces thereby reach the frictional resistance that drilling tool produces in horizontal drilling process, and reaches the effect that improves drilling well operating efficiency.
