Abstract

The invention discloses a kind of high speed broken rock drilling tool of double twisting actions, use hydraulic impact hammer with rotor motor for main powered actuation mechanism, double twisting actions that a kind of high speed broken rock drilling tool of double twisting actions of the present invention is rotated to be by the high speed of the reciprocal high-frequency percussion of hydraulic impact hammer and rotor provide power, ultrahigh rotating speed is provided for drill bit, drill bit is set more efficiently to creep into hard rock, rate of penetration is effectively raised, reduces drilling cost;Since a kind of high speed broken rock drilling tool of double twisting actions of the present invention forms high-frequency, uniform and stable mechanical shock energy and rotation function, drill bit and shaft bottom is set to remain continuous high frequency cutting, improve shear efficiency, the nuisance vibration being likely to occur during drill bit movement is eliminated, is conducive to eliminate stick-slip phenomenon.The present invention enables to drill bit particularly to play good effect in the rock stratum of plasticity so that the use scope of drill bit greatly improves in soft or hard inhomogeneous interlayer staggeredly.

Description

A kind of high speed broken rock drilling tool of double twisting actions
Technical field
The invention belongs to a kind of broken rock drilling tool in the trenchless engineering such as oil-gas drilling, geological drilling field, especially Good effect is played in the rock stratum for being the soft or hard inhomogeneous interlayer and plasticity staggeredly being related in drilling deep wells, ultradeep well A kind of high speed broken rock drilling tool of double twisting actions of fruit.
Background technology
In recent years, as the rapid development of China's economy and oil-gas field development and the continuous of non-renewable resources are decayed, In order to alleviate the situation that China's petroleum resources depends on import unduly, domestic each elephant is accelerated the exploration to petroleum resources and is opened Hair, therefore, petroleum works technical staff start to the geological conditions such as deep-well, ultradeep well are extremely severe and rock drillability pole The stratum of difference carries out the exploitation of petroleum resources, this also allows for drilling mode to diversified development, meanwhile, drilling tool is wanted Ask higher and higher.How improving rate of penetration and reducing drilling cost becomes all drilling technology personnel focus of interest. Substantial amounts of research has been carried out both at home and abroad in order to solve this problem by varying drilling mode and has researched and developed new drilling tool etc., Improve rate of penetration and there is significant effect in terms of reducing drilling cost.But with the hair to deepen continuously of probing industry Open up and to PDC drill bit(Polycrystalline Diamond Compact bit, polycrystalline diamond compact bit)Depth Enter research, compared with other kinds of drill bit, PDC drill bit is by technical advantages such as high rotating speed, high discharge capacity, low the pressure of the drill, small moments of torsion Usage quantity in drilling well is more and more wider, but during use it has been found that during rotary drilling, drill bit exists Contacted under certain the pressure of the drill with stratum, since the movement of PDC drill bit is extremely unordered, including transverse direction, longitudinal direction and torsional direction Vibration and the combination of these types vibration, accordingly, it is possible to the stick-slip of horizontal whirling motion, longitudinal direction bounce and torsional direction occurs, Meanwhile the vibration of underground can damage single PDC cutting tooths, cause the service life reduction of drill bit, it is also possible to disturb oriented control to believe Number and well logging signal and produce irregular borehole, reduce wellbore quality.
Therefore, it is necessary to propose a kind of improvement, the defects of to overcome conventional art.
The content of the invention
In order to improve wellbore quality and rate of penetration, reduction drilling cost and solve to occur in drilling process viscous Phenomena such as cunning, bit freezing, the rock stratum of the soft or hard inhomogeneous interlayer and plasticity staggeredly particularly in drilling deep wells, ultradeep well Hardpan when the PDC drill bit serious wear that occurs, the problems such as service life is short, the present invention provided a kind of double twisting actions High speed broken rock drilling tool.
