Background technology
Oil have the title of " blood of World Economics ", always has very important effect in the industry and economic development of China, is the mainstay of Chinese national economy.In recent years, Global Oil recessed market, fall to more than 20 dollar from every barrel more than 90 dollars, but cost of winning increases year by year, along with the exhaustion day by day of China's Shallow Oil-Gas resource, oil-gas mining is inevitable to be developed to deeper, more hard formation direction.When traditional rotary drilling mode encounters hard formation, drilling efficiency reduces, and it is shorter that bit life becomes, and drilling period is longer, and cost is higher;Therefore being effectively improved drilling rate is the problem being nowadays badly in need of in drilling engineering solving;And seek renewal, more efficient rock-breaking and well-drilling technology, improve bit speed, reduce drilling cost, reduce the urgent demand that the exploration and development cycle is drilling technology development.
Summary of the invention
The purpose of this utility model is: provide a kind of degree of depth that can be effectively improved drill bit wedging rock, improve rate of penetration, weaken torque-on-bit, angular velocity and axial velocity fluctuation simultaneously, reduce drilling tool stress fluctuation simultaneously, thus the high frequency reducing the inefficacy of drilling tool reverses and axial double direction impulse device.
The technical solution of the utility model is:
A kind of high frequency reverses and axial double direction impulse device, including shell, union joint, alignment bearing, turbine wheel shaft, upper hammer and lower hammer, it is characterised in that: the threaded one end of shell is provided with union joint;The other end of shell is provided with lower hammer by end cap and buffering spring slide, by nut, turbine wheel shaft is installed in the shell of lower hammer side, by symmetrically arranged alignment bearing, turbine rotor and stator are installed on the circumference of turbine wheel shaft one end, it is slidably fitted with upper hammer by connecting key on the circumference of the turbine wheel shaft other end, installation base it is provided with on upper hammer, by fixed disk, compression spring is installed on the upper hammer of installation base side, being provided with tup on the end face of installation base opposite side, upper hammer is connected by tup and lower hammer Intermittent Contact.
It is provided with spacing preiection on described lower hammer;Impact boss it is symmetrically arranged with on end face inside spacing preiection.
Described impact boss is domatic boss.
Described turbine wheel shaft middle part radial equipartition has flowing hole.
Described fixed disk is fixing with shell to be connected, and fixed disk is slidably connected with upper hammer.
The beneficial effects of the utility model are:
This high frequency reverses and is symmetrically arranged with impact boss on the lower hammer end face of axial double direction impulse device;Upper hammer often rotates one week and can produce an axial impact force and torsional pulse power, cracks can spread in the contact stress being effectively improved between drill bit and rock and broken hole, thus improve the efficiency of breaking rock of drill bit, solve tradition rotary drilling mode when encountering hard formation, drilling efficiency reduces, bit life shortens, the problem that drilling period length, cost are high;This high frequency reverses and axial double direction impulse device is while improving rate of penetration, effectively reduces torque-on-bit, angular velocity and axial velocity fluctuation, and drilling tool stress fluctuation, thus decreases the inefficacy of drilling tool.With reducing drilling cost, there is positive dissemination to improving drilling efficiency.

Detailed description of the invention
This high frequency reverses and axial double direction impulse device includes shell 1, union joint 2, alignment bearing 3, turbine wheel shaft 4, upper hammer 5 and lower hammer 6.The threaded one end of shell 1 is provided with union joint 2;The other end of shell 1 is slidably fitted with lower hammer 6 by end cap 7 and buffer spring 8.Spacing preiection 9 it is provided with on lower hammer 6;Being symmetrically arranged with 2 impact boss 10 on end face inside spacing preiection 9, impact boss 10 is domatic boss.
Being provided with turbine wheel shaft 4 by nut 11 in the shell 1 of lower hammer 6 side, turbine wheel shaft 4 is multidiameter shaft, and the middle part radial equipartition of turbine wheel shaft 4 has flowing hole 12.By symmetrically arranged alignment bearing 3, turbine rotor 13 and stator 14 are installed on the circumference of turbine wheel shaft 4 one end,
Being slidably fitted with upper hammer 5 by connecting key on the circumference of turbine wheel shaft 4 other end, upper hammer 5 can slide axially on turbine wheel shaft 4, and can rotate with the rotation of turbine wheel shaft 4.Being provided with installation base on upper hammer 5, the upper hammer 5 of installation base side is provided with compression spring 16 by fixed disk 15, the end face of installation base opposite side is provided with tup 17, upper hammer 5 is connected with lower hammer 6 Intermittent Contact by tup 17.
The fixed disk 15 of the torsion of this high frequency and axial double direction impulse device is fixing with shell 1 to be connected, and is slidably connected between fixed disk 15 and upper hammer 5.When this high frequency reverses and axial double direction impulse device works, one end is connected with drill string by union joint 2, and transmits drill string torque;The other end is connected with drill bit by lower hammer 6, and transmits impulsive force.In work process, drilling fluid is by Luo Liukong 12 entrance impulse turbine rotor 13 and stator 14 thus drives turbine wheel shaft 4 to rotate, and then drives upper hammer 5 to rotate.During this, owing to being provided with 2 impact boss 10 on lower hammer 6, and impact boss 10 is domatic boss.(being plane transition between peak and the minimum point of impact boss 10) upper hammer 5 is while rotating with turbine wheel shaft 4, tup 17 on upper hammer 5 helically raises thus to peak operation along the domatic track of impact boss 10, when moving to the track plane peak impacting boss 10 with minimum point drop position, upper hammer 5 falls to clashing into lower hammer 6, is consequently formed axial impact force.
After axial impact completes, upper hammer 5 continues to rotate, and now tup 1 contacts with the track plane of impact boss 10, drives lower hammer 6 to produce moment rotation, thus forms a torsional pulse power.Axial impact force and torsional pulse power that this impacter produces cooperate, the contact stress between drill bit and rock and the cracks can spread in broken hole can be effectively improved, thus improve the efficiency of breaking rock of drill bit, solve tradition rotary drilling mode when encountering hard formation, drilling efficiency reduces, bit life shortens, the problem that drilling period length, cost are high;This impacter, while improving rate of penetration, effectively reduces torque-on-bit, angular velocity and axial velocity fluctuation, and drilling tool stress fluctuation, thus decreases the inefficacy of drilling tool.With reducing drilling cost, there is positive dissemination to improving drilling efficiency.
