Description
Technical field
The invention belongs to drilling equipment field, particularly relate to a kind of reverse circulation drilling device.
Background technology
Most effective in the drilling method of current broken bad ground is the drilling technology using impact rotating to combine with reacting cycle, the mechanism of its broken bad ground: impact energy and rotation energy are passed to reverse circulation drill bit through unit head, reverse circulation swivel by impactor, reverse circulation drill bit carries out high-frequency impact to rock, make catalase, cycle of higher pressure water enters bottom reverse circulation drill bit through reverse circulation drill bit, and cycle of higher pressure water is entrained with rock slag and utilizes reacting cycle deslagging mode to return central passage discharge from magma.Reverse circulation drill bit, reverse circulation swivel, hydraulic impacter are indispensable parts in impact rotating reverse circulation drilling device.
Existing reverse circulation drill bit is when hard formation is holed, and do not need to consider recirculated water leakage problem, boring can be carried out smoothly; And when the bad ground formed containing clay, quicksand, cobble, gravel, erratic boulder etc. is holed, due to chunky shape rock have size inequality, cementing properties poor, loosely organized, change the features such as layer is frequent, soft or hard is greatly different, so fragment can not be stablized stressed in drilling process, easily to roll, produce multiple cutting face, make drilling efficiency low, the hole that easily occurs collapsing, fall the accident such as block and bit freezing; Because broken formation permeability is strong, easily make flushing liquor miss, cause recirculated water to interrupt, boring cannot be carried out, and even occurs the accidents such as water burst; In existing structure circulating water channel with magma returns central passage and is directly communicated with, negative pressure cannot be formed in drill bit region, cause rock slag to discharge difficulty, efficiency of construction is low.
The reverse circulation swivel that drilling apparatus is used, be by recirculated water and rock slag from shaft bottom through the central passage sucking-off bottom surface of drilling tool, water tap, there is following problem in current rig water tap: the bad problem that there is gas leakage spillage of sealing device, often causes recirculated water to interrupt; Structure design is unreasonable, impact energy and rotation energy can not be passed to drilling tool simultaneously, cause drilling efficiency low.
Creep into applied hydraulic impacter and be divided into following two kinds according to the difference of power source: one utilizes wellbore flushing liquid as power source, return spring or valve sliding inertia generation vibration is added with valve, the piston that hydraulic control impacts cylinder produces vibration, piston rod drives jump bit drill hammer to carry out impact rotating drillng operation, the frequency of impact of this structure can not realize continuously adjustabe, and spring dither easily damages, guiding valve is the effect out of hand by the wearing and tearing of the wellbore flushing liquid of height degree of tempering easily; Another kind utilizes hydraulic oil as power source, this drive system and wellbore flushing liquid are isolated, frequency of impact is generally determined by pilot operated directional control valve and hydraulic system pressure, this structural impact frequency adjustment structure is complicated, and difficulty of processing is high, and frequency of impact adjustable range is little, and the adjustment of fixed frequency can only be realized, but borehole formation is ever-changing, the impact force needed for different stratum is different with frequency, and this hydraulical impact system scope of application is little.
