Description
Technical field
The high frequency torque oscillations device of the utility model relate generally to oil and gas well drilling, CBM Drilling, geological prospecting,
Mine boring tool field.
Background technique
With deepization of national energy strategy implementation, oil and gas well drilling, CBM Drilling, geological prospecting, mine
Drill the deep-well of industry field, ultradeep well, complex structural well exploration and development quantity increasingly increase.In drilling process, with
The increase of well depth, formation hardness is higher and higher, and drillability is deteriorated, and has seriously affected the promotion of mechanical drilling efficiency.Live drilling well
Data shows that the average rate of penetration of deep-well section is only the 15%-30% of upper part well section average rate of penetration, and some areas are even
Lower than 8%.Downhole drilling instrument provide statistics indicate that, in drilling process, due to the work of bit cutting and formation rock
With violent revolving speed and torque ripple can be generated on drill bit, i.e. the sliding vibration of drill chuck.The sliding vibration of card is larger to the harm of drill bit,
Not only Cutter is easily caused to collapse damage, influences bit life, it is serious to reduce drill bit efficiency of breaking rock, but also will cause underground
Tool joint releases, and drilling tool is caused to fall down hole problem.The sliding vibration of drill chuck mainly includes two states: (1) stagnating shape
State, because broken rock torque deficiency stops operating, drill string continues to reverse drill bit under the driving of turntable, when the accumulated energy of drill string is enough brokenly
When detritus layer, drill bit is continued to rotate；(2) high-speed rotation state, the energy abrupt release of drill string savings, drill bit are prominent in both forward and reverse directions
So accelerate and slow down, point angle speed is several times as much as rotary speed, load torque big ups and downs in rock stratum suffered by drill bit.Card slides vibration
The main reason for causing drilling well dysfunction, to mainly influence includes: that (1) increases bit wear, PDC caused by drilling engineering
The movement of drill bit moment high speed impact will accelerate drill bit failure；(2) drill bit disordered motion caused by the sliding vibration of card reduces well drilling and rock crushing
Energy efficiency, the energy that consumption drilling machine down-hole drive device provides；(3) the sliding vibration of card itself and its other caused vibrations are accelerated
Bottomhole assembly fatigue failure or thread gluing, and cause the initial failure of downhole electronics；(4) drilling continuity and well are reduced
Body quality increases rotating hours and the number that makes a trip, and reduces drilling efficiency.In conclusion when deep-well, complex structural well are crept into
The sliding vibration of card is extremely serious on drilling well influence, causes the waste of a large amount of manpower and material resources and cost, how to solve drilling well card
Sliding vibration problem has become the hot spot for falling over each other research and development both at home and abroad.
Research both at home and abroad and live drilling practice prove, apply the high frequency torque oscillations of circumferencial direction on drill bit, can
Effectively inhibit the sliding vibration of drill chuck, and well drilling and rock crushing efficiency can be greatly improved.2000, Canadian Ulterra company made
Cooperate PDC drill bit with Torbuster tool, circumferential pulse torque broken rock applied to drill bit with the frequency of 1000~2400min-1,
The sliding vibration of drill chuck is effectively inhibited, drilling life of bit is extended, extends the PDC drill bit scope of application, greatly improve simultaneously
Rate of penetration is widely used in North America, Asia-Pacific, the Middle East, Africa, can be improved rate of penetration 50%~300%, in
Single drilling depth of even depth well section is up to 3000m, and single drilling depth of deep & ultra-deep well section is up to 1500m.The country is on land and sea
Torbuster tool drilling technology is tested and promoted to upper multiple blocks, achieves good speed-raising in boring deep well hard formation
Effect, rate of penetration increase rate is up to 90%~300%.Domestic more colleges and universities and research unit are all directed to Torbuster tool
Principle is analyzed and researched, and the related tool of development is all substantially approximate with its structural principle, mainly utilizes drilling well liquid energy
Make pendulum reciprocally swinging, circumferentially hits vibration effect to produce on drill bit, such as: CN201810496627.9,
CN201310586179.9、CN201610321016.1、CN201310698227.3、CN201310014444.6、
CN201310108104.X, CN201410306930.X, CN201510166838.2, but find in practical applications, it is this past
Physical pendulum dynamic formula principle can also generate while offer forward direction hits vibration effect and reversely hit vibration effect, and reversely hitting vibration, not only consumption is bored
Well liquid energy, and for inhibit the sliding vibration of drill chuck be it is invalid, be also unfavorable for improving drill bit efficiency of breaking rock, at the same time,
This reciprocating swing type hits vibration principle, and there is also pressures to consume higher disadvantage, so that domestic existing pump equipment is in high negative for a long time
Load state be easy to cause equipment damage, and the tool sizes developed are longer, is not able to satisfy the brill such as directional well, complex structural well
The requirement of well technique, use scope are limited；Therefore domestic associated mechanisms propose the structure that vibration principle is hit in rotation, such as:

CN201610399777.9, by analysis as can be seen that although vibration principle is hit in this rotation improves reciprocating swing type principle
High pressure consumption, but requirement on machining accuracy is more highly difficult big, and components material heat treatment process is complicated, and service life is shorter, therefore
It is not able to satisfy the requirement of domestic drilling technology.
