Technical field
The invention belongs to oil and gas drilling project downhole tool technical fields, relate in particular to a kind of for boring
Complete well repairs the Infinite Cyclic well-flushing tool that can be controlled by Fluid pressure during clean-out service.
Background technique
Leakage and overflow are complex situations in common well in drilling process, in conventional leak stopping and kill-job operation, greatly
Granular lost circulation is easy to damage downhole instrument, while then needing quickly in drilling process such as drilling tool water hole blocking
Establishing bypass circulation prevents complex accident；During big displacement deep-well, ultra-deep well drilling, steady tilted section and horizontal segment are normal
A large amount of cutting bed is deposited, is difficult to clear up in time by conventional small size drilling tool round-robin method, possible card resistance drilling tool or has been influenced
Well quality, it is generally the case that certain flow-disturbing need to be generated by the way of pump impulse, help to clean pit shaft.But for slim-hole
Mud motor and measurement while drilling tool be not able to satisfy pump speed requirement needed for reaching flow-disturbing state, especially in high angle hole
Extreme difficulties are caused with pit shaft high-efficiency cleaning is carried out when horizontal well drilling.Drillng operation personnel generally use short, clean-out service,
More bit change and other washing and cleaning operations etc. solve the problems, such as such.These methods perhaps have certain effect to a certain extent, but
It is to need to consume the plenty of time to make a trip, reduces production efficiency.
The existing mono- ball throwing type Infinite Cyclic valve of patent CN106321013A(, 2017.01.11) disclose a kind of single ball throwing
Formula Infinite Cyclic valve is thrown, mainly includes shell, valve piston, transposition control main body.Shell nozzle, while valve are installed on shell
Door piston and transposition control main body are mounted in shell, it can be achieved that sliding along shell axial direction.Shell, valve piston and indexing
Control body interior opens hole and forms primary fluid flow road, and in the first valve position, valve piston blocks shell nozzle, partition sprue and
The connection of bore hole annulus;In the second valve position, valve piston loses the blocking to shell nozzle, allows fluid to pass through along sprue
It crosses shell nozzle and is transferred to bore hole annulus.Transposition control main body has the control groove track in conjunction with fixed pin, guides valve
Piston is converted between the first valve position and the second valve position.The circulating valve is a kind of liquid stream circulating valve selectively unlocked, is solved
Existing circulating valve opening times limitation needs the problem of the resetting valve that make a trip repeatedly, improves drilling efficiency, shortens drilling well
Time.
A kind of existing underground circulation well cleanup tool of patent CN207761600U(, 2018.08.24) it discloses a kind of underground and follows
Washing-round well tool, by switch device assembly come into operation, it can be achieved that circulation well cleanup and normal drilling operability free switching.It follows
Ring housing and mandrel are followed using switching device assembly as its state switch when spindle Lock timing by the way of being slidably matched
Achievable normal drilling operability is closed in ring channel, and after putting into derailing switch ontology and locking ball, circulation canal unlatching can be carried out certainly
Dynamic grouting, to realize automatic well-flushing operation, it is only necessary to can be realized by the way of throw-over switch device assembly normal drilling operability and
The switching of well-flushing operation is conducive to bore using making a trip the consumed production time when effectively overcoming existing clean-out service
The raising of well efficiency.
Two above patent has been realized in different forms Infinite Cyclic controlled valve to realize diverter tool state
Purpose, still, as pitching control Infinite Cyclic valve, have the shortcomings that as all kinds of ball-throwing type tools obvious.Firstly,
It needs accurate pitching technology, and miscarrying club increases operating risk；Secondly, ball-throwing type on-off effect speed is slow, and by pitching
It influences drill string assembly and is unable to flexible choice, deviational survey process can only use MWD, can not carry out mechanical deviational survey；Third, due to needing
The derailing switch of special design pitching control, improves the complexity of tool interior structure, to reduce the reliable of tool itself
Property, also improve its maintenance difficulties.
