Description
Technical field
The invention belongs to petroleum natural gas exploration technical fields, and in particular to a kind of cutting bed cleaning tool and use
Method.
Background technique
Cutting bed is that the continuous fractured rock of drill bit is formed in horizontal well drilling, high angle hole, extended reach well, complex structural well
Cutting grain, cutting grain is deposited on horizontal well, high angle hole, extended reach well, complex structural well etc. under the effect of gravity
The lower borehole wall and formed.In daily drilling process, if cannot well Cutting Disposal either control its formation if can
Many drilling problems are caused, such as: 1, increasing annular space mud solid concentration, reduce annular clearance, form elliptical hole, cause to suppress pump
And drilling speed is reduced, increase the swabbing pressure to make a trip；2, keyway and step are easily formed, down-hole accident is caused；3, it is hanged in drilling well
Weight and bit pressure distortion；4, centralizer, the increase of drill collar torque or centralizer mud drum are caused, bit bouncing is caused；5, landwaste sinking causes sand
Card or viscous card；6, cause rotation to increase with frictional resistance is promoted, drill string and casing wear is caused to aggravate；7, bit pressure difficulty is applied to drill string
And ground driving equipment torque is insufficient, influences the effect of drilling；8, make casing tripping in, well cementing operation difficult, cement sealing well matter
The problems such as quantitative change is poor, and all kinds of testing tools and test equipment work are obstructed.
In order to solve the problems, such as that cutting bed is brought, following measures are mainly taken at present: 1, improving and returns fast method, return speed on annular space
It spends higher, is more conducive to remove landwaste, but it is too high to return speed, easily causes top broken ground to collapse chip off-falling, while to drilling equipment
Higher requirements are also raised with drilling tool；2, improve mud property method, generally use MMH mud system, by reducing mud
Liquidity index improves ratio of dynamic shear force/yield value to plastic viscosity, improves mud and takes lithology energy, enhances suspension carrying capacity, but slurry performance adjustion is limited in scope
It needs additionally to add drilling fluid additive, so that drilling cost increases, and higher drilling fluid ratio of dynamic shear force/yield value to plastic viscosity is easy pressure leakage stratum,
Cause leakage；3, the short trip of well section is determined using timing, the measures such as stages cycle and reaming are that is, less serious to cutting bed
Well section can be used short trip, but expend the more time during drilling, influence drilling efficiency, increase indirectly
Add drilling cost.Although above-mentioned several method can achieve the effect that Cutting Disposal highly advantageous to landwaste is removed, can band
To increase and take a long time the problems such as influencing drilling efficiency to drilling equipment and drilling tool requirement raising, drilling cost.Equally reach
Less than quick, stable, efficient Cutting Disposal, to achieve the purpose that high-quality drilling well.
Currently, having developed cutting bed cleanout tool used in drilling process both at home and abroad, there are the following problems: (1) mostly
The landwaste that mineshaft annulus bottom deposit is removed using the cutting bed cleanout tool of Purely mechanical has small part using hydraulic jet
Mode Cutting Disposal, but overall effect is not all good enough；(2) it is different not to be directed to each well section for existing cutting bed cleanout tool
Landwaste deposition, be pointedly purged respectively by same tool using different reset modes；(3) rarely
Waterpower removing is carried out just for cutting bed, without influencing pit shaft upper wall surface, and is to control removing machine by being passed through uninterrupted
The cutting bed cleanout tool that structure opens and closes；(4) cannot the fashionable use under well cementing casing pipe, in long horizontal sections horizontal well set
Pipe tripping in process can still be influenced by cutting bed, and casing is caused to can not be successfully tripping in, influence the progress of well cementing operation.
Summary of the invention
