Description
Technical field
The present invention relates to a kind of play the perfusion of lower tubular column drilling fluid and circulating device and method, belong to oil and gas industry and bore
Well plays lower tubular column technical field of operation.
Background technology
In industrial gas oil, drilling well is the process got through from ground to oil and gas reservoir passage, surveys in petroleum resources
Play a very important role during visiting and developing.In drilling process, well head power-equipment relies on drill string to pass power
Defeated on drill bit, drill bit also gradually wearing out, causes drilling speed to decline while the continuous broken rock in shaft bottom is crept into, certain when may wear to
It is accomplished by more bit change when degree.At this moment it is accomplished by for whole drill strings of down-hole playing out trip-out, again will be complete after more bit change
Bore under portion's drill string G.I.H, here it is the round trip in drilling well.In the well being drilled to according to the rules under depth
Entering the sleeve pipe of certain specification, in order to stablize well, packing bad ground, preparing for creeping into further or exploiting, here it is boring
Casing job in well.Sum up, these in drilling process repeatedly tubing string is included the lower going-into-well such as drilling rod, sleeve pipe bottom
Or to be promoted to the process of well head be exactly lower tubular column operation.Drilling fluid plays very important effect in drilling process, for example
Remove shaft bottom landwaste, equilibrium strata pressure, cooling and lubrication drill bit and drill string, acquisition drilled strata data and transmission drilling well are moved
Power etc..It should according to different situations, be irrigated or circulating fluid operation during playing lower tubular column, it is to avoid due to rising
The bottom pressure that lower tubular column causes is exciting, reduces and avoid the generation of the accidents such as card and blowout that is hampered, meets.
China's oil drilling well is driven in addition to drilling well except minority emphasis well using top, and conventional well mainly adopts rotary drilling, typically needs
To realize perfusion and the circulation of drilling fluid by connecing kelly bar, this is the repeatable operation process of upper button and shackle, wastes time and energy.
If be hampered during making a trip, due to now connecing, kelly bar is difficult, is difficult to realize the circulation of drilling fluid in time, is easily caused
Lock of tool drilling or the generation of gas blowout accident.Develop towards complicated, excessive risk direction with drilling well, how to reduce rotary drilling and remove
The risk of tubing string is extremely urgent.From drilling well production safety and raising standpoint of efficiency, normal for ensureing that drilling well produces
Carry out, in the urgent need to a set of device that can realize drilling well perfusion and circulation during playing lower tubular column.
Content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of lower tubular column drilling fluid that rises to irrigate and circulating device and side
Method.
A kind of brand-new lower tubular column drilling fluid that rises being applied to conventional rotary disk driller irrigates and circulating device, can quickly set up
Circulation of drilling fluid passage, with being reliably connected of tubing string during realizing making a trip, eliminates due to required for circulation of drilling fluid
Kelly bar of frequently unloading operates, and improves rig safety, reduces the generation being hampered or meeting card accident during making a trip；Separately
Outward, the use of this device can avoid, due to quickly playing the wellhead slurry overflow that lower tubular column causes, having improved lower tubular column efficiency.
The technical solution used in the present invention is：

Control system is processed original paper, second pressure table, pressure bypass valve, the 4th pressure regulator valve, the 5th pressure gauge, the 6th is changed by source of the gas
To valve, the 7th reversal valve, the 8th reversal valve, the 9th pressure gauge, the tenth pressure regulator valve composition；
Tenth pressure regulator valve, the 9th pressure gauge and the 8th reversal valve are separately installed with the control piper of motor, by controlling the
The rotating of motor realized by eight reversal valves；
First cylinder is single-acting cylinder, connects the source gas line of cylinder barrel upper end, leads to air on the downside of cylinder barrel；When pressure bypass valve and
6th reversal valve is opened, and bleed pressure is connected in cylinder upper end, and respective action is to promote slide to move upwards；When pressure bypass valve closes
Close, when the 6th reversal valve is opened, adjusting the 4th pressure regulator valve makes the lifting force of the first cylinder be slightly less than the gravity of device body, corresponding
Action slowly declines for slide；
Second cylinder is double-acting cylinder, and the stroke of this cylinder determines the rotational angle of linkage, and cylinder withdraws corresponding
The retracted state of device；Cylinder releases the connection sealing state having corresponded to device；
When elevator is held in above tubing string, rotated forward by control system starter motor, jointing and pipe are driven by reduction box
The quick spinner of post；Connect and be sealingly mounted on jointing；Connect sealing to come in contact and certain pressure occurs with tubing string end face
Contracting amount；When having completed drilling well perfusion and circulation in lower tubular column operation, control motor to rotate backward by control system, connect
Joint and tubing string fast shackle；Operated by control system and drive the first cylinder and the second cylinder, promote jointing to move upwards
Move and be rocked to outside elevator.
2. a kind of play the perfusion of lower tubular column drilling fluid and round-robin method it is characterised in that：
Step 1, the perfusion of lower tubular column drilling fluid will be played and the body of circulating device is fixed on the suspension ring of rig by securing member, even
Connect drilling fluid pipeline and the control gas circuit pipeline of motor, cylinder；
Step 2, rise in lower tubular column operation in drilling well, when needing perfusion and circulating fluid, operated respectively by control system
Two driving cylinders, promote jointing to swing to pithead position and drop to above the tubing string that elevator clamps；
Step 3, operate by control system motor to rotate forward, jointing and the quick spinner of tubing string driven by reduction box,
Now connect sealing and come in contact and occur certain decrement with tubing string end face, produce sealing effectiveness, now open rig
Grouting valve, is irrigated and circulating fluid as needed；
Step 4, at the end of perfusion and circulating fluid, close rig grouting valve, by control system operate motor anti-
To rotation, jointing and tubing string fast shackle；
Step 5, by control system operate driving cylinder, promote jointing move upwards and be rocked to outside elevator, reserve pipe
Post working space, is not interfered with a normally lower tubular column operation, is now normally played lower tubular column operation；
Repeat step 2～step 5, until complete all to play the perfusion of drilling fluid and circulation in lower tubular column operation.
