Description
Technical field
The present invention relates to and a kind of play the perfusion of lower tubular column drilling fluid and circulating device and method, belong to oil and gas industry drilling well and play lower tubular column technical field of operation.
Background technology
In industrial gas oil, the process from ground to oil and gas reservoir passage is got through in drilling well, plays a very important role in the process of Exploration of Oil And Gas and exploitation.In drilling process, well head power-equipment relies on drill string to transmit power on drill bit, and drill bit constantly breaks while rock creeps in shaft bottom and also wearing and tearing gradually, causes drilling speed to decline, in time may wear to a certain degree, just needs more bit change.At this moment just need whole drill strings of down-hole to trip out trip-out, more bore under whole drill string G.I.H again after bit change, the round trip in drilling well that Here it is.In the well be drilled to, enter the sleeve pipe of certain specification according to the rules under the degree of depth, in order to stable well, packing bad ground, prepare for creeping into further or exploiting, the casing job in drilling well that Here it is.Sum up, these processes being comprised by tubing string at the bottom of the lower going-into-well such as drilling rod, sleeve pipe or be promoted to well head repeatedly in drilling process play lower tubular column operation exactly.Drilling fluid plays very important effect in drilling process, such as, remove shaft bottom landwaste, equilibrium strata pressure, Cooling and Lubricator drill bit and drill string, acquisition drilled strata data and transmission drilling dynamics etc.In the process playing lower tubular column, according to different situations, should carry out pouring into or circulating fluid operation, avoid owing to playing the bottom pressure that causes of lower tubular column exciting, reduce and avoid being hampered, meet and block and the generation of the accident such as blowout.
China's oil drilling well is except driving except drilling well in minority emphasis well employing top, and conventional well mainly adopts rotary drilling, and generally need the perfusion and the circulation that realize drilling fluid by connecing kelly bar, this is the operating process repeatedly of upper button and shackle, wastes time and energy.If be hampered in the process of making a trip, owing to now connecing kelly bar difficulty, be difficult to the circulation realizing drilling fluid in time, easily cause the generation of lock of tool drilling or gas blowout accident.Along with drilling well is towards complicated, excessive risk future development, how to reduce the risk that rotary drilling plays lower tubular column, extremely urgent.From drilling well production safety and raise the efficiency angle, be normally carrying out of ensureing that drilling well produces, can the device that realize drilling fluid perfusion and circulation be being played in lower tubular column process in the urgent need to a set of.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides and a kind of play the perfusion of lower tubular column drilling fluid and circulating device and method.
A kind of lower tubular column drilling fluid that rises being applicable to conventional rotary disk driller completely newly pours into and circulating device, circulation of drilling fluid passage can be set up fast, realize being connected with the reliable of tubing string in the process that makes a trip, eliminate the kelly bar operation of unloading frequently required for circulation of drilling fluid, improve rig safety, reduce in the process that makes a trip the generation being hampered or meeting card accident; In addition, the use of this device can avoid the wellhead slurry overflow caused owing to playing lower tubular column fast, has improved lower tubular column efficiency.

Step 1, will the perfusion of lower tubular column drilling fluid be played and the body of circulating device is fixed on the suspension ring of rig by securing members such as U-bolts, connect the control gas circuit pipeline of drilling fluid pipeline and motor, cylinder;
Step 2, rise in lower tubular column operation in drilling well, when needs perfusion and circulating fluid, operate two driving cylinders respectively by control system, promote jointing and swing to pithead position and drop to above tubing string that elevator clamps;
Step 3, to be rotated forward by control system operation motor, drive jointing and the quick spinner of tubing string by reduction box, now connect sealing and come in contact with tubing string end face and certain decrement occurs, generation sealing effectiveness.Now can open the grouting valve of rig, carry out as required pouring into and circulating fluid;
Step 4, at the end of perfusion or circulating fluid, close the grouting valve of rig, rotated backward by control system operation motor, jointing and tubing string fast shackle;
Step 5, operate driving cylinder by control system, promote jointing and move upward and be rocked to outside elevator, reserve tubing string working space, do not play a lower tubular column operation interfere with normal, now can play lower tubular column operation normally;
Repeat step 2 ~ step 5, until complete the perfusion and circulation that all play drilling fluid in lower tubular column operation.
