Abstract
The invention discloses an operation method achieved through an automatic grouting and drilling fluid circulating system. The operation method includes a grouting operation process and a drilling fluid circulating operation process in casing running operation. During casing running construction, when drilling fluid needs to be poured after a casing is screwed on, a slime pump is started, and high-pressure drilling fluid enters an automatic grouting device through a high-pressure hose and is poured into the casting to balance annulus pressure inside and outside the casing; and when casing running is blocked or jammed, the automatic grouting device is inserted into the casting, after a drilling fluid pipe is full, the drilling fluid returns upwards to expand a sealing packing cup, the casting is closed, and the automatic grouting device is stopped, so that drilling fluid circulating operation is completed.
Description
Technical field
The present invention relates to well drilling well completion casing field of operation, especially a kind of automatic grouting that passes through bores with circulation
The operational method that well liquid system realizes.
Background technology
Setting of casing is very important link in wellbore construction, and during setting of casing, the back pressure of casing float collar is all
You are closed, and are easily deformed by after annular space head of liquid in sleeve pipe, and so under the influence of meeting, step is bored
Well construction, therefore should try one's best during setting of casing many irrigates drilling fluid in sleeve pipe, with in balancing sleeve,
External pressure.The many employings of situ of drilling well at present are artificially infused to mode, and this mode wastes time and energy.Owing to drilling fluid fills
It is discontinuous for entering, and must stop casing job during drilling fluid charge, it is easy to occur not go or cutting ferrule under sleeve pipe
The accidents such as pipe.Some construction well employs self-filling-type float collar and float shoe, it is desirable to rely on self-filling-type float collar and float shoe
In trend sleeve pipe irrigate drilling fluid, but due in float collar and float shoe spheroid by drilling fluid extrusion damage, go out
The existing malfunctioning situation of provisions for grouting.Above method all cannot ensure that sleeve pipe is lower to shaft bottom smoothly, there is much safety
Hidden danger, easily causes the generation of down-hole accident.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and is realized by automatic grouting and circulating fluid system
Operational method, it is capable of overlapping ipe grout and cycle operation, and ensures to enter with follow-up under sleeve pipe is smoothly
Well cementing operation.
In order to solve above-mentioned technical problem, the one of the present invention is real by automatic grouting and circulating fluid system
Existing operational method, automatic grouting and circulating fluid system used in this operational method include slush pump
And set gradually from top to bottom high pressure vertical tube, rig tourist bus, water under high pressure cage band, suspension ring, automatic grouting
Device, sleeve pipe, upper chuck and lower chuck；
This operational method includes that in casing job, in cementing operations technique and casing job, circulating fluid is made
Industry technique；
In casing job, cementing operations technique comprises the following steps:
1) when needs are in the milk, slush pump is opened；
2) cleaner for high-pressure drilling fluid is carried out in water under high pressure cage band by high pressure vertical tube；
3) in water under high pressure cage band, drilling fluid enters automatic grouting equipment；
4) cleaner for high-pressure drilling fluid opens the relief valve of automatic grouting equipment, then by the endoporus of starting taper, pours into sleeve pipe
In；
5) when stopping grouting, slush pump is closed；
6) relief valve of automatic grouting equipment is under the action of the spring, closes grouting channel, stops cementing operations；
In casing job, circulating fluid operation technique comprises the following steps:
1), at the end of transferring be hampered (chance card) or setting of casing construction when bunch tube, lower chuck gripping sleeve is closed,
Opening upper chuck, transfer rig tourist bus, in the seal assembly of automatic grouting equipment inserts sleeve pipe, rear closing is closed
Chuck；
2) carry rig tourist bus on, open lower chuck；
3) opening slush pump, drilling fluid enters the relief valve of automatic grouting equipment, and open the safety-valve entrance sleeve pipe
In；
4) when in sleeve pipe, mud is filled, mud return in the seal assembly groove entering automatic grouting equipment,
Under mud pressure effect, sealing cup expands so that is formed between automatic grouting equipment and sleeve pipe and closes
Annular space, mud can only return high pressure vertical tube and slush pump by automatic grouting equipment, eventually forms mud circulation；
5) while mud circulation, raise and decentralize rig tourist bus, transfer be hampered (meeting card) when bunch tube and solve
After having determined, stop mud circulation, continue setting of casing construction；
6) if to shaft bottom under sleeve pipe, then it is carried out continuously twice mud cycle operation, after circulation, stops
Circulation, connects cementing tool, prepares follow-up well cementing operation.
The invention has the beneficial effects as follows: it is loaded down with trivial details that the present invention is no longer necessary to manual grouting and connection drilling team water cage band etc.
Process, grouting and circulating fluid are rapid, it is possible to resolve sleeve pipe is hampered and meets the problems such as card, and safety is high, subtracts
Light labor strength, reduces the non-casing job time, reduces underground construction difficulty.
Accompanying drawing explanation
Fig. 1 is automatic grouting and the structured flowchart of circulating fluid system in the present invention.
Detailed description of the invention
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings:
See Fig. 1, a kind of operational method realized by automatic grouting and circulating fluid system of the present invention,
Automatic grouting and circulating fluid system used in this operational method include slush pump and depend on from top to bottom
The high pressure vertical tube of secondary setting, rig tourist bus, water under high pressure cage band, suspension ring, automatic grouting equipment, sleeve pipe, on
Chuck and lower chuck；
This operational method includes that in casing job, in cementing operations technique and casing job, circulating fluid is made
Industry technique；
In casing job, cementing operations technique comprises the following steps:
1) when needs are in the milk, slush pump is opened；
2) cleaner for high-pressure drilling fluid is carried out in water under high pressure cage band by high pressure vertical tube；
3) in water under high pressure cage band, drilling fluid enters automatic grouting equipment；
4) cleaner for high-pressure drilling fluid opens the relief valve of automatic grouting equipment, then by the endoporus of starting taper, pours into sleeve pipe
In；
5) when stopping grouting, slush pump is closed；
6) relief valve of automatic grouting equipment is under the action of the spring, closes grouting channel, stops cementing operations；
