Abstract
The utility model relates to a cementing tool belongs to oil brill, well completion field. A float pipe tool that traps from crushing -type mainly comprises ectosome, elasticity spacer ring, blind plate and well cementation ring, and the ectosome both ends are the link, and the ectosome is equipped with the elasticity spacer ring in the middle part, is equipped with the blind plate in the elasticity spacer ring inside, and the well cementation encircles in the ectosome and locates elasticity steel ring upper portion. The utility model discloses a float pipe tool that traps from crushing -type makes the process operation of well cementation simple, reliable. The activity duration and the operation of well cementation cost is reduced.
Description
Technical field
This utility model relates to a kind of cementing tool, belongs to petroleum drilling, completion field.
Background technology
In recent years, the development mode such as horizontal well, extended reach well achieves preferable effect in each oil field, traps
Pipe operation is vital link in horizontal well, extended reach well drilling process, and the quality of setting of casing quality is straight
Connect and have influence on crude output and oil well life-span.At present due to well track on many horizontal well, extended reach wells
Many reasons such as bad, cause pit shaft frictional resistance too big, make to enter under sleeve pipe difficulty, cause for subsequent job all
The most inconvenient.
Summary of the invention
In order to solve problems of the prior art, this utility model provide a kind of from breaking floating under
Sleeve tool, enters to be hampered in the horizontal well with difficulty and extended reach well under main application well cementing process middle sleeve,
Overcome existing floating coupling to get through risk height, and need to bore the problem except internal metal parts, by using
The pressure that casing string is pushed in well is added, it is achieved under sleeve pipe is smooth from breaking floating casing appliances
Enter.
The technical solution of the utility model is as follows:
A kind of from breaking floating casing appliances, mainly by ectosome, elastic spacer ring, blind plate and well cementation ring group
Become, ectosome two ends for connecting end, in the middle part of ectosome in be provided with elastic spacer ring, be provided with blind plate in elastic spacer ring inside,
Well cementation ring is the most internal and is located at flexible steel ring top.
Wherein blind plate can be made up of broken extraordinary military project material.
It is mainly used in horizontal well and extended reach well from breaking floating casing appliances, during setting of casing, will
It is connected on casing string from breaking floating casing appliances, in sleeve pipe, constitutes temporary barrier, from breaking
Air it is full of in casing string below floating casing appliances, and more than breaking floating casing appliances
Drilling fluid it is full of in casing string.Which adds from breaking floating casing appliances following part tubular post
Buoyancy, it is achieved bottom bunch tube is in floating state during lower pipe box, reduces resistance during setting of casing
Power, and owing to being filled with drilling fluid in the casing string of floating coupling above section, thus add a sleeve pipe
Post pushes the pressure in well, it is achieved enter under sleeve pipe is smooth.
Of the present utility model make the process operation of well cementation simple, reliable from breaking floating casing appliances.Fall
The activity duration of low well cementation and operating cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, it is of the present utility model from breaking floating casing appliances, mainly by ectosome 1, elasticity
Spacer ring 2, blind plate 4 and well cementation ring 3 form, ectosome two ends for connecting end, in the middle part of ectosome in be provided with elastic spacer ring
2, it is provided with blind plate 4 in elastic spacer ring 2 inside, well cementation ring 3 is the most internal and is located at flexible steel ring top.
Construction technology step:
A) go through from breaking floating casing appliances and adnexa thereof, check from breaking floating setting of casing
The outward appearance of instrument is not collided with；The rubber parts of plug stands intact；Supporting special float collar and the connection of float shoe
Whether screw thread mates with sleeve pipe.
B) enter down float shoe, float collar, connect sleeve pipe, in sleeve pipe, be not required to grouting, note controlling lowering velocity.
C) enter repeatedly from breaking floating casing appliances, sleeve grouting, 20 sleeve groutings at design attitude
Once, note controlling the lowering velocity of sleeve pipe, particularly when close to design attitude under sleeve pipe to be controlled
Put speed, prevent from opening in advance from breaking floating casing appliances.
D) after sleeve pipe puts in place, filling mud in sleeve pipe, well head builds the pressure, and opens from the breaking floating plumber that traps
Tool, sets up circulation.
E) after circulation is normal, carry out cementing job, after having broken cement, put into top cement plug, pump into tamponade liquid,
Then replace with mud, until bruising.Complete well cementing operation.
Claims (2)
1. one kind from breaking floating casing appliances, it is characterised in that mainly by ectosome, elastic spacer ring, blind plate
With well cementation ring composition, ectosome two ends for connecting end, in the middle part of ectosome in be provided with elastic spacer ring, inside elastic spacer ring
Inside being provided with blind plate, well cementation ring is the most internal and is located at flexible steel ring top.
2. as claimed in claim 1 from breaking floating casing appliances, it is characterised in that described blind plate is easy
The blind plate that broken extraordinary military project material is made.
