Background technology
At present, in oil field development, along with increasing that deep-well, Holes of Complicated Wells drilling are developed, especially completion
The continuous innovation of technique, various functions and use to completion tool are had higher requirement.Hydraulic pressure is sat
Envelope instrument is the direct drive mechanism of packer setting in gravel filling sand prevention operation, traditional setting tool
Mainly include the various structures such as machinery setting tool, cable setting tool and hydraulic setting tool, but through adjusting
Research and development are existing, and aforementioned setting tool exists following technical bottleneck.Machinery setting tool unfailing performance is low, especially
It is for some high angle holes, it is impossible to make packer set completely extremely；Cable setting tool enters electricity under needing
Cable, construction extremely inconvenience, and operating cost is higher；When using hydraulic setting tool construction, due to hole condition
Complexity, easily occurs the phenomenon that is hampered under packer during entering, without safeguard, can produce
The risk of premature setting.
Summary of the invention
The present invention solves that technical problem present in known technology provides a kind of for gravel pack completion
Sand control treatment, it is possible to decrease operating cost and set operation reliable and effective hydraulic setting tool.
The present invention solves that technical problem is adopted the technical scheme that present in known technology:
Hydraulic setting tool, the mandrel being connected with top connection including top connection, also include being arranged on mandrel
Outside piston propulsion mechanism and shifter；Described piston propulsion mechanism includes: sealing shroud is contained in mandrel
Outside piston and the conversion sleeve of piston one end external connection and the sliding sleeve being connected with top connection, described
Being fixed by shear pin between mandrel and piston, described sliding sleeve is solid with top connection circumference by fixing pin
Fixed；Described shifter includes: piston and be sleeved on the regulation set outside conversion sleeve；Make in described mandrel
There are at least 4 pressure transmission holes；It is characterized in that: described conversion sleeve is provided with 4 bullets of even circumferential distribution
Property pawl.
The present invention can also adopt the following technical scheme that
Described sliding sleeve outer surface uses and can ensure that the smooth of the unblocked power of running string waits gauge structure.
Described conversion sleeve uses threaded adjusting assembling with regulation set.
The shear pin of described hydraulic setting tool is designed as bearing the circulating pressure of 1100-1300psi,
With ensure under enter process circulating pressure will not cut off shearing copper pin, prevent premature setting.
The present invention has the advantage that with good effect: owing to the present invention uses technique scheme, the most logical
Cross and the copper pin of shearing is set between mandrel and piston, and copper pin shear force is stable, so can increase
Add and prevented ensureing together of packer premature setting, simultaneously the conversion sleeve of hydraulic setting tool and regulation set
Coordinate with top packer and can effectively prevent packer premature setting, make to set operation the most effective.This
Outward, this hydraulic setting tool can coordinate top packer and the sump packer etc. of outer layer sand preventing tool multiple
Packer realizes setting operation；This instrument also has that cost is low, assembly program simple, execute-in-place process
Convenient and safe and reliable advantage.

Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example,
And it is as follows to coordinate accompanying drawing to describe in detail:
Refer to Fig. 1, hydraulic setting tool, the mandrel 9 being connected with top connection including top connection 1, go back
Including the piston propulsion mechanism being arranged on outside mandrel and shifter, described top connection is fixed by second
Pin 5 is fixing with mandrel to be connected.
Described piston propulsion mechanism includes: sealing shroud is contained in outside the piston 8 outside mandrel and piston one end
Conversion sleeve 11 that portion connects and the sliding sleeve 2 threadeded with top connection are logical between described mandrel and piston
Crossing shear pin 6 to fix, described sliding sleeve is circumferentially fixed with top connection by the first fixing pin 3, in case
Relatively rotating between anti-skid sheath and top connection circumference.It is equipped with between described piston and sliding sleeve, mandrel
Two sealing rings 7, are provided with the first sealing ring 4 between described top connection and sliding sleeve.
Described shifter includes: piston 8 and the regulation set 12 being sleeved on outside conversion sleeve, described regulation
Set uses Screw assembly with conversion sleeve；The relative position of conversion sleeve and regulation set is regulated by regulation screw thread,
And fixed by fixing pin, it is achieved conversion sleeve and the location of top packer junction.By pin 10
Regulate the relative position of fixed conversion set and top packer
In the present embodiment, described mandrel is shaped with at least 4 pressure transmission hole 9-1.
In the present embodiment, described sliding sleeve outer surface uses smooth grade for gauge structure, in order to ensure that running string is smooth
Logical non-resistance.
In the present embodiment, described conversion sleeve 11 is provided with 4 elastic claw 11-1 of even circumferential distribution.
In the present embodiment, the shear pin 6 of described hydraulic setting tool uses shears copper pin, described
The shear pin 6 of hydraulic setting tool is designed as bearing the circulating pressure of 1100-1300psi, it is ensured that under
Enter process circulating pressure and will not cut off shear pin, prevent premature setting.
Use the operational approach of hydraulic setting tool, comprise the steps:
Assemble hydraulic setting tool and top packer, it is necessary first to serviced with other by hydraulic base sealed instrument
Instrument is successfully inserted in top packer, and the conversion sleeve 11 of the most hydraulic base sealed instrument is axially inserted into top
In groove within portion's packer, it is adjusted axially the regulation set 12 outside conversion sleeve tighter to its end face
The top of patch top packer, and hook top packer by the locking shoulder of conversion sleeve, finally go up
Fasten screw.Only overlap the most descending when the piston 8 of hydraulic setting tool with conversion sleeve, regulation
Time, the setting mechanism outside top packer just can be made descending, therefore achieve top packer under entered
Will not be the most descending in journey, it is to avoid the risk of its premature setting.
Set operation: suppress to hydraulic setting tool mandrel interior, push down on piston by pressure, first
First cutting off shear pin smoothly, then piston continues traveling downwardly, and drives conversion sleeve and the regulation of piston exterior
Overlap the most descending, finally, it is achieved setting smoothly of packer.
By different completion practice demands, this hydraulic setting tool can serve top packer and sand setting packing
Device, suppresses in service aid to 17MPa, can realize setting smoothly of packer and put in place.
