Part of the body (10), and it has visor (11) just to start the body (10) overcoat, terminal surface position installation shear pin (12) under visor (11) outside main part (9) middle part, main part (9) lower extreme cup joints lower clutch (13). It is empty to seal oil sleeve annulus, and single tripping operation petroleum string accomplishes the construction, and is easy and simple to handle, sits and seals rapidly, and sealing performance is good, and the deblocking is reliable, easy to maintain, and can be restoreed 3 times, reduce card well probability, have the function of compensator in the pit simultaneously concurrently.
Description
Technical field
This utility model relates to the structure improvement technology of oil/gas drilling test oil producing operation device, especially steam injection packer.
Background technology
Packer means have elastic sealing elements, and annular space between packing various sizes tubing string and well and between tubing string whereby, and completely cuts off payzone, to control to produce (note) liquid, protects the downhole tool of sleeve pipe.
Thermal packer is applicable to the ideal tools of thick oil heat production steam injection.In petroleum production engineering, packer is used for being layered, and packer is designed with oil recovery passage, and when setting, piston bush is up, and oil recovery passage is opened；After setting, overlaminate power acts on dummy piston, is pushed up packing element, makes deblocking pin from shearing force；During deblocking, the frictional force by packing element Yu sleeve pipe cuts off deblocking pin, and piston bush is descending, closes oil recovery passage.
Utility model content
The purpose of this utility model is to provide steam injection packer.
The purpose of this utility model will be realized by techniques below measure: includes heat-insulated pipe hooping, compensate pipe, main body, startup body, protection cap, shear pin and lower contact；Compensating pipe upper end and connect heat-insulated pipe hooping, compensate pipe lower end and connect main body, main Ligation in vitro starts body, and starts the external protection cap that is cased with, in the middle part of main body outside position, protection cap lower surface shear pin, the socket lower contact of main body lower end are installed.
Especially, compensate pipe upper end and connect heat-insulated pipe hooping by upper sealing ring.
Especially, installing in main body and start body position overcoat sealed rubber pipe, this sealed rubber pipe lower end is socketed on the upside of protection cap, and sealed rubber pipe upper end connects lid, connects lid liner sealing gland, and sealing gland is socketed in compensation pipe and main body junction outer rim.Wherein, compensate pipe and be connected end sealing ring along installation with main body, be embedded in lower sealing ring in inner edge, sealed rubber pipe upper end.
Advantage of the present utility model and effect: oil jacket annular space can be closed, single plays lower tubular column and completes construction, easy and simple to handle, sets rapidly, good seal performance, deblocking is reliable, it is easy to safeguard, and can be repaired 3 times, reduce card well probability, have the function of down-well compensator simultaneously concurrently.
Accompanying drawing explanation
Fig. 1 is this utility model embodiment 1 structural representation.
Reference includes: heat-insulated pipe hooping 1, upper sealing ring 2, compensate pipe 3, sealing gland 4, connect lid 5, middle sealing ring 6, lower sealing ring 7, sealed rubber pipe 8, main body 9, start body 10, protection cap 11, shear pin 12, lower contact 13.
Detailed description of the invention
This utility model principle is, in steam injection process, when temperature reaches 200 DEG C or higher, packer expands generation action by starting body deformability and sealing drum, it is achieved set.
This utility model includes: heat-insulated pipe hooping 1, compensation pipe 3, main body 9, startup body 10, protection cap 11, shear pin 12 and lower contact 13.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment 1: as shown in Figure 1, compensates pipe 3 upper end and connects heat-insulated pipe hooping 1, compensates pipe 3 lower end and connects main body 9; main body 9 outer connection starts body 10; and start the body 10 protected lid of overcoat 11, in the middle part of main body 9 outside position, protection cap 11 lower surface install shear pin 12, main body 9 lower end socket lower contact 13.
In aforementioned, compensate pipe 3 upper end and connect heat-insulated pipe hooping 1 by upper sealing ring 2.
In aforementioned, installing in main body 9 and start body 10 position overcoat sealed rubber pipe 8, this sealed rubber pipe 8 lower end is socketed on the upside of protection cap 11, and sealed rubber pipe 8 upper end connects lid 5, connects lid 5 liner sealing glands 4, and sealing gland 4 is socketed in compensation pipe 3 and main body 9 junction outer rim.Wherein, compensate pipe 3 and be connected end sealing ring 6 along installation with main body 9, be embedded in lower sealing ring 7 in inner edge, sealed rubber pipe 8 upper end.
In the present embodiment, compensate pipe 3 external diameter 7 cun, internal diameter 6 cun, connecting screw thread is Europe superscript 27/8TBG tubing round thread, top is box, under be not pin thread, minimum diameter 62mm, maximum inner diameter 152mm, packer location maximum operating pressure differential 2Ma, maximum operating temperature 360 DEG C, maximum functional attempts 2100mm, without operating angle 0-90 DEG C under centralizer, 160 °/30m of greatest gradient, minimum temperature 200 DEG C needed for packer setting, act on peak torque 2500Nm on packer, go into the well maximum speed 30m/min, overall length 6096mm, weight 95kg, working media is water, steam, oil, natural gas or its mixture, it is not suitable for >=the H of 50ppm2S, HCL, HF and other acid medium.
This utility model, can close oil jacket annular space, have the function of down-well compensator simultaneously concurrently, and in steam injection process, when temperature reaches 200 DEG C or higher, packer expands generation action by starting body deformability and sealing drum, it is achieved set；After packer packing, pin is cut off, and packer body slides on compensator, steam injection string thus there is extending space, starting body and sealing drum after gas injection shrinks, removing seal for packer.
