Abstract
A heat-sensitive packer of a steam injection well comprises a main body, heat-sensitive pieces, baffle plates, spacing rings, frameworks, sealing pieces, fixing rings and fixing bolts, wherein a plurality sections of external threads are arranged below the upper end thread and above the lower end thread of the main body and connected with the spacing rings and the fixing rings, so as to form a plurality of concave grooves on the main body, and the heat-sensitive pieces, the baffle plates, the frameworks and the sealing pieces are mounted in the grooves from inside to outside. The utility model has the benefits that as the heat-sensitive pieces, the baffle plates, the frameworks and the sealing pieces are sleeved in from the lower part of the main body for mounting, the sealing pieces are not required to be deformed, and are prevented from being damaged during the assembly, the sizes of the sealing pieces are not limited by the installation in the sleeved manner, and can be enlarged, and the strength and the air-tightness is enhanced; and under the action of the frameworks, even the steam injection pipe columns are contracted by heating during the process of injecting steam, as the concave grooves formed on the main body are rather deep, the sealing pieces are prevented from slipping off from the grooves, and the heat-sensitive packer has excellent sealing effect and long service life, and can be repeatedly used.
Description
Technical field
The utility model belongs to oil thermal recovery and annotates the equipment that the vapour well is used, and is to annotate vapour well temperature-sensitive packer.
Background technology
When the steam injection of oil thermal recovery well, require the steam pressure height of injection, heat waste was few when temperature height, steam arrived the stratum from well head.In order to reach the few purpose of heat waste, generally be the notes vapour well temperature-sensitive packer that high temperature high voltage resistant is installed on the steam injection tubing string that injects on the stratum, steam is not flow to cause heat waste in the sleeve pipe.Existing notes vapour well temperature-sensitive packer kind is more, but all comes with some shortcomings, and is 00252598.4 thick oil filling vapour thermal packer as the patent No., when seal is installed, be inserted in the groove of central tube after seal is increased, the seal distortion is big, cause seal to damage easily, sealing effectiveness is bad, and when steam injection, steam injection string is heated and will stretches, steam injection string is heated in the journey that will stretch, seal is deviate from groove easily, causes blow-by, does not have heat insulation effect.
Summary of the invention
The purpose of this utility model is a kind of notes vapour well temperature-sensitive packer of design, makes its seal of annotating vapour well temperature-sensitive packer not need distortion just can install, and does not damage seal when seal is installed, and seal can be from not coming off.
The purpose of this utility model is achieved in that it is made up of main body, thermosensitive part, baffle plate, spacer ring, skeleton, seal, retainer ring, hold-down screw.The upper and lower end of main body has screw thread, the upper end screw thread is connected with insulated tubing, the lower end screw thread is connected with the afterbody oil pipe, under the screw thread of main body upper end, the multistage external screw thread is arranged on the screw thread of lower end, these multistage external screw threads are connected with spacer ring, retainer ring, make it form a plurality of Baltimore grooves on main body, and thermosensitive part, baffle plate, skeleton, seal outwards are installed from the lining in Baltimore groove.Hold-down screw is connected between spacer ring, retainer ring and the main body.
The beneficial effects of the utility model are, install quick, when baffle plate, skeleton, seal, be inserted in from lower body part, do not need the seal distortion, can when assembling, not be damaged, the seal size is not limited by suit, can amplify, and gains in strength and sealing, because the effect of skeleton is arranged, when steam injection, though that steam injection string is heated is flexible, because a plurality of Baltimore groove degree of depth that form on main body are darker, seal can not deviate from groove, good sealing effect, long service life, reusable.
Description of drawings
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with Fig. 1 embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model is made up of main body 1, thermosensitive part 2, baffle plate 3, spacer ring 4, skeleton 5, seal 6, retainer ring 7, hold-down screw 8.The upper and lower end of main body 1 has screw thread, the upper end screw thread is connected with insulated tubing, the lower end screw thread is connected with the afterbody oil pipe, under the screw thread of main body upper end, the multistage external screw thread is arranged on the screw thread of lower end, these multistage external screw threads are connected with spacer ring 4, retainer ring 7, make it form a plurality of Baltimore grooves on main body 1, and thermosensitive part 2, baffle plate 3, skeleton 5, seal 6 outwards are installed from the lining in Baltimore groove.Hold-down screw 8 is connected between spacer ring 4, retainer ring 7 and the main body 1.
