Abstract
The utility model relates to a heavy crude horizontal well testing column jacket suspended airproof device for heavy crude steam perfusion SAGD extraction technique, which comprises a packing gland 1, a hub bed flange 2, a pad ring 3, a taper sleeve 4, a locking apparatus 5, a top wire 6 and packings 7. The bore of the hubbed flange 2 is from up to bottom provided with a packing gland 1, packings 7, a pad ring 3 and a taper sleeve 4, wherein a locking apparatus 5 is arranged. The top wire 6 is connected with the horizontal feed hole on the upper side of the flange 2 through screws. The device has simple, compact and practical conformation, and can achieve suspended airproofing of the testing column jacket within small space. Also, the utility model achieves convenient operation process due to the multi-clove conformation of a plurality of components such as the packing land, the packings, the locking apparatus, and pad rings and the like.
Description
Technical field:
The utility model relates to a kind of special-purpose member that is used for thick oil filling steam SAGD production practice horizontal well wellhead assembly.
Background technology:
At present, the down-hole string suspension sealing device of field by using has multiple structure, but but there is not compact conformation can satisfy the test string suspension sealing device that thick oil filling SAGD (SAGD) production practice requires simultaneously, thereby be difficult to SAGD oil production technology heavy oil wells down-hole oil reservoir production status is carried out normally and accurately test job, thereby to improving, improve heavy oil wells output and exploitation effect formation adverse effect.
The utility model content:
The purpose of this utility model is to provide a kind of thick oil horizontal well test string suspension sealing device that can satisfy and solve test string suspension seal request in the thick oil horizontal well SAGD oil production technology.
The utility model is to realize like this.This kind test string suspension sealing device is made up of welding neck flange, gland, filler, gasket ring, tapered sleeve, locking device and jackscrew, be provided with gland, filler, gasket ring and tapered sleeve in the welding neck flange chamber from top to bottom successively, be provided with locking device in the tapered sleeve, be provided with jackscrew in one side through hole of flange top.This suspension sealing device adopts the self-locking type structure, place the locking device in the tapered sleeve to adopt the multi-clove type structure, because cone structure is also adopted in its lower end, more down internal diameter is more little, thereby realization locking function, with test string locking, the locking device inner headed face is provided with screw thread in order to the fixing test tubing string simultaneously.In addition, the gland, filler, the gasket ring that are provided with in this device welding neck flange upper chambers all adopt the multi-clove type structure, can compress gland by the jackscrew that rotates a side, realize sealing function thereby compress airtight and watertight padding.
The utility model is simple in structure, compact, practical, can in very little space, realize the suspension sealing of test string, and, because a plurality of component such as gland, filler, locking device, gasket ring all adopt the multi-clove type structure, make the whole operation process very convenient.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of gland 1, welding neck flange 2, gasket ring 3, tapered sleeve 4, locking device 5, jackscrew 6 and filler 7, its structure, assembled relation are as follows: be provided with gland 1, filler 7, gasket ring 3 and tapered sleeve 4 in welding neck flange 2 chambeies from top to bottom successively, be provided with locking device 5 in the tapered sleeve 4, with screwed connection jackscrew 6 arranged in the one side cross through hole of flange 2 tops.Wherein, welding neck flange 2 tops are the disc type flange body, and the middle part is a cylinder, and the bottom is a cone, and the middle part inner headed face is provided with sits the round platform of putting locking device 5, and upper flange body one side is provided with horizontal top wire hole.Tapered sleeve 4 is the straight sleeve of periphery, and the internal diameter up big and down small conical surface that is in inner headed face bottom is in order to match with locking device 5.Locking device 5 adopts the multi-clove type structure, and the lower end periphery is the conical surface that matches with tapered sleeve 4 inner headed faces, and inner headed face has suspension test string screw thread.Gland 1, filler 7, gasket ring 3 all adopt the multi-clove type structure.
