Description
Technical field
The utility model relates to the improvement of perforating bullet, is a kind of pair of cavity liner perforating bullet specifically, belongs to the perforation equipment that uses in oil exploration and the mining operations.
Background technology
In oil exploration and mining operations, need select perforating bullet for use and utilize perforating gun that the down-hole petroliferous bed is carried out perforating job.Existing perforating bullet has two kinds substantially: the deep penetrating charge of being made up of deep penetration powder column, deep penetration cavity liner, deep penetration body and form the large aperture perforating bullet by large aperture powder column, large aperture cavity liner, large aperture body.The performance of deep penetrating charge and large aperture perforating bullet is completely different, exists the defective that penetration depth and aperture can not be taken into account greatly simultaneously separately respectively.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, provide a kind of simple in structure, processing and easy to use, have two cavity liner perforating bullets of deep penetration and large aperture performance simultaneously.
The purpose of this utility model is achieved in that
This pair of cavity liner perforating bullet, the deep penetrating perforating unit that constitutes by deep penetration powder column, deep penetration cavity liner and deep penetration body and form by the perforation unit, large aperture that large aperture powder column, large aperture cavity liner and large aperture body constitute, be characterized in that the deep penetration body fixedlys connected with the large aperture body, the propagation of explosion unit that is made of intermediate, booster gains and propagation of explosion cavity liner is housed on the deep penetration body.
The two ends of described propagation of explosion unit booster gains are connected with the large aperture powder column with the deep penetration powder column respectively, and the two ends of propagation of explosion unit propagation of explosion cavity liner are connected with the large aperture cavity liner with the deep penetration cavity liner respectively.
Described deep penetration cavity liner and propagation of explosion cavity liner are conical liner, and the large aperture cavity liner is the arc cavity liner.
The cross sectional shape of the intermediate of described propagation of explosion unit is a right-angled triangle.
Be provided with propagation of explosion hole and the detonating fuse groove that is connected with the deep penetration powder column on the top of deep penetration body.
Fixedly connected with screw thread between described deep penetration body and the large aperture body.
The utility model is simple in structure, can select the raw material of existing perforating bullet for use, and adopts conventional processes to make, and implements easily.
Distinctive feature of the present utility model is, between deep penetrating perforating unit and perforation unit, large aperture, be provided with the propagation of explosion unit, reach the combination between deep penetrating perforating unit and the perforation unit, large aperture, realized that a perforating bullet has the dark and big dual performance in perforation diameter of perforating depth simultaneously, and, because the setting of the intermediate in the propagation of explosion unit, prevent the interference between deep penetrating perforating unit and the perforation unit, large aperture, realized stable propagation of explosion and noiseless acting respectively between deep penetrating perforating unit and the perforation unit, large aperture.
During use, this pair of cavity liner perforating bullet is contained in the existing various perforating gun, the deep penetrating perforating unit at first detonates, after the deep penetrating perforating unit detonates, cause perforation unit, large aperture by booster gains and detonate in good time, in a perforating job, reach the dark and big effect in perforation diameter of perforating depth simultaneously.
The utlity model has simple in structure, handling ease, easy to use, perforating bullet and have advantages such as the dual performance of deep penetration and large aperture, work safety are stable simultaneously, can be in a perforating job after the enforcement, reach the dark and big effect in perforation diameter of perforating depth simultaneously, to improve oil recovery efficiency greatly after applying, reach the purpose of incremental oil production.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is that a kind of embodiment of the utility model is contained in the user mode structural representation in the perforating gun.
Among the figure: the 1 pair of cavity liner perforating bullet, 2 deep penetration powder columns, 3 deep penetration cavity liners, 4 deep penetration bodies, 5 large aperture powder columns, 6 large aperture cavity liners, 7 large aperture bodies, 8 intermediates, 9 booster gains, 10 propagation of explosion cavity liners, 11 propagation of explosion holes, 12 detonating fuse grooves; 01 perforating gun, 02 detonating fuse, 03 firing mount.
The specific embodiment
The utility model is further described with the embodiment that provides below in conjunction with accompanying drawing.
With reference to accompanying drawing, this pair of cavity liner perforating bullet, fixedly connected with screw thread between the deep penetrating perforating unit that constitutes by deep penetration powder column 2, taper deep penetration cavity liner 3, deep penetration body 4 and form, deep penetration body and large aperture body by the perforation unit, large aperture that large aperture powder column 5, arc large aperture cavity liner 6, large aperture body 7 constitute.Being equipped with by cross sectional shape on the deep penetration body is the propagation of explosion unit that intermediate 8, booster gains 9 and the taper propagation of explosion cavity liner 10 of right-angled triangle constitutes.The two ends of booster gains are connected with the large aperture powder column with the deep penetration powder column respectively, and the two ends of propagation of explosion cavity liner are connected with the large aperture cavity liner with the deep penetration cavity liner respectively.Be provided with propagation of explosion hole 11 and the detonating fuse groove 12 that is connected with the deep penetration powder column on the top of deep penetration body.
This pair of simple in structure, the handling ease of cavity liner perforating bullet, deep penetrating perforating unit and perforation unit, large aperture all adopt the prior art processing and fabricating, again taper propagation of explosion cavity liner, booster gains and intermediate are compressed on and are made into integration the propagation of explosion unit, successively three parts are assembled into one then and get final product.
What Fig. 2 provided is the user mode structural representation that two two cavity liner perforating bullets 1 are housed in perforating gun 01.During operation, two cavity liner perforating bullets are contained in the firing mount 03 by phase sequence, again detonating fuse 02 is wrapped in outside the firing mount and in the detonating fuse groove of each two cavity liner perforating bullet and passes and be fixed in the detonating fuse groove, the firing mount of filling two cavity liner perforating bullets is packed in the perforating gun, carry out perforating job then routinely.
Inner on probation the demonstration, the utility model preferably resolves the problem that deep penetration and large aperture can not take into account simultaneously in the perforating job, effectively enlarged the flowing space of crude oil, improved the crude output of individual well greatly, reach the purpose that improves oil recovery efficiency, incremental oil production, be subjected to trier's favorable comment.
