Abstract
The utility model discloses a conveying type tubing gun perforator for perforating and breaking of an underground oil reservoir in an oil production well. The gun perforator consists of a detonation transmitting joint, a perforating bullet rack, a detonating joint, a positioning disk, a righting sleeve, a sealing ring, a stopping ring, a retaining flake and so on. The structure and connection relationship of the utility model are characterized in that the detonation transmitting joint is used for connecting an upper and a lower perforating bullet rack components; the perforating bullet rack is used for loading perforating bullets on and connecting a detonation guiding wire; the positioning disk is arranged on the top of the perforating bullet rack section at the uppermost end. After a detonation transmitting pipe is clamped at the two ends of the detonation guiding wire in connection with a perforating bullet, the retaining flake and the stopping ring are employed to fix the detonation transmitting pipe in the central hole of the positioning disk, the righting sleeve is used to centralize and right the detonation transmitting pipe to the central hole, and then the detonating joint is arranged on the upper part of the detonation transmitting pipe and connected to the detonation transmitting joint at the lower part. The utility model has the advantages of excellent temperature and pressure resistant properties, high detonation transmitting efficiency as well as blind zone reducing ability.
Description
The utility model is a kind ofly in producing well underground oil reservoir to be implemented perforation, made the tubing conveyed perforation (tcp) device that splits, and it relates to improvement on existing apparatus structure and the performance and raising.
The effect of perforation is to penetrate sleeve pipe, the cement sheath of wearing down-hole sealing layer of oil gas production and go deep into oil-gas Layer in the oil recovery process, forms the fluid passage of linking up pit shaft and layer of oil gas production.For efficient and the precision that improves the perforation of once going into the well, be according to the thickness of oil well oil reservoir, the difference of the number of plies, perforating bullet is fixedly mounted on the firing mount on the different aspects as required, once penetrate the purpose of opening whole oil reservoirs of waiting to penetrate oil well thereby reach.But heatproof, the resistance to pressure of present equipment are relatively poor, and the propagation of explosion rate is also lower, and the blind area reaches 40 centimetres, and these shortcomings have all greatly hindered the production exploitation to oil well.
The purpose of this utility model designs at the existing problem of above-mentioned present equipment just a kind of tubing conveyed perforation (tcp) of new structure device is provided, according to the thickness of oil well oil reservoir, the difference of the number of plies, with perforating bullet be fixedly mounted on as required split separately firing mount on, and utilize reliable transmission detonation joint to connect these firing mounts successively, once penetrate the purpose of opening whole oil reservoirs of waiting to penetrate oil well thereby reach.It has heatproof, good pressure-resistant performance, and propagation of explosion efficient height reduces advantages such as blind area.
The purpose of this utility model realizes by following measure:
This kind tubing conveyed perforation (tcp) device, it is by transmission detonation joint, the perforation firing mount, priming adapter, positioning disk, supporting positive cover, sealing ring, assemblies such as retaining ring and catch constitute, its structure and connection features are, transmission detonation joint is used to connect two sections perforating bullet frame component, at the top that is in perforation firing mount section topmost positioning disk is installed, on the two ends card of the detonating fuse that will connect with perforating bullet behind the detonating primer, detonating primer is fixedly installed in the centre bore of positioning disk with catch and retaining ring, with supporting positive cover that detonating primer is placed in the middle with respect to this centre bore again, align, priming adapter is installed at an upper portion thereof again and connects the transmission detonation joint of bottom.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of the utility model device
Below with reference to drawings and Examples the utility model is further described:
Shown in attached 1, this kind tubing conveyed perforation (tcp) device, it is to be made of assemblies such as transmission detonation joint 1, perforation firing mount 2, priming adapter 12, positioning disk 8, supporting positive cover 6, sealing ring 11, retaining ring 4 and catch 9, wherein, transmission detonation joint 1 is used to connect two sections perforation firing mount 2 assemblies, perforation firing mount 2 is used to adorn perforating bullet 3 and connects detonating fuse 5, like this, this kind perforator just can be configured to by the multistage perforating bullet, form and be connected all easily, but also can satisfy the different requirements of the underground aspect of oil well.In addition, at the top that is in 2 sections of perforation firing mounts topmost positioning disk 8 is installed, after being fixed in the perforation firing mount 2 by different perforation designing requirements perforating bullet 3, the detonating fuse 5 that will connect with perforating bullet 3 priming cake of back and perforating bullet on the firing mount connects, then with detonating primer 7 on the two ends card of detonating fuse, to block good detonating primer 7 with catch 9 and retaining ring 4 is fixedly installed in the centre bore of positioning disk 8, use supporting positive cover 6 that detonating primer 7 is placed in the middle with respect to this centre bore again, align, be fixed with fixing pin 10 and sealing ring 11 again, at last, priming adapter 12 and connect the transmission detonation joint 1 of bottom is installed at an upper portion thereof.Again transmission detonation joint is connected with next perforation firing mount.
The utility model device heatproof, resistance to pressure are good, and heatproof can reach 220 ℃, and withstand voltage 80MP can disposable penetrate out the oil reservoir whole to be penetrated of oil well, and can make the propagation of explosion rate reach 100%, has reduced the blind area simultaneously, and the blind area is 13 centimetres.This installs easy operating, has improved production efficiency.
