Abstract
The utility model relates to a gun perforation flexible pipe extending and punching apparatus which is a well completion reforming apparatus used for the deep penetration perforation of an oil field. The gun perforation flexible pipe extending and punching apparatus is composed of a casing, a flexible pipe, a rocking rod, a screw, a press plate, a punching head and a wedge shaped block. The lateral surface of the outlet of the perforation passage of the flexible pipe in the punching head is provided with an opening. The flexible pipe can avoid a casing pipe slice which is turned over by the punching head, and the flexible pipe can successfully enter the gun perforation flexible pipe extending and punching apparatus and leave the gun perforation flexible pipe extending and punching apparatus. The perforation can be deeply penetrated. The recovery ratio for the oil field is improved.
Description
The utility model relates to oilfield deep penetration hydraulic perforating field, is that a kind of deep penetrating perforating flexible pipe stretches out hole punched device.
At present existing deep penetrating perforating device has " well penetration apparatus and the method " of U.S. PE company in China's application, application number: 86108916; American I CT company is at " mineral deposit is anodontia drilling hole device " of China application; Application number: 93212363.5; 88 years " improved hydraulia well penetration apparatus and method " in China's application.Above-mentioned deep penetrating perforating device mainly comprises hydraulic control system, punching system and hole-drilling system, and the utility model is the improvement to punching system punch structure in the above-mentioned prior art.
Fig. 3 is the punch structure schematic diagram of prior art " mineral deposit is anodontia drilling hole device ", the perforated openings that the perforation flexible pipe of this device stretches out is in the dead ahead of drift, after drift is washed sleeve pipe open like this, by the cover section of jurisdiction of being washed out may keep off positive opening 8 at the drift eyelet ' on, cause the perforation flexible pipe can't enter the stratum, and the deep penetrating perforating operation can't be finished.
The purpose of this utility model is to overcome the weak point of above-mentioned prior art, and provides a kind of deep penetrating perforating to stretch out hole punched device.
The purpose of this utility model can reach by following measure:
This device is made up of overcoat, flexible pipe, rocking bar, screw, pressing plate, drift, wedge.The outlet of its drift inner hose perforation tunnel changes lateral opening into by original front openings, and this has just avoided stopping of the cover section of jurisdiction of being washed out, and has realized that flexible pipe can pass in and out the purpose on stratum.
Flexible pipe stretches into drift by rocking bar; On rocking bar, the perforation hose passages inner surface of drift inside is excessively slick and sly to drift by pressing plate and screw, cooperates contact one wedge below the rocking bar, and puts outward and have the hole.
Because the outlet of drift inner hose passage changes lateral opening into, guaranteed that flexible pipe can successfully pass in and out the stratum, and the cover section of jurisdiction of not washed open by drift stops, reaches the purpose of deep penetrating perforating, helps improving oil recovery rate.
The drawing of accompanying drawing is described as follows:
Fig. 1 is that the perforation flexible pipe stretches out the hole punched device structural representation;
Fig. 2 is the utility model drift perspective view;
Fig. 3 prior art drift perspective view;
Fig. 4 is the generalized section of the utility model drift A-A direction;
Fig. 5 is prior art " mineral deposit is an anodontia drilling hole device " structural representation.
The utility model is described in further detail below in conjunction with accompanying drawing:
The utility model is the improvement to the prior art punch structure.
Shown in Figure 1: the utility model is made up of overcoat 1, flexible pipe 2, rocking bar 3, screw 4, pressing plate 5, drift 6, wedge 7.
Shown in Figure 2: the front end of drift is taper, and the rear end is a base, and there is a perforation flexible pipe opening 8 the bullet side, and drift inside is a hose passages.
Shown in Figure 4: the perforation hose passages inner surface of drift inside is excessively slick and sly.
Shown in Figure 5: existing device mainly by overcoat 1 ', flexible pipe 2 ', drift 6 ', wedge 7 ' form.Shown hydraulic channel 9 in the position of hole punched device and the punching system among the figure.
The utility model top connects the hole-drilling system of deep penetrating perforating device.The deep penetrating perforating device has two cover hydraulic systems, and this cover hydraulic system in the hole-drilling system directly acts on flexible pipe 2, and the another set of hydraulic system in the punching system is passed through from top to bottom, and the passage 9 that upwards returns again upwards acts on wedge 7.
During work, employ this cover hydraulic system in the punching system earlier, under the promotion of hydraulic pressure, wedge 7 moves upward, and promotion rocking bar 3, because screw 4 is with drift 6, pressing plate 5, rocking bar 3 is fixing, just promotes drift 6 and washes sleeve pipe open, after sleeve pipe is washed open, start the another set of hydraulic system of hole-drilling system, drive flexible pipe 2 and enter drift 6 under this cover hydraulic system effect, because drift 6 has lateral opening 8, and flexible pipe 2 channel inner surfaces are excessively slick and sly, therefore flexible pipe 2 is not subjected to drift 6 to wash stopping of cover section of jurisdiction open, can from the lateral opening 8 of drift 6, enter smoothly, reach the purpose of deep penetrating perforating, and can return out smoothly.
