The device goes down in a chink on a cable of type KG-3-60-180, by the special device is fixed in a column on an axis.
By means of a mill, and a set of chisel plugs and as own mini the chisel pump drilling of an operational column, then a cement stone and breed is made. As ot-mechalos above, the channel in diameter of 20 mm is created., as external diameter of chisel plugs of 14 mm., there is a free space between chisel plugs and channel walls on 3 mm. On the party(side). After drilling, on command from a control panel, the device acts in film from clamps(fixing agents), the cable tension cuts off last chisel plug. The column of chisel plugs, together with a mill, remains in a layer, and the device rises on a mouth.
After lifting replacement of the empty cartridge on new, charged by chisel plugs is made. The device goes down in a chink and operation on drilling of the following channel repeats.
UFPK-1 Is the device intended for secondary opening oil and gas saturations of layers and creation of hydraulic communication (connection) between a layer and an operational columned chink. As a result of drilling in breed the channel in diameter 20 mm is created. And long 1000 mm. With the filtration area 6280 mm2.
The device works in an operational column in diameter 168 mm. Without restriction in a thickness of a wall of an operational column and in an operational column in diameter 146 mm. With thickness of a wall no more 9,0 mm.
Устройство работает в эксплуатационной колонне диаметром 168мм. без ограничения в толщине стенки эксплуатационной колонны и в эксплуатационной колонне диаметром 146мм. с толщиной стенки не более 9,0мм.
The given method of secondary opening of a layer allows:
1. To make opening of a productive layer by a so-called “sparing” method, that is without destruction of integrity of a cement stone in for a columned space.
2. To open layers with capacity (power) from 0,5 m and more.
3. To open a layer on reprisal, balance and depression.
4. To use oil or petrocontaining emulse as washing a liquid at layer drilling, excluding it (these) possibility kolmatations the channel that reduces term of an exit of chinks by a mode.
5. The control direct and indirect (graphic) methods depth of the drilled channel.
6. To create the channel strictly under 90 hailstones. Concerning an axis of a chink at the expense of rigid connection of chisel plugs.
7. To establish connection between the oil and gas saturations a layer and обсадной a column, as in the new chinks which have left drilling, and in old, being in operation, in intervals earlier both punched, and not punched.
8. To make opening of a multicolumned design of a chink, i.e. secondary opening of a layer through operational and technical columns.
At the expense of creation of extended filtrational channels possibility to put into operation not involved sites of a layer is given earlier, to receive positive dynamics on conductivity of pressure and to the skin-factor. That conducts to increase layer pressure, the debit of a chink, efficiency factor, and to reduction liquids.
Uniqueness of the given device consists also that with its (his) help probably opening of a multicolumned design, that is secondary opening of a layer through operational and technical columns.
