Description
Изобретение относитс к добыче нефти и газа, а именно к устройствам дл воздействи на прпзабойную зону скважиFIELD OF THE INVENTION The invention relates to the extraction of oil and gas, namely, devices for influencing the well bottom zone.
Известно устройство дл очистки поверхностей воздействием электрогкдравлических ударных волн, состо щее на генератора импу ьсньгх токов кабел и cHcreivibi электродов ij .A device for cleaning surfaces by electro-hydraulic shock waves is known, consisting of a generator of impulse current of a cable and cHcreivibi electrodes ij.
Однако известное устройство отличаерс неаостагочно эффективным воздействием вследствие незначительной направленности ударных волн.However, the known device otlichaers non-aggressive effective impact due to the small directionality of the shock waves.
Известно устройство дл воздействи на призабойную зону скважин, включающее корпус, генератор импульсов тока, соединеннь й с коаксиальной системой электродов через трос-кабель .A device is known for influencing the well bottom zone, including a housing, a current pulse generator connected to a coaxial system of electrodes through a cable-cable.
Но и такое устройство отличаетс низкой эффективностью воздействи на призабойную зону скважин.But such a device is also characterized by a low efficiency of impact on the well bottom zone.
Цель изобретени - повышение эффективности воздействи на призабойную зону скважин путем увеличени направленности ударных волн.The purpose of the invention is to increase the efficiency of the impact on the wellbore zone by increasing the directionality of the shock waves.
Указа: пак цель достигаетс тем, что конце грг.чтго с осью системьг электродов на ее иентоальтгом электроде установлен Электре: лагкнг.Decree: the pack goal is achieved by the fact that Electra: Lagng is installed on the end of the grg.
а чертеже показана схе.ма устройстваThe drawing shows the circuit device
УстосйсчБо чостонт на лебедки 1, генератора 2 .угь;ов тока, соединенного через трое-КЗбель 3 с центральным электродом 4, на котором помешена обмотка электрсмагнита 5.Use of a winder 1, generator 2 .gr; o the current connected through three-КЗбель 3 to the central electrode 4, on which the electromagnet 5 winding is placed.
Последний соединен с трос-кабелем 3 через сопроткв,тепЕе 6.The latter is connected to the cable-cable 3 through the samotkv, now 6.
Отрпцателькь5ми электродами 7 вл ютс выступы 3 корпусе 8, где также имеютс кана.г1Ь 9 с соплами Ю.The electrode electrodes 7 are the protrusions 3 of the housing 8, where there are also canals with 9 nozzles.
Устройство работает следующим образом .The device works as follows.
Перед началом работы внугрискважинную часть устройства спускают с помошью лебедки 1 на трос-кабеле 3 в призабойкую зону сква си15ы. От генератора 2 на систему электродов подаетс импульс тока , и между влектродакш 4 н 7 происходит электрический разр д, который соеBefore starting work, the downhole part of the device is lowered with the help of the winch 1 on the cable-cable 3 into the wellbore zone of the well. From the generator 2, a current pulse is applied to the electrode system, and an electrical discharge occurs between the plug-in converter 4 and 7, which
