(5) СПОСОБ ВСКРЫТИЯ ПРОДУКТИВНЫХ ПЛАСТОВ(5) METHOD OF OPENING PRODUCTIVE PLATES
1one
Изобретение относитс к способам вскрыти продуктивных пластов перфораторами и может быть использовано в нефт ной и газовой промышленности при перфорации обсадных колонн нефт ных и газовых скважин.The invention relates to methods for opening productive formations with perforators and can be used in the oil and gas industry during the perforation of casing strings of oil and gas wells.
Известен способ вскрыти пластов кумул тивными малогабаритными бескорпусными перфораторами в среде пены 1.There is a known method of opening seams with cumulative small-sized packageless perforators in the medium of foam 1.
Недостатком этого способа вл етс то, что перфорацию можно проводить лишь в пластах с аномально низкими давлени ми.The disadvantage of this method is that the perforation can only be carried out in formations with abnormally low pressures.
Известен способ вскрыти продуктивных пластов, заключающийс в создании в зоне перфорации пенной прослойки с последующей перфорацией пласта 2,There is a known method of opening productive formations, which consists in creating a foam layer in the perforation zone, followed by perforation of formation 2,
Этот способ характеризуетс невозможностью вскрыти в пенной среде продуктивного пласта с аномально высокими равнени ми без дополнительных спуско-подъемных операций.This method is characterized by the impossibility of opening the productive formation with abnormally high levels in the froth medium without additional tripping.
Целью изобретени вл етс повышение эффективности вскрыти пластов с аномально высокими давлени ми.The aim of the invention is to increase the efficiency of the opening of formations with abnormally high pressures.
Поставленна цель достигаетс тем, что создание пены и перфорацию производ т одновременно.The goal is achieved by creating foam and perforation at the same time.
На чертеже показан пример осуществлени способа вскрыти продуктивных пластов.The drawing shows an exemplary embodiment of a method for opening productive formations.
В скважину с герметизированным In the well with a sealed
10 устьем спускаетс перфоратор, снабженный электролизером. Перед перфорацией колонны 1 - посредством перфоратора 2, на цилиндрический перфорированный электрод 3. жестко св зан15 ный с перфоратором 2 через диэлектрические кольца , и на колонну 1 подаютс разноименные потенциалы от источника посто нного тока (не по„ казан). В полость,образованную поверхностью перфоратора 2 и цилиндрическим перфорированным электродом 3 засыпаетс поверхностно-активное вещество. При пропускании посто нно10 the mouth of the perforator is fitted with an electrolyzer. Before perforation of the column 1 - through the perforator 2, onto the cylindrical perforated electrode 3. rigidly connected with the perforator 2 through dielectric rings, and opposite potential of the direct current source (not shown) is fed to column 1. A surfactant is poured into the cavity formed by the surface of the perforator 2 and the cylindrical perforated electrode 3. When passing constantly
