Description
;54) СПОСОБ ТЕРМИЧЕСКОП ОБРАБОТКИ ПРИЗАБОЙНОЙ ЗОНЫ НЕФТЯНОГО ПЛАСТА; 54) METHOD OF THERMAL TREATMENT OF REFRESHING ZONE OF OIL LAYER

Изобретение относитс к области нефтегазодобычи и может быть использовано при вторичных способах добычи нефти, в частности при добыче нефти путем воздействи на продуктиВЕше пласты за счет нагрева призабойной зоны скважины.The invention relates to the field of oil and gas production and can be used in secondary methods of oil production, in particular, in oil production by influencing the production of reservoirs due to the heating of the well bottom zone.
Известен способ термической обработки призабойной зоны скванмны, заключающийс в том, что в пласт закачивают металлопорошок. Затем в скважину опускают нагревательное устройство и осуществл ют прогрев призабойной зоны. Благодар повышенной теплопроводности металлопорошка высока температура,, создаваема на забое скважины, распростран етс по ориентации трещин внутрь пласта 1 .The known method of thermal treatment of the bottomhole zone of squammers is that metal powder is pumped into the formation. Then a heating device is lowered into the well and the bottom zone is heated. Due to the increased thermal conductivity of the metal powder, the high temperature that is created at the bottom of the well propagates along the orientation of the cracks inside the formation 1.
Недостатком известного способа термической обработки вл етс то, что перенос тепла осуществл етс только за счет теплопроводности металлопорошка . Кроме того, частицы металла разделены флюидом пласта, что уху;дшает процесс теплопередачи.A disadvantage of the known heat treatment method is that the heat transfer is carried out only due to the thermal conductivity of the metal powder. In addition, the metal particles are separated by a formation fluid, which is to the ear, and it is a heat transfer process.
Целью изобретени . вл етс интенсификаци прогрева пласта.The purpose of the invention. is the intensification of the warm-up formation.
Дл достижени этой цели в способе термической обработки призабойной зоны нефт ного пласта путем закачивани в пласт вместе с потоком жидкости частиц металлического материала с последующим нагревом призабойной зоны, в качестве метал.)гопорошка используют гидриды металлов, а нагревание производ тдо тем 1ературы диссоциации водорода из закаченных гидридов.To achieve this goal, in the method of heat treatment of the bottomhole zone of an oil reservoir by pumping particles of a metallic material into the reservoir together with a liquid stream, followed by heating the bottomhole zone, metal hydrides are used as metal powders, and heating is performed by dissociating hydrogen from the injected hydrides.

Способ осуществл етс следующим образом.The method is carried out as follows.
На поверхности подготавливают взвесь гидрида в жидкости, котора A hydride slurry is prepared on the surface in a liquid that
15 не вызывает разложени гидрида, например в углеводородной жидкости в воде, В качестве металлопороика используют порошки никель-лантанового гидрида, железо-никелевого 15 does not cause decomposition of the hydride, for example, in a hydrocarbon liquid in water; powders of nickel-lanthanum hydride, iron-nickel
20 гидрида, гидрида .пити , боргидрида лити , боргидрида натри и порошки других ги.цридов с температурой диссоциации во.цораца до 300-350°С. Так25 же могут быть использованы и более термостойкие гидриды.20 hydrides, hydrides, piti, lithium borohydride, sodium borohydride and powders of other hy.crides with a dissociation temperature of carbon dioxide up to 300-350 ° С. Also 25 more heat-resistant hydrides can be used.
Приготовленную суспензию гидрида закачивают в пласт. После насыщ ни 30 пласта частичками гидрида осушествл .The prepared suspension of the hydride is pumped into the reservoir. After saturating 30 formations with hydride particles
