Description

Изобретение относитс  к нефтедобывающей промышленности, в частности к способам обработки призабойной зоны нефт ных скважин дл  повышени  их производительности.The invention relates to the oil industry, in particular to methods for treating the wellbore zone of oil wells in order to increase their productivity.

Известен способ обработки призабойной зоны смесью сжиженных нефт ных газов - пропана и бутана f .The known method of processing the bottomhole zone with a mixture of liquefied petroleum gases — propane and butane f.

Способ недостаточно эффективен из-за смешиваемости газов с пластовой нефтью. ./The method is not effective enough due to the miscibility of gases with reservoir oil. ./

Известен способ обработки призз-бойной зоны путем закачки в нее растворител  - алкилэфира и извлечени  на поверхность продуктов реакции A known method of treating a prism zone is by pumping a solvent alkyl ester into it and extracting the reaction products to the surface.

Данный способ не позвол ет эффективно очистить призабойную зону скважины .This method does not effectively clean the wellbore zone.

Цель изобретени  - повышение эффективности ее обработки за счет улучшени  очистки призабойной зоны.The purpose of the invention is to increase the efficiency of its treatment by improving the cleaning of the bottomhole zone.

Указанна  цель достигаетс  тем, что в качестве растворител  используют органохлорсиланы в ацетоне. This goal is achieved by using organochlorosilanes in acetone as the solvent.

Принципиальным отличием.органохлорсиланов  вл етс  их способность вступать в химическое взаимодействие с горной породой и пластовой водой (реакци  гидролиза). В результате аг The principal difference between organochlorosilanes is their ability to react chemically with rock and formation water (hydrolysis reaction). As a result ag

кого химического -взаимодействи  платова  вода удал етс  с забо  сква- жины (расходуетс  на реакцию гидролза ), что совместно с осушгиоиим дей ствием ацетона способствует эффективной осушке призабойной зоны пласта и увеличению проницаемости дл  нефти.The chemical interaction of the board water is removed from the well (consumed in the hydrolysis reaction), which, together with the drying action of acetone, contributes to the effective drying of the bottomhole formation zone and an increase in the permeability to oil.

Доставленные в пласт органохлорсиланы удерживаютс  в пор дке не слабыми адсорбционными силами, а химическими св з ми, что способствует увеличению длительности эффекта от обработок. Это св зано со способностью органохлорсилаиов вступать во взаимодействие с гидроксилвными группами горной ПОРОДЫ, например гидроксильными группами кристаллогидратов , с образованием прочных элементосйлоксановых св зей.Organochlorosilanes delivered to the reservoir are held in order, not by weak adsorption forces, but by chemical bonds, which contributes to an increase in the duration of the effect of the treatments. This is due to the ability of organochlorosilides to interact with hydroxyl groups of mountain BREED, such as hydroxyl groups of crystalline hydrates, to form strong elementalloxane bonds.
