(5) СПОСОБ ИЗОЛЯЦМИ ПЛАСТОВЫХ ВОД В НЕФТЯНОЙ СКВАЖИНЕ(5) METHOD FOR INSULATING WATER INSULATION IN OIL WELL
1one
Изобретение относитс к изол ции, водоносных пластов при эксплуатации нефт ных месторождений.The invention relates to the isolation of aquifers in the exploitation of oil fields.
Известен способ изол ции водоносных пропластов путем закачки в них дихлорполидиорганоксиланов и органотрихлорсиланов 1.A known method for isolating aquifer proplasts by injecting dichloropolydiorganoxylanes and organotrichlorosilanes 1 into them.
Однако этот способ недостаточно эффективен, а используемые вещества дорогосто щи.,QHowever, this method is not effective enough, and the substances used are expensive., Q
Известен способ изол ции пластовых вод в нефт ной скважине путем закачки в призабойную зону силанов 2..There is a method for isolating formation waters in an oil well by pumping silanes 2 into the bottomhole zone.
Известный способ также недостаточно эффективен.15The known method is also not effective enough.
Цель изобретени - повыцение эффективности изол ции.The purpose of the invention is to increase the efficiency of the insulation.
Указанна цель достигаетс тем-, что в качестве силанов используют силаны 20 общей формулы SipH n- Способ осуществл ют следующим образом .This goal is achieved by using silanes 20 of the general formula SipH n-as silanes. The method is carried out as follows.
В скважину нагнетают силаны - соединени кремни и водорода общей формулы Sif, Н2р+2.Силаны не реагируют с нефтью , но активно вступают в реакцию с пластовой водой, образу малорастворимые или нерастворимые соединени , которые закупоривают поры и трещины водоносных пропластов. Нефтеносные пропласты при этом не утрачивают фильтрационных свойств.Silanes are injected into the well - silicon and hydrogen compounds of the general formula Sif, H2p + 2. Silanes do not react with oil, but actively react with formation water to form poorly soluble or insoluble compounds that clog the pores and cracks of aquifers. Oil-bearing plastics do not lose their filtration properties.
Силаны содержат некоторые отходы производства, например, в отходах производства аэросила содержитс до 2030% силанов. Силаны могут быть извлечены из этих отходов, что удешевл ет их использование.Silanes contain some production wastes, for example, up to 2030% of silanes are contained in aerosil production wastes. Silanes can be recovered from this waste, which makes it cheaper to use.
В лабораторных услови х испытывалось вли ние силанов на изменение проницаемости песчаников, содержащих воду или нефть.Under laboratory conditions, the effect of silanes on changes in the permeability of sandstones containing water or oil was tested.
При общей пористости песчаников на полную цементацию 1 м водонос396 41With a total porosity of sandstones at full cementation of 1 m water bearing 396
ной породы расход реагента составил 1,5 течение 15 мин. Газообразные силены нагнетались в породу под давлением 3 атм.Noah breed reagent consumption was 1.5 for 15 minutes. Gaseous silences were injected into the rock under a pressure of 3 atm.
Результаты приведены втаблице.The results are shown in the table.
Аналогичные результаты получены и дл терригенных коллекторов с более высокой проницаемостью и пористостью .,10Similar results were obtained for terrigenous reservoirs with higher permeability and porosity., 10
