Description
(54) СПОСОБ ОПРЕДЕЛЕНИЯ МЕЖПЛАСТОВЫХ ПЕРЕТОКОВ НЕФТИ(54) METHOD FOR DETERMINING INTER-PLASTIC OIL FLOWS
1one
Изобретение относитс к промыспово- геофизическим и геохимическим методам исследовани скважин.The invention relates to field geophysical and geochemical well survey methods.
Известны способы определени межила- стовых перетоков нефти путем отбора проб и установлени перетока по увеличенному содержанию газовых компонентов пробы.Известные способы обладают йедсста-™ точной надежностью в определении переток нефти, особенно в пласты, заводненные пресной водой.Methods are known for determining inter-aerial flow of oil by sampling and establishing a flow according to the increased content of sample gas components. The known methods have precise reliability in determining the flow of oil, especially into freshwater-forced reservoirs.
Предлагаемый способ отличаетс от известных TeiM, что определфот коэффициент пластового объема жидкости и содержание водорода в газовой фазе непосредственно после вскрыти пластов и в процессе их эксплуатации, причем наличие перетока неф ти устанавливают по одновременному увеличению текущего значени коэффициента пластового объема жидкости и содержани водорода.The proposed method differs from the known TeiM that the coefficient of the reservoir fluid volume and the hydrogen content in the gas phase are determined immediately after the reservoir has been opened and in operation, and the presence of oil flow is established by simultaneously increasing the current value of the reservoir fluid volume and hydrogen content.
Это позвол ет существенно повысить надежность вы влени перетоков нефти в заводненные пресной водой пласты.This makes it possible to significantly increase the reliability of the detection of oil flows into freshwater wilted beds.

В случае перетока нефти в заводненные закачиваемой пресной водой пласты за счет растворени газа в воде измен етс величина коэффициента пластового объема жидкости В ы,, .котора значительно повыщаетс при увеличении объема нефти в обводненном пласте. Кроме , в составе газа по вл ютс непредельные тлеводороды и водород. Последний по в,п етс поц в-оздействием суль- фатвосстанавливающих. бактерий и углерод- окисл ющих микроорганизмов, Которыми богать пресные нагнетаемые воды гидро- карбонатносульфатнонатриевого типа. При этом происходит окисление т желых угле- водородов с одновременным разложением последних, образование непредельных углеводородов и выделение водорода по следующей схеме:In the case of the flow of oil into the watering of the injected fresh water reservoirs, due to the dissolution of gas in water, the value of the coefficient of reservoir volume of the fluid Vyc which changes significantly increases with the volume of oil in the watered formation. In addition, unsaturated hydrocarbons and hydrogen appear in the composition of the gas. Last in, out is the effect of sulfate reducing agents. bacteria and carbon-oxidizing microorganisms, which are rich in fresh hydrocarbon-sulfate-sodium-type injected water. When this occurs, the oxidation of heavy hydrocarbons with simultaneous decomposition of the latter, the formation of unsaturated hydrocarbons and the release of hydrogen follows the following scheme:
