Description

Предлагаемый способ определени  водонефт ного контакта отличаетс  от известных тем, что при его применении производ т дополнительную перфорацию обсадных труб против нижней части пласта, ниже водонефт ного контакта, спускают фоитанные трубы с заглушкой внутри на уровне пакера и окнами непосредственно под пакером и против нижних перфорационных отверстий, ниже заглушки помещают регистрирующий прибор (уровнемер или, дифманометр). Это обеспечивает повышение точности измерений.The proposed method for determining the water-oil contact differs from the known ones in that it uses additional perforation of the casing against the lower part of the reservoir, below the water-oil contact, flatten pipes with a plug inside at the level of the packer and windows directly under the packer and against the lower perforations , below the stub place the recording device (level gauge or differential meter). This provides improved measurement accuracy.

На чертеже изображена схема забо  и призабойной зоны при определении водонефт ного контакта по предлагаемому способу.The drawing shows a diagram of the bottomhole zone and the bottomhole zone when determining the water-oil contact using the proposed method.

Сущность описываемого способа определени  отметки водонефт ного контакта заключаетс  в следующем.The essence of the described method for determining the mark of water-oil contact is as follows.

Производитс  дополнительна  перфораци  1 обсадных труб 2 против нижней части пласта, заведомо ниже водонефт ного контакта. Выа;г верхних отверстий перфорации между обсадными трубами 2 и фонтанными трубами 3 устанавливаетс  пакер 4. В фонтанных трубах 3, на которых закреплен пакер 4, предусматриваетс  на уровне пакера заглушка 5. Поэтому после установки пакера забой полностью изолируетс  от верхней части ствола. Наход ща с  ниже заглушки 5 фонтанна  труба 3 имеет окна 6 в верхней и нижней част х.An additional perforation of 1 casing 2 against the lower part of the reservoir is made, which is obviously below the water-oil contact. The upper holes of the perforation between the casing 2 and the flow pipes 3 is installed packer 4. In the flow pipes 3, on which the packer 4 is fixed, plug 5 is provided at the level of the packer 5. Therefore, after installing the packer, the bottom is completely isolated from the top of the barrel. The fountain pipe 3 located below the plug 5 has windows 6 in the upper and lower parts.

Перед спуском фонтанных труб в наход щуюс  ниже заглушки фонтанную трубу помещаетс  регистрирующий прибор 7 (уровнемер, дифманометр ) , с помощью которого фиксируют изменение во времени уровн  раздела вода - нефть.Before lowering the flow tubes, a recording device 7 (level gauge, differential pressure gauge) is placed into the flow tube located below the plug, with which the change in the water-oil separation level with time is recorded.

№ 150450No. 150450

Возможность определени  раздела вода - нефть в пласте по разделу вода - нефть в скважине основана на том, что последний в пределе устанавливаетс  на том же уровне, что и раздел вода - нефть в районе, скважины. Полученна  крива , после подъема прибора вместе с колонной труб, используетс  дл  установлени  отметки водонефт ного контакта в районе скважины.The ability to determine the water - oil in the reservoir section by the water - oil section in the well is based on the fact that the latter is set at the same level as the water - oil section in the area, well. The resulting curve, after lifting the instrument together with the pipe string, is used to establish the mark of water-oil contact in the area of the well.

Предмет изобретени Subject invention

Способ определени  водопефт ного контакта в нефт ной скважине, отличающийс  тем, что, с целью повышени  точности измерений, производ т дополнительную перфорацию обсадных труб, против нижней части пласта, ниже водонефт ного контакта, спускают фонтанные трубы с заглушкой внутри на уровне пакера и окнами непосредственно под пакером и против нижних перфорационных отверстий, ниже заглушки помеш,ают регистрируюш,ий прибор (уровнемер или дифманометр).The method of determining the water-oil contact in an oil well, characterized in that, in order to improve measurement accuracy, additional perforation of the casing is performed, against the lower part of the reservoir, below the water-oil contact, lower flow pipes with a plug inside at the level of the packer and windows directly under the packer and against the lower perforations, below the cap you can move, register with a device (level gauge or differential pressure gauge).
