Description
(Б ) УСТРОЙСТВО дл ИСПЫТАНИЯ ПЛАСТОВ(B) DEVICE FOR PLASTIC TESTS
tt
Изобретение относитс к нефтегазодобывающей промышленности, а именно к устройствам дл испытани скважин.The invention relates to the oil and gas industry, namely, well testing devices.
Известно устройство дл испытани скважин, включающее выполненный из секций фильтр с герметизирующими элементами, раздел ющими секции.A well testing apparatus is known, comprising a sectional filter with sealing elements separating the sections.
Устройство позвол ет производить испытание нескольких горизонтов в многопластовых скважинах с одновременной постановкой мостовых пакерт пробок за один спуск инструмента uThe device allows to test several horizons in multi-layer wells with simultaneous setting of bridge packer plugs in one descent of the tool u
Недостатком устройства вл етс то, что пласты испытываютс последовательно снизу вверх {это требует значительных затрат времени) и после каждого испытани требуетс спуск специального инструмента дл извлечени пакер-пробок.The drawback of the device is that the formations are tested sequentially from bottom to top (this requires a considerable amount of time) and after each test a special tool is required to release the packer plugs.
Известно также устройство дл испытани пластов, спускаемое на колон не труб, включающее впускной клапан, фильтр, выполненный в виде секций с герметизирующими элементами, раздел ющими испытуемую зону на участки, и установленные в каждой секции индикаторы притока Г 21,It is also known a device for testing formations that is lowered onto a non-tubular column, includes an inlet valve, a filter made in sections with sealing elements dividing the test area into sections, and flow indicators G 21 installed in each section,
Однако устройство не позвол ет испытать одновременно несколько пластов с определением продуктивности каждого из пластов.However, the device does not allow testing several layers simultaneously with determining the productivity of each of the layers.
Цель изобретени - повышение точности испытани за счет вы влени продуктивных и непродуктивных участков пласта.The purpose of the invention is to improve the accuracy of testing due to the detection of productive and unproductive areas of the reservoir.
Поставленна цель достигаетс тем, что секции фильтра телескопически св заны друг с другом, разделены седлами, в которых установлены The goal is achieved by the fact that the filter sections are telescopically connected to each other, separated by seats, in which
15 поплавковые затворы, св занные с индикаторами притока.15 float valves associated with inflow indicators.
На фиг. 1 показано устройство дл испытани пластов, транспортное положение; на фиг. 2 - то же, при FIG. 1 shows a formation testing device, transport position; in fig. 2 - the same as
20 установке в скважине; на фиг. 3 то же, рабочее положение.20 installation in the well; in fig. 3 is the same working position.
