Description
Изобретение относитс к горному делу и может быть использовано при опробовании подземных формаций через скважины с применением гидромеханизации. Цель изобретени - упрощение конструкции за счет снижени количества трубопроводов . На чертеже представлено предлагаемое устройство, общий вид. Устройство состоит из трубопровода 1 с гидромониторной насадкой 2, аккумулирующей капсулы 3 с газом под высоким давлением , управл емого клапана 4, газоподвод щего патрубка 5 и газовой насадки 6. Кроме того, устройство содержит циркул ционную трубу 7 и канал 8 св зи. Капсула 3 установлена под торцом трубопровода 1 и жестко св зана с ним, при этом полость капсулы сообщена с газовой насадкой 6 через управл емый клапан 4 и газоподвод щий патрубок 5, а сама газова насадка 6 установлена концентрично гидромониторной 2. В качестве управл емого клапана 4 может быть использована люба известна конструкци , позвол юща дистанционно открывать и закрывать клапан 4. Управление приводом клапана 4 может осуществл ть с по электрическому каналу 8 св зи. Устройство работает следующим образом . Перед спуском агрегата в скважину, зна исходные технологические параметры, регулируют проходное сечение клапана 4 дл выпуска заданного объема воздуха в единицу времени. Дл опробовани нескольких скважин подготавливают р д капсул, в которых находитс воздух под давлением до 40 МПа. Размеры капсул определ ютс в зависимости от времени размыва и гидронодъема , глубины пласта, подлежащего опробованию. После этого опускают устройство, например , на глубину 200 м. Затем по каналу 8 св зи подают сигнал к приводу клапана 4, и он открываетс , при этом воздух устремл етс в полость газовой насадки 6, откуда выходит в затрубное пространство и аэрирует столб жидкости в этом пространстве. При этом гидромониторна стру находитс в воздущной оболочке за счет того, что газова насадка 6 установлена концентрично гидромониторной 2. Размываема порода выноситс из образуемой каверны в скважину и за счет эффекта эрлифтировани поднимаетс по затрубному пространству. На поверхности пульпа с воздухом поступает в дегазатор и далее в сепаратор, а очищенна вода самотеком из сепаратора - в трубопровод 1. Использование газовой капсулы обеспечивает упрощение конструкции за счет сокращени количества трубопроводов .The invention relates to mining and can be used in testing subsurface formations through wells using hydromechanization. The purpose of the invention is to simplify the design by reducing the number of pipelines. The drawing shows the proposed device, the overall appearance. The device consists of a pipeline 1 with a jetting nozzle 2, an accumulating capsule 3 with high-pressure gas, a control valve 4, a gas supplying nozzle 5 and a gas nozzle 6. In addition, the device contains a circulation pipe 7 and a communication channel 8. The capsule 3 is installed under the end of the pipeline 1 and is rigidly connected with it, with the capsule cavity communicating with the gas nozzle 6 through the control valve 4 and the gas supplying nozzle 5, and the gas nozzle 6 itself is installed concentric with the jetting 2. As the control valve 4 Any known construction can be used, allowing the valve 4 to be opened and closed remotely. Valve actuator 4 can be controlled via electrical communication channel 8. The device works as follows. Before the unit is lowered into the well, the initial technological parameters are known, they regulate the flow area of the valve 4 to release a predetermined volume of air per unit of time. In order to test several wells, a series of capsules are prepared in which the air is under pressure up to 40 MPa. The size of the capsules is determined depending on the erosion time and the hydraulic lift, the depth of the formation to be tested. After that, the device is lowered, for example, to a depth of 200 m. Then, through the communication channel 8, a signal is given to the actuator of the valve 4, and it opens, and the air rushes into the cavity of the gas nozzle 6, from where it enters the annulus and aerates the liquid column in this space. At the same time, the jetting jet is located in the air envelope due to the fact that the gas nozzle 6 is mounted concentric with the jetting unit 2. The eroded rock is carried out of the formed cavity into the well and rises through the annulus due to the air-lift effect. On the surface, the pulp with air enters the degasser and further into the separator, and the purified water by gravity from the separator goes to the pipeline 1. The use of a gas capsule simplifies the design by reducing the number of pipelines.
