Abstract: Изобретение относится к области нефтегазодобывающей промышленности и может быть применено для стимуляции скважин методом гидравлического разрыва пласта. Предложен способ гидравлического разрыва пласта, включающий следующие этапы: спускают хвостовик с заколонными пакерами и равнопроходными муфтами ГРП, далее на колонне НКТ/ГНКТ спускают ключ, с помощью которого открывают муфты, при этом колонну НКТ/ГНКТ размещают над нижней муфтой, выполняют промывку заколонного интервала при открытом штуцере на поверхности и отсутствии противодавления в затрубном пространстве. Единовременно останавливают насосы и осуществляют запись кривой падения давления. На втором этапе обработки осуществляют очистку, где прокачивают рабочую жидкость ГРП для удаления остатков бурового раствора и глинистой корки, при этом выполняется этап соблюдения материального баланса, и контроль выхода жидкости на поверхность, оценивая её на содержание твердых веществ, при этом штуцер не применяется, останавливают насосы и осуществляют запись кривой падения давления. На третьем этапе производят оценку градиента давления ГРП, выполняя мини-ГРП со ступенчатым тестом, на разных расходах, при этом штуцер закрыт для определения градиента ГРП, останавливают насосы и осуществляют запись кривой падения давления. На четвертом этапе производят кислотную обработку пласта, размещая по затрубу объем кислоты, равный объему затруба открытого ствола, при закрытом штуцере на поверхности, при этом весь объем кислоты закачивают в пласт при давлении ниже давления ГРП. На пятом этапе производят гидроразрыв пласта, выполняют промывку интервала скважины от продуктов реакции кислотной обработки циркуляцией 2-3 объемов обрабатываемого интервала до выхода продуктов реакции, закрывают штуцер на поверхности и начинают закачку подушки, развивая трещину вдоль ствола скважины, закрывают штуцер на поверхности и начинают закачку рабочей жидкости ГРП, развивая трещину вдоль ствола скважины. В случае низких утечек рабочей жидкости в пласт, при низкой проницаемости коллектора и росте забойного давления, создающего риск развития трещины в высоту, обеспечивают стравливание части давления через штуцер на поверхности. При подаче проппанта в поток штуцер полностью закрывают до конца работы, останавливают насосы и осуществляют запись кривой падения давления, производят подъем разобщающего пакера и осуществляют переход на следующий интервал обработки в скважине, затем операции повторяют в той же последовательности до полного охвата всей длины скважины. Достигается технический результат – ограничение роста трещины ГРП по вертикали для обеспечения равномерной выработки продуктивных пластов и соответственно повышение нефтеотдачи пласта и в тоже время минимизация риска прорыва в выше- и нижезалегающие пласты.  8 ил.

Abstract: FIELD: medicine; ophthalmology. 
     SUBSTANCE: to select prismatic spectacles for children of preverbal age with concomitant squint, an ophthalmological examination is performed, the strength of the prism corresponding to the size of the squint is determined, the prism is placed in the intended position on the spectacle lens, followed by an assessment of the correctness of the selection of prisms and the effectiveness of prismatic correction. The selection of prisms is carried out after a complete spectacle correction of ametropia. As prisms, elastic Fresnel prisms are used with the intended strength determined using a prismatic ruler by the absence of installation movements during the cover-uncover test. The prism corresponding in strength to the size of the squint is applied to one or both spectacle lenses with the base facing in the direction opposite to the direction of the squint. In amblyopia, the prism is applied to the spectacle lens of the better-seeing eye. At the same time, visual acuity, refraction before and after cycloplegia, and the correct selection of Fresnel prisms are evaluated on a Plusoptix refractometer. The effectiveness of prismatic correction is evaluated by the appearance of binocular and stereo vision of the child using the Stereo Fly test.   
     EFFECT: method reduces the duration of the selection of prismatic spectacles for children and increases the accuracy of the selection and the effectiveness of prismatic correction.

Abstract: FIELD: engine building. 
     SUBSTANCE: invention relates to the field of engine building, namely to a two-stroke internal combustion engine, and can be used in vehicles, household machines and power engineering. The proposed two-stroke piston internal combustion engine contains a crank chamber (1), a connecting rod (2), a piston (3), a cylinder (4), a purge channel (5), an exhaust channel (6), an inlet channel (7), a spark plug ( 8), a combustion chamber (9), a check valve in the form of a curved tube (10) with pairs of inclined plates (11), which are directed towards the axis of the cylinder (4) and are inclined to the axis of the tube (10) at an angle of 30-60 degrees. The connecting rod (2) is mounted on the crankshaft (12). During the downward stroke of the piston (3), the volume of the chamber (1) decreases, the pressure in it increases, and the air-fuel mixture from it through the channel (5) enters the cylinder (4), displacing the remaining exhaust gases from it through the channel (6). The movement of this mixture into the inlet pipe is prevented by plates (11) in the curved tube (10). After the piston (3) reaches the bottom dead center, it moves up, compresses the air-fuel mixture in the cylinder (4) and reaches the top dead center position, when all the compressed air-fuel mixture is in the combustion chamber (9). During the upward movement of the piston (3), a vacuum is created in the chamber (1) and the fuel-air mixture through the tube (10) with the plates (11), which practically do not resist the flow, fills the chamber (1). At the end of the stroke of the piston (3), a high voltage is applied to the spark plug (8) upward, a spark flashes on its electrodes, the air-fuel mixture burns out with the formation of hot gases under high pressure. These gases press on the piston, which, under their action, goes down, and the cycle repeats. 
     EFFECT: increased efficiency, reliability and service life at high speed.
