Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to oil and gas industry, namely, to drilling of horizontal wells to restore open horizontal shaft. Method comprises assembly of drilling string bottomhole assembly – BHA, consisting from bottom upwards of bit, right branch pipe and calibrator, lowering to well BHA at drill string end, restoration of the barrel passability with reciprocation of the layout to normal without puffing and arranging passage of the assembly along the shaft, extraction from the well BHA, lowering the cutting head with the template to the open horizontal shaft interval, back-flushing deepening with respect to the open horizontal shaft along its entire length, preventing drill pipe string from landing in well over 5 tons of its own weight. Reservoir rock is analyzed, from which required rate of deepening and rate of liquid pumping are determined to obtain breakable particles with value which excludes build-up during pumping between BHA and well walls. Pumping rate is selected to ensure turbulent upward flow preventing particles deposition during deepening. Received parameters are used to select the downhole motor, which is installed before descent above the BHA. When deepening and removing the template and the cutting head, the liquid flow rate during direct and / or back flushing is maintained not less than providing a turbulent upward flow which eliminates precipitation of particles obtained during deepening. 
     EFFECT: reduced probability of emergency situations associated with incomplete washing of rock from horizontal borehole at direct and / or back flushing, practically to zero, expanded functionality due to possibility of use in horizontal shafts with any rock and any depth of occurrence.

Abstract: Изобретение относится к нефтегазодобывающей отрасли и предназначено для контроля натяжения ремней привода скважинных штанговых насосов. Заявлено устройство для проверки натяжения приводных ремней, содержащее корпус, шток, установленный в корпусе, нагрузочную пружину, две шкалы, нанесенные на шток. Нагрузка на шток осуществляется посредством вращения завинчивающейся крышки, которая в свою очередь давит на нагрузочную пружину, которая смещает шток. Корпус ввинчивается во втулку с возможностью контроля глубины ввинчивания, что дает возможность обеспечить плотность контакта штока с ремнем до приложения нагрузки. Снизу штока установлена возвратная пружина, причем ее жесткость меньше, чем нагрузочной. На втулку установлено шестеренчатое кольцо, которое взаимодействует с двумя опорами, на которых устанавливается устройство, путем постановки опор на шкивы. Взаимодействие опор с упомянутым кольцом происходит за счет нанесения на опоры реек. Опоры установлены на направляющие так, что при вытягивании одной опоры в одну сторону, вторая выдвигается в противоположную на то же расстояние, что и первая, что позволяет обеспечить центровку устройства. Контроль параметров нагружения осуществляется за счет упомянутых двух шкал, причем одна шкала указывает нагрузку, приложенную к штоку и, соответственно, на ремень, а вторая показывает смещения штока и, как следствие, прогиб ремня под нагрузкой. Преимуществом устройства является система автоматической центровки точки нагружения на ремне, отсутствие холостого хода штока и простота конструкции. Технический результат - повышение эффективности и надежности устройства за счет обеспечения центровки положения устройства, повышения точности измерений и упрощения конструкции. 6 ил.
