Abstract: Использование: в горной промышленности и, в частности при строительстве газовых газоконденсатных и нефтяных скважин. Обеспечивает повышение эффективности способа заканчивания скважин при одновременном уменьшении степени загрязнения вскрываемого продуктивного пласта, сокращения сроков его осуществления и расхода химических реагентов, глины, утяжелителя, воды, тепла, энергии и т.п. Сущность изобретения: внутрь зацементированной эксплуатационной колонны, заполненной продавочной жидкостью, спускают колонну насосно-компрессорных труб. Производят установку фонтанной арматуры (ФА). Обвязывают ее манифольдом и герметизируют устье. Заменяют продавочную жидкость на воду. На буфере ФА монтируют лубрикатор. Производят опрессовку устья, для чего в затрубное пространство (ЗП) нагнетают компрессором сжатый воздух. Затем его дожимают до требуемого давления водой. Ее закачивают в трубный канал (ТК) с помощью насосного агрегата. После окончания опрессовки устья опрессовывают лубрикатор. Для этого его внутреннюю полость сообщают с ТК. После опрессовки лубрикатора ТК перекрывают. После этого перепускают сжатый воздух из ЗП в ТК по манифольду ФА. Затем снижают величину избыточного давления сжатого воздуха путем стравливания его в атмосферу. ТК и ЗП после этого разобщают. Перфораторы спускают в эксплуатационную колонну через лубрикатор и колонну насосно-компрессорных труб. Производят перфорацию эксплуатационной колонны и перфораторы поднимают на устье. Освоение скважины начинают с плавного снижения избыточного давления в ЗП, путем его сообщения с атмосферой. После этого ЗП перекрывают и начинают плавно снижать избыточное давление в ТК, путем его сообщения с атмосферой. После освоения скважины ее продувают через ТК для полной очистки призабойной зоны. Далее переходят к исследованию скважины. 3 з. п.ф-лы.

Abstract: FIELD: bore-hole drilling equipment and machinery. SUBSTANCE: this can be used for drilling inclined and deep horizontal bore-hole at high bottom-hole temperatures. Located in turbo-drill body is turbine. Connected with turbine is reduction unit having input and output shafts and gear transmission. Also provided is spindle with axial and radial supports on shaft. Output shaft of reduction unit is connected with spindle shaft through torsion shaft. Bodies of reduction unit and spindle are connected through adapter. Torsion shaft is embraced by protective bush with clearance. Protective bush creates circular clearance with inner surface of adapter. Reduction unit, torsion shaft and spindle supports are installed in common oil-filled chamber which is made hermetically tight by seals. Drilling fluid passes through circular passage inside bodies of turbine, reduction unit, spindle and adapter. Shafts and transmission components are protected from overloads by torsion due to its resilient pliability. In application of adapter with misaligned axes, torsion shaft is coupled with adjacent shaft ball joints. Protective bush is provided with sealing members which allow for angular displacement of bodies without disturbing tightness. In this case, torsion shaft functions as universal-joint shaft, and reduction-unit turbo-drill functions as whipstock. Aforesaid embodiment allows for reduction of dynamic loads brought to bear on shafts and components of turbo-drill, and enlarges potentiality of control over bore-hole trajectory.

Abstract: FIELD: armament, in particular, systems providing for preparation and execution of salvo launch of homing ammunition (for instance, anti-tank missiles) at area (multiple) targets with destruction objects dispersed inside them (tanks, self-propelled rocket launchers, etc). SUBSTANCE: the device uses a unit that receives information on target position, ammunition launch control signal generating unit, launch tactical control unit, unit computing the difference between the width of the homing head vision zone at the ammunition flight altitude. The tactical control unit uses a firing interval setter, register of ammunition assigned to firing, lateral deviation increment information storage register, two adders. After the analysis of the obtained information on the target nature the launcher commander selects the respective quantity of ammunition required for destruction of the target and introduces it in the register of ammunition assigned to firing. If the width of the area (multiple) target exceeds the width of the homing head vision zone, the commander selects the lateral deviation increment values and enters it in the lateral deviation increment information register, which in the process of salvo launch is cyclically summed up in the two adders with a positive and negative sign. The accumulated values of increments are successively introduced in the lateral deviation setter of the ammunition control systems and after a certain time determined by the delay units the engines are started. EFFECT: automatic separation of ammunition in front by successive increase of lateral deviation of launched ammunition to the left or right of the target center. 2 dwg
