Abstract: Изобретение относится боеприпасам огнестрельного оружия, предназначенным для поражения преимущественно подводных целей при подводной и воздушной стрельбе в воду. Кавитирующий сердечник боеприпаса огнестрельного оружия содержит головную часть, сопряженную с секущей носовой поверхностью по кавитирующей кромке, центральную и кормовую часть с глиссирующей поверхностью, предназначенной для стабилизации сердечника в каверне за счет одностороннего периодического замывания и глиссирования вдоль контура каверны. Наибольший диаметр окружности, описывающий поперечное сечение глиссирующей поверхности, определяет калибр сердечника (D). В плоскости осевого продольного сечения сердечника огибающий контур (R) поперечных сечений от кавитирующей кромки до калибра сердечника (D) ограничен зависимостью: D=d×[1+(L/d)×2π×sin ϕ/π], где: D- текущий диаметр огибающего контура (R) поперечных сечений сердечника на текущей длине (L), мм; d - диаметр кавитирующей кромки, мм; L- текущая длина сердечника, мм; ϕ=60…180° - угол раствора касательных к секущей носовой поверхности в точках ее сопряжения с кавитирующей кромкой, измеренный со стороны головной части; N=0,25…0,40 - коэффициент объема сердечника. Калибр сердечника (D) равен текущему диаметру (D) огибающего контура (R) при L=L, где L - длина от кавитирующей кромки до калибра сердечника (D). Центр масс сердечника расположен на длине X≥0,3 D перед передней кромкой глиссирующей поверхности, находящейся на длине (L). В результате повышается эффективность поражения целей за счет приближения контура (R) кавитирующего сердечника к контуру каверны (W) в воде, увеличения массы сердечника и обеспечения потери его кавитационной устойчивости с переворотом в неоднородной (гетерогенной) и сжимаемой водосодержащей среде. 6 з.п. ф-лы, 6 ил.

Abstract: FIELD: oil industry. 
     SUBSTANCE: group of inventions relates to the oil industry, namely to the production of heavy and high-viscosity oil from horizontal or inclined multi-functional wells that combine the functions of producing and injection wells, using heat due to thermochemical treatment of the oil reservoir. The well is cased with a casing pipe having the first and second opened zones on a horizontal or inclined section. The lower and upper heat-resistant packers connected by a perforated injection pipe are lowered into the well. The lower column is connected, on which a coaxially perforated fluid sampling pipe is put on. A heat-resistant separation packer that restricts the inter-pipe space is installed. The support with the built-in adjustable valve is screwed into the perforated fluid sampling pipe. The submersible pump is connected and a bypass pipe corresponding to the length of the submersible pump is inserted into the support from above. A tee is mounted on the free end of the bypass pipe and on the discharge of the submersible pump. From its opposite side, the upper column is screwed up and an additional pipe with a sealing element is introduced to the tee with an annular gap. At the end of this pipe, a tee is attached. The annular space between the casing pipe and the upper column is filled with water. In the lower part, the movement of water is limited by a heat-resistant separation packer and a built-in adjustable valve in the support. The binary composition is injected, which is fed through the annular gap, the bypass pipe and the lower column to the end section of the casing pipe. Further, the binary composition is fed through the first opened zone or the second opened zone into the preheated productive reservoir and then it is forced through with water. The calculated activation time of the exothermic chemical reaction and the heating time of the high-viscosity oil in the reservoir are maintained. The heated oil-water emulsion with unreacted reaction products is fed through the first opened zone into the inter-pipe space between the lower column and the initial section of the casing pipe and then through the built-in adjustable valve to receiver of the submersible pump. The heated oil-water emulsion is pumped to the surface through an additional pipe. When the flow rate decreases, pumping is stopped and the binary composition is re-injected into the productive zone of the reservoir along the lower column to increase the fluidity of liquid oil. Next, the pumping is carried out and the cycles are repeated. 
     EFFECT: technical result is an increase in the efficiency of high-viscosity oil production from inclined and/or horizontal wells.
