| titleOfInvention | Borehole cyclic generator of compression pulses and method of pay permeability increase |
| abstract | FIELD: oil and gas industry. n SUBSTANCE: invention is related to oil and gas industry and area of water resources prospecting and production, in particular, to facilities of intensification of fluid inflow to wells, for instance, oil wells, for increase of production, productivity index and recovery factor. Provides possibility for arrangement and method of cyclic pressure pulses generation with required amplitude-time characteristics of pulses and provision of their localisation in surrounding space with the help of realised process of convective burning, which practices "soft" effect at well without damage of its integrity and compaction of pay rock. Device comprises body with open end, serially placed layers of mixture that includes solid fuel and hard oxidant with apparent density of loading creating charge, and igniting cap installed at body open end. At that layers of mixture have different porosity and possibility of convective burning realisation by them with different speed. n EFFECT: provision of serial convective burning of layers with creation of serially alternating compression pulses. n 7 cl, 1 dwg |
