Afterwards the powder pressure generator is run in to the well at the logging cable below the loading hopper to the interval of the productive stratum. Voltage is supplied through the logging cable to glowing filaments set in powder charges. Powder charges are ignited thus ensuring mechanical, thermal, physical and chemical impact on the productive stratum. Time delay is held upon treatment of the productive stratum. Then unburnt parts of the powder pressure generator are lifted at the logging cable through the loading hopper to the lubricator, the gate valve is closed, the pressure-balancing valve is open. Inside the lubricator pressure is balanced to the atmospheric pressure and then the lubricator is disconnected. At that the loading hopper is designed to protect the packer during powder charges burning, and the time delay upon treatment of the productive stratum shall be not less than five minutes. |

Invention relates to compositions for obtaining electroconductive coatings on substrates surface. Described is a printing composition for obtaining the electroconductive coatings based on silver particles dispersed in water. The composition contains: a) from 5 to 40 wt.p. of metal silver particles with an effective diameter from 10 to 150 nm, with the silver particles having bimodal distribution of particles by sizes; from 50 to 99.5 wt.p. of water and, if necessary, to 30 wt.p. of a solvent; c) from 0.01 to 15 wt.p. of a dispersing agent; d) from 0 to 5 wt.p of additives; e) from 0 to 5 wt.p. of electroconductive, if necessary, water-soluble, polymers; f) from o.5 to 5 wt.p. of a thickening agent; g) from 30 to 70 wt.p. of silver particles or silver-coated copper particles with an effective diameter from 500 nm to 10 mcm. The composition has a viscosity, at least, 1 Pa·s. Also described is the application of the composition for obtaining the electroconductive coatings, method of obtaining current-conductive paths and a polymer substrate with the electroconductive coating from the claimed composition. |

Arrangement of inserts with fixed cutters at drill bit to decrease cracking of diamond plates Invention relates to vaned drill bit for rotary drilling. Proposed drill bit comprises body with end surface and axis, at least one vane with leading and trailing edges extending in lengthwise and radial direction outward above drill bit body end surface and several primary cutters. The latter include at least one main cutter with cutting surface. One part of the latter is covered by the part of at least one vane extending at least partially from at least one vane. It is arranged to follow the cutting path at drill bit body spinning around axis to grip the ore at motion in cutting path. Part of one vane leading edge has a skew extending over its outer surface. |
