The article discusses the advantages of using cryogenic technology in the production of gravel filter elements. A method for calculating the main components for the production of temporarily monolithic annular gravel elements is described. An approach has been developed for the strength analysis of annular gravel filter bits, taking into account installation conditions and the effect of water flow in the aquifer. An analytical calculation was performed to determine the distribution of gravel packing in the behind-...

Asphalt-resin-paraffin deposits (ARPD) are a complex dispersed system formed by substances that have separated from the oil phase according to various signs. The sediments include asphaltenes, resins, paraffins, liquid hydrocarbons, mechanical impurities and water. In conditions of intensive deposition of ARPD, normal operation of wells is impossible without carrying out work using dewaxing equipment. The purpose of the treatment is the use of chemical reagents in the composition of the emulsion to affect the bott...
