FIELD: equipment and technology of recovery of well product from well. SUBSTANCE: process includes sinking of tools and tubing string into well, expansion of coupling channels of pool by fluid, their filling up with filtering material, installation of well and gravelsand filters and provoking inflow of gas into well. Salient feature of process lies in conducting this work with single sinking-lifting operation of tubing string and without any time breaks. With this in mind sunk equipment is fitted with set of well filter and combined circulation valve with holes to wash out surplus of filtering material, with bushing shutting off these holes and clearing space of well filter to provoke inflow of gas. EFFECT: prolonged usage of productive horizons containing siltstones. 2 dwg
