FIELD: oil and gas industry.SUBSTANCE: invention is referred to the sphere of operation of multipurpose wells, mainly to sandy oil wells, and is intended for treatment of the formation fluid from sand and mechanical impurities. The method for removal of sand and mechanical impurities in a flow of oil, water and gas includes catchment of sand from a flow of oil, water and gas, accumulation of sand and mechanical impurities in receiving hoppers. Catchment of sand and mechanical impurities from a flow of oil, water and gas is implemented mechanically due to reduced pressure and shock losses based on Bord effect intensified by Coanda effect and assumes installation in a flow of oil, water and gas the device design consisting of sand and mechanical impurities receiving hopper and pressure differentiator, which mechanical specifications allow maximum development of the above effects. The device may be installed in a pumped flow or a flow moved by own pressure both upwards and downwards any pumping mechanisms, at that it is envisaged to install one or several in series devices for complete treatment of a flow of oil, water and gas from sand and mechanical impurities.EFFECT: reliable catchment of sand and mechanical impurities in a flow of oil, water and gas.1 dwg |
