Abstract
Sand flow ing of o il w ell or gas w ell has som e bad influences on the production and techno logy. M o re severely, it can destroy thew e l.l In order to assure the production and to design rational wo rk system, th is paper studies the sand go-dow n regu la tion in current and ca lcu la tes the cr itica l ve locity and critical vo lum e based on two-phase flow ing theory. A t the sam e tim e, th is pape r ver ifies the ca lculated resu lt by fie ld data, w hich can so lve the sand-carry ing prob lem of gas w ell and prov ide a scien tific ev idence for the gas production.
