摘要: An apparatus for improved detection of underground well kicks, preferably comprising a first acoustic sensor mounted on the top drive drilling rig in contact with liquid level within drill string which is generally located wellbore, second trip tank connected to and drawworks position indicator. The sensors detect signals reflected from interfaces allowing calculation injected volumes into wellbore volume changes string. allows tubular removed over time. Comparison or totaling calculated early unwanted fluid fluxes between an formation.
