METHOD FOR PREDICTING STABILITY OF WELL SHAFT IN SALT MASSIVE

摘要

FIELD: geophysics.;SUBSTANCE: method includes estimation of side mountain pressure of salt massive on basis of speed of longitudinal and transverse waves of acoustic logging cable with lowered hydrostatic pressure, appropriate for conditions of behind-column space. Potentially dangerous ranges , concerning deformation of casing string, are determined by surpassing of hydrostatic pressure by side mountain pressure.;EFFECT: higher reliability and precision.;1 dwg
