Abstract
Способ определения гидравлической податливости ствола скважины во время процесса бурения с управляемым давлением. Производятся измерения давления бурильного текучей среды, циркулирующего в стволе скважины во время процесса на верху кольцевого пространства, расхода qтекучей среды в ствол скважины и расхода qтекучей среды из ствола скважины. Результаты измерений этих трех величин используются для определения разности расходов и дискретной производной давления по времени (P-PΔ)/Δt, где t - время, a Δt - временной интервал. Разности расходов и производных по времени затем обрабатываются путем применения фильтра низких частот для определения гидравлической податливости ствола скважины.
