发明名称 Método para determinar uma quantidade de escoamento lento e viscoso para uma ferramenta em um cabo posicionado em um poço em um campo de petróleo, ferramenta de diagnóstico para posicionamento em um poço em campo de petróleo, e conjunto de diagnóstico para estabelecer um perfil de um poço em um campo de petróleo
摘要 <p>A method for determining an amount of creep for a tool on a cable and positioned in a well at an oilfield. The method includes moving a winch at a surface of the oilfield to effect movement of the tool below the surface in the well. The winch may then be stopped with the tool still in the well, but frequently the tool will continue to move, or "creep", for some time after the winch is stopped. After the winch is stopped, data may be recorded indicative of movement of the tool. This data may then be used for the determining of the amount of creep.</p>
