Abstract

Un operador de un equipo de servicios para pozos puede recuperar y monitorear una visualizacion de datos de posicion de aparejo movil durante la insercion y remocion de tuberías y varillas. El operador ingresa en el sistema un rango de altura máximo y mínimo dentro del cual él desea que opere el aparejo movil. Al operador se le proporcionan datos en tiempo real sobre un visualizador gráfico relativos a los datos de posicion mínima y máxima ingresados por el operador para asistirlo en la evaluacion de la posicion del aparejo movil antes de producirse una coronacion o un hundimiento. Además se proporcionan métodos para evaluar las actividades realizadas en un equipo de servicios en base a la evaluacion de los datos de posicion del aparejo movil para supervisar una operacion de equipo de servicios desde una posicion remota. Además, la tecnología permite al operador o supervisor determinar la velocidad del aparejo movil durante las operaciones evaluando datos de velocidad de un codificador provistos por un gráfico de velocidad de codificador.
