Summary: | The purpose of the present invention is to provide a process for experimentally determining reliable dynamic viscosities in heavy crude oil at a constant temperature (room temperature up to 463 K) and pressures of from about 68.9 MPA to about atmospheric pressure, including the dynamic viscosity in the bubble point pressure and under the same, based on a simple, reliable and accurate device. The device used in the present invention is based on an electromagnetic concept which only uses a mobile element (piston) through a fluid at a constant force. The time required by the piston to travel a fix distance is related in an exact manner to the dynamic viscosity of the fluid contained in a measurement chamber. When the fluid contained in the measurement chamber is more viscous, the displacement of the piston would be slower.
El objeto de la presente invención es proporcionar un proceso para determinar experimentalmente viscosidades dinámicas confiables de crudo vivo pesado a una temperatura constante (temperatura ambiente hasta 463 K) y presiones desde 68.9 MPa hasta la presión atmosférica, incluyendo la viscosidad dinámica en el punto de la presión de burbuja y por debajo de ésta, basado en un aparato simple, confiable y preciso. El aparato usado en la presente invención está basado en un concepto electromagnético que usa solamente un elemento móvil (pistón) a través de un fluido a una fuerza constante. El tiempo requerido para que el pistón recorra una distancia fija es relacionado de manera exacta a la viscosidad dinámica del fluido contenido en una cámara de medición. Cuando el fluido contenido en el interior de la cámara de medición sea más viscoso, el desplazamiento del pistón será más lento. |
