Abstract

La presente invención se refiere a mejoras en método para el registro de perfil de pozos, produciendo un perfil de los medios que rodean un pozo de sondeo que atraviesa una formación terrestre, que comprende los pasos de: mover un instrumento de perfil de pozo en una dirección a lo largo del eje de los pozos de sondeo; acelerar partículas cargadas de altos niveles de energía en un número de cavidades individuales que contienen un campo de aceleración; bombardear un blanco con las partículas aceleradas para emitir radiación nuclear que penetre los medios circundantes; detectar la radiación nuclear que regresa al pozo de sondeo como un resultado de la interacción de la radiación emitida y los medios circundantes, y grabar representaciones de la radiación detectada; caracterizadas por: controlar la aceleración de las partículas en respuesta a variaciones de por lo menos una condición de las cavidades.The present invention relates to improvements in the method for recording well profiles, producing a profile of the means surrounding a borehole that crosses a land formation, comprising the steps of: moving a well profile instrument in a direction along the axis of boreholes; accelerate charged particles of high energy levels in a number of individual cavities containing an acceleration field; bombarding a target with the accelerated particles to emit nuclear radiation penetrating the surrounding media; detecting nuclear radiation returning to the borehole as a result of the interaction of the emitted radiation and the surrounding media, and recording representations of the detected radiation; characterized by: controlling the acceleration of the particles in response to variations of at least one condition of the cavities.
