Abstract
Procedimiento de exploración sísmica para la obtención de un registro de perfil sísmico vertical de un pozo de perforación que atraviesa formaciones terrestres, que comprende las operaciones que consisten en: emitir ondas acústicas a partir de una fuente sensiblemente fija; detectar las ondas acústicas sudo-periódicas que llegan a un punto de detección dispuesto en el pozo a una primera profundidad, y originar una señal de detección; registrar, para la citada primera profundidad, una primera forma de onda, constituida por las variaciones de la señal de detección en el curso del tiempo; controlar el desplazamiento del punto de detección en el pozo de la citada primera profundidad a una segunda profundidad y reiterar, en esta segunda profundidad, las operaciones procedentes para obtener, en esta segunda profundidad, una segunda forma de onda, caracterizado porque comprende una operación preliminar que consiste en medir la velocidad de propagación de las ondas acústicas en las formaciones en la proximidad del pozo, en zonas de profundidades diferentes contiguas a lo largo del pozo, comprendiendo la citada operación de control del desplazamiento, la determinación del citado desplazamiento en función de la citada velocidad de propagación medida, porque comprende una operación de combinación de las primera y segunda formas de ondas en función del citado desplazamiento y de la velocidad de propagación medida entre las citadas profundidades primera y segunda, y porque comprende una operación de registro de la forma de onda resultante de la citada combinación, sobre la que aparecen, de modo reforzado, las variaciones de señal que corresponden a las ondas que han sufrido una reflexión.Seismic exploration procedure for obtaining a vertical seismic profile record of a drilling well that crosses terrestrial formations, comprising the operations that consist of: emitting acoustic waves from a substantially fixed source; detecting the sudo-periodic acoustic waves that arrive at a detection point arranged in the well at a first depth, and originating a detection signal; recording, for said first depth, a first waveform, constituted by the variations of the detection signal over time; controlling the movement of the detection point in the well from said first depth to a second depth and repeating, at this second depth, the operations proceeding to obtain, at this second depth, a second waveform, characterized in that it comprises a preliminary operation which consists of measuring the speed of propagation of the acoustic waves in the formations in the vicinity of the well, in zones of different depths contiguous along the well, comprising the aforementioned displacement control operation, the determination of said displacement as a function of said measured propagation speed, because it comprises a combination operation of the first and second waveforms as a function of said displacement and of the propagation speed measured between said first and second depths, and because it comprises a recording operation of the waveform resulting from the aforementioned combination, on which ap The signal variations that correspond to the waves that have undergone a reflection appear, in a reinforced way.
