Abstract
CONSISTE EN EL AUMENTO DE LA EFICIENCIA DEL METODO DE TRATAMIENTO DE LA ZONA MATRIZ PRODUCTORA POR MEDIO DE LA REDUCCION DEL ARRASTRE DE PARTICULAS DE MATERIAL CONTAMINANTE SEGUN LAS CONDICIONES GEOLOGICAS-FISICAS DE LAS CATEGORIAS DE LOS POZOS, QUE INCLUYE LA ESTIMULACION VIBROONDULATORIA Y EL CAMBIO DE PRESION, CARACTERIZADO PORQUE LA PRESION DE LA ZONA MATRIZ PRODUCTORA SE REDUCE HASTA QUE SEA MENOR QUE LA PRESION DE CAPA Y LA ESTIMULACION VIBROONDULATORIA SE REALIZA MIENTRAS AUMENTA LA PRESION (LIMITADO POR LA PRESION DEL FRACTURAMIENTO HIDRAULICO DE CAPA); LA REDUCCION DE PRESION EN EL FRENTE DEL POZO SE HACE CON LA BOMBA A CHORRO, Y LA ESTIMULACION VIBROONDULATORIA CON UNA FRECUENCIA DE 1 Hz A 700 Hz SE PRODUCE CON EL GENERADOR HIDRODINAMICO QUE LOGRA EL DESPLAZAMIENTO VIBRATORIO DEL COLECTOR DE PETROLEO EN MAS DE 0,1 VECES EL VALOR DEL DIAMETRO PROMEDIO DE LOS CANALES DE LOS POROS Y LA ACELERACION VIBRATORIA EN MAS DE 0,1 VECES EL VALOR DE LA ACELERACION DE CAIDA LIBRE, LA ESTIMULACION SE REALIZA HASTA LA ESTABILIZACION DE BOMBEO DEL FLUIDO DE CAPA, Y CUANDO ESTA SE REDUCE SE REPITE EL CICLO DE LA ESTIMULACION CON LAS OSCILACIONES ELASTICAS. SE USA PARA MEJORAR LA LIMPIEZA DE LOS POZOS DE YACIMIENTOS DE PETROLEO EN CONDICIONES COMPLICADAS DE TRATAMIENTO Y, PARA LOS POZOS DIRIGIDOS Y DIRIGIDOS-HORIZONTALESIT CONSISTS IN THE INCREASE OF THE EFFICIENCY OF THE METHOD OF TREATMENT OF THE PRODUCTION MATRIX ZONE THROUGH THE REDUCTION OF THE TRAILING OF PARTICLES OF CONTAMINATING MATERIAL ACCORDING TO THE GEOLOGICAL-PHYSICAL CONDITIONS OF THE CATEGORIES OF THE WELLS AND THE VIB STIMULATION PRESSURE, CHARACTERIZED BECAUSE THE PRESSURE OF THE PRODUCING MATRIX ZONE IS REDUCED UNTIL IT IS LESS THAN THE LAYER PRESSURE AND THE VIBROONDULATORY STIMULATION IS PERFORMED WHILE THE PRESSURE IS INCREASED (LIMITED BY THE PRESSURE OF THE HYDRAULIC LAYER FRACTURING); THE PRESSURE REDUCTION IN FRONT OF THE WELL IS MADE WITH THE JET PUMP, AND THE VIBROONDULATORY STIMULATION WITH A FREQUENCY OF 1 Hz TO 700 Hz IS PRODUCED WITH THE HYDRODYNAMIC GENERATOR THAT ACHIEVES THE VIBRATORY DISPLACEMENT OF THE OIL COLLECTOR BY MORE THAN 0, 1 TIMES THE VALUE OF THE AVERAGE DIAMETER OF THE PORE CHANNELS AND THE VIBRATORY ACCELERATION IN MORE THAN 0.1 TIMES THE VALUE OF THE FREE FALL ACCELERATION, THE STIMULATION IS PERFORMED UNTIL THE PUMP STABILIZATION OF THE LAYER FLUID, AND WHEN THIS REDUCES THE CYCLE OF STIMULATION WITH ELASTIC OSCILLATIONS. IT IS USED TO IMPROVE THE CLEANLINESS OF OIL WELLS IN COMPLICATED TREATMENT CONDITIONS AND, FOR DIRECTED AND DIRECTED-HORIZONTAL WELLS
