Title
(EN) CONSTRUCTION AND OPERATION OF AN OILFIELD MOLTEN SALT BATTERY
(ES) CONSTRUCCION Y OPERACION DE UNA BATERIA DE SAL FUNDIDA EN CAMPO PETROLERO
Abstract
(EN)
Construction and operation of an oilfield molten salt battery. A battery includes an outer case, an elongated mandrel positioned within the outer case, and the mandrel being an electrical component of the battery. Another battery includes an electrical pickup, and a polymer insulator providing insulation between the outer case and the pickup. A method of charging a battery for use in a subterranean well includes the steps of:providing the battery including an electrolyte, and anode and cathode electrodes, the electrolyte being a molten salt comprising lithium salt, and at least one of the electrodes comprising lithium atoms;positioning the battery within a wellbore;and then charging the battery. Another method includes the steps of:heating the lithium ion molten salt battery;then charging the battery;and then positioning the battery within a wellbore.

La invención concierne con una construcción y operación de una batería de sal fundida para campo petrolero. Una batería incluye un recubrimiento exterior, un mandril alargado colocado dentro del recubrimiento exterior, y el mandril es un componente eléctrico de la batería. Otra batería incluye un captador eléctrico, y un aislante polimérico que provee aislamiento entre el recubrimiento exterior y el captador. Un método de carga de una batería para uso en un pozo subterráneo incluye los pasos de:proveer la batería que incluye un electrolito, y eléctrodos deánodo y cátodo, el electrolito es una sal fundida que comprende sal de litio, y por lo menos uno de los eléctrodos que comprendeátomos de litio;colocar la batería dentro de una perforación de pozo;y luego cargar la batería. Otro método incluye los pasos de:calentar la batería de sal fundida de ión de litio;luego cargar la batería;y luego colocar la batería dentro de una perforación de pozo.
