Title: (DE) KONSTRUKTION UND FUNKTIONSWEISE EINER ÖLFELD-SCHMELZSALZBATTERIE
(EN) CONSTRUCTION AND OPERATION OF AN OILFIELD MOLTEN SALT BATTERY
(FR) FABRICATION ET FONCTIONNEMENT D'UN ACCUMULATEUR A SEL FONDU POUR UN CHAMP DE PETROLE
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.
(FR) La présente invention concerne la fabrication et le fonctionnement d'un accumulateur à sel fondu pour champ de pétrole. L'accumulateur décrit dans cette invention comprend un boîtier extérieur, un mandrin allongé placé à l'intérieur du boîtier extérieur, lequel mandrin est un élément électrique de l'accumulateur. Un autre accumulateur comprend un capteur électrique et un matériau isolant polymère assurant l'isolation entre le boîtier extérieur et le capteur. Cette invention concerne également un procédé permettant de charger un accumulateur pour l'utiliser dans un puits souterrain, lequel procédé comprend les étapes qui consistent : à utiliser l'accumulateur comprenant un électrolyte, ainsi qu'une anode et une cathode, lequel électrolyte consiste en un sel fondu comprenant du sel de lithium et au moins l'une des électrodes comprend des atomes de lithium; à placer l'accumulateur à l'intérieur du trou de forage; puis à charger l'accumulateur. Un autre procédé décrit dans cette invention comprend les étapes qui consistent à chauffer l'accumulateur à sel fondu au lithium-ion; puis à charger l'accumulateur et à placer l'accumulateur à l'intérieur du trou de forage.
