Abstract
1. Способ определения уровня жидкого топлива в подземном хранилище, заключающийся в размещении внутри хранилища рабочей колонны, башмак которой контактирует с продуктом, плавающим над более плотным солевым раствором хранилища, а устье расположено над поверхностью земли, излучении акустического импульса с помощью излучателя вдоль колонны и приеме в устье колонны отраженного от поверхности раздела газ - продукт импульса акустическим приемником с последующим измерением времени прохода импульсом расстояния от излучателя до приемника, по которому определяют уровень жидкого топлива в подземном хранилище, отличающийся тем, что заполняют до устья продуктом хранилища рабочую колонну, измеряют время tпрохода импульсом расстояния hот излучателя до границы продукт - солевой раствор и обратно до приемника, время t+ tпрохода импульсом расстояния hот излучателя до дна хранилища и обратно до приемника, время t+ tпрохода импульсом соответственно расстояния от излучателя до границы раздела продукт - солевой раствор и двойного расстояния от границы продукт - солевой раствор до границы газ - продукт и обратно от границы продукт - солевой раствор к приемнику, а уровень hпродукта и уровень hсолевого раствора, а также глубину hхранилища напротив башмака рабочей колонны определяют из математических соотношенийгде c, c- скорость звука соответственно в продукте и солевом растворе.2. Способ по п. 1, отличающийся тем, что рабочую колонну заполняют до устья продуктом хранилища путем подачи в подземное хранилище газа под давлением.3. Способ по пп.1 и 2, отличающийся тем, что акустический импульс излучают в рабочую колонну не позднее чем чер�1. A method for determining the level of liquid fuel in an underground storage, which consists in placing a working column inside the storage, the shoe of which is in contact with the product floating above the denser saline solution of the storage, and the mouth is located above the ground, emitting an acoustic pulse with the help of a transmitter along the column and receiving at the column mouth of the gas reflected from the interface, the product of a pulse by an acoustic receiver, followed by measuring the time of passage of the pulse from the emitter to the receiver, according to which the level of liquid fuel in the underground storage is determined, characterized in that the working column is filled to the mouth of the storage product, the transit time is measured the pulse of the distance h from the emitter to the product - saline solution and back to the receiver, the time t + t of the pulse passage of the distance h from the emitter to the bottom of the storage and back to the receiver, the time t + t of the pulse passage, respectively, the distance from the emitter to the product - salt interface solution and double the distance from the product - brine interface to the gas - product interface and back from the product - saline interface to the receiver, and the hproduct level and the h salt solution level, as well as the depth h of the storage opposite the working column shoe, are determined from mathematical relations where c, c - the speed of sound, respectively, in the product and in the saline solution. 2. The method according to claim 1, characterized in that the working column is filled to the mouth with the storage product by supplying gas under pressure to the underground storage. The method according to claims 1 and 2, characterized in that the acoustic pulse is emitted into the working column no later than black
