Цель изобретени - упрощение процесса измерени .The purpose of the invention is to simplify the measurement process.
Указанна цель достигаетс тем, что измер ют прирост гидродинамического давлени за врем спуска колонны труб на заданнуюThis goal is achieved by measuring the increase in hydrodynamic pressure during the descent of a pipe string to a predetermined
глубину, по величине которого определ ют скорость прироста температуры.depth, which determines the rate of temperature increase.
Способ измерени осуществл етс следующим образом.The measurement method is as follows.
Дл регистрации градиента гидродинамического давлени потока бурового раствора в кольцевом пространстве скважины при выполнении спуско-подъемных операций использованы глубинный манометр типа МГИ.To register the gradient of the hydrodynamic pressure of the flow of drilling fluid in the annular space of the well, when performing tripping operations, a depth gauge of the MGI type was used.
Перемещение колонны труб приводит кMoving the pipe string results in
соответствующему передвижению бурового раствора в кольцевом пространстве скважины вследствие вь1теснени его колонной при спуске или заполнении объема освобождаемого колонной при подъеме, что вл етс причиной возникновенн гидродинамического давлени .the corresponding movement of the drilling fluid in the annular space of the well due to its oppression by the column during the descent or filling of the volume released by the column during the ascent, which is the cause of the hydrodynamic pressure.
В процессе экспериментальных исследований установлено, что диссипаци кинетической энергии бурового раствора и работы сил трени привод т к разогреву бурового раствора, причем скбрость прироста температуры зависит от градиента гидроди1имического давлени .In the course of experimental studies, it was found that dissipation of the kinetic energy of the drilling fluid and the work of the friction forces leads to heating of the drilling mud, and the temperature increase depends on the hydrodynamic pressure gradient.
На чертеже приведена коррел ционна зависимость градиента гидродинамического давлени потока бурового раствора в скважине от скорости прироста температуры.The drawing shows the correlation dependence of the gradient of the hydrodynamic pressure of the mud flow in the well on the rate of temperature increase.
Таким образом, по измеренному глубинным манометром приросту гидродинамического давлени за врем спуска колонны труб на заданную глубину определ ют скорость прироста температуры.Thus, according to the increase in hydrodynamic pressure measured by the depth gauge during the descent of the tubing to a predetermined depth, the rate of temperature increase is determined.
Использование глубинного манометра дл из мерени прироста температуры имеет преимущества по сравнению с применением малоинериионных электротермометров.The use of a depth gauge for measuring temperature gains has advantages over the use of low-ion electric thermometers.
Применение глубинного манометра дл измерени скорости прироста температуры бурового раствора в скважине при выполнении спускоподъемных операций обеспечит осуществление своевременного контрол и регулировани температурных изменений в скважине дл предотвращени ослрженний в процессе ее проводки.The use of a deep gauge to measure the rate of increase in the temperature of the drilling fluid in the borehole during tripping will ensure timely monitoring and control of temperature changes in the borehole to prevent oscillation during its installation.
Кроме того, возможность одновременного замера гидродинамического давлени и прироста температуры исключает проведение дополнительных специальных измерительных работ с использованием глубинных термометров.In addition, the possibility of simultaneous measurement of hydrodynamic pressure and temperature increase precludes the carrying out of additional special measurement work using deep-sea thermometers.
