Description
Изобретение относится к области ^исследования скважин и может быть Использовано для определения давления и температуры в скважинах.The invention relates to the field of well testing and can be used to determine the pressure and temperature in wells.
Цель изобретения -, повышение надежности работы устройства в ус^· ловиях высоких температур.The purpose of the invention is to improve the reliability of the device in the conditions of high temperatures.
На фиг. 1 изображено глубинное регистрирующее устройство», на фиг. 2 -диаграмма записи.FIG. 1 shows a deep recording device ", FIG. 2 -diagram recording.
Глубинное регистрирующее устройство содержит корпус 1, манометрический блок, включающий штуцер 2, фильтр.3, цилиндрическую-пружину 4 с поршнем 5, термометрический блок, включающий фильтр 6, биметаллическую пружину 7 со штоком 8, и механизм регистрации, включающий барабан 9 и перо 10. В корпусе · 1 выполнены окна Ί1 и 12 для поступления пластовой жидкости.The depth recording device comprises a housing 1, a manometric unit including a fitting 2, a filter 3, a cylindrical spring 4 with a piston 5, a thermometric unit including a filter 6, a bimetallic spring 7 with a rod 8, and a recording mechanism including a drum 9 and a feather 10 In the case · 1 there are windows выполнены1 and 12 for inlet of formation fluid.
Поршень 5 манометрического блока соединен с барабаном 9, а шток 8 термометрического блока связанThe piston 5 of the gauge unit is connected to the drum 9, and the rod 8 of the thermometric unit is connected
с пером. with a feather.
. Глубинное регистрирующее устройство работает следующим образом.. Deep recording device operates as follows.
При спуске устройства- в скважину давление окружающей среды передается через штуцер 2 и фильтр 3 поршню 5,/ который перемещает барабан 9 по оси устройства. Одновременно под воздействием температурыWhen the device is lowered into the well, the ambient pressure is transmitted through fitting 2 and filter 3 to the piston 5, / which moves the drum 9 along the axis of the device. Simultaneously under the influence of temperature
окрудающей среды биметаллическая пружина 7 со штоком 8 сообщает перу 10 круговое движение. Перемещение барабана 9 и пера 10 обеспечивает запись диаграммы в координатах Е (давление) и ί (темпетарура). При ' . опускания устройства в скважину одновременно увеличиваются давление и температура, что способствует одновременному перемещению пера по горизонтали и барабана по вертикали. При этом. на диаграмме получается наклонная линия. При остановке на заданной глубине действие давления прекращается раньше и бара-, бан не перемещается.environment bimetallic spring 7 with a rod 8 tells the pen 10 a circular motion. The movement of the drum 9 and the pen 10 provides the recording of the chart in the coordinates E (pressure) and ί (temperarura). With '. lowering the device into the well simultaneously increase the pressure and temperature, which contributes to the simultaneous movement of the pen horizontally and the drum vertically. Wherein. the diagram is an oblique line. When stopping at a given depth, the pressure stops earlier and the bar does not move.
Действие температуры протекает более медленно, поэтому пружина 7 про20 должает раскручиваться и перемещает перо по горизонтали. При остановке на разных глубинах получается сту-" с пенчатая запись,7на которой вертикальная проекция наклонной линии пред25 ставляет условную величину давления (Р, , Р2, Р3 и т.д.), а горизонтальная проекция наклонной и горизон• тальной - условную величину температуры (<и , ί2, и т.д.) . ·The temperature action is more slow, so the spring 7 and 20 should spin and moves the pen horizontally. When stopping at different depths, it turns out a sta- tion with a foam record, 7 on which the vertical projection of the inclined line represents 25 the conditional pressure value (Р,, Р 2 , Р 3 , etc.), and the horizontal projection of the inclined and horizontal • conditional temperature (< and ,, 2 , etc.). ·
3θ Таким образом, сочетание в одном -устройстве манометрического^ термометрического блоков обеспечивает регистрацию двух параметров без часового механизма. 3 θ Thus, a combination of a manometric thermometric block in one device ensures the registration of two parameters without a clock mechanism.
