Abstract
The utility model relates to a horizontal well steam injection well head sealing device comprises sealed lid, graphite sealing ring, seal gasket, sealed main part, and sealed main part upper end has sealed lid with threaded connection, is equipped with graphite sealing ring and seal gasket between the two, and sealed lid compresses tightly graphite sealing ring and seal gasket, makes the cable extraction department that passes through from the centre hole realize reliably sealing. The utility model discloses rational in infrastructure, the installation is dismantled portably, and reliable operation utilizes it to guarantee that horizontal steam injection well test cable extraction position is long-term sealed under the high temperature high pressure condition to guarantee going on smoothly of horizontal steam injection well dynamic monitoring.
Description
Technical field:
The utility model relates to a kind of well mouth sealing device that the viscous crude heat extraction by steam injection is annotated the dynamic monitoring of carbonated drink horizontal well that is used for.
Background technology:
In viscous crude heat extraction by steam injection process, need carry out dynamic monitoring to annotating the carbonated drink horizontal well.At present, horizontal well notes vapour well head test cable sealing device is one of technological difficulties of annotating carbonated drink horizontal well long term monitoring system.Owing to is high temperature and high pressure steam fully in the steam injection string,, therefore need the monitoring system test cable is carried out intact sealing to cable by the down-hole when well head is drawn if poorly sealedly will cause serious harm.High temperature well head sealing in the past adopts poly-polytetrafluoroethylsealed sealed packing that cable is carried out the short-term sealing usually, under long term high temperature, can sex change lose effect, yet the monitoring of horizontal steam injection well is generally all more than 1 month, and existing well head Sealing Technology can't guarantee long-term sealing effectiveness.
The utility model content:
The purpose of this utility model is to provide a kind of test cable that can guarantee under hot conditions effectively to seal drawing the well head director phase, guarantees that the horizontal steam injection well long term monitoring horizontal well that carries out working properly annotates the vapour well mouth sealing device.
The utility model purpose is to realize like this.This kind well mouth sealing device is made up of seal cover, graphite-seal ring, gasket seal, sealed body, its structure assembled relation is as follows: the sealed body upper end is with the seal cover that has been threaded, graphite-seal ring and gasket seal are housed between the two, seal cover compresses graphite-seal ring and gasket seal, the cable that passes through from mesopore is drawn realize positiver sealing.During use, this device sealed body lower end is connected to notes vapour well well head by the high temperature slips, monitoring is connected with data collecting system by the sealing device with the test pillar, and the seal cover upper end connects by slips, fixedly sets upright.
The utility model is rational in infrastructure, and reliable operation utilizes it can guarantee horizontal steam injection well test cable extraction location long term seal under high-temperature and high-pressure conditions, thereby guarantees carrying out smoothly of horizontal steam injection well dynamic monitoring.This device is convenient to dismounting when monitoring system is keeped in repair, can finish maintenance under the situation of not damaging inside cable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.Fig. 2, Fig. 3, Fig. 4 are respectively sealed body 4, gasket seal 3, seal cover 1 structural representation.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is made up of seal cover 1, graphite-seal ring 2, gasket seal 3, sealed body 4.Wherein, seal cover 1 lower end periphery has to be connected with sealed body 4 uses screw thread, and mesopore bottom inner headed face is provided with installs graphite-seal ring 2 and gasket seal 3 is used step, and graphite-seal ring 2, gasket seal 3 are the annular seal circle.Each parts all has mesopore so that cable passes through.
Claims (1)
