- the present invention relates to a downhole completion device configured to be mounted as part of a well tubular metal structure. Furthermore, the invention relates to a downhole completion system.
- the senor When having electrical components downhole, such as a pressure or temperature sensor, the sensor is subjected to both high temperature and high pressure.
- the sensor is often comprised in a housing, but when the temperature in the well increases, the pressure in the housing also increases, which jeopardises the functionality of the sensor.
- a downhole completion device configured to be mounted as part of a well tubular metal structure, comprising:
- the electrical component is protected from any temperature and pressure changes that naturally occur downhole in a well during production, fracturing, aciding, gas lifting or other activities taking place downhole during the service life of a well.
- the second housing section may be made of a non-metallic material.
- the electrical component may be a sensor.
- the electrical component may be a piezoelectric element, a strain gauge, a coil or an anemometer.
- the second thickness may be less than 50% of the first thickness.
- the second thickness may be less than 33% of the first thickness, preferably less than 25%.
- the housing may have an outer face and the outer face may be provided with a thread.
- liquid may be silicone, grease or any liquid suitable for electrical components.
- the housing may have a third housing section having a third thickness, the third thickness being smaller than the first thickness.
- the second housing section may have a projected state in which the liquid has a second volume being larger than the first volume, and a retracted state in which the liquid has a third volume being smaller than the first volume.
- the downhole completion device may further comprise a communication unit connected with the electrical component.
- the downhole completion device may further comprise a storage unit connected with the electrical component.
- the downhole completion device may further comprise a power supply arranged in the space.

- the well tubular metal structure may comprise one or more annular barriers, each annular barrier comprising:
- Fig. 1 shows a downhole completion device 1 configured to be mounted as part of a well tubular metal structure 2 in a borehole 30.
- the downhole completion device 1 comprises a metal housing 3 enclosing a closed space 4 and an electrical component 5, such as a coil 32, arranged in the space inside the metal housing.
- the metal housing 3 is filled with a liquid 41 having a first volume V 1 of 1 bar at 20°C.
- the metal housing 3 has a first housing section 6 and second housing section 7.
- the first housing section 6 has a first thickness t 1 and the second housing section 7 has a second thickness t 2 , and the second thickness is smaller than the first thickness so that the second housing section is more flexible than the first housing section.
- the electrical component is hereby protected from any temperature and pressure changes that naturally occur downhole in a well during production, fracturing, aciding, gas lifting or other activities taking place downhole during the service life of a well.
- the liquid inside the downhole completion device 1 surrounds the electrical component and thereby protects the electronics from these bumps during installation of the well tubular metal structure since the liquid fills out the space and has a substantially dampening effect when such bumps and shakings occur.
- the second housing section 7 may be made of metal or a non-metallic material.
- the second housing section 7 is in Figs. 1-3 a separate part fastened to the first housing section 6, and in Fig. 4 , the second housing section 7 is made as a thinner part of the metal housing 3 and not as a separate part.
- the second thickness is less than 50% of the first thickness, and the second housing section 7 is made of the same material as the first housing section 6.
- the downhole completion device 1 extends through a wall of the well tubular metal structure 2 and partly projects from the outer face 28 of the well tubular metal structure 2.
- the downhole completion device 1 has a longitudinal extension 15 being perpendicular to a longitudinal axis 12 and extends radially from the longitudinal axis.
- the electrical component 5 is a sensor, such as an anemometer having a hot wire 17, extending from the metal housing 3 into the borehole 30 and is thus in connection with the well fluid.
- the metal housing 3 has an outer face 8, and the outer face is provided with a thread 9.
