Abstract
Orientation system for downhole device (10), wherein the orientation system comprises an outer magnetic orientation lock assembly (460) arranged in connection with or integrated in the downhole device (10) and an orientation instrument assembly (400) for insertion into the outer magnetic orientation lock assembly (460), and wherein the orientation instrument assembly (400) comprises a sensor assembly (420) rotatably arranged in the orientation instrument assembly (400) and arranged for aligning or orienting in relation to the outer magnetic orientation lock assembly (460).
Claims9
Orientation system for downhole device, comprising
- an outer magnetic orientation lock assembly arranged in connection with or integrated in the downhole device, and
- a retrievable orientation instrument assembly for insertion into the outer magnetic orientation lock assembly,
- wherein the retrievable orientation instrument assembly comprises a sensor assembly and a magnetic instrument alignment assembly,
- wherein the sensor assembly comprises a sensor housing and at least one metering element or sensor housed therein,
- wherein the sensor assembly and magnetic instrument orientation assembly are rotatably arranged in the retrievable orientation instrument assembly,
- wherein the magnetic instrument alignment assembly is axially aligned with and spaced apart from the sensor assembly and fixed thereto so that they rotate as one unit, and
- wherein the magnetic instrument alignment assembly is aligning or orienting the sensor assembly according to the magnetic field direction of the outer magnetic orientation lock assembly and locking the position of the sensor assembly in this position for measuring the orientation of the downhole device.
