DEFLECTOR ASSEMBLY FOR A LATERAL WELLBORE |
摘要 |
Disclosed is a multi-deflector assembly for guiding a bullnose assembly into a selected borehole within a wellbore. One deflector assembly includes an upper deflector arranged within a main bore of a wellbore and defining first and second channels that extend longitudinally through the upper deflector, wherein the second channel exhibits a width greater than that of the first channel, and a lower deflector arranged within the main bore and spaced from the upper deflector by a predetermined distance, the lower deflector defining a first conduit that communicates with a lower portion of the main bore and a second conduit that communicates with a lateral bore, wherein the upper and lower deflectors are configured to direct a bullnose assembly into one of the lateral bore and the lower portion of the main bore based on a length of a bullnose tip of the bullnose assembly as compared to the predetermined distance. |
