SYSTEM FOR MEASURING DOWNHOLE PARAMETERS AND A METHOD OF USING SAME

摘要

The present invention provides a system and method for measuring downhole parameters within a SAGD system. The system includes one or more downhole sensors that are positioned at least within a heel portion of a long production tubing string. Positioning the system within the long production tubing string avoids pulling the sensors to surface each time that the short production tubing string is worked over. The system comprises a ported sub that is threadably connected as part of the long production tubing string. When the tubing string is in a desired position, the ported sub is near the heel portion of the production well. The system further comprises a pumpable sleeve that carries the instrument line downhole into the ported sub. When the pumpable sleeve lands in the ported sub, the instrument line detects information regarding downhole parameters at the heel portion of the production well.

主权项

1. A system for detecting downhole parameters within a heavy oil production system, the system for detecting downhole parameters comprising:
a. a production well that is positioned proximal to the target reservoir, the production well for collecting the mobilized hydrocarbons from the target reservoir, the production well comprising:
i. a heel portion and a toe portion;ii. a short production tubing string that terminates proximal to the heel portion;iii. a long production tubing string that terminates proximal to the toe portion, the long production tubing string comprising a downhole sensor within the heel portion for detecting and transmitting information regarding downhole parameters within a space that is external to the long production tubing string.
