DISTANCE SYSTEM BE USED WHEN COMPLETING WITH BRINE DRILLING WELLS.

摘要

Specification discloses a process for completing a wellbore into a subterranean reservoir. In completing the wellbore, a completion fluid is pumped into the wellbore casing to displace the mud contained therein, the improvement comprising pumping a spacer system into the wellbore casing before pumping the completion fluid into the wellbore. The spacer system comprises a spacer fluid having a viscosity sufficiently high such that the spacer fluid exists in either laminar or plug flow at normal circulation rates.
