操作员在套管井环境中建造了许多需要对多个区域进行主动防砂的井，可选择区域选择性，并可能通过井干预隔离水淹区。这些井中最常用的油管是 3 英寸油管，当在标准的 9 英寸多区域单程 (MZST) 砾石充填系统中使用时，这对选择性提出了挑战。

Optimized Multizone Single-Trip Gravel-Pack System Deployed in Brownfield

This paper describes an optimized multizone single-trip gravel-pack system developed and implemented successfully in Brunei.

The operator constructs many wells that require active sand control for multiple zones in cased-hole environments with the option for zonal selectivity and the possibility of watered-out zones to be isolated through well intervention. The most frequently used tubing in these wells is 3½-in. tubing, which poses a selectivity challenge when used in the standard 9⅝-in. multizone single-trip (MZST) gravel-pack system.
