ActivePetroleum and natural gas industries - Equipment for well cementing - Part 2: Centralizer placement and stop-collar testing
石油天然气工业 固井设备 第2部分：扶正器的放置和止动环测试
Application Summary AI generated
This standard specifies the requirements for the placement of centralizers and the performance testing of stop-collars used in well cementing operations within the petroleum and natural gas industries. It is applied during the design and execution of cementing jobs to ensure proper casing centralization and secure stop-collar functionality, which are critical for achieving zonal isolation and preventing gas migration. The standard is used by drilling and completion engineers, as well as equipment manufacturers, to validate that centralizer placement and stop-collar testing meet industry specifications for downhole conditions.
