Full-Bore Spinner Mechanical Tool
Provides variable-bore size access for fluid velocity measurement
Applications
Production logging flow and injection profiling
Features and Benefits
- Combinable with flow and temperature electronics (FLTE) tool
- Centerline flow measurement at bottom of tool string
- Collapsible assembly for compatibility with minimum wellbore restriction
Tool Description
The Weatherford full-bore spinner mechanical (FBSM) tool combines flowmeter sensor electronics with a fast-response temperature tool or with the 1 11/16-in. combined capacitance, flow and temperature (CFT) tool.
The flowmeter closes while passing through the completion tubing and other restrictions and opens in the casing or liner, enabling use of optimum-diameter impellers that occupy a large cross-sectional area. The FBSM can be used in all casing sizes from 4 1/2 to 9 5/8 in.
The tool is fitted with an Elgiloy® spring, tungsten carbide rollers, and with replaceable bushes.
