PRODUCTION LOGGING SPINNER CLEANING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18087593 titled 'PRODUCTION LOGGING SPINNER CLEANING
The abstract describes a production logging tool that includes a housing connected to a well string in a wellbore, a flowmeter assembly with a spinner exposed to fluid in the wellbore, and a cleaning assembly with a fluid nozzle directed at the spinner. The spinner rotates about its central axis, and the fluid nozzle directs cleaning fluid at the spinner. The cleaning assembly includes a fluid pump to drive the flow of cleaning fluid and a controllable fluid valve to regulate the flow of cleaning fluid to the nozzle.
- The production logging tool is designed to be connected to a well string in a wellbore.
- The flowmeter assembly includes a spinner that is exposed to fluid in the wellbore.
- The cleaning assembly is connected to the housing and includes a fluid nozzle directed at the spinner.
- The spinner rotates about its central axis, while the fluid nozzle directs a flow of cleaning fluid at the spinner.
- The cleaning assembly includes a fluid pump and a controllable fluid valve to control the flow of cleaning fluid to the nozzle.
Potential Applications: - Monitoring fluid flow in wellbores - Cleaning and maintaining spinners in flowmeter assemblies
Problems Solved: - Ensuring accurate measurement of fluid flow in wellbores - Preventing buildup and blockages on spinners in flowmeter assemblies
Benefits: - Improved accuracy in production logging - Reduced maintenance and downtime for flowmeter assemblies
Commercial Applications: - Oil and gas industry for monitoring well production - Well logging and maintenance companies
Prior Art: - Prior art related to production logging tools and flowmeter assemblies in the oil and gas industry.
Frequently Updated Research: - Ongoing research on improving flow measurement accuracy in wellbores.
Questions about Production Logging Tool: 1. How does the cleaning assembly in the production logging tool help maintain accurate measurements? 2. What are the potential challenges in implementing this technology in different wellbore conditions?
Original Abstract Submitted
A production logging tool includes a housing having a first end configured to connect to a well string disposed in a wellbore, a flowmeter assembly supported by the housing and including a spinner exposed to fluid in the wellbore, and a cleaning assembly connected to the housing and including a fluid nozzle directed at the spinner. The spinner rotates about a central rotational axis of the spinner, and the fluid nozzle direct a flow of cleaning fluid at the spinner. The cleaning assembly can include a fluid pump fluidly connected to the fluid nozzle to drive the flow of cleaning fluid to the fluid nozzle, and a controllable fluid valve between the fluid pump and the fluid nozzle to control the flow of cleaning fluid to the fluid nozzle.
