Well-SunModel 4U -Portable Data Acquisition System for Cased-Hole Well Logging

SHARE
The Portable Data Acquisition System (DAS) 4U by Well-Sun is an integrated system designed for cased-hole well logging applications. Utilizing a mono-conductor cable, it excels in the collection and processing of logging data, which it can display in graph or curve formats. This system facilitates online interpretation of various logged products. It features a two-way transmission function and uses USB for enhanced transmission rates. The modular design divides each functional module for better expandability, and a customized bus board with added buffer and network resistance ensures higher reliability. The system is driven by Digital Signal Processing (DSP) and Complex Programmable Logic Device (CPLD) technologies. It supports multiple logging tools and is compatible with DDL III WSCbus and the 3504 protocol. Additionally, it outputs data in multiple formats, including LAS, DLIS, and WS.
