SK-WFS Well Factory Logging Unit

Overview
SK-WFS Well Factory Logging Instrument is a new generation of oil exploration and development equipment developed to meet the needs of shale gas drilling site logging. It is based on the company's accumulated professional technology over the years, relying on the company's advantages in scientific and technological talents and Shanghai's strong industrial foundation. The instrument is in the leading position in China in terms of overall design and manufacturing technology, and has reached the international advanced level.

SK-WFS well factory logging instrument adopts a set of logging instruments to realize simultaneous logging of two or more wells on site. It is not only equipped with conventional fast chromatograph and CAN bus data acquisition system, but also equipped with wireless sensors and wellhead chromatography system, which can fully meet the logging tasks in the well factory operation mode.


Highlights
1. The logging instrument room provides a work area for logging personnel, making the working environment more comfortable.
2. The chromatograph is installed at the wellhead to shorten pipeline delay and obtain gas test results faster.
3. The wireless sensor system reduces on-site wiring and meets the requirements for rapid installation of multiple wells.
4. Reduce on-site logging personnel and reduce logging costs.
5. Dual servers at the well site and base meet remote logging requirements.
