Ultra-High Temperature and High Pressure Slim Hole Logging System


•The ultra-high temperature and high pressure small hole (EELS) logging system includes acoustic,

electrical, radioactive and other logging instruments


•The system can be fully applied to open hole wells and cased wells, and comprehensively evaluate

the acoustic, electrical and nuclear multi-parameter formations at one time; it can make predictive

evaluations of reservoirs and conveniently evaluate the reserves of formation oil and gas reservoirs


Technical Introduction
It has the characteristics of small outer diameter, high temperature resistance, high pressure resistance, sulfur resistance and corrosion resistance. The instrument has an outer diameter of 76mm and a temperature and pressure resistance of 230"C/172MPa (or 260°C/200MPa), which can meet the extremely harsh operations in Xinjiang and Sichuan. It has complete downhole parameters and can perform combined logging. The acoustic wave length is greatly shortened, including time difference and acoustic wave variable density measurement functions.
