Ultra-High Temperature and High Pressure
Slim Hole Logging System
The instrument string of the ultra-high temperature and high pressure slim hole (EELS) logging system includes acoustic, electrical, radioactive and other logging instruments. It can be used in open hole wells and cased wells to make predictive evaluations of reservoirs and evaluate the reserves of oil and gas reservoirs in the formation. The instrument 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; the downhole parameters are complete and can be combined with Grand Slam logging; the acoustic wave length is greatly shortened, including time difference and acoustic variable density measurement functions.
