Application of Quick Evaluation Method for Oil/Gas at Drilling Site

This paper introduces various methods and rules of evaluation for gas detection logging. For ex ample, PIXLER specific value, triangular method of hydrocarbon constituent, hydrocarbon wetness value, light/weigh hydrocarbon specific value, C₂/C₃ specific value, gas evaluation and iC₄/nC₄ specific value method etc, presents reliable evidence for quick evaluation of oil/gas layer at drilling site.
