Evaluation Method for Oil Content of Low Resistance Reservoir Based on Mud Logging Data
In view of the difficulty of identifying the low resistance reservoir under the condition of medium and high pore permeability,the cause of low resistance,mud logging and production application of the comprehensive evaluation of oil and gas were carried out by recording FLAIR and gas measurement,3-D quantitative fluorescence and geochemical pyrolysis light hydrocarbon.The study shows that:(1)the causes of high content bound water,additional conductivity of clay minerals,skeleton mineral conductivity and immersion of drilling fluid into formation;(2)the combination of gas measurement and fluorescence data,hydrocarbon and fluorescence data,and gas combination constitute the comprehensive evaluation of low resistance reservoir,including gas measurement and gas combination.
