摘要
从测井信息中提取油和水的重量百分比,最能反映稠油层质量的特征.用油和水的重量百分比评价稠油层等级,是一种新概念.测井评价稠油层等级的新方法,就是根据这一新概念建立的.本文论述了新方法的物理基础,建立了测井评价稠油层等级的数学公式,并且给出了评价法则和应用范例.
The weight ratio of oil and water gained from the well-logging data can characterize the quality of heavy oil zone, combined with the porosity, saturation and shale content, it can evaluate sandstone heavy oil zone effectively and provide scientific basis for the heavy oil thermal recovery (steam injection).To evaluate the class of heavy oil zone by the weight ratio of oil and water is a new concept, the new method of evaluating the class of heavy oil zone by well-logging is established on base of this new concept. This paper deals with the physical basis of the new method and establishes the mathematical formula of evaluating the class of heavy oil zone. The evaluation rule and application example are also demonstrated in this paper.
