摘　　要：皮克斯勒图板解释法主要涉及储集层流体性质、储集层含水性以及非产层判断3个方面。皮克斯勒图板设计之初,由于应用范围所限,未充分考虑不同地区、不同油藏类型的烃组分特征,随着油气勘探开发在全球范围的广泛进行,针对不同地区、不同油气藏类型,探讨其方法适用性势在必行。在阐述该图板形成过程以及解释评价原则的基础上,通过实例分析了该图板以及各条解释原则的应用前提及效果,认为该图板法在原生油藏储集层的流体性质解释方面具有优势;在储集层边底水所致的含水性判断方面有应用价值;在次生油藏解释中,应该立足于油藏的具体情况进行判断;在非产层判断方面陡斜率应用价值不高;非产能区的设置不具有实际应用价值。为了提高解释符合率,气测录井过程中,应针对实际情况具体分析、灵活应用并结合其他录井解释评价方法。The interpretation method of Pixler chart mainly involves reservoir fluid properties, reservoir water content as well as non-production layer judging. At the beginning of Pixler chart design, because of the limited range of application, the characteristics of hydrocarbon component at different regions and different types of oil reservoirs were not fully considered. With the oil and gas exploration and development being carried out worldwide, it is imperative to explore its applicability in different regions and different reservoir types. On the basis of describing Pixler chart forming process and the principles of interpretation and evaluation, the paper analyzed the applicable premises and the results of Pixler chart and each interpretation principle by examples. Pixler chart method owns advantages on interpreting the fluid properties of primary reservoirs and has application values on water content judgment which is caused by the reservoirs with edge water and bottom water. During the interpretation of secondary reservoirs, the reservoirs should be judged on the basis of the practical situation. The applicable value of steep slope rate is not high in the non-pay zones judgment; the setting up of non-production areas does not have a practical value. During gas logging, the specific analysis should be made according to the actual situation, Pixler chart should be flexibly applied, by combining Pixler chart with other mud logging interpretation and evaluation methods, the interpretation rate can be improved.
