轻烃分析技术在油气层评价中的应用研究

Application of light hydrocarbon analysis technique in reservoir evaluation

该文研究了利用轻烃分析技术评价油气层的方法。根据不同流体轻烃组成的不同,其谱图形态、特征参数均发生有规律变化,建立了原始谱图法、星状图法以及油气层判别标准,3种方法评价储层含油气性,原始谱图法快捷方便、星状图法直观形象、油气层判别标准使得解释更加有据可依,应用于生产实际,效果良好。轻烃分析技术投入现场应用,拓宽了录井服务的领域,为快速钻井条件下及时准确识别油气层,具有重要作用。

This paper studies the method of reservoir evaluation by using light hydrocarbon analysis technique. Under different light hydrocarbon fluid composition, the spectrum shape and characteristic parameters change regularly. The original spectrum, stellar method, as well as reservoir recognition criterion are established in this paper, which makes interpretation be supported by irrefutable evidence and is applied to actual production with a good result. Light hydrocarbon analysis technology is put into field application and widens the areas of logging services. It plays an important role in timely and accurately recognizing oil and gas layer at rapid drilling condition.
