摘要
红外光谱分析是一种新兴气测录井技术,具有实时性强、操作简单、成本低等特点,在发现油气显示和判别原油性质方面具有独特的技术优势。通过红外光谱录井技术在镇北地区延长组的应用分析,总结红外光谱在该区储集层的响应特征,利用全烃参数、组分参数和全烃曲线形态,建立了红外光谱资料在镇北地区延长组储集层的识别方法。现场验证结果表明,该方法在储集层识别、解释评价应用中效果良好,特别是在低电阻率油层、消光油层、致密非均质性储集层识别中优势突出,较好地解决了镇北地区油水判识难题。
Infrared spectroscopy analysis is a new gas logging technology with features of strong real-time,simple operation and low cost,which has the unique technical advantages in the discovery of oil and gas shows and discriminating oil properties.By the application and analysis of infrared spectroscopy mud logging technique in Yanchang formation,Zhenbei area,the authors summed up the reservoir response characteristics of infrared spectroscopy in this area.By using total hydrocarbon,component parameters and total hydrocarbon curve shape,the method was set up with infrared spectroscopy data for identifying reservoirs of Yanchang formation in Zhenbei area.Field validation results were good in reservoir identification,interpretation and evaluation,especially highlighting the advantages in identifying low-resistivity oil layers,extinction reservoirs and tight heterogeneous reservoirs,this method solved the problem of oil and water idenfication in Zhenbei area.
