基于FLAIR技术识别储层流体

Fluid Identification Method Based on the Technology of FLAIR Well Logging

常规气测录井存在脱气效率低、气测数据质量差、解释方法适应性差及解释结论符合率较低的问题。随着油气勘探的深入,传统的录井技术已不能满足井场油气显示识别、评价的需求。FLAIR(fluids logging&analysis in real-time,实时地层流体录井)技术因能够提供更为客观的高质量数据和更为宽泛的烃组分信息而被逐步推广应用。利用FLAIR更全面的数据信息改进了皮克斯勒图版,根据衍生参数建立了全烃-流体类型图版,定义了油、气、水指数并提出计算公式,并以此制作了流体指数解释图版,形成了一套适用于渤海地区的油气快速识别方法,在实际应用中取得了良好的效果。

There were many problems in the conventional gas logging technology,such as low efficiency of degassing,poor quality of logging data,poor adaptability of analyses and low agreement rate of conclusions.With the development of hydrocarbon exploration,traditional well logging techniques were not able to meet the demands of fluid identification and evaluation on the well site.While FLAIR(fluids logging &analysis in real-time)was gradually popularized because it was able to provide more accurate and more reliable data and more comprehensive hydrocarbon components.The Pixler chart is improved by using the more comprehensive data information of FLAIR,and the total hydrocarbon-fluid type chart is established according to the derivation parameters.The oil,gas and water index are defined and the calculation formula is put forward.Based on the study,a set of rapid oil and gas identification method suitable for Bohai Area is developed,and good results are obtained in practical application.
