摘要
热解气相色谱技术在烃源岩和储集层评价方面具有独特的优势,热解气相色谱谱图能通过其分布曲线展现岩样中烃类的全貌,反映出样品有机质丰度及其演化程度。对谱图形态的评价以往大多采用直观定性方法,受人为影响因素较多,没有定量化的参数,增加了智能评价的难度。通过对原始资料进行处理,采用拟合方法给出量化的形态因子,将谱图数字化。再利用谱图形态因子与热解气相色谱参数总峰面积以及岩石热解参数结合,建立了滨海地区解释图板,在实际井应用过程中解释符合率由原来的78.85%上升至82.69%,效果显著。
Pyrolysis gas chromatography has unique advantages in the evaluation of source rocks and reservoirs.The pyrolysis gas chromatogram can reveal the full view of the hydrocarbons in rock samples through its distribution curve,reflecting the abundance of organic matter and its evolution degree.In the past,most of the evaluation of spectrogram forms used visual qualitative methods,which were affected by human factors,and there were no quantitative parameters,increasing the difficulty of intelligent evaluation.By processing the original data,the fitting method was used to give quantitative morphological factors and digitize the spectrum.With the combination of spectrum form factors and the total peak area of pyrolysis gas chromatographic parameters and the rock pyrolysis parameters,an interpretation chart of Binhai Area was established.The effect was remarkable in actual well application with the interpretation coincidence rate increased from 78.85%to 82.69%.
