2010年三维定量荧光录井技术在冀东油田开始推广应用,基于该技术的解释评价方法地域性较强,研究适用于冀东油田的解释评价图板与标准是确保成功应用的关键。针对这一现状,首先,借助大港油田成功应用该技术的经验,在系统分析冀东和大港两个油田190口井原油样品和314种钻井液添加剂的基础上,总结出了原油和钻井液添加剂图谱分布特征;然后,经过现场对冀东油田36口井三维定量荧光图谱的分析研究,结合试油数据,依据三维定量荧光图谱特征,首次引入了解释评价参数——波长偏差;最后,通过该油田9口井定量荧光数据的统计分析,结合试油结果,得出了定量荧光对比级别分别与最佳激发和最佳发射波长偏差的解释评价图板及标准,以此为基础形成了波长偏差解释评价方法。现场应用表明,该方法能够快速有效地指导录井现场进行油气显示判断与储集层流体性质评价,解释评价符合率为82%。
In 2010, three-dimensional quantitative fluorescence logging technology began to be popularized and applied in Jidong Oilfield. The interpretation and evaluation method based on this technique is very regional. It is the key to ensure the successful application of the study on the interpretation and evaluation charts and standards applicable to Jidong Oilfield. In view of this status quo, firstly, based on the successful application of this technology in Dagang Oilfield, based on the systematic analysis of 190 well crude oil samples and 314 drilling fluid additives in the two oil fields of Jidong and Dagang, the author summed up the crude oil and drilling fluid additives Then, after analyzing and analyzing 36 wells in Jidong Oilfield three-dimensional quantitative fluorescence spectra, combined with the test oil data, according to the three-dimensional quantitative fluorescence spectrum characteristics, the first time to introduce the interpretation of the evaluation parameters - wavelength deviation; Finally, Based on the statistical analysis of quantitative fluorescence data of 9 wells in oilfield and the results of test oil, we got the interpretation and evaluation standard plate of quantitative fluorescence contrast level and the best excitation and best emission wavelength respectively, and based on this, the wavelength deviation Explain the method of evaluation. The field application shows that this method can guide the oil and gas to be judged on the spot and evaluate the properties of reservoir fluids quickly and effectively. The coincidence rate of interpretation and evaluation is 82%.
