三维定量荧光MS指数在冀中勘探重点区带的应用
|
摘要
三维定量荧光分析在区分真假油气显示、识别井内污染、随钻检测地层含烃量变化、判断含油性质方面具有良好的应用效果。由于该技术中判断油质的关键参数——油性指数依然沿用二维算法,并不能真正反映前后主次峰的峰高变化。通过对三维定量荧光分析中波长的研究,建立了一项新的参数——MS指数,应用该参数评价显示层的原油性质效果显著,并以MS指数建立新的解释评价图板,该图板在华北油田冀中勘探重点区带取得了较好的应用成效。现场应用结果表明,MS指数的建立弥补了现有三维定量荧光技术对油质判断的局限性,新方法科学、准确,是对现有三维定量荧光技术应用的完善和补充。
As the drilling speed and drilling technology advances,three-dimensional quantitative fluorescence analysis has replaced two-dimensional quantitative fluorescence technique and become a normalized analysis item of field fluorescence logging.It has good application effects in distinguishing the true and false show of gas and oil,identifying the contamination in the well,detecting hydrocarbon content change in formation while drilling,and judging oil-bearing property.The oiliness index,as the key parameter for judging oil property in this technique,still uses the two-dimensional algorithm,it can not really reflect the change of the peak height of the major and secondary peaks.A new parameter,MSindex,was established by studying the wavelength in three-dimensional quantitative fluorescence analysis.Using this parameter to evaluate the crude oil properties of the show layer has a remarkable effect.A new interpretation and evaluation chart was established with MSindex.The chart has achieved good results in Huabei key zones.Field application shows that MS index makes up the limitation of the existing three-dimensional quantitative fluorescence technique in judging oiliness.The new method is scientific and accurate,which is a complement to the application of the existing three-dimensional quantitative fluorescence technique.
