油气化探技术在储层识别中的应用

APPLICATION OF GEOCHEMICAL EXPLORATION TECHNIQUE IN THE IDENTIFICATION OF OIL/GAS RESERVOIR

本文重点介绍了井下油气储层异常的识别与评价技术。提出以荧光光谱Ｅｍ３６０ｎｍ强度、Ｅｍ３２０ｎｍ与Ｅｍ３６０ｎｍ波段光谱强度比值、岩石酸解烃总烃，以及光谱指纹与烃指纹图谱作为识别储层异常的指标或方法。采用光谱指纹与烃指纹技术法以及酸解烃派克斯勒图解法和综合比率法对异常的油、气属性及有效性进行综合判别，进而提供油气测试层位。

This paper gives an emphasis on introducing an identification and evaluation of subsurface oil/gas reservoir anomaly. It is pointed out that intensity of Em 360 nm fluoresent spectrum, intensity ratio of Em 320 nm and Em 360 nm spectra, total hydrocarbon in acidolytic hydrocarbon, and fingerprite spectrogram as well as fingerprint hydrocarbon chromatogram can be used as an identification of reservoir anomaly. Fluorence fingerprint spectrogram and fingerprint hydrocarbon chromatogram and Parkersler figure in acidolytic Hydracarbon or composite ratio are used to identify the composite effectiveness of the anomalous oil and gas and to suggest the intervals to be tested further.
