利用热解气相色谱分析方法判断储集层性质

IDENTIFICATION OF RESERVOIR PROPERTIES WITH PYROLYSIS GAS CHROMATOGRAPHY

热解气相色谱法是结合热裂解和毛细管气相色谱分析技术,通过氢火焰检测器对热解产物中的热蒸发烃(S_1)和热裂解烃(S_2)进行分析,得到详细的烃组成资料,依据烃的组成特征及含量变化对储集层的含油水性进行判断,主要针对S_1的特征进行了分述和研究。

Pyrolysis gas chromatography is a combination of thermal cracking and capillary gas chromatography. In this method, thermal evaporating hydrocarbon (S_1) and thermal cracking hydrocarbon (S_2) in pyrolysis products are analyzed with hydrogen flame detector, thus hydrocarbon composition data can be obtained, Then water and oil properties in reservoirs can be discriminated on the basis of the composition features and content of hydrocarbon. The elucidation here concentrates on the S_1 features.
