由于秦皇岛32-6油田存在低电阻油层以及储层砂体较薄等特征,给测井解释油、水层带来一些困难.为此,笔者采用热解、全烃气相色谱和同步荧光光谱等地球化学方法进行油、水层预测.油层和水层具有各自的地球化学特征,如油层中油砂的热解油气产量高、轻芳烃含量高等.在综合研究的基础上,建立了秦皇岛32-6油藏油水层划分的地球化学标准,预测了秦皇岛32-6-4井油、水层.
Because of the existence of low resistivity oil layer and thin sandstone in Qinhuangdao 32-6 oilfield, it is difficult to interpret the oil and water layer by logging.Therefore, the author uses pyrolysis, total hydrocarbon gas chromatography and synchronous fluorescence spectroscopy Geochemical methods for oil and water layer prediction.The oil and water layers have their own geochemical characteristics, such as the production of pyrolysis oil and gas in the oil sands and the high light aromatic content.Based on the comprehensive study, the paper establishes the Qinhuangdao 32-6 Geochemical criteria for the division of oil and water reservoirs in the reservoir have predicted the oil and water layers of well 32-6-4 in Qinhuangdao.
