摘要
流体包裹体蕴含着孑乙隙流体性质及其在地质史中演变的信息。油层剖面上含油包裹体的相对丰度可作为一种记录常规方法检测不到的油气显示指标,反映储集层原始含油性和古油藏油水界面变迁。包裹体中水相盐度的测定能准确提供测井资料,计算原油储量所需的束缚水电阻率数据。根据包裹体在矿物中的产状和荧光颜色,能查明原油运移的时间、温度和通道,从而揭示原油的成藏演化史。
Fluid inclusion contains pore fluid property and information on its geological history. The relative abundance of oil-bearing fluid inclusion on the formation profile can be used to record the oil and gas show targets that cannot be detected through conventional methods and to reflect original oil-bearing saturation of reservoirs and migration of oil-water contact of Paleo-reservoirs. Measurement of the water salinity of fluid inclusion can offer accurate logging data and calculate irreducible water resistivity data for crude reservoirs. The inclusion shape in the minerals and the color of fluorescence determines time, temperature and pathway of crude migration, revealing the reservoir formation and evolution history.
